So I have been amassing scrap copper. I have about 100lbs of it so far and I’m just about out of copper bar stock. So I figured it was time to try and consolidate some scrap into a more usable shape. Here is a video I put togather showing what I was able to come up with.
 
Nice.. I've got a small stock pile of copper and brass as well I have plans to cast some bar stock with.

Excellent!
 
Perhaps some of you should look into lost wax casting.
Simple centrifugal casting setups can be assembled pretty inexpensively.
Then, you carve your parts from wax (or inject wax into moulds for multiples) and cast parts that require very little finishing and have amazing detail.
Copper, brass, bronze, white brass, and silver are easy to cast.
 
If you us tin for making your bronze it might help with the pouring. I have been melting scrap copper in my little forge and when you add the tin sometimes when are close on temp everything goes liquid and flattens out. I found one place where you could buy tin for about $10 per pound.

How were you going to do the silicon bronze?
 
At first I was thinking it would not be worth melting and casting bars of copper. I could just recycle the copper and buy bars. Then I checked on the price of 12” of 1” round bar. Ouch thy wanted allmost $50 plus shipping. So we will continue to process our own. Going to make some aluminium bronze as well.
 
I collect scrap brass. When I have a good bit, I melt it in my HT oven. I put all the scrap in a tall, rectangular, steel container that old Bay comes in (thats a crab spice spice for you poor wretches that don't steam crabs). When it cools, I have a 2x3" ingot. Not near the scale of JT, but it is fun to do.
