Plumbers Fins/ Some beam shots by DBCstm added to end of thread

MRsDNF, your right. I sandwiched the strip between two blocks of wood and still had to trim the edges and reflatten in a large vise. No extra time, I did not go to sleep last night but did this instead. And thank you. My ideas quite often don’t work but it’s nice when they do.

Dale, yup, I hope you get to see it up close in some future, near or otherwise.

Take some 3/4" copper pipe, cut off a ring about .325" long. Slit it so it makes a 'C' shape, and spread it out a bit so it's a tight fit into the light body. Trial fit it and file it down as needed to a height that keeps the bezel/head (or whatever, depending on the design) just shy of seating completely, so that the reflector is clamped down tight between the copper spacer and the lens.

If you swap out drop-ins often, take all your reflectors and sand the bases down so that the OAL is the same on all of them, then the fit will be the same no matter which one you stick in. That also lets you put a nice wide flat surface on the base of the reflector to mate with the copper spacer.

Plus, you also get to throw away all those annoying outer springs as you get a much better ground path.

tl;dr version:

:p

Nicely done, RBD! You sure do come up with some great ideas and some novel ways to do them. ;)

Wow. Looks like something on a Buck Rogers Atomic Disintegrator raygun 8)

That looks better than quite a few mods done on a lathe.

Well done, sir !

Very clever.

Now get some sleep! :stuck_out_tongue:

I’m only commenting again because I’m still a little amazed at the work that has gone into this and how well its turned out. For those that dont work with metal this is a work off torture and love which may not be apparent. Again nice work Mr duck.

Amazes me what some people can do with proper equipment, and what others manage to do even without! Sheer genius on a whole nutha level!

Keep up the good work RBD, I’ll take plenty of pictures for you when you’re done…no charge! :slight_smile:

Update in op.

That driver is really coming along, as is the work with the copper fins. This is gonna be totally radical! :slight_smile: Love it!

I’m still in awe off your heatsink and driver. That heatsink is a serious piece off art and l cant comprehend how you have made it let alone it looking as perfect as it does.

I can’t wait to see how this thing fits together.

That is some excellent hand work there. People just don't know how much trouble it is to do work like that until they try it themselves. It came out great! Can't wait till the whole light is finished.

I still can’t believe that you can manipulate the driver that way! Driver Magic, that’s what it is! And those fins in the pewter minimag, wow, stunning! Good job, really good work there.

Great work, very nice outputs! That should work splendidly with the XP-G2. And “hot” enough to see how those copper fins work! :wink:

What a beautiful heat sink. It is like you hit every aspect and ratio dead on as far as good looks go. I cannot believe how straight and even those line came out. Well done.

So how’s the build going? Fins are ins, driver is bad to the bone, time to cut up the battery tube? Will it stay under 100mm as a twisty? Neeeeeeeed moooooore ! :slight_smile:

By the way, the Captcha is trippin out down below, reversing the normal question and asking for a wrong answer! :stuck_out_tongue: Glad I was awake, might have tripped me up. hahaha

It’s looking like sub 90mm if I diddle the tailcap. It’s so top heavy I don’t think it’s worth bothering to keep tail standing as an option but hmmm…

I wouldn’t think tail standing would be an issue with a light so small. Certainly not for me. Besides, I’m betting a bit of Sugru would make a nice stand. :wink: AA a small thin strong rare earth magnet to the end and it will tail stand on anything with iron in it. lol

Diddle the tailcap, I always wanted a diddled mini mag. 8)

Edit: Ooh Ooh, a shiny tailed diddled finned mini mag!

RufusBDuck works in small
But his projects stand very tall
His brass rings and fins
Are the mods that are in
And his drivers are loved by us all.

That’s a SERIOUSLY diddled tail cap! And gorgeous! And will match up perfectly with the fins up top! Love it! Brilliant thinking Scott, just simply brilliant!

So now is it prudent to consider nuclear cell research? This things gonna be RBD Small for sure! :slight_smile:

Impressive, Like No Other!
