What about a higher temperature filament, such as nylon? I know my printer can reach the +235°C temps required to print with the material. Does the LED reach temperatures this high?

I think that would work.   If want to give it a try I would be glad to bench test a few at high amperage to see if they can be melted.

Do it! I’m sure you could sell plenty, once vestureofblood finishes testing to confirm viability.

Sorry yall! I took a break from flashlight work for a while because I was too busy but THIS SALE IS BACK ON. Please re-submit a purchase request if you had previously proposed a size and still want it. All old requests are still in the original post.

These will now be made from black acetal instead of white nylon.
Simple washers and spacers are now $1 each; centering rings are still $2 each.

Added Kenjii’s XM to XP adapters [post #58] to the new queue.

UPDATE:
These are pretty tricky to machine. The prototype is a little loose on the 219C; I will tighten the spacer pocket by up to .002” per side. I need add a deburring cycle to the program as well.

Circular pockets seem to be all the rage these days to avoid the dreaded centering ring dedome. On these larger gaskets this is an option. Which would you prefer nofearek9? Round or square?

Round pockets will also alleviate the solder bead interference problem.

I knocked those out this morning Nofearek9. They came out nice on the first try. I will PM you payment info.

This is it for this weekend. I’ll be doing another run of centering rings around next weekend so jump into the queue if you’d like some.

@Nofearek9: If you need me to add slots or some other provision like a back side pocket to allow clearance for the wires on those centering rings let me know, I can do that. Not sure what your plan is. Hammer some solid core copper wire flat and you’ve got yourself a handy flat lead.

@MG: Sounds good. I’ll get the Convoy rings modeled up with round center holes and added to the queue. Let me know if you’d prefer a square center hole.

As long as you can keep the tolerances good, round is OK, but at least with the plastic spacers it seems like the round ones have a much wider tolerance range, which often makes them end up loose.

I suppose that round holes alleviate the need to add pockets for the excess solder relief.

Ok, managed to squeeze in some more machine time for these. They came out nice though the picture doesn’t look that great. My process is getting better. I’ll shoot you fellas a PM.

I’m using 3/16” down to .020” end mills, so far.

I should add copperclad circuit boards to this thread. (contact plates, etc) I already have a bunch of 1/16” thick 4oz double sided board material. Some 1/32” 1oz double-clad as well.

My hunch is that simply punching the stars may not create a sharp enough edge to prevent shorts, but it may be ok with a little bit of cleanup. I think you could punch them close to 16mm but oversize, then use a sander to finish the job. This would save time over only using the sander. The sander method has been successful.

I have however been re-machining XHP-70 boards from 20mm to 16mm, and they do not short. The star gets chamfered on both sides. I can also do this with the LED’s pre-soldered on the star without damaging the LED. These and the colored stars will be available shortly. I really had expected the star manufacturers to offer these by now but since they aren’t, it’s about to time to fill the void.

Do you mean are turning down the actual sinkpads? If so, is it possible to get a couple? I’ve not been as successful at avoiding shorts and even when I get it working, I don’t trust led+ trace a knife blade away from shorting out.

They are sold through Mtn but it looks like they might be out of stock. I don’t have any of the stars at the moment.

Lightly filing around the edge at a 45-degree angle doesn’t do the trick?

You know… I’m embarrassed to say I didn’t even try a hand file. Facepalm I was using a dremel and trying to clean it up with a utility knife. I imagine my difficulties are a result of my methods. I had such a hard time with the first two I did that I mentally gave up on trying to find a better method. I’ll give the hand file a try on the next one.

MG and nofearek9’s gaskets have shipped. Big Smile

I closed the sale because I need to put all of my spare time into superior product offerings… starting with a run of copper S2+, C8, and D01 heatsinks. I’m running some now.

Edit: took three tries and I had to edit the machine post parameters to smooth out the thread interpolation but it’s looking pretty good now.

Since I closed the sale there has been a surge of interest, which is pretty motivating. I was not expecting that. I’ll leave it open and just do them when I can. It takes about 3-4 hours to do a batch but it’s worth it if there’s several people wanting gaskets.

Thanks MRsDNF. That’s a big compliment coming from you. I’ve seen some of your work!

It may not be as big a complement coming from me, but I also think that your work looks great! Wink

I’m glad you re-opened sales of the gaskets on a “produce when I can” basis.

Thanks wight! I try to make my parts as pretty as I reasonably can. It is the little details that the average person wouldn’t even notice, but a machinist might, that make parts great instead of just good. I was taught this by an old hand when I first started out.
