It's like this one:

Cheap and work well. Lowish flow though, but perfect for this job.
They'll vaporize a bit of oil if the inlet pressure is not at vacuum yet, so not good for moving a lot of air.
If you buy one, get an exhaust filter with it to reduce the oil mist.

Hi,

May i ask how you prevent epoxy from being all over the base? What do your bases look like after the infusion process? Do you use anything to protect bases? Tape or so?

Thanks for your answer

I put rub on wax on the base, except for the last few mm from the edge. I take most of the epoxy of with a scraper (home made one, about 100mm wide). The last bits come off in the base grind.

The wax makes the epoxy come off easier, and I figure that epoxy would also fill the pores of a sintered base, reducing wax take up.

Recently I made a 350mm belt sander, but actually the epoxy comes off faster with the scraper than sanding. After scraping I use the sander to do the rough work before bringing it for a stone grind to a shop.
