Hi folks. There are dozens of threads in here regarding blasting set-ups and I have read the bulk of them. That being said, I’m hoping to compile a lot of them into a single build thread - so please bear with me. so... I’m on a domestic electricity supply and so far I have a nice Fiac 14CFM 3hp belt-driven compressor at 14CFM (not FAD), filling a 150 litre tank. Being a bit on the small side, I’m topping this up with a second 14CFM pump and motor that will kick in at a lower pressure. Both air supplies will be plumbed into 22mm copper pipe, via a PCL 100 whip hose and will eventually be displacing 28CFM (somewhere around 18-20CFM FAD), feeding a generic Chinese blast cabinet like this: Now. There is an excellent video series on a YouTube channel called Ray’s garage, where working with the Tacoma company - he fits the full suite of upgrades to this type of cabinet (sold in the US by Harbor Freight): The full kit he fits includes: A quick change real glass kit A set of internal baffles which stop the build-up of media A set of better lamps (iridescent -so keeping the box dry) A better assembly method with lots of sealant and headless “rivet-screws” A relocated extractor position, a baffle box and a few covers that work with a vacuum flow meter and a simple adjustable valve for the shop vac pressure The removal of the ribbed floor plate and making the mesh grate smaller and lower to enlarge the volume inside. And then the gun setup: this includes a special funnel that replaces the trap door hatch, onto which a metering valve is fitted, plus a foot control and air regulator and a trigger-less gun. phew! Anyway, with all of the above fitted it ends up being quite a good machine - uses minimal media, which is fast to change and offers good visibility. so, onto me. I contacted the Tacoma company and - while their product seem excellent, the prices with shipping are a bit out of my reach. so, plan B: I can make the parts to do items 1-6 myself, with minimal effort, no worries there. Then we’re onto the gun setup (number 7 above). A quick google brought up an equivalent set (though inevitably cheap Chinese made) sold by sandblasters.co.uk for £159 So: £189 for the cabinet, £159 for the metering valve/gun/pedal setup and a bit of time and effort to fold-up the internal baffles and shrouds, change the lights, mod the glass and vacuum system coupled with better assembly techniques and I’ll have a setup very similar to the Tacoma company setup. But, it doesn’t stop there. I’ll be fitting a dust-buddy type cyclone extractor to a sealed bucket before the vac for about £18, like this: then - I revisit the gun... and my questions start: 1) would it be best, given my small setup to stick with the suction setup above or instead move to useing an eBay pressure pot like this? Obviously, I’d be binning the standard valve and would use the 3mm tungsten nozzle shovelled into the pipe with a jubilee clamp. 2) if so, is it best to go for 10litres or 20? 3) if I do go for a pot, and wish to keep the foot pedal - is that possible. 4) again if I go for the pot, where would the metering valve come in? Does it go on the bottom of the pot - and if so, is it a case of letting the media build up into the cabinet and emptying it regularly or is there a way of recirculating it? 5) again with the pot, is the t-shaped off the shelf metering valve still a good idea, or would I be better following brightspark’s lovely clemco-copy flat-valve? (I do have a small lathe and can cast aluminium too). ... so, a million questions - but hopefully should see the best home blast cabinet I can for somewhere between £400 and £500 all done. I’d like to blast everything from rusty Land Rover steel parts, to delicate aluminium and brass. Id like to be able to change the media regularly from j-blast to glass bead. I will sieve the media, but am looking for a reliable little setup with a 3mm nozzle (think I’ll need to make an adaptor for the Sandblaster.co.uk gin if I’m not using the pot). Any tips are very welcome. When it’s done I’ll do another build thread like I did for my (old) compressor build. thank you for bearing with me!
