Have found 2 machines and cannot locate Maker for parts list or
instrctions can anyone help label reads on both H R Superior
soldering machine#422-553 and a polishing machine #31-759a Both
are listed as 115V I would like to get to use them.
Try Rio Grande. Their 2000 tool catalog lists an electric soldering
machine (item # 503-135) on page 412. The label on it says Rio Grande,
but it looks identical to the unit (includig the accessories) I have
that is labeled HR Superior.
The polisher you describe has a tapered threaded shaft on each end of
a double shafted variable speed motor. The purpose of the tappered
threaded shafts is to make it easy to install & remove polishing
wheels of various sizes, materials, each having different finishing
compounds (bobbing compound, rouge, tripoli, zam etc) applied to them.
A gain refer to the polishing section of the Rio Grand tool catalog
for descriptions of the various wheels compounds available.
