Marked Difference

As far as the pumps go those will do just fine. The most important part is to get a good vacuum container after several failures my friend and I used a keg and it works awesome with an inferior pump to the ones you have we are able to get 30hg. We just drilled some holes in the side and welded on our piping. Having less than 1" of air pocket under your mold surface is helpful also for getting the maximum definition in your pulls. Most pro vac tables will pull 18hg to 25hg

I have RT Buckets for my TK and TD and have been looking for a good mic system. Looks like you got this into an AP can you do it for a RT but I live in Arizona and won't be needing fans maybe if I moved somewhere hot like Michigan they would be useful JK!! seriously do you make a version without fans.
