The Raven- 10440 Minimag in black - Had to fix it

I like how various parts of the build look gruesomely ugly and then it beautifies in the end. :slight_smile: When I reflowed a 20mm Noctigon with MT-G2 onto the 7/8” diameter 1” long copper heat sink for my L2m, when it was done it was all one piece and working perfectly, but the heat really made the copper ugly, not to mention some flux overflow. lol

What’s the old saying “It all comes out in the wash.”

You’re off to a great start, have fun! :slight_smile:

Second bump.

I hope the masking tape is hiding bare flesh and not holding fingers on. There seems to be a thumb nail missing in that picture.
I dont have any hints for you at all boring holes out in little thin pieces of fragile steel. Looking good.

Index finger is missing the end. The tape was to protect them from the thin edges of the discs should it “grab” and spin I my grip. Ugly but it worked. The last few thou on each hole had to be done by reaming with the sanding drum.

You are one tough cookie.

Third bump.

I dont recall MTG-2 being mentioned and what a driver aye. You dont see BLF on many. Looking at it I got dizzy looking down from the top of the chips. Orsm.

It’s not often the led is as big as the driver but it’s just there for scale. It’s going in my Buck modded M1.

Fourth bump.

Are you going to solder the star in?

Ive gone out on a couple of limbs lately, so here I go on another one. You would have to solder it to get the heat away… no? All that work making the head, the fins etc.

Built from blood & tears! Nice work! Cool build to follow there.

I don’t know quite how you pull off the production aspect of all these parts being made and assembled. Envisioning it all in the first place, I guess that’s the part that gets me. How do you come up with the idea of all the various pieces parts for the build? Spend a lot of time looking at the pieces parts so they’re in your mind’s drawer ready to pull out for a build?

I’d like to solder the star in but we’ll have to wait and see. I may only be able to solder it to the post and AS5 the post. The problem is getting the fins and wire spacers to stack up to the correct dimension so that the lens is down on the star and the bezel is tight to the lens and the last brass fin as well. I’m inchinig my way toward that goal but the post and star together are as massive as a 20mm copper star with a similar surface area(2pi x r x h=2 x pi x 5 x 11 or 110 pi vs pi x r x r or pi x 10 x 10 or 100 pi). That would allow me to treat the fitting issues separately. I’ll need to leave out the led and post until the fins are all soldered in and shaped first anyway.

Whoopee! It took 4 separate brazing steps(6 if you include the oopses) and 4 soldering steps but I was able to get it put together and sanded into shape. It’s not quite done and there aren’t any new pics yet but I figured the suspense was killing you. Solder doesn’t stick to soda cans so I cut a strip and rolled it into a sleeve to keep two parts aligned. I’l use it to reflow the sinkpad onto the post by wrapping the outside with it.

Some pics.

and…

There are 4 pieces of copper in the post and 5 pieces of brass and 14 pieces of copper in the fins not including the sinkpad. 23 fabricated bits. The largest brass fin is ~23 mm OD and I used .6 mm copper wire spacing rings.

duh!

Wow! What a work of art.

Glad you like it so far. If it were crap I couldn’t give it away and wouldn’t want to. I did a bunch more on it today including some work on the optic and bezel along with a good portion of the work on the battery tube. It’ll take me another hour to put that post together so check back later.

I just reread this and I have to say Im appalled. “Depends how they stack up”… thats terrible. :bigsmile:

In all seriousness though that is coming together nicely. Even the NIBCO fittings branding looks the part.
