moving some stuff form other forums ive posted over the time.
heres a revamp of my begginers guide with new build photos
the pump
heres mine
its a gast oiless rotary vane and move lots of air quick
i have riged up a guage and vac controller switch
the pumpisecond hand and guage was 90$NZ new guage about 35$
all up about 350$
it could do multi boards at once which is good
it sits at the end of my 3 meter long table
and the bag and rockertable sits on the table
i stick the breather into the bag and seal up the end with mastic
the hose runs across the strip of mastic with a bit more mastic over the top of the hose
and the bag seals down around the hose
very easy and quick
a 7 dollar roll of mastic will do about 20 boards
a domestic fridge pump will work
or an airbrush compressor
or and old piston typ belt driven fridge pump(these are cheap as shit 30$)
these three are slow to move air but will hold vac
it helpsto have a little vaccum cleaner just to empty the bag out quickly
the fridge pump can run continously but there is a risk the will burn out
and you need to top up the oil
airbrussh compressor will run continously but they get hot( i have one as a back up pump)
the old piston type was great it hooked up a guage and switch no problems
only drawback was low volume and noisy
