Hi all! I'm impatiently waiting for some parts to come for my Streamlight 20X build, so I got to thinking that I have a couple of 3D Mags lying around... Hmm. Copper! That's the ticket! I've made some copper core sinks in the past that work well. Why not go the whole way?
I figured that since I'm making one for myself, I might as well see if anyone has done it before. I did a search on copper Mag heatsinks and didn't get much beyond an old thread where U_235 offered them then got sick and it looks like the whole thing fell through. By the looks of that thread there may be some people here that would want one, so I will make some more if there is interest. I'm buying one foot of 1 3/8" copper, so I might as well make a few.
Here are the measurements that I use when making 3D Mag sinks:
Body ID = 1.345" Machining the sink to this usually gives a decent sliding fit. 1.346 is sometimes too tight, but not always. Mags vary a bit...some sanding (or hammering) may be required if your Mag is tighter than most.
Body Depth to switch = 1.645" I would make them up to 1.500", though that leaves no room for a driver. I would ask that you tell me the length you want.
I am willing to drill holes, machine a pillar/pedestal on top or leave it virginal for you to do as you like.
I will drill and tap all of them for a 10-24 set screw so the sink is height adjustable.
Here is an example of one in aluminum. Plain top, no holes, 1.5" long.
An example of a pedestal. It was one of my first attempts. I gave it to a friend.
I do not have any C Mags, so I would need measurements to make any for those.
So, where this stands right now is that I am gauging interest as to how many would be interested and what you would want for holes, pedestal, length etc...
I am thinking price will be in the $40.00 range plus shipping. Let me know what you think. Questions are welcome.
