UPDATE 3-16-05:

First photo of a complete LionCub body:

Of course more cuts are still to be made but this is an exact representation, aside from the finish, of how an assembled Cub will look... /ubbthreads/images/graemlins/thumbsup.gif

UPDATE 3-10-05:

Got some new pictures for you, both actual photographs of some LionCub parts now knurled, as well as CAD renderings of the upcoming LionHead accessory.

In this picture you can see the five grip bands created on the LionCub body now that knurling has been applied:

Note the teeny lil' diamond points all a-starin' back up atcha...

Here is one that just got done, still chucked up on the CNC lathe and ready to be parted:

A pic just to show there are indeed more brothers and sisters where these came from, all due to be born shortly:

But wait - what's this? Why sit around waiting while one project is going on, when we could be working on a follow up? So here are a couple of 3D renderings on the upcoming LionHead, which will transform the Cub into a light for ALL reasons:

I personally like the chunky, no-nonsense look, like a little Lion King on - steroids... /ubbthreads/images/graemlins/grinser2.gif

This beamshot of a proto LionHead on a Cub test mule graphically illustrates the throw from an Lh-equipped Cub. It will literally transform the Cub into something that replaces just about every other light I have:

It quite cleanly outthrows the Space Needle II...

Hmmm...Big Sale on my Old Lights right after the Cubs ship...? /ubbthreads/images/graemlins/naughty.gif

UPDATE 3-8-05:

The 200 PWM boards for the LionCub, programmed with the latest V.2 interface firmware, have just made their grand entrance to Hawaii...

UPDATE 3-7-05:

The first couple of pieces to the LionCub body rolled off the CNC lathes today:

The battery tube's theme was designed to be reminiscent of prior MR Bulk™ custom-bodied lights such as the VIP and LionHeart, by adding a ridged area where the light would normally be gripped, with knurling of the tops of these ridges to create separate grip bands.

The yet-to-be-made final body piece, the bezel, will carry the ridged theme as well, except they will remain smooth to create contrast while at the same time adding interest to the overall look. "This ain't no twist-on light, sonny".

Sheesh, I feel like an automobile exterior designer now...

************************************************************

Here is the proportionally correct CAD diagram of the body shape for the upcoming LionCub:

Although not shown here, there will be a cutout milled into one edge of the circumferential curvature of the bottom flare to create a lanyard passage. It is designed to still allow full, flat tailstanding ability.

The slimmed waist section will be the only knurled area. Top sections will remain smooth to allow for logo and inscription etching, as well as not interfering with the chamfered switch cutout. The switch is still located in the central body component (hereafter referred to as the Control Module).

The thickness of the integral heatsink (visible as the solid top section of the Control Module) has been made thicker than the LionHeart's to further improve thermal conductivity.

There are three o-ringed joints as in the LionHeart; however, the o-ring of the battery tube has been relocated to create a bore seal with the Control Module as opposed to the previous edge seal of the LH. This completely eliminates o-ring friction against the circuit board and ensures no twisting force will occur to cause mislocation of the switch, while still providing full waterproofing.

The overall length is tentatively ~2.98 inches.
 
Re: LionCub - First Picture (CAD)

Excellent!

It's got the cool flared tail end like a certain other small light.
 
Re: LionCub - First Picture (CAD)

Wow, nice charlie.
I like the waterproofing stuff.
I've been raining quite a bit here in CA.
 
Re: LionCub - First Picture (CAD)

Great! Thanks Charlie. /ubbthreads/images/graemlins/clap.gif

Now to update my paper cut-out.

Flared tail, knurling just where you want it, and the expected (from MR B) details like waterproofing and improved heatsinking. I'm still hoping for a minimal logo -- maybe just the maker/s' name/s. Anyway, it looks purdy. Thanks MR B for the preview.
 
Re: LionCub - First Picture (CAD)

Oh yeah, there'll be a logo all right - in fact I'm finishing up the final touches on it right now and should be able to post something here today/tonight. Also the new tradition of having the "Made In Hawaii" will be intact, as well as the "CPF LE" lettering and the "0xx of 100" serializing, etc.

Yeeeeeeehhhhhhhhhhaaaaaaaawwwwwwwwwwwww!!

Codey's a droolin'! /ubbthreads/images/graemlins/grin.gif

Re: LionCub - First Pictures (CAD & Logo)

I LIKE the logo. A big paw just seems right! Too bad the Islands aren't in the same configuration. /ubbthreads/images/graemlins/grin.gif
 
Re: LionCub - First Pictures (CAD & Logo)

Thanks Code-y, I was trying to get across the idea of a young lion's paw, a grown one I would've included the pointed claw tips... /ubbthreads/images/graemlins/grinser2.gif

Hmmm...leaving something for later are we? /ubbthreads/images/graemlins/rolleye11.gif /ubbthreads/images/graemlins/popcorn.gif

Bad Code-y... /ubbthreads/images/graemlins/twakfl.gif ...Bad Code-y...

I'm going to the timeout corner now...
 
Re: LionCub - First Pictures (CAD & Logo)

looks very nice.. with the IMS20 in there whoa, beautiful beam.. nice size.. i am sooo tempted.

Maybe we could invite Superman in and have him just mush those islands around into the correct locations to match the new logo.
 
Re: LionCub - First Pictures (CAD & Logo)

The cub's dimensions seem to be exactly the same as the ARC4 with the flat cy tail mod. I measured my cy tail mod ARC4 to be exactly 2 15/16" - basically a hair under 3". In addition both heads are 1" in diameter and the ARC is 1.75" long. From the cad drawing, the head section is 60% of the total length which would make the cub's head about 1.8" long. Both lights battery tubes are flared at the top and have knurling and the same length and probably the same diameter. The only physical difference that I can tell from the two lights is that the cub has a flaired bottom, a.k.a., KI. Overall, a nice time tested design. For a small light, careful placement of the switch will be crucial.

Regards.
