just bought an old watchmakers bench that is set up for a leather
sweeps catch. does anyone use canvas? how much slack is advised?
any info on this topic greatly appreciated.
Don’t use canvas or anything that can burn so easily. Leather not
only catches sweeps, but hot bits of metal won’t burn a hole through
it or make it burst into flame.
Also, any sort of woven material will hold the finer sweeps in the
grain of the fabric. You’ll find it getting clogged with sweeps that
the brush won’t move into the pan. You’ll need to send it to the
refiner and make a new one every year or so.
