that plasma cutting video on your channel... holy cow!
But did you see the multi color Ti bead ... :crackup:

On another topic, I've found out that the low cost titanium EagleTac D25A (single AA) is about the right size for my pocket. Smaller than a CR123 light & larger than a AAA makes it a useful size - for me at least. But it isn't perfect as it comes from the factory:

The clip is easy enough to reshape on a grinder - but it isn't titanium. Stainless, probably 304, is my guess. The the body is grooved for better purchase:

Note the split ring used to attach the lanyard. The factory uses an end mill to cut out the attachment holes & the edges are razor sharp:

Using a split ring guarantees long lanyard life.

A nice little titanium light for $65, multiple modes & multiple output levels are user selectable. Rechargeable Sanyo Eneloop XX cells, 2450 mAh, do a good job at very low net cost over time.

A local LEO asked if anything could be done to make the Fury easier to grasp. Some drawings were done to determine the best locations for O-rings & this is what we came up with:

Image-9853934-179382897-2-WebLarge_0_c5217152146238f4e5064ad2dd905cb5_1


Image-9853934-179382894-2-WebLarge_0_ae6732fdc321eeb56552cd22b0b51b52_1


The tail cap & body are grooved on the lathe to secure the O-rings in position. Groove depth is identical to the depth of the existing scallops & flats so body & tail cap retain full strength. The hard ano does chip slightly when the cutter plunges through it but the O-ring covers that area.

If any members want this done to their Fury the cost is $42.


this is the best mod I've seen yet for the slippery Surefires. I wish I had access to a lathe right now

Thank you for your kind words. Why SF went from nice, grippy, knurled bodies to the current style is beyond me. Their newer lights like the P1R Peacekeeper have a small amount of body knurling (some SF bodies are now shorter because of the longer heads). Even so the tailcap is slick. Thank goodness the Z59 is still available.

Grooving really improves the grip on some lights. The SWM V10R Ti & the EagleTac Ti lights are both easier to grip with body grooves (IMHO).

Quick note - Running about two weeks behind schedule due to family health issues & a machine that is giving me fits at a local factory. Should be back in the shop this week.

____________________________________

This week continues to be challenging. Tuesday, for 11 hours, was spent rewiring a control pedestal for the press brake that has yet to run after being moved twenty feet. Yesterday my tech support person at the machine company suggested replacing a main control relay, not so easy when the part is 35 years old & no longer made. The replacement relay isn't in stock at any vendor (including international) & lead time is 4-5 weeks :(

Thank goodness that Schneider Electric (Square D, Telemechanique, etc.) has excellent tech support because they found an in-stock relay & shipped it out for delivery not later than 0830 this morning. Another fun day of trouble shooting & hopefully we'll see some progress.

Hope to be back in the shop next week & will update with more info when available.

Thank you for your kind words Will.

The machining was more complex than anticipated. The light has two drilled & tapped holes for a factory clip:

http://www.jetbeamlight.com/UploadFiles/201391092432259.jpg

The existing holes centers must first be located so a slightly larger 4-40 drill & tap will exactly pass through. The new hole to hole spacing is about 1.0 mm wider than the slots on the McG clip so a round needle file is used to enlarge each slot by 0.5 mm. Titanium isn't quick to file.

The Lundsford Racing Ti screws are about 3.0 mm too long so they have to be ground to the correct length & a new starting thread must also be ground.

Nearly two hours :nana:

Small Ti beads, 1/2" diameter x 1/2" long with 1/4" through hole for two strands of 550 cord. Not certain what to call this style as I've not seen this done before. Maybe Knurly-Swirly?

:nana::nana::nana:

Photo is right after machining & now they're in the tumbler for the next week.

Just finished a marathon industrial repair, 20 hours working above/below/inside a press brake (bends 1/4" steel plate 10' wide). Went into the shop to drill & tap three Mac's Customs for pocket clips & managed to break my centering microscope :sick2:

Got another one ordered & it should be here by the end of the week.

D'you think you're working too hard?
LOL, do you remember the Bruce Springsteen song "Atlantic City"? Here's the verse that I often think of:

Well I got a job and tried to put my money away
But I got debts that no honest man can pay
So I drew what I had from the Central Trust
And I bought us two tickets on that Coast City bus

So I go out on industrial repair jobs as needed & stay as long as it takes. Started the last one a week ago on Saturday, didn't get off the couch on Sunday, went back M/T/W/TH/F and was happy not to get a call last Saturday.

My machine tool distributor stopped by yesterday with a barely used Delta 14" 28-306 metal cutting & wood cutting band saw. Almost identical to my Delta 14" wood cutting saw but with a gear box that reduces blade speed to cut metals. My saw runs 3000 sfpm while his saw does that plus has 40, 60, 85, 115, 160, 220, and 335 sfpm. He'd planned to list it on eBay for more $$ but didn't want the hassle of building a shipping crate, eBay & PP fees, etc., so he "made me a deal I could not refuse" :devil:

Swapping the saws was surprisingly easy as he did all the heavy work while I watched & gave advice :D

As always with any machine tool I started at the top & worked my way down. Serious OCD is a real asset, see images below as a sample.

Too much to show & too boring for most readers but I have to say that the slow blade speeds are a welcome addition to the shop.

Whaaaaaat? Next I'll hear that you've been eyeballing cuts on the lathe while holding bent calipers in one hand and a can of PBR in the other!! HAHA LOL!

My industrial customer decided to sell the two older press brakes & buy a nice NOS from California. But ... it's 460 volt only, no 230 volt option & that means wiring in a large step up transformer. Hope to be done around the 1st of April & get back to work on lights.

April came & went & I was still at work on large machinery ... but I'm finally back on the lathe & mill. Three Mac's pocket clip installs plus one titanium bore.
