Useful stuff to know:
Uses Brass, Copper, Sterling or Fine Silver tubing. Cut and anneal the tubing first
Cut tubing approximately 1/8 longer than the width of the bead hole - but beads with a more pronounced "dimple" will take longer tubes. A little experimenting will show you show you how much you can vary this. It is quite forgiving.
The tube or liner can be removed if you need to (i.e. wrong length) by gently cutting through it with a jeweler's saw (small hacksaw with a very fine blade).
Also forgiving of less than perfect bead holes. Holes with raised areas can also be smoothed with a tapered grindstone.
Should be bolted to the bench/table for stabilty.
Built-in Tool holder - can also be switched to the other side.
