Shot blaster advice needed
chrsgrain - 28/10/08 at 09:18 PM

Hi all,

Latest project is a 1967 TR4 restoration - and not surprisingly there is a LOT of shot blasting to do At the moment I've got one of those 'syphon' blasters with a pipe into the bottom of the cabinet, and to be honest its a bit rubbish - really slow.

Anyone got any better ideas, preferably locost, on how to get better blastin'? What about the blast pots - though the ones I've seen are expensive....

Thanks

Chris

If it's just one project, and it's bits that will fit into a cabinet (in other words, not the chassis) then I would take the bits to a commercial outfit and let them do it. You need a big compressor and the right stuff, and then you still have to spend the time doing the actual work.

I bought one of those Machine Mart cabinets from someone on this forum, but have only needed to use it once so far. It works OK but I kept running out air which was a nuisance, I reckon you would need a 3hp 150ltr compressor as a minimum.

The chassis is away being done - have got a big compressor (luckily - you're right, definitely need it). Sending things away is less fun, and also lots of the bits need cleaning, then welding, then a quick blast again, then painting... my stuff can do it, its just very (very) slow....

Thanks

I've got a plan to do this using 2 cheap compressors (gives me 3.5hp, 100l and still probably sod all FAD).

Just need to fit a one way valve between the two compressors as i've heard if you dont the bit that checks for over pressure breaks.

went to a place in millbrook to get wishbones, engine cradle and front hubs done. Only 40 quid and they done them straight away! Can't remember the name of the place but could find out if you want?

I made my own collapsible blast cabinet, using a wolf 2.5 hp compressor ( same one aldi was selling) with and aldi spot blaster gun. works reasonably well and doesn't take up much space when not in use.
