I connect several tools to my shop vac and I use a Thien design separator.
Saw table (Eureka Zone) tools (10" saw & router) have 1.5" fittings
Rigid sanding table = 2.25" (currently w/ 1.5" stepdown adaptor)
I also have other tools, but these are representative
I have at least two 2.25" hoses (not including the one to the separator) and two 1.5" hoses: 15' and 40' (a "pool" hose with rubber end fittings)
I also have a Porter Cable shop vac with 1.5" hose - it's suction is equal or better than the Craftsman
Separator is 30G metal can, plywood top I routed, Rockler fittings - it works well, I hear no leaks
I am re-configuring things. I have so many questions my brain is melting. So, experts and/or experienced people, please help me:
Does 2.25" hose intrinsically have better suction than 1.5"?
Does a longer hose intrinsically have better suction than a shorter hose (same size and construction)?
Is it significantly better to use a 2.25" hose to a 2.25" tool rather than a 1.5" hose into a stepdown adaptor at the tool?
Is there a better practical suction test than holding the end of the hose against a 1.5# plastic box?
Does suction automatically decrease for every additional volume of air space in the system? I.e., like the separator.
Is there a good test for leakage at the couplings?
Any general recommendations? Use the PC? Use 2 different hose systems after the separator (the fittings are easily accessible)? Forget about it and ride the bike for 2 hours?
Thanks, as always.
