Edison was far more determined and far brighter than I ;).
Went to hardware store (Menards). Spent money I shouldn't have.
Decided to go with some small angle aluminum for both legs and retaining bars.
They had some 5"x7" 10-pack flashing things for $3. Cheaper than $25 and more than enough (although price per piece is higher).
Extra bolts and wing nuts picked up just in case. Similarly, some more 1-1/2 inch roofing nails. I went with 1-1/2 because I believe that's the correct length for the heights my toaster oven can handle (5 inches or so). If I'm wrong, I'll just have to grab shorter nails or bolts (and curse frequently).
And, for S&G, picked up a cheap-but-not-cheapest rivet squeezy gun ($16) with a relatively cheap 1000pc rivet assortment ($10). I've not done rivets before, figured I'd give it a shot. Yes, I know how to use one ... have watched plenty of AK builds heh.
unfy:
Naturally... my cheap toaster oven has only about 3.5 inches of vertical clearance, making two sets of inch and a half nails as pushing it. sigh. Will grab some 1 inch and 3/4 inch nails tomorrow.
sigh
unfy:
Picked up some 3/4inch and 1 inch roofing nails tonight, should be able to make something that works. Will be doing all of the planning on sheet metal and other stuff at home after work (sometime after 2 or 4 am) ... and tomorrow hope to actually get holes drilled and things cut out friday night / saturday morning.
Gonna copy/paste from the CB thread just some relevant info regarding teflon-ish powder coating powders. I had mentioned that it might run afoul of federal laws regarding armor defeating etc.
Basically this is important stuff relating to legal things etc, and the only reason I'm copy/pasting here instead of saying "go read these posts with a link".

I was thinking that it could help reduce friction in the barrel.
----
From Wikipedia (and yea, I realize it's not always right..)
In 1982, NBC ran a television special on the bullets, supposedly against the requests of many police organizations, wherein it was argued that the bullets were a threat to police. Various gun control organizations in the U.S. labeled Teflon-coated bullets with the epithet "cop killers" because of the supposedly increased penetration the bullets offered against ballistic vests, a staple of the American police uniform. Many erroneously focused on the Teflon coating as the source of the bullets' supposedly increased penetration, rather than the hardness of the metals used. A common resulting misconception, often perpetuated in film and television, is that coating otherwise normal bullets with Teflon will give them armor-piercing capabilities. In reality, as noted above, Teflon and similar coatings were used primarily as a means to protect the gun barrel from the hardened brass bullet, and, secondarily, to reduce ricochet against hard, angled surfaces. The coating itself did not add any armor-piercing abilities to bullets under normal circumstances.
Critics kept complaining about Teflon's ability to penetrate body armor... In fact, Teflon cut down on the round's ability to cut through the nylon or Kevlar of body armor.
---
Actually I'm thinking about getting a pound to try out; whether it's teflon or not, it has some sort of friction modifier in it to make it slicker than normal powder coat which would be advantageous.
----
Too bad idiots had to misuse teflon and many states had to ban it.
----
Only a few states did, actually, and not full bans in all:
The federal ban on armor-piercing pistol ammunition uses only the composition of the bullet's core to determine legality. However, many individual states have legislation restricting various kinds of coating materials. For example:
North Carolina state law specifically forbids persons in that state to "import, manufacture, possess, store, transport, sell, offer to sell, purchase, offer to purchase, deliver or give to another, or acquire any Teflon-coated bullet".
Teflon-coated bullets are illegal in Oklahoma under some circumstances.
Oregon state law forbids the "[possession of] any handgun ammunition, the bullet or projectile of which is coated with Teflon" while committing or intending to commit a felony.
South Carolina state law specifically bans "ammunition or shells that are coated with polytetrafluoroethylene (Teflon)".
Virginia state law specifically bans "bullets, projectiles or other types of ammunition that are: coated with or contain, in whole or in part, polytetrafluoroethylene (Teflon) or a similar product" while committing or attempting to commit a crime.
So no such laws exist here in NE, they might actually *help* body armor, probably not a federal issue. Checking the wikipedia link would prolly help if it includes a reference to body armor tests.
Moving along...
DangerousDrummer:
Today was spent casting ingots in a muffin tin. Not very exciting but I needed harder lead for the SOCOM bullets. Hope to make some PC bullets and experiment with plating this weekend. Of course the muffin tin I stole from the kitchen was the one that belonged to my wife's grandmother. ::) So much for choosing the old beat up one!

Eeek!
Sounds like some jewelry is in order heh.
I still haven't found a muffin tin for ingot casting. Proper tins that are single piece (rather than cups being individual pieces pressed / spot welded on) are really expensive, and thrift store crawling hasn't produced a result yet.
Granted, much of my lead is currently in the form of failed copper plating and already-ingotized by SFG ... so not too big of a concern ATM heh.
I've been pondering my proposed PC rig. 3.5 inches is kinda tight.
3.5 available
0.5 inch bullet height
--------
3.0 available for stuff
0.5 wingnut/bolt height (locking nut + wingnut)
-----------
2.5 available now
So... i've got 2-2.5 inches to work with for clearance from the pan and clearance to the top of the jig. Both pan and jig clearance is important because need to get powder between both, etc.
I'll hope the half inch wide aluminum angle iron / U-flashing-nut-thing aint gonna cause shadowing problems, same with being able get bullet noses coated... although the huge ground plate being not so far away, powder coat will prolly be drawn to it. I just dunno, gonna have to prolly just build it and see.
If I had 4 inches of clearance I wouldn't care :angry:
