Jer in responce to your other thread,last post.I agree with and did a lot of reading also.Now I am stupid too.From the wood web etc,it appears guys with 20 Hp want 40Hp.Afriend has a 5X10 thermwood with a 25Hp pump.I think it is a BuschR-50630..
[url]http://www.electrolabinc.com/pdf/R5_Brochure.pdf. That pump is 20K.Still it has trouble with small parts,under 6"sq.There is lots of used pumps on the web but they still command high prices.I don't know what type of pump SS is offering rotary vane or re-gen.If you want to review re-gen prices,check Granger.http://www.grainger.com/Grainger/wwg...arch=1&sst=All
Sorry I do not have answers.If you only cut say mdf cabinet doors,a very small pump will do.For small parts the sky is the limit
