Magnetic tumbler

I ordered a mini magnetic tumber from Gesswein. Much cheaper
than a full sized unit, less than 1/2 the cost. Gesswein claims
its just as good as the larger unit, you just can’t put in more
than about 20 peices at a time. I’ll let you know how it works,
and if it actually works in 30 min. as advertised. Mark P.
