I turn a lot of salt shaker pepper grinder combination pieces for sale at craft shows. I have a 3/8 inch threaded mandrel that has two rubber bushings on it that can be expanded to hold the ID of the pieces I am turning (the ID of the pieces is 1 1/16 inch which is the OD of the rubber bushing) . When I tighten the nuts on the mandrel against these rubber bushings they expand to hold the pieces steady for turning the OD of the pieces.
The rubber is wearing out and I would like to get another set. Due to poor memory I have no idea where I got the originals. I have looked online to no avail. Even tried McMaster Carr. Nothing yet. Maybe I am using the wrong nomenclature. Perhaps they are not called bushings? I don't know but, I would really like to get another set before these ones give up the ghost completely.
Does anyone know where I might find anything like this or by whatever other name I can search for a match?
Thank you guys and Gals,
Denny
