I bought some cheap ($6.69 &$6.93) C8 UltraFires from GearBest.
I would like to direct drive an XML-Hi or De-Domed XM-L2 but the pill that came with the lights is not useable. The emitter and driver are pressed into a hollow pill with no thermal mass or path. I could use a link or two for good pills.
Major thread is 22.5mm with a 1.00mm pitch
Looks like this might work for you, the body is a little longer so YMMV.
Here is their C8, very well built for 10 bux! I have 3 of them now.
Thanks MattLWard,
That looks good.
Is it because they don’t know what Copper is or do they think we don’t know the difference?
I wonder if it is a language issue… But, I think it will work for you.
well… you COULD just press in a piece of solid aluminum or copper… I dont mean “press in” with hand tight… i mean PRESS IN by slowly squeezing in with a small vise, or, tapping in with a socket…
that would turn it into a solid pill with mass.
Well that’s a good idea I hadn’t even thought of. I already ordered some brass pills but I wouldn’t mind having a few extras pills to play with. It would be fairly easy to turn some copper slugs to press into the hollow pills.
measure the inside diameter, measure a copper penny (pre-1982)
if a copper penny is too BIG? i tap the sides of the penny around it, it makes it smaller and thicker.
if a copper penny is too SMALL, i beat it on a flat, it spreads it out.
if it goes out of round beating it flat? i tap the sides… if the sides bulge a bit tapping the side in? i gently tap it flat… working like this? you can shape it and size it amazingly well with a little practice.
when i get it close? i sand it on both sides on a piece of abrasive roll paper.
i make them a HAIR too big? then tap them in with a small socket that JUST fits the inside diameter of the hollow pill… the plus of this, is that you can tap them in until the depth is just right… and, you can always tap them OUT, and re do them until you decide its perfect enough to satisfy your inner OCD…
i have a small lathe now too and know how to use it? but, this is what i did before i had the lathe. I was inspired before i got the lathe, by seeign guys like OLD LUMENS performing miracles with hand tools, like files and hammers and drill press. wink
I call it… now WAIT for it… wait… wait… okay, timing is right…
i call it…
the…
“one cent hollow pill fix”, lol
Thanks for the tip Sedstar.
Now I just have to dig through my wife’s old change jars when she’s not looking.
Coincidently my son calls me Handfile. I recently made a knife blade out of an old hand file and did all of the shaping with a hand file. The bevel is a high flat grind and took hours of hand filing. I really need a belt sander.
