Pressurised sandblasting pot. Needs a reasonable compressor to run it. If you have a hobby compressor it will charge the pot, but then you will probably need to keep giving it time to catch up. I used this on all my tinware, wheels and various other bits. It comes complete and ready to use. It's still full of coarse blasting media and I will through in a spare 20kg bag. £70 buyer collects from Cambridgeshire. Contact via PM or post below.
