RE: lead weight
I would recommend Ram3500 (gary Prince) and his steel powder. Very easy to use and besides lead is toxic when melted. I took some old paper tubes from wing tubes, sealed the end with packing tape, mixed up 30min epoxy and poured it in. When its cured it can be cut on a band saw without clogging up the blade. Best thing is you can cut it to any size you need. And its heavy stuff when its mixed.
