Tractor Supply sells a cheap blasting cabinet if you want to do it yourself. It works pretty well, and is a handy tool to have. You will need an air compressor to use it though.
Harbor Freight has a nice selection of them. The larger units need a pretty large compressor so I got a small unit with a hand gun and I catch the media in a cardboard box. It's not fancy but it works! They carry all kinds of media, too. Check online to see if anything looks good to you.
It was a shop way out on Dyer....i think it was AAA machine shop.....been many years....lotsa head trauma...lol.....but, I think it is no longer there. Try Show-n-Go on Dyer. If not, they can point you in the right direction. There are a couple out on Lee Blvd. if you are on the eastside. Sorry, I have been out of the hot rod scene for a long time....don't know what is still around.
I have a large industrial bead blast cabinet at the house that you can use. You may have to help me clear a path to it as I haven't cleaned the garage in years but what do you expect for free. Let me know.
