I have a 25 CFM 3 Phase 200 litre compressor.
Air won't be an issue!
I have the '36 Chev Pick up body and chassis etc. to strip and clean before rebuilding.
The missus is getting toey about her 1971 F#%@ Falcon that she has stripped to a bare shell and is wanting to start cleaning door hinges, suspension components, small parts and brackets etc.
These small parts are the reason the bench top blast unit is required.
The 10 gallon is not only for the Chev and her car body/chassis etc. but also for the other 3 cars I have parked in the shed lined up to be rebuilt!
I have a rotisserie that each of these vehicles can be mounted to and the body/underside etc. is to be blasted clean as part of the restoration process.
As you have suggested, we do have a great mix of big and small parts over a number of vehicles that are to be restored over a number of years.
This is why the question was asked about parts wearing etc.
Just to make sure we get the right gear to start with that is not going to cost a heap in consumables for some simple jobs.
Thank you for the input, cannot find much information elsewhere.
