I have a 5gal California air compressor that's fairly new and it's not in my budget to replace it at this time. It works great and is nice and quiet in my basement shop. Primarily use it for blowing out the build up in small hollow forms, finish nailers, etc. But I want to be able to use the small Grex random orbit 3" sander or the new random orbit offered by Woodturning wonders. Of course my compressor doesn't have the air capacity.
the compressor is rated as5.5 Gallon Steel Tank - 3.10 CFM @ 40 PSI 2.20 CFM @ 90 PS. The Grex is rated operating Pressure 90 psi and air consumption 8 SCFM
The pnuematic random orbit sander from Woodturning Wonders per their website is rated at "Minimum requirements for air is 90 PSI and 3 CFMs"
Is their a simple and somewhat inexpensive way to add an auxiliary tank inline with my air compressor to increase capacity to the necessary requirement of the aid sanders? I still have the 30y/o old 4-gallon twin tank contractor compressor that the Cal Air unit replaced if that can be used (but I'm assuming I would need more than that extra 4gal capacity)
Any ideas, tutorial links or video links for doing something like this?
Thanks
