Air Chucks?
Might want to play around with this during the winter. I made a vacuum pump that work in connection with my compressor that 3 used for vacuum bagging veneer. Wondering if this could be used? Any suggestions about a homemade connection for the air?
Re: Air Chucks?
I wouldn't recommend a compressor for any vacuum set up. A dedicated vacuum pump is much preferred. Why run a 2-6HP compressor as compared to a fractional HP (1/4HP)? Save on electricity. A vac pump is much quieter. A vac pump is continuous duty in most cases - a small HP compressor may run almost continuously and overheat. Just my opinion - worth what you paid for it. :-)
Re: Air Chucks?
I don't see any problem with the vacuum venturi. When used to just clean up the bottom of a vessel or bowl, there won't be that long of run time.
Re: Air Chucks?
Agree about the typical time it would be in use for cleaning a workpiece bottom. How much vacuum is achieved will depend on leakage and I think the venturi method falls short in this category. Note that some wood types are porous so it just isn't "system" leakage. Porosity can be mitigated to a certain degree by applying some finish to seal it up but it usually isn't perfect.
