The more the air flow , the larger the air compressor you will need

i never understood why people with the crappy harbor freight gun, wouldn't just buy a good gun? it makes all those mods un necessary and probably uses less air

You’re using too small of a tip. Use a larger diameter tip

Its so simple how could you miss it? Think of your gun like a garden hose nozzle. Pretend you are cleaning the sidewalk with the hose. What will do more cleaning? A tiny nozzle or a larger one! Obviously your bottleneck is the NOZZLE size. You will also need to balance the size with the amount of CFM produced along with the delivery mechanism the hose size. Increase the nozzle, increase the hose size, make sure you have enough CFM and that can be easily accomplished by adding reserved air tanks inline with your compressor. In my situation I have 4 reconditioned 100lb used propane tanks connected upside down in series with my air supply. Plenty of air and super fast blasting.

Before you're going to be able to get much use out of this, You'll have to make sure that your compressor is capable of producing the volume necessary to be worthwhile.... Just saying...

whats the LPM on your compressor?

Another useful mod is attaching an earth wire to the gun. I did this because I kept getting static electric shocks through the gloves.

I have a cabinet and the sand gets stuck when it gets to the gun. It’s the original gun and black diamond media there is no moisture either I’m stumped any help

That particular gun that you have is one of a couple that Harbor Freight ships with these cabinets. That specific gun is nearly identical to TP Tools (Scat Blast) S-35 Series cabinet guns. The only part that I know will not precisely interchange is the power head assembly which, if you have access to a lathe, can be bored out over so slightly to fit the body of the HF gun. The reason I mention this is that TP Tools offers all sorts of nozzles and gaskets that work well and offer a choice of options with these cabinets. I am NOT associated with TP Tools in anyway, I have just found that HF is awkward to obtain parts and accessories from - that used not to be so. Back about 15 years ago HF had an excellent parts dept. Don't know what happened, but the last couple of times I felt ripped off and delivery was dreadfully slow.

Ok, so I did a number of upgrades to my own cabinet. Including a modified pickup tube and I made the air hose larger. Even after a 3/8 adapter, larger air hose, bigger pickup tube and hose, and all of my other modifications, the cabinet still worked OK.

I have seen recently someone added a larger ceramic tip and got a considerable difference as well,

On the stock cabinet with stock trigger and feed tube, I drilled 1/8th holes, an inch and a half from bottom then 2 inches from that hole thru one side of exterior and interior feed tube then covered exterior tube with heavy duty ducting tape twice. Small piece then a larger piece. Then 1 hole at the fed tube were it connected to the hose and it made a huge difference. I do have high flow on the compressor and hose because I used it for the mail guns.

Great tips. I'm glad I tuned in and watched your progress.

Nice job Chris. Good improvements excellent camera work with good lighting.

thanks for taking the time

Awsome video man. I have the bench top blaster and it leaves a lot to be desired. Ive been thinking about buying that cabinet but was worried it would be just as much of a let down. Thanks for the tips, going to use all that info and build it just like yours

i've used those Milton Hi-Flow fittings for years now and they're amazing. Try putting them on die grinders, impact wrenches, etc and you'll see a huge performance improvement.

Wow, very impressed. Thanks for the video !

Terrific video. I subscribed with enthusiasm. I love experimenters.
