Dangerous: we'll do the Copper Plating talk in the copper plating thread ;)
Had coffee with SFG, handed him some PC bullets for him to try in his Glock. Says he'll load'em up and try'em next week.
Stopped by Moeller Arms and got to do a quick show and tell with the PC bullets with Rod, NENick, Koz, and.... I forget the other gentleman's name :(. Impressions were good of course LOL. Had to bail from there to quickly hit hardware store for some supplies.
Picked up a pound of 1.5" (i think) roofing nails. Nice flat wide heads to make grabbing on to stuff easier etc. Also grabbed a tiny 4 pack of 3/4" angle braces. The angle braces won't be the final solution, they're far too expensive. But they're quick and were 'cheap' ($1.97 ?) for a quick prototype.
I'll fold over the angle braces, one hole goes into a bolt, the other hole the nail. folded over should get:

Basically, take a thin sheet of metal (aluminum roof flashing ?)... cut it into a 1/4 inch by 1 inch strip or something, drill 3 holes along it's length.
Nail goes through center hole.
Fold over the other two holes to line up with center hole... bolt head goes through center hole.
The folds won't be a few right angles like in the ascii art, just straight out folds. But ya get the idea.
Fun thing: how to get bolt head through two out of three holes ;). Possibly use a couple nuts instead of a bolt head on this end, whatever, don't care.
Aluminum flashing is dirt cheap, snips to cut it are cheap, drilling holes in it is easy, etc. The idea of using 3 holes instead of 2 is that the flashing probably isn't rigid enough with just a single bend holding the nail in place, i honestly dunno. i do tend to over-engineer ****.
This should get a captive nail attached to the end of a bolt without requiring a welder.
NENick: i might take ya up on the welding offer. I dunno yet. I'm debating how to get the nails attached to sheet of metal. Prolly a smaller-than-nail-diameter hole might do, i honestly dunno how much force is going to be applied to the bullet between nail heads. Shouldn't require much as far as i know. Of course, drilling holes in a single sheet and then backing it with another is a fair option ;)

An example of what in the world I was talking about.... this contraption was built with a spring simply because I don't feel like drilling a hole at the moment for tapping. In the morning.
Concerning this particular setup.. the hole drilled and the fact that it's a threaded bolt... doesn't really keep the 'needle' aligned that great. how important keeping deflection to a minimum is.... i dunno. but anyhoo.
Finding a cheap spring source, finding a way to keep it aligned better, i dunno. It might have possibilities.
a 3 sided square (or square) bit of aluminum / steel.... with holes drilled straight through would keep the spring pin aligned nicer as far as i know...
moving along... :)

One of the guys on the Arfcom thread tried drilling a hole just slightly smaller than the driving band, and setting the bullets nose down in that. He said that he got a nice sharp edge to the coating.

I could possibly go one size up on the holes I have and it'd be pretty darn close to the edge of the driving band. Still issues with cookie sheet flexing.
I'll be hitting hardware store tonight for some supplies. Will also pick up a couple more cookie sheets to cut up.
Dunno if I'm gonna use the $3-$4 a bar galvanized chain link fence tension bars or drill out some aluminum bars. I've got a bit of both. Prolly the aluminum since it's softer. Still gonna go with the bolts & tapped rods to apply the squeeze via nails on the bullets... simply because dunno a local cheap source of compression springs.
This means drilling ~70 holes and tapping them, all for only the retention mechanism... not including mounting holes. And then drilling another ~70 holes for the 'floor' set of nails.
Actually, I'll need to pick more aluminum, I need... 70 inches or so of it minimum, I've only got about 36.
So... either welding section angle iron stuffs with holes in it or shelving area. Or can just get the aluminum / steel angle iron and drill own holes. ($? depends)
Aluminum or galvanized steel bar ($3-$8).
Some flashing as cheap sheets of metal to cut up for U nuts. 3 fold U-nuts probably, but whatever. ($?? dunno. I know home depot has 100 packs of 4x6-ish sized things for $22... but surely i can avoid excess for cheaper, especially since each U nut is only 1/2 inch by 1.5 inches or so).
Should probably get another box of 6/32 or 8/32 bolts (will depend on which kind of wing nut i have more of at the moment). $3-$6 for ~100 pack.
If needed, another box of wing nuts ($3-$6).
Two more cookie sheets ($1 ea).

Prices are awesome. The first spring in the list, 100 pack is like $13, 200 pack is $15. Awesome. At least, compared to other sources I've seen (haven't dug too much).
