You using a unit run off of a 3 HP or smaller air compressor? That is just
a toy, meant for small parts.

Like another poster said, the garnet leaves stress in parts, especially
aluminum, so I have heard.

you would need 3 of those compressors all joined together with T
pieces to get anywhere near continuous air.

been there done that. beadblasting the auster fuselage took 6 weeks
with 3 compressors.

can I suggest that you investigate trailer mounted diesel compressors
of the type made by broomewade.
you will need to brew up some adapters but the trailer mounted
compressor *will* give continuous air at full pressure.

your other problem is concerning the air pressure of your compressor.
120psi will see grunge and corrosion removed quite well.
110psi will only remove corrosion if you play the gun over the part
continuously.
80psi is a waste of time.

my mate ant took my advice and bead blasted his entire sonerai in 1
day and had it painted in that same day.
he reported needing to stop to sweep up the ballotini( you use it time
and time again) but never needing to stop for air to pump up.
