Copper Plating
unfy:
Got hole saw stuffs proper like, cut one, yay.
Need to wait until wake up before finishing off all the noisy drilling/cutting stuff.
Tomorrow night, the base should be 95% assembled (or completed).
Then it's time to figure out how wanna do the clothespin rods etc. Prolly just some 1x4's with notches cut in'em.
unfy:
Tonight should be near final assembly of the base.
Holes cut:

Hey Unfy,
Have you seen this?

Casting boolits with copper mixed into the alloy. Sounds like you can push them to about the same velocities as jacketed.

bkoenig: i'll take a look at it... seems interesting. Just as a starting point - copper melts around 2000F. Far below the boiling point of lead... but still... erf.
Wood frame cell holes sanded out and base is assembled. Power bus bars are temporarily attached. Started working out power feed diagram stuff (25 cells, 16 points to attach wires... don't come out any kind of pretty / even). Power distribution / even feed shouldn't be a problem though. Was just wanting to be OCD about purty heh.
I'll be cutting wire and crimping on ends tonight to get all of the base-frame wiring done.... this should finish the base in it's entirety (unless I decide to put a thin coat of poly over it.... will need to sand a bit more first, though... and it'll be sloppy poly of an assembled product rather than individual pieces that are then put together).
No pictures yet, I'll get pics when done tonight.
edit: Looked up some stuff. From Lee, custom molds run $175 tooling setup plus the cost of each mold blank they mill for you. $26 or so for each 2-cavity mold, don't recall about the 6-cavity molds. So minimum cost of getting a Lee undersized mold is prolly $220ish including shipping.
Haven't talked to the chuck hawks swage die folks yet to see how much they charge for custom swage dies (for undersized).
Eventually, I really will need to insist on getting undersized molds or something... :(

Looking at just the first page, it sounds quite cool. Might have to get our own thread going here for it. Too bad I don't have a second melting pot for testing this stuff out... but... do have campfire stoves that use the lil propane tanks... can just pick up a cheap & thick pot :P
For a synopsis for those not wanting to read: use copper/tin affinity to get copper to "dissolve" into tin at a relatively low temperature rather than melting point..... then add this mixture to lead to make your final alloy.
Where's all those old tin cans when ya need them :).
Pure tin looks to be expensive... $18 a pound ?
The babbits are a little cheaper... but... not by much for the higher tin content ones.
I'd have to re-look at the electrical sections at hardware stores, but I don't think there's much in the way of tin wires anymore... i think it's all aluminum now. Will need to confirm.
edit to avoid post count bloat: kinda hurt myself shoveling snow at work, going home early and prolly not fiddling with copper plating stuff tonight.
