tekwyzrd's entry for the 5th annual blf/old lumens scratch made light contest (handmade)

handmade light
alpha development designation: RPG-90

R = Recycling
P = Photon
G = Generator

90 = current estimate of diameter.

Final designation will be determined by lenses used. Current plan is for a 85mm final lens (scheduled for delivery tomorrow with the precollimator). Yes, it will be a multi-lens ‘zoomie’ using a wavien-like reflector.

+1 on that. Congrats on being the first starter. It sounds like its going to be a real blast. Smile

Parts list post. This will be updated periodically as the components are received or changes are made.

Reflector: 74mm HID xenon reflector. The opening will require adjustment to the correct angle so I will be ordering a spare. The shape is mostly hemispherical but with the sides flattened. The curvature covers the critical angle range for recycling. I have one on-hand and have gotten pretty good at trimming reflectors (thanks in part to an excellent high-carbon hook-bill knife blade – a Don Carlos 4379 made in Solingen) but would prefer to have another just to be prepared for any mishaps. The finish is excellent with no apparent flaws. Photo is from seller’s listing.

I see your going for a practical EDC Light.

If your idea of edc involves carrying a light that weighs several pounds then yes. Big Smile

Several pounds? Yeah, hang it on your belt, right next to the BLF GT! Silly

Currently waiting for delivery of an additional reflector and lenses from another member. Still debating the emitter. Conventional logic is the smallest die but I want to do something different and am seriously considering a mt-g2 to produce something more useful than a pincil point beam at long range. In a single lens light such an idea might be foolish but with multiple lenses and recycling…

I’ve been a little sidetracked lately due to concerns for a friend/neighbor currently in Michigan undergoing surgery to fix the damage done by Cleveland Clinic (botched radiation treatment and surgery for colon cancer). I honestly felt terrible that I couldn’t help OL but I was already doing what I could to help someone else as we are still doing. During my youth my best friend was a cancer survivor who lived from first diagnosis and surgery at 9 years old to his death at 22 and even after all of these years I admire and respect his determination and as this friend has faced even more difficulty I could never forgive myself if my support wavers. For this build I have to be as frugal as possible. Please pardon if the result is a bit less than spectacular.

Theres nothing wrong building a light around the MTG2.

All the best looking after your mate. Its a cruel horrible disease.

Thanks. Her situation played a part in missing last year’s deadline. Please don’t mis-interpret. I won’t miss it this time but my target is lower. As for the MT-G2, I have a feeling it may provide interesting results in a 2 or 3 lens recycling light.
