Black and Decker Valve refacer

[scooder]

I don't have any info other than I have one and use it, if it has the stem grinder on the right hand end, and the correct collets, rip his arm off!
Mine is the "Valve Master" I use bands cut from small (13") inner tubes as replacements for the drive bands as mine were both perished. Normal "V" belt from motor to grinding wheel.
Mind your back when you pick it (try to) up, they be damn heavy!
