I’ve been absent from here for awhile but am back now and boy o boy do I have some news and stories that I’ll tell in a different post, I’ve got a harbor freight vacuum pump and wondering how I can convert it to work for a vacuum press. Has anyone done this?

You can connect your vacuum pump directly to a vacuum bag for veneering work. The pump will run continuously, but that should not be a problem. I’ve done a lot of veneering like that. I finally built a vacuum reservoir with a vacuum switch like the one on Joe Woodworker’s site. This makes it quieter and saves wear on the pump, but not at all necessary.

Yes, can be used.
How, depends on which vacuum pump you bought?
The single stage pump won’t easily pull enough vacuum to rip holes in veneer bag materials, so direct connection will work.
The 2 stage pump is capable of low vacuum, and will cause issues by making holes in thin bag materials. Can still be used, but you might need to add some plumbing to bleed in some air and avoid too much vacuum if you let it run continuously.
