This is really just a prototype…..........
I aquired the vacuum pump a year ago for $5.00….and shame on me for not putting it to work until now. All the parts shown are “found”, not specifically fashioned for this purpose.
The motivation to build something now is I have to sand ALOT of thin parts. The idea was to make a jig to hold the thin parts over a belt sander or a sheet sander without grinding away my fingertips….
The platen is a scrap part from work, which is an aluminum plate with low durometer (hardness) silicone rubber bonded to it. Attached a little piece of UHMW plastic to the top so I could hand thread the fitting into….I don’t have a 1/4” NPT tap.
The sheet sander stays put with a sand filled innertube – a Doug Stowe idea:
The pump can be turned on and off with a my foot switch:
It is truely amazing how strong the bond is when running this gadget…..I can defineately see alot of applications for this – and will be building some better jigs in the future…...very cool stuff…...
Thanks for looking.
