OK, I'm looking at eventually getting into casting my own blanks. I know that the HF pressure pot and vacuum pump are a popular combination, but my wimpy PC pancake compressor just won't do the trick when it comes to the CFM required to pull a vacuum. So, I'm looking at some options.
As far as I see it, there are two solutions: Buy a new compressor that's big and will be enough to pull a vacuum. Or see if you can buy a vacuum pump for a veneer press and use it for both applications.
I really like the latter option best, as I think it'd be the ideal solution and allow me to do veneering for flatwork, vacuum chucking for bowls, and the casting. However, I noticed that the stand alone kits I've seen for vacuum systems available online only pull 25" of Hg. I know I've seen systems around here pull around 30" of Hg. But is 25" enough? Or is my best option to buy a compressor and use the HF vacuum pump?
Thanks,
Travis
