Buzzy, can you run dry media in that too, Or is it just a wet system.
Give some stats on the rig...
Water tank gallons?
How long you can run on a tank off water..etc

Most videos I've seen by them, I can get almost the same with my WIN nozzle.
I did see one page 250 lbs per hour on their web page. That's 5 - 50 lb bags per hour...

Worst job with my win nozzle and fine glass media is 4 bags per hour
But normally I can get 3 bags dry or wet..per hour.

I do like the wet systems thou.



Buzzy, it look like a really nice set up, clean! Customers like that when you hit there jobs!
( I've had guys use a few different blasters, and when you pull in with everything on a trailer .. There like dam, your ready to go.. Very professional!)
:clap::thumbsup:
It's basically a universal pot. You can use glass, sand, shells, etc... all relative to what you are blasting of course. It will work dry or wet. Sounds right on the amount of media usage. It uses an adjustable spider type feeder. You can adjust what comes out by adjusting a lever. With that said, adjusting pressure and media flow could increase or decrease usage. Wish me luck. Still 34 degrees here. Supposed to be up around 50 tomorrow. I will try some blasting then.

I've just finished building a water injection add on for my mmlj pot. Runs off the elec deadman. Can pump from 1 litre to easily 3-4litres a minute. From around 200-400 psi depending on inlet drive air pressure. The set up on the clemco appears to be similar to what I set up. The air drive pump is where the cost is. There are really only 2 manufacturers that I found that can supply an air drive pump that doesn't chew cfm can pump at the flow rate required and psi required. And the biggest problem is the duty cycle in this application, it is high and will kill most pumps. Id also invest in a check valve on the inlet to the air abrasive stream. And some sort of orifice to reduce flow and increase pressure other wise you will flood the place and the pump will hammer itself to pieces. I also put a quick exhaust valve on the air supply to the pump so that it stops immediately once I let go of the deadman trigger.

How about a pic STR8.
Sounds interesting.

Here is frankenpot at the moment. I have a job this weekend and need to do some refinements to the packaging but I've given it some dry runs as it were and the control setup all works. Hopefully it will reduce the water consumption and then ill focus on the grit.

The only other thing I thought about doing is to
Use a psi water tank. And a 12v solenoid thats normally closed, for the water shut off.

Having a water tank that is pressurized (or just a bit more)
at the same psi as the blast pot.

This cuts out mechanical pumps .... And once the water tank is pressurized, it won't rob cfm like a pump.

Could use it for win nozzles to.,

What sort of pump is that.
I'm interested in setting up the same sort of thing.

just a couple "cents"

If I could add any opinion, I would say stay DRY with the option to go WET as needed...I have had two of MMLJ's "Dry" units that I could easily covert to their "Wet" system, but to be honest, with what is involved when you go wet, I am not prepared to drain every job to make sure your system is clean and ready for the next. I have yet to see any of their lit explain what to do if you dont need a full pot for a job. Where and how do you dispose of your 1-2 gallons of your "wet" media? I just think it makes more sense to have the option "to" use water verses "not"! A WIN Nozzel will pretty much do what their wet system will do will more flexiability, if i am not mistaken, please correct me if I am wrong......Feel free to crawl underneath anything you need to blast from a boat to a car to whatever..do it wet? do it dry? you be the judge.I prefer to be dry myself.....

precisely why i bought the mmlj. the rigging is already done. as far as the water and media, shouldn't be a problem to let it sit in the pot until the next job. hopefully i'll be so busy the pot will be constantly ready for a refil.

Not trying to hi jack the thread but I've had some issues "wet" blasting with my MMLJ set up....typically I run fine glass, 70-100 or fine crushed light bulbs in a powder form for my hot rod guys. Moved into a building for the winter and experimented with wet blasting. Fine stuff seemed to clog no matter how open the pot was at full 125 psi. Talked to several people who claim it "should work"!!! MMLJ recommends this order, 5 gallon of water to 50lb media and 6 oz of Hold Tight. Seems the media is worm holing in the bottom of the pot and water is mostly coming out. Saw the video of the 63 Impala that got blasted in an hour and was intrigued! Any advice?

You are not alone mate. I am about to take to this pot with a sledge hammer. I have my frankenstien water injection on and it helps heaps compared to the fist fulls of glass that was chugging out of it before. I'm in 40 degree celcius heat fighting with this thing and I have had almost enough. I cant go heavy glass cause I am doing thin alloy panelled truck. Any ideas on how to get the metering on these pots better are welcome.

Hi guys, I've been lurking here a while taking in the good advice, I'm considering buying a wet blaster.

Has anyone had
experience with the German Torbo machines?

Just got another email from MMJ I noticed on the video that they now put a message saying the WIN nozzle is only being used because it was available.
I wonder if they lurk on here.:whistling

There's a guy here in New Jersey who bought a MMLJ Dustless Blaster and I watched him at a marina having the same problem as you mentioned with the pot clogging up.

It took him 3 to 4 days to blast a 23' boat with his Dustless Blaster and he ended up leaving a huge mess behind when he was done with spent media and ablative paint all over the place.

With the GeoBlaster I would have used just 3 bags of 50lbs medium recycled glass and had that boat done in 3 hours.... and that would include putting down my ground plastic, taping the waterline, tenting and blasting the boat as well as clean-up and pressure washing.

Sorry but Dustless Blaster is giving us wet blasters a bad name. :mad:

I looked at those on their site quite awhile back. They look good but likely pretty expensive. Did you price one out?

As far as the overall conversation here, I agree with Geo, its apples and oranges. Having owned and used my Farrow and understanding how a true slurry blaster works I can't see how a modified dry system is ever going to do the same thing.

On the earlier posts regarding boats, my experience with the farrow shows its easy to back off the moisture to the point that by the time any water hits the ground its already evaporating, the farrow's water heater helps make that happen as well. Sure, the grit on the ground is damp and heavy but runoff is virtually nill and if its a reasonably warm day the grit dries out fast too if you can wait a bit before clean-up.

Being able to pop the hose off the bottom of the pot and quickly rinse it out is also a big plus.

to be honest i have not blasted enough to have any issues yet. have you contacted zach at mmlj? that would be my first advice. like i said, i don't yet have enough experience to help you.
