I mixed up some "clay" tungsten by using plasticine heated to liquid state and adding tungsten until it would just press together. Forms very nicely.
Also, you can use thick Ziploc bags and make any size you want by using a sealer or soldering iron to seal it.
I made some 3/8" x 6" strip bags.

Subject: [RCSE] Ballast ??
I am looking for a ballast solution for my Trinity Carbon/Acacia 3 slope
racers. I want to get them up to the max fai wing loading for unlimited
class slope racing. Lead isnt heavy enough and solid tungsten stock is
really expensive. Has anyone ever tried making ballast out of tungsten
powder? It seems to be quite a bit cheaper than solid tungsten. Can it be
compacted enough to make ballast heavier than lead?
Thanks, Walter
