I have a blast cabinet, but only use it for small stuff. even a swing arm can be a pain in the arse to do if its strong paint. So small stuff i do in my with glass or garnet - easy to change as mine had a drop hopper in it so out with one and in with the other in under 3mins.
Frame and swings i send out coast me $50 and done in like 15 mins. powder coat same in sating is another $50 so neither is worht the power or my time. The only thing i would say is the industrial blaster can be a bit pitty on the finish so if its soft metal or somthing you want flat then you will have to sand the frame after you get it back to level out the bumps. Also powder coater has a habit of missing the inside of tubes and gussets, so when i pick it up i always ask for his tounch up can for that paint and spray inside the front gusset and inside open tubes as i can always see shinny blasted metal and i wan it to all be covered up. Also if its a frame im using i prime it with Spray on cold galv before i take it to the powder coaters that way its sealed if they have it sitting around before they can do it ( my pet hate was going back a week later and your frame sitting there still not done and steel rusting on its own - gggr ) and also if it gets a chips when riding it only exposes the grey prime galv so its still not going to rust spot on me. They only let me use one brand on this as you cant paint over 'wet' paint, but the CRC blue can of galv has never been and issue and they love it too as it never lifts and seems to also fill in blemishes, while the powder coats sticks no problems and isnt an issue with the heat.
