Default Harbor Freight sandblast cabinet heavily modify.

I needed a sandblast cabinet but did not want to spend a bunch of money. I still needed it to work well.

I did some research. The are many videos with mods out there. lots of helpful ones.
Someone sells a kit with the upgrades but that was to expensive for me but those upgrades are very good. I just rolled my own as many other have done.

I used just about a whole tube Polyurethane adhesive to seal the bottom.
You do not want to use silicone caulking if you are going to be powder coating.

I removed all the foam that came on it everywhere except the door and the top glass.

I bought glass a lowe’s 24” x 36” and will cut it into 3 pieces. Under $15 This will replace the plexiglass this gets all scratched up.

I used a roll 3M VHB Waterproof Foam Tape for all seams in the top.

I closed off the top back baffle. (that will now be the air in let.)

I added a side baffle. That will now be the vacuum outlet.

I added foam insulation between the bottom and the top.


I am adding DIY metering on the bottom. Made from PVC and black iron at the top.


I cut the bottom tray you put the parts on to allow more room in the cab.


I added Eastwood foot peddle and nozzle.

I bought replacement hose at lowes for the media hose as Eastwoods was too short.

I bought something similar to dust deputy for my shop vac on amazon.

I have a Harbor freight variable speed controller for the shop vac.
I added LED light.

As soon as I started using it my shop vac it stopped working. I took it apart and the switch was fine then I looked at the thermal overload was good to my surprise.

I found the issue. You can see here the wire for one of the windings was broken. I will fix this after work.
I am using a bucket Vac but the 5-gallon shop vac worked so much better.


Here is a tractor step I sandblasted and powder coated. It is shipping to a customer today.


The only thing I need to seal up is the door.
I need to add some flashing to the door bottom.
I don’t want it to get a direct spray.
