Capri Wheels

Easy to blast in a cabinet or do you think they will require chemical stripping?

yea if u have 90cfm of air and a 6mm jet

well ive worked in many places that spray cars , lorry's and use huge amounts of air tools, but nobody I know has 90 cfm compressors.
9 cfm and a 6mm nozzle is plenty to sand/soda blast. its just a set of wheels not Windsor castle.
you only want about 70psi to blast and a max of 90psi, and I would use bicarbonate of soda so no destruction of the alloy, but will get through the paint.
do not use sand, its deadly stuff.

I've got 10cfm fad and a 3 mm nozzle on my pressure pot which is plumbed into the blast cabinet. This setup takes way too long on modern wheels with a powder coat primer that's why I'm asking. I have to out source chemical stripping until I get my heated strip tank up and running and the funds to actually fill it. I was hoping these would be easy to blast bare but if not as it appears I will just send them out for stripping.

I use AO for blasting, gives the desired profile for powder coating.

9cfm and a 6mm nozzle no way. u need at least 14cfm and that will only run a 3mm nozzle and wont even hold 90psi pressure i run a 28cfm on a 3mm and it is well enough and comp cuts out but still 2 slow for wheels i run the 6mm jet on a 90cfm comp and have blasted hundreds of wheels with it grit sand and beads

Here is a good reference chart for cfm to nozzle size and psi

Pepper pots an a 2.8 injection. The special had the lsd and the Seven spokes. Five speed gearboxes were in both.I acquired a set off pops which are in a poor State. The Seven spokes are in fine fettle however.
