I have one exactly like the one in the OP's post. Before I began I set about getting a proper cyclone system set up and a filter to dry the air, I also made the modifications to the grit pickup pipe. This took me a good deal of time and cost me as much as the cabinet itself. It works just fine, though the compressor really isn't up to the job. Saves me hours of faffing about though going back and forth getting someone to blast for me. It also allows me to be a bit more targeted with my blasting and prep. It is something I wouldn't do without.

Any use?
Bench top blast cabinet mods
Hi all, A few months ago, I wrote here: https://www.mig-welding.co.uk/forum/threads/christmas-present.88530/ about the blast cabinet that my son bought me for Christmas and in it mentioned that the rather shallow hopper causing problems. Well, I finally got round to doing something about it...

Consider making your own cabinet. I needed something big enough to take a bike swingarm so I built mine into a set of Dexion type shelving with a sheet of glass for the top. MDF for the front/back/sides. Gloves and retaining rings easily found on E-bay. I've sold my pressure pot now but at one time I had 2 (1 for Garnet, 1 for Bead). Extraction is by shop vacuum in the side and I put an LED bar in there for the light. Apologies for the old picture as the setup is buried at the moment but it's in the back left corner here:-
I thought I'd make one . . . but the cost of the ebay floor standing one convinced me - by the time I'd bought materials, put it together etc . ..
So assembled with sealant, with extensions to the legs so I didn't have to stoop to see through the window, and it works pretty well. A well applied boot to the leg occasionally to shake the media up, regular sieving of it to take the large lumps of crap out, a big fan blowing into it, and a cyclone on the discharge side and duct to the outside, and it does what I need it to.

I took delivery of some glass media the other week....
How much are you guys adding to your little cabinets?
25Kg is too much I think....
Also have a vacuum cleaner attached to the exhaust of the cabinet....I think theres too much suction, cant open the lid and the gloves get sucked into the cab making it difficult to manoeuver to the blast gun...The filter lasted all of an hour! before become bound up with dust....I've taken it off now and just allow the crap into the vac.
Thoughts please on these points....

Vacuum cleaners are usually universal motors so should work with a basic speed controller, will be much quieter too.

You need a big filter for a vacuum cleaner and airflow across the cabinet with traps to stop larger media escaping. A K&N works well.

Bigger than the small paper filter most are fitted with or you end up with vacuum in the cabinet instead of a flow of air through.

I have had an Earlex vacuum on both my cabinets over 20 years and swap it between them. A while back I added a small pair of cyclone filters to each cabinet to catch and separate the media. On the Earlex vacuum outlet I have a Hoover bag to reduce dust, the plan was to duct that outside into a box.

just graft a 4inch cheap fan on to the end of the hose. job done oh and fit a rubber mat on the mesh in tank leaving about an inch all round for the grit to drop back down . it stops all the crap and grit been blown back up from the gun it use then you cant see a bloody thing its all cheap and cheerfull but very functional . another mod i did was extend the hopper and make sides for it so that all grit drops down in the middle
