If you can find one. Old Benson & Hedges rolling machine works well. Never had much luck with the Zig-Zag or Top rollers which is a clone to Zig Zag machines. But I've always thought if somehow I could shorten a Top machines width so to barely accommodate a cast? It may be useful for the purpose.
To be honest. To date. I have never seen a boolit rolled tighter than those I've wrapped by hand. Although if I'm unable to roll years from now. No doubt my wife would help me out.
