Blasting advice

[scott0031]

I am thinking about setting up a blasting facility (all cabinet work). Ideally for general usage, steel bits and bobs, ally casings, general restoration work etc etc. I have some knowledge of blasting but it is limited, so advice from guys that actually know would be helpful. I would rather learn from those with experience than learn the hard way myself.

Firstly, i don't really want to be constantly changing media for different jobs, so I'm thinking of three cabinets should cover most applications. One for heavy removal, one for medium and possibly one for bead for finishing. Would this cover most media types for every day styles of work?

Secondly, nozzles and air consumption. I know different size nozzles/guns have different air consumption. My question here is what is the difference with the air consumption vs nozzle size and what size is recommended, so I'm not standing there hour after hour and achieving little cleaning. I appreciate air consumption changes with nozzle size etc. I hope i can cover this with a screw compressor. I will be able to run something capable of up to approx 60 cfm, which i think should be plenty keeping in mind one or maybe two cabinets would be in use at any one time.

Thirdly, does anyone have an experience of these cabinets. I hate to say it after all my preaching about Chinese junk Needs must and all that. They appear to be reasonably well made for the money. Not the heaviest construction but after all its a box to contain grit plus the added bonus of a small built in filtration system . Any experience of these cabinets, is so, any down falls?


Any other advice of things i have missed or not considered?

Kind regards,


Scott

There is a company in Scotland producing blast cabinet kits, which may well be cheaper than Chinese.

Thanks for the comment. I have actually taken a look at the self build kits from various places. What i have found so far they are not really cost effective compared to the above unit. All the full kits i have found seem to be in the 400 to 450 mark. They do a job as its only a box i agree but most look what they are, a bit home made and tacky. The price you can get the above unit for has really thrown the home build ones out the window, or so i have found so far.


Kind regards,


Scott

blast media

your best bet is give vixen coatings and guyson a ring . give them your requirements then ask for there options and spec on machines and media supplied . once u have required info buy elswhere cheaper i have a few cabinets and a few pots with 3 comps one 14cfm 1- 28cfm and a 90 cfm

use a guyson at work with honite bead. its specked to handle delicate stuff but will derust landy parts after a quick wire brush. one modification we carried out was to remove the built in gloves and fit two rubber gromits with slits in and use thick rubber gloves as that cheeper and easyer to get your hand in
