We have a scat blast cabinet at work. A bit pricy for home projects though. I found glass works ok but if your working on something with mill scale aluminum oxide cuts much faster. Though using the al you wear consumables out quick. Another tip keep a soft ball in cabinet hold it on nozzle to back flow the media when it starts cutting slow.

TP tools Skat Blast are going to be the most common decent quality blasting cabinets you'll find short of higher end industrial units. As above I generally keep 80 grit aluminum oxide in mine. Exhausting vacuum to outside is helpful.

Hopefully you have a decent air compressor first.....after that, you can get away with a harbor freight cabinet for most things

AmishBob is right Bill, the volume of air that you will need is considerable for a blast cabinet. If you are only doing this as a home hobby thing then get a harbor freight floor model but seal the joints on it. Trinco makes a nice unit and that is what a lot of guys use here but they are a lot more than a harbor freight unit. Scat Blast also makes a nice product but give me a call and I will walk you through some details that you need to consider.

I like my Trinco a lot better than the TP I had before
Air volume is the key to any blast cabinet!!!

I've had this Skat Blast cabinet for probably 25yrs. Not top of the line professional quality but decent. Raised it a bit for better working height, added a lot more lighting and a vibrator to help abrasive flow (but it still piles up). Agree on need for adequate air compressor. This one will outrun my 5hp/60gal Ingersoll Rand compressor after a few minutes so frequent breaks are needed if doing a lot of blasting.

I saw plans to make a sanblaster when I was 15. I finally made one out of plywood when I was 25. Ordered all the parts from skatblast. I'm retiring the wood one because ever since I moved to Arizona, it dried out, and media escapes from every seam. Rather than tear it apart and seal it, I picked up a used Trinco yesterday. Needs to be cleaned up and new glass.

Have a suggestion for longer parts. Used a carry bag for a folding chair. It works for longer parts like a 5 foot tongue from an M3A4 Hand Cart.

This sandblaster came from a business. Looks like they never emptied the vacuum recovery can. It was almost full to the top so the bag was laying on top of the sand. Employee probably complained and said it not working anymore. I guess I ended up with about $90 worth of media. So clean your vacuum system occasionally.

My 80 gallon two stage keeps up with the blaster. Sounds like a 60 gallon is to small but will work fine for smaller projects and show patients.

Craig, 1st. Your home built blast cabinet is awesome! It's great that you got so many years out of it!

2nd. How did you find your new one Ebay? Craigslist? FB Marketplace?

I want a blast cabinet.
Third question: How many CFM are typically suggested from a compressor for an average sized cabinet and blasting nozzle? 6.0? 8.0?
I've been watching Facebook and offer up for probably a year. Have missed a few nice ones and I glad I didn't buy the ones that needed lots of work. I was looking for bigger unit that could fit a 2'x3' Hand Cart body in but decided might be easier to take it to a local place that I have used. This size unit can fit 90% of most peoples needs. Tripod legs, shorter barrels. I need to modify it with the hole because my 50 barrel needs blasting on the outside.

Found this on offer up.

This Trinco is about $2400 new. I paid $800. I'm not much of a Hagler and I'm sure I could have got it cheaper but I'm happy to have it.

I will let others answer the technical stuff. I just kind of blast away and don't pay attention to the PSI and stuff like that. I have only used an 80 gallon 5 hp two stage. Have found it will run a lot but catches up if you don't keep the trigger pulled the whole time. Don't know if a 7.5 hp motor will help or not.

Gotcha! Thanks for the tips on where to look.

Can you post a pic of the label on the front of the machine so I can research that model?
Sandblast tips.

Keep a tray inside for small parts

Use electric fence wiring formed to a circle. For nuts and small parts with holes in them.

Keep a heavy metal object inside to lay stuff on while blasting.

I have a shoe shine brush or soft bristle brush inside to clean dust off the window.

Thank you and great advice! The shoe shine brush is clever. I've not seen that before but have done a lot of blasting and know that that is a GREAT idea!
Harbor freight's blast cabinet requires 9.5 cfm at 90 psi
I found a little metal mesh pencil holder (the tall cylindrical type) at some office supply store and screwed a simple wooden handle to it. Just put the small parts/bolts/nuts in there and blast into it, shaking occasionally. cleans small parts easily without losing them down in the media
