    I won't have much access to the internet, next few days. ...back to Vegas for Dad's big Memorial April 25th, 2pm UNLV Alumni bldg. Will try and fit the 36 inch in the trunk of the KIA again, and use the tripod this time for better beam shots. Otherwise I can only fit the 7 inch, 35 watt HID Cyclops wanna be in the car this time.

    Oh, wow!

    Back from my Road Trip to Vegas.

    Got some really good beam shots of the Local Ski Resort just 30 minutes outside of Las Vegas, where I learned to ski as a kid. Beam shots vary in distance from two miles to one mile and a few half mile and quarter mile bright shots. It snowed a little when I arrived late afternoon, a nearly full moon was visible, at night, for the beam shots. (This thing will really light things up when I get the 1000 watt HID.)

    Will post photos next few days.

    What made you christen this light "Gorilla"?

    The fact that it has a red backside seems to suggest Baboon would have been more appropriate

    Awesome work though, looking forward to seeing your latest beamshots.

    The "Gorilla" name came about for several reasons. The basic look while designing the 36 inch searchlight, in AutoCAD 3-D Modelling, reminded me of a Gorilla I saw while watching a Nature Show. The Gorilla, with it's big round stomach and chest with arms hanging to the side but curled inward like Gorilla's often do...looking like the arbor, while it was doing it's thing, reminded me of the 36 inch searchlight.

    Overall, the 36 inch Searchlight seemed like a big Gorilla in many ways.


    The red color, was to act as a warning of the somewhat sharp jagged finish of the fiberglass, kids kept getting too close...curious...and I didn't have much of other colors left... ...Plus the time allotment; I could use the shop space, was drawing to a close, and I didn't want to run to the store and use up any more time than needed.

    I really did do this whole sequence of searchlights on a shoe string. I would like to take it to the next level and make these reflectors, lighter weight, smaller, and better optically, but money and the economy are quite a challenge, right now.

    Thanks for the good word. I will post photos next few days, when my photo buckets allow more photos, (can't afford to go pro yet...).

    The Latest Beam Shots:

    Towering over Las Vegas on the North West side of town, if taking HWY 95, the highway that goes by the "Test Site" and "Area 51"; take turnoff State Road #156 up to the Local Las Vegas Area Ski Resort.

    A couple days later, (with nearly a full moon again), The ski resort area was lit up by the Gorilla Searchlight.

    Here are some of those results with the 100 watt HID:



    Mummy Mt. & Las Vegas Ski Resort tower above Las Vegas


    This is how Charleston Peak and Mummy Mountain, (taller than the Cascade Range volcanoes of Oregon and Washington state), looks from my hotel room in Las Vegas. Here the mountains are about 35 miles away. This is where I first learned to ski...back in the 60's and 70's




    Mummy Mt. & Las Vegas Ski Resort fifteen minutes away


    This is how Mummy Mt and Las Vegas Ski Resort look from the Tonapah Highway, or about 15 minutes drive. You actually drive past Mummy Mt. to enter the Lee Canyon area and the Ski Resort.


    Panoramic Shot of Mummy Mountain and Las Vegas Ski Resort

    Las Vegas Ski Resort otherwise known as "Lee Canyon Ski Resort" has three chair lifts. The two main chair lifts are a each 3/4 of a mile long with the base terminal about a quarter of a mile from camera location.

    Mummy Mountain couple days before Beam Shots


    Mummy Mountain, 11,460 foot tall, as seen a couple days before the Beam Shots were taken. This mountain can be seen over a hundred miles away from an airplane.


    Las Vegas Ski Resort in Lee Canyon


    This is the Main Upper Parking Lot and Shuttle Bus turnaround. Not much by other resort standards, but in my younger years, this parking lot was a long walk to ticket counter, seemed big enough and being just a thirty minute drive from Las Vegas, is a great place to go. This is where the 36 inch Gorilla was let loose to light up the mountain sides


    Here is where I learned to ski as Child


    This is the Main Ticket, Bar and Grill, Rentals and Ski Lift Loading Area. Not much by other resort standards, but in my younger years, this place was intimidating, and being just a thirty minute drive from Las Vegas, is a great place to go.


    Beam Lights up top of Main Chair Lift


    The 36 inch Gorilla lights the Main Chair Lift Top unloading terminal. The nearly full moon makes the whole mountain somewhat visible. The light beam travels about a mile to this location.


    Beam Lights up top of "Extreme Vertical Drop" ski run


    This little seen ski run is seen much better than in photos when the Gorilla was aimed elsewhere. This little run, lit up by the Gorilla, is a Black Diamond run for this resort, (intermediate for other ski resorts). First time I skied that run, I was terrified.


    Beam Lights up Main Hiking Chute above Main Chair Lift




    Here is one of the 'Slide Paths' the Las Vegas Ski Resort would like to expand the #1 Main Chair Lift to. This patch of snow is 1-1/2 mile(s) distance from the 36 inch Gorilla. The beam lights up a good Extreme out of bounds Ski Run and is a good Summer hiking area.


    Avalanche path above Chair #2


    Here is one of the 'Slide Paths' the Las Vegas Ski Resort would like to expand the #2 Chair Lift to. This patch of snow is 1-3/4 mile(s) distance from the 36 inch Gorilla, and is almost completely darkened by the shadow of the upper mountain ridge as seen in other photos of this location.



    Gorilla Lights up Mummy Mountain, LightSward checks focusing plate


    Even though it was below freezing in this photo, I was actually sweating, I am well bundled for this Beam Shot series, having been a Ski Bum for many years and skiing all the Black Diamond runs I could find. I am attempting to adjust, the beam, focus, a little better in this photo.


    2 Beams compare near top of "Mummy Mountain"


    The 36 inch 100 watt HID Gorilla is to the Left and the dimmer beam to the right is the 7 inch 35 watt HID Cyclops, compare near the top of Mummy Ridge. Imagine the 36 inch Gorilla with a 1,000 watt HID.


    Beam Lights up Mummy Mountain, assistant moves light for me


    Here the 36 inch Gorilla is aimed near the top of Mummy Mountain, over a mile beam travel distance. My assistant is keeping watch over the Gorilla, while I operate the camera.



    Beam Lights up near top of "Mummy Ridge"


    Here the 36 inch Gorilla is aimed at a Ridge, over a 2/3 of a mile away. This is a ridge I took many hikers on Mountain Tours several decades ago.



    A thousand foot beam lights up the nearby hillside


    To get an idea of how bright this beam is, I aimed it to a nearby point on the hill, about 1,300 feet away. Remember, this is only a hundred watt HID.



    Beam Lights up Mummy Mountain, Assistant aims light for me.


    My assistant didn't dress well for the cold and had to 'layer up' several coats and pairs of pants. It was below freezing at this time.


    LightSward inspecting the 36 inch Gorilla Searchlight

    Here I am checking on the 100 watt HID, 36 inch Gorilla's focus at Mummy Mountain and Ridge, over a mile away. I need to adjust the 'focus', it seems to be focused at about the half mile point here, and spreads a little, as it reaches over a mile in length to target. The light is competing with a nearly Full Moon, which helps light up the surrounding landscape.


    North Mummy Mt. Ridge


    Here the 36 inch Gorilla is aimed near the top of Mummy Mountain, over a mile beam travel distance. My assistant is keeping watch over the Gorilla, while I operate the camera.


    Beam Lights up near top of "Mummy Ridge"


    Here the 36 inch Gorilla is aimed at a Ridge, over a 1/2 of a mile away. This is another ridge I took many hikers on Mountain Tours several decades ago.



    Beam Lights up near top of "Mummy Ridge"


    Here the 36 inch Gorilla is aimed at a Ridge, over a 2/3 of a mile away. This is the ridge I took many hikers on Mountain Tours several decades ago.



    Beam Lights up Lower "Mummy Ridge"


    Here the 36 inch Gorilla is aimed at a Ridge, over a 2/3 of a mile away.


    Beam lights up frozen water fall.


    This frozen patch of snow and ice is sometimes a small waterfall in the Spring and early Summer. The beam travels a mile and a half, (1-1/2 miles) from Searchlight to target here.



    Map of Beam Paths in Horizontal distances only


    Map shows approximate horizontal distances from 36 inch Gorilla Searchlight location to various points on the surrounding mountain locations. Searchlight is at about 8,600 feet elevation and the highest point is around 11,450 feet elevation or about 2,850 foot difference. Basic Trigonometry shows the beams travel about 25 percent average farther than the indicated horizontal distances, (the farthest horizontal distance about 9,600 feet, total distance around two, (2), miles.



    Beam Lights up Lower "Mummy Ridge"


    To get an idea of how bright this beam is, I aimed it to a nearby point on the hill, about 1,500 feet away. Remember, this is only a hundred watt HID.

    Popcorn Re: 36 inch Gorilla

    I've made some 'Big' changes to the 36 inch Gorilla light...a much higher wattage light bulb with a 4 mm arc area, a special Electronic Ballast said to make bulb 20 to 30 percent brighter, and supposedly last longer. I hope all works, and I have something to show at this weekend, Washington, C.P.F. get together. Fingers crossed...lots of reconfiguring, UV and ozone concerns with this Hot Re-strike, fast start capable bulb, installing cooling fans etc....

    Naughty Re: 36 inch Gorilla

    Did a bit of a quick installation of the high wattage bulb, about twenty hours work, building UV protection, added forced fan cooling through the bulb area, and being a double ended bulb allows for almost instant re-strike ignition.

    Beam looks great, a bright greenish blue. Beam needs more focusing, which I didn't do, because, Bulb starts up just fine, brightens quickly, but after the bulb reaches almost full brightness, it starts flickering, and the arc starts wandering around to different parts of the electrodes, making it too hard to focus precisely. I think the ballast is putting out the wrong voltage and current for this type of specialty bulb. I purchased a ballast that was suppose to automatically adjust to a wide range of bulb types, plus it has various output settings that did seem to help minimize the "flickering". Ballast stayed cool during the run. I may have a way to reduce this flickering. Overall, impressive, lights up objects a mile away on a hill top overlooking my home.

    Maybe at this weekend's Washington get together, someone can shed some 'light' on this issue, but I may have to get a more 'bulb' specific ballast for a 700 watt:

    OSRAM, SharXS HTI 700 W/D4/75.

    Technical - Electrical Data
    Ignition voltage 3.0/25 kVp
    Construction voltage 70 V Lamp voltage 70/73 V 2)
    Construction current 10 A Rated wattage 700 W

    Suppose to act like a brighter bulb, literature claims.

    Had a good night looking at all the lights at the C.P.F. North West get together Saturday. Amazing how far LED technology has come...some really bright new lights.

    Fired up the Gorilla with a 700 watt small arc HID. Made a nice beam.

    I need to adjust the focus, once the flickering subsides. I have to work on the ballast issue, the bulb only likes 70 volts, but the "auto-adjust', "Lumatek" ballast is pushing 90 volts or more, which make the light flicker a little bit...eroding the electrodes...???

    I'll post a couple photos later today/tonight...

    Thumbs up Re: 36 inch Gorilla

    Here are just a few of the installation and reconfiguration photos of the 700 watt HMI short arc HID, along with Beam Shots from the CPF get together in Renton, Washington. Even though there are some ballast/bulb matching issues, the light was impressive...I didn't expect the brightness I obtained.

    Popcorn Re: 36 inch Gorilla

    Hope the 700 watt HMI Osram short arc bulb Beam Shots are fun and interesting to look at.

    The ballast and bulb are not a perfect match, and thus I was 'aging' the Osram Sharx HMI bulb quickly to the point of early retirement. Hopefully I put the bulb back in the box before total death.

    For now, I have installed a shorter arc version of a standard HID Metal Halide "GROW-MASTER", 'Deluxe Blue' 600 watt, bulb, from the local indoor nursery supply,...lots of blue light like the Osram Sharx 700 watt HMI bulb. (arc on the Osram is listed as: 4mm, Temporary Replacement bulb; Grow-Master bulb: is 55mm...much bigger arc area. Actually makes a very bright, blue and fairly narrow beam, Lumen wise, the small arc 700 watt HMI puts out about the same lumens as the 600 watt HID standard arc bulb. It makes a very similar beam, just not quite as well focused and penetrating as the Osram, but very similar in appearance, and bright!

    the 700 watt Osram and the 600 watt Grow-Master; are so bright, the 35 watt HID Cyclops that I use as a comparison light, is virtually invisible next to the Gorilla with these higher powered bulbs.! Eventually I do want to put back in the Osram Sharx bulb, or a 1,200 watt HMI bulb, (short arcs basically don't come in 1,000 watt), but for now, the performance of the Grow-Master bulb is quite impressive, less expensive, less problematic, doesn't require a cooling fan, (but I use one anyway)...

    In the next few days I'll post some Beam Shots of the 600 watt HID and compare to last weeks CPF Washington get together shots of the 700 watt HMI.

    Next week or so, I plan to fire up the;

    . 7", 35 watt HMI, HID Cyclops,
    . 24", 100 watt HID LightSward,
    . 50", 400 watt HID Monster,
    . 36", 600 watt HID Gorilla,

    ....and compare all these in a photo shoot.

    I'll post these soon.

    Naughty Re: 36 inch Gorilla

    For several reasons, I've temporarily installed a 600 watt HID 55mm arc sized bulb, to get me by; until I resolve the 700 watt small arc ballast matching issue. As you can see the beam is a little wider, and fades a little bit faster throughout it's length. ...Still impressive to see this thing. The photos are from automatic setting, manual hardly shows beam, no matter the adjustments...max, etc. I will do some distance shots soon.

    Also: I finally did some Beam Shot Comparisons of the; 35 watt HID, 7 inch, Cyclops, to the 100 watt HID, 24 inch, LightSward, and the 50 inch, 400 watt HID, Monster, to the newly lit 600 watt HID 36 inch Gorilla, and got some good beam shots. Here are some of them.

    600 watt Gorilla slices the night


    Here are great perspective shots of the 600 watt HID Gorilla. I recently manufactured an all steel 'Yoke" to replace the wooden one seen here....I'll show photos when I photo graph the next set.








    600 watt HID Beam Shot


    This photo shows the 600 watt HID beam pointed away from the viewer, you can see the planet Mars, near the Beam Tip. Searchlight is a hundred feet away from camera, other side of trees.







    This photo shows the 600 watt HID beam pointed away from the viewer. Searchlight is a two hundred feet away, behind trees.






    The 600 watt HID Sun Master bulb, nice job lighting sky and some clouds, with the blue-white beam. In the grainy sky photo, shows the 600 watt HID beam shining over head.



    Brand New 600 watt HID Sun Master


    Photo of the Reduced sized arc tube and outer globe, of the regular style 600 watt HID brand new, out of the box Grow Master bulb; almost ready for it's first fire-up and "seasoning"! Took some unique primary reflector angle designs to help make the beam as narrow as it is, for such a big arc area!

    Price of the Sun Master is about half that of an HMI short arc, or about twice that of a regular HID of same wattage. The physical size of this bulb is smaller than a regular 600 watt HID and thicker outer bulb glass, makes this more robust for the abuse it may endure.


    600 watt Gorilla Left side 400 watt Monster Right


    Here you can see the Monster and temporary 600 wt. Gorilla battle it out for night time dominance, (100wt. LightSward Beam, can barely be seen intertwined with the 400 wt. Monster Beam. With all the Spring growth on the trees, it is difficult to 'aim' the Searchlights in an even pattern and not bother the neighbors too much).





    Here is a great perspective shot of the 600 watt HID BEAM from the 36 inch Gorilla. Though not as well focused as the partly focused 700 Watt HMI, this bulb puts out almost as many lumens as the small arc. Beam does not travel as far, but still puts on quite the show. Some Local High School sport teams may be interested in buying one of these with their LOGo on it!!!


    LightSward top, Monster Middle beam and Gorilla Bottom Right


    Here you can see the 100wt HID, Light Sward on Top, 400wt HID, Monster middle and the bright blue-white beam, lower right, is from the 600wt HID, Gorilla.


    600 watt Gorilla compares to 35 watt Cyclops


    The 600 watt HID Gorilla lights up the upper part of a tree that is 450 feet away. The much dimmer 35 watt HID Cyclops is on a closer tree at only 350 feet away!

    Reflector, UV, and ozone collector


    The primary reflector has been designed to focus the wasted back light through the middle section of the arc tube, to give it a brighter appearance to the main reflector.



    Part of 600 watt Grow Master HID visible


    Here you can see the 600 watt bulb, nestled up into the electrically insulated primary reflector, which is designed to reflect and focus the wasted light back through the mid section of the arc tube, to the Main Reflector. This makes the arc center more brilliant relative to the Main reflector, making a slightly thinner, brighter beam.



    600 watt bulb is protected by a Coleman Globe


    600 watt bulb is protected by a Coleman Globe, which is designed for extreme temperature changes and uneven heating...cost five dollars!!!...works great to shield UV light when using 'unprotected' double ended HMI bulbs.



    glowing arc tube, cools down

    Here you can see the arc tube cooling down after a hard nights work.


    Here are some photos of the three main searchlight I've been working on this past year plus.

    Thanks for the good words.

    It's always a hot new item in the making....I've just finished a new metal Yoke and getting ready to match it to a rotating platform.

    Admittedly, this beam from the 600 watt HID and the 700 watt HMI is quite warm from the Infrared Heat radiating from the arc tube. I always think of HID and HMI as not making much heat, which at the 400 watt range and lower, I don't really notice it, but 600 watts and above, there seems to be a lot more I.R. given off.

    This light, (600 watt HID or 700 watt HMI or some other bulb version of the Gorilla), will definitely be used, as an advertising Searchlight, at the: "Born Again Sage" Punk Rocker Movie my brother produced, when it opens at the Portland, 'Hollywood Theater', end of Summer,.

    I really like the Gorilla, because it combines the strengths of several designs, acts and looks like a bigger light, yet small enough to fit in the back of my compact car for long road trips.

    The Hollywood theater looks dark and lifeless without Gorilla.

    My next light...The Bar-B-Q ??? LOL .

    Thanks.

    My neighbors have been very positive and supportive of this.

    I'm think the condominium owner above my shop has been bothered by an occasional very bright light beam streaking across her bedroom window. I very much try to limit the time I outdoor test the lights. For the mile Beam Shots, (when I drive around the streets of town, to see how far I can see the beam), I place the searchlight on the upstairs deck, where the beam source is somewhat hidden by trees and bothers the least amount of people. Sometimes, during the test, many vehicles will drive into our 'no outlet' neighborhood.

    The winter has early nights, so it is easy to test the light with out anyone really being bothered, since people are just coming home from work and are too busy to notice. But sometimes in summer, with the late sunsets, I may be 'testing' the lights, l sometimes hear the clank of window blinds closing.

    I do my best to shield any occupied windows from the Searchlights, and if I think the beam might be an aircraft issue, I have a direct phone number to the FAA I can call, (they prefer at least 48 hour notice, so they can be sure to let any affected pilot know where to go get blinded by the beasts). As a member of the AOPA, (Aircraft Owners and Pilots Association), I don't want to upset any Captains.
    ......

    Overall I have great neighbors!

    Here is the MH, (HID) electronic Lumatek Lighting ballast I've purchased. I paid less than the MSRP listed below. Very Fast Start-up, and bright!!! This thing fires up the 600 watt bulb to full brightness in very little time...very fast! I've watched this thing fire up the regular 600 watt HID bulb in about a minute. Manufacturer claims:
    ...Fast start-up ...It reaches full brightness in under one minute; magnetic ballasts typically take about fifteen to twenty minutes.....

    (I changed some wording in the following as indicated by italics.)



    Not just your standard eballast the new Dial-A-Watt Lumateks have advanced dimming capabilities and are able to power different wattage lamps on the same ballast making them the most versatile ballasts available. The 5th generation Lumatek ballasts produce the highest operating frequency of any eBallast on the market today and offer unmatched performance. Now you can dim your lamps which can be a great way to deal with heat issues in your Searchlight and to help control your electricity bill. You can also use different wattage lamps by setting the dial on the ballast to the desired output power and putting in the proper wattage lamp. Note that both the input and output power of the ballast is changed when you select different settings.

    For example when you set the dial to 600W on a 1000W Dial-A-Watt Lumatek the ballast performs exactly the same as a regular 600W Lumatek ballast.
    This a great feature for Advertisers that want to use a 600W MH lamp for one Searchlight such as the Gorilla and then switch over to a 1000W HPS lamp when it’s time to go Disco.

    Lumatek makes the only dual-voltage eBallast available that produces the same lamp power when used on 120V or 240V.
    This is a major advantage considering that a typical dual-voltage eBallast losses as much as 15% of its output when used on 120V.
    All Lumatek models are generator ready and are capable of being used on 208V three-phase power.

    Lumatek has been a long standing pioneer in creating innovative lighting technologies for the Searchlight Industry.
    Lumatek offers the most complete line of dimmable multi-wattage ballasts on the market.
    Sold in more than 40 countries Lumatek is the world’s number one selling ballast.

    Lumatek 240V 1000 Watt Electronic Ballasts burned the 2 test bulbs we tried visibly brighter to the eye than a regular coil/core ballast!

    Why choose a Lumatek Electronic ballast over a core-and-coil (magnetic) ballast?
    - Fast start-up ...It reaches full brightness in under one minute; magnetic ballasts typically take about twenty minutes
    - Completely silent ...you have to put your ear up to the ballast before you can detect the slightest sound
    - Small compact design ...600watt ballast weighs less than 4.5 kilos compared to almost 20 kilos for magnetic ballasts.
    - Produce less heat
    - Cut-off circuitry ...Automatic cut off when a short is detected. For ultimate safety.
    - Longer bulb life...Lumen output loss over time is dramatically less than with magnetic ballasts
    - Fully interchangeable ...Lumatek ballasts can light both HPS and MH bulbs

    More lumen output...20%-30% more lumens output...More light equals more people will see the searchlight.

    There are no fans to break down or make noise; fan cooled ballast's have a very high failure rate. Lumatek ballasts are very, very reliable. Which is why we offer the excellent warranty.

    The ballast can be mounted in areas of high heat. Up to 140° Farenheit.

    - Every Lumatek ballast is burned for 12 hours at the factory
    - Excellent three year, full exchange warranty
    - Lumatek ballasts are 8% brighter than ROM and future ballasts
    - No fans to break down after 1 or 2 years
    - Safer - The Lumatek ballast is completely sealed from the inside

    Ballast comes with 15' Lampcord !
    Most companies add $35 for this cordset


    This ballast will run a HPS or MH 1000 watt Bulb
    When Selector switch is set to 600 it will run a 600 watt MH or HPS bulb

    The Dual Voltage Ballast comes with a 120 volt power cord ( regular 3 prong) or special order 240 volt cord.



    New Switchable / Dimmable 10000 watt ballast
    Will Run 1000 watt bulbs, 750 watt bulbs & 600 watt bulbs
    Price: $349.95
    326.20 USD

    This combination seems to work well, and will get me through until I get more $$$ to upgrade.

    Great project & thread LS!

    Has me wondering about all the old dishes we have around the place...

    Like the one we used as a gazeebo roof...

    Great beam shots in a nice setting.

    Thanks. It has been much fun!!
    Dishes, pots and pans, salad or mixing bowls can be quite useful in ways not always evident at first glance. One of my first searchlights used a large shiny mixing bowl. It just happened to have a virtually perfect parabolic shape.

    New rotating platform and yoke are mostly finished for now. Looks great! I'll post photos next few days when one of my photo buckets allows me to put more photo on.

    At long last, a few daytime photos and a video of the Gorilla's new panning mechanism. The panning mechanism rotates a full 90 degrees from side to side. I will upgrade it to a full 360 degree pan in the future. For now 90 degrees is plenty of beam movement for the venues I usually provide searchlight service to. Usually there is a building obstruction, trees or regulated air space I try to avoid, making the 90 degree pan perfect for many of these situations.

    36 inch Gorilla Searchlight, on new yoke and stand





    This stand pans 90 degrees, left to right, working well in downtown areas and many strip malls. Easy to transport the whole set-up in a small car.

    This video shows the 600 watt special bright HID fast start 36 inch Gorilla Searchlight on it's new panning mechanism. This powerful, homemade searchlight is used to open new local film fest and night club promotions, along with small business openings and sales events!
    (more)





    The old wooden Yoke and Stand will temporarily support the 50 inch Monster, during it's new Yoke 'fitting'.

    Part of the original rotating mechanism and sheet metal, used on the searchlights, and metal mixing bowls, I briefly considered using as searchlight reflectors, a few years ago, now used in this 400,000 volt Van De Graaff Generator. I constructed this high tension generator from junk, around the same time I built the new Searchlight Yoke. I Captured this little 8 inch beauty yesterday. The Large Sparks actually help relax and soothe sore, tight muscles.

    Shorter, but way intense spark, loud pop!

    (400,000 volts are expected on a dry day, but Portland, Oregon's constant somewhat humid, rainy days, makes the sparks much smaller, around 200,000 volts or less. Still 4 to 6 inch sparks are common with built in dehumidifying heater.) Lights up fluorescent bulbs with-in three feet, just sitting in box.

    Ooo Re: 36 inch Gorilla

    Just a quick Note:

    I will show off the 36 inch Gorilla at the Movie Premiere of my brothers movie "Born Again Sage", but there has been a slight delay filming the last and very important scene, (Insurance and permit issues of a night club). September will be the new opening month, and at the Laurelhurst Theatre 2735 East Burnside Street, Portland, OR 97214(503) 232-5511‎, and then it will show at the Hollywood Theater later in the month.

    More info as the film is completed.

    Wow! That's very cool.
    It must be very rewarding designing and building someing like this... learning from your earlier projects and applying this knowledge. A huge effort, well done.

    Thanks for the good words.

    This has been very rewarding, and has helped me keep my sanity, during the slow work schedule, I've been enduring for the last few seasons.

    Cheers!
