[TheForge] LG Mechanical to Air conversion

Thu May 30 21:05:02 2002

Dont rule out a 4" cyl entirely, with a 1" rod its equiv to a 3 1/2" bore in
area, and you could run this size at quite low pressures I'd imagine
(50-60psi), so 25cfm or so might cut it. Mabey Ive just got "bore envy" with
my 2" :)
