Re: how much psi for sand blasting?
I would never do it again... blasting cabinets are great, big items are a PITA, super messy and still have to buy the media and mess with moisture, psi, cleanup etc...
shop around and avoid the high end places that use garnet or plastic media... good old fashioned sand or coal slag (in my area) works great for the frame, axles, springs etc... Give them a bunch of stuff in bulk and it might bring the per item cost down...
