Sand Pot said:
I looked at those on their site quite awhile back. They look good but likely pretty expensive. Did you price one out?
I'm really leaning toward the Geo Gb400Sa now based on the discussion here.
I really like the new twin pot version on the website.
Maybe GoGeo could Pm me some info and pricing please?

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:
Could you post some video of you doing this type of blasting? I tried to research units before I bought the MMLJ. According to my findings, I purchased within my price range and or budget. Just wondering what a machine of that caliber (geo or farrow) actually looks like blasting at the psi necessary to do a boat bottom? I have and expect to learn a lot from you guys, but not having anything of the sort in my area to compare with is what lead me to MMLJ. So if you have some video, I am curious and would like to see one of these high dollar rigs go at it.

Either way thanks

2 and a half days 700 litres of water and wait for it....... 1.25 tons of fine glass. Or over 50 bags. with the current mods to "Paris" my high maintenance, never happy dustless pot I have halved the amounts of fills needed and almost halved the water usage. More mods to come. Next up finer water and sand control.....hopefully. Otherwise ebay for Paris it is.

I've talked to Benny and Rhonda....."it should work" was the initial answer....then I got "maybe 70-100 is to fine". I can tell you the unit will not blast outside when its below freezing. Moisture trap freezes up with and without the fan.....snow or ice clogs the lines....including the pinch valve which then leaves you with a constant running nozzle. Its a fair weather machine in a nutshell. I like how it performs but it needs to be above freezing and all the moons lined up perfectly. Besides moisture I've had loose wires to chase down....butt connectors.....ugh....how about soldering wires together??? Nothing like firing up the machine...getting all set up on a job and you got no juice. Waste more time with a test light and multi meter some days.

SD DMB that sounds like not much fun. I have not blasted enough to have trouble. I am fortunate to have a place I can blast out of the weather if truly needed. I am not doing this full time so I guess I am a fairweather blaster. In looking over my rig I don't see that much that looks suspect. Hope I don't inherit your troubles.

e+mc2

Ok guys I have an add on wet blast system that will work with almost any dry blast pot that is operating to your satisfaction.
First of all any of these systems that are showcased here are merely rearranging the energy that is input to them.They are expensive too.
The energy originates from the air pressure and volume that are delivered through the supply hose,temperature could add some energy but its effect is negligible.Basic layman's E=mc2.
Therefor pure wetblast systems might be more efficient and trouble free but they are just a means of delivering the energy input into the blast system to do the job of stripping the coating from the substrate.
A win nozzle,water ring or Clemco water injection all require a secondary water supply hose that is a pain in the butt to use and their water delivery is not steady or delivered in the exact amount amount needed.
So the answer to this problem is to inject water into the blast apparatus after the mixing valve at the right volume and pressure.Dyer was onto the right concept but his trial did not work.I am on a large dry blast project now and will post pictures of my system the next time it is used.It can be seen in action on my website- page one video -removing line stripes

Wess, I got your pm a while back
That's great you got it fine tuned to work! Awesome
I knew it would work, I just didn't have the time when I was messing with it or the money! Lol

I did know that balanced psi or just a bit more water psi would work!

I really want to see some pic or videos.

I'm not sure if my water injection systems as technical as yours Wess but it didn't cost excessive amounts in the end. Its air driven uses about 5cfm when running flat out. I have it barely cycling so if it uses 2 cfm up id be surprised. Another thing I have found with this mmlj pot is when you are blasting with water injection on the compressor has more room to go up in nozzle size. I'm running a 5 on it now with crushed fine glass. I think it could handle a 6. Maybe my compressor has more room to move?

Less cfm required

Yes the water in the line displaces air so you need less cfm, the only time a properly engineered system will not work is if the grit that is being used becomes soggy with the addition of water I.E. walnut shell or corn cob to name a few.

This is a pro-bono job I just did for a Catholic charity that was vandalized with hate graffiti.

http://youtu.be/KPnZR14P_Ms

The graffiti was on painted stucco and I removed it with my GeoBlaster with out damaging the stucco or removing any of the color.

I blasted it with very low pressure between 30 psi and 35 psi and then turned both the media and water way down.

The graffiti came of real quick and Our Lady of Mt. Carmel Society was real happy that it was gone.

Best of all there was no mess left behind.

The GeoBlaster is very clean and easy to use. :thumbsup:

nice. looks super. did you use fine glass on the stucco? i don't think i can go that low. probably about 50 psi. what does it look like turned up? thanks.

One other thing to think about is that both GeoBlaster and Farrow will give you the names and phone numbers of their customers who use the system so you can call them and hear directly how they like the system and how it preforms in real life.

MMLJ Dustless Blaster will not give you any names of their customers or users and there's a reason they don't as you can see from a few of their customers who have been using their product for a while and posted here.

Actually I get several calls a month from potential buyers that MMLJ refers to me. Right now might not be the best time to be calling me however with my recent issues! Alabama, Florida and Maine already this month have called me.

I have always said that those MMJ pots only shoot soda well.
They will shoot garnet great (but usage is high) anything else is hit and miss.
I'm waiting for them to post on here.

That is excessive usage for a no5.
I could blast that with less abrasive with a no7.
If you are having flow issues do you crack the ball valve on the moisture separator while blasting to let the water out.

Not true. Got a call last week to do a corvette. MMLJ referal. Trying to get together with them.

I did make a phone call to mmlj initially when I started out and the response was 11 minutes pot time is acceptable, he did say that the glass I was using is too fine so my production rate would suffer even more. I am going to blast today with some .85 crushed glass. I really do hope it works better. i am concerned that if i get a job on a car with the curremt issues that .85 will be too savage and the finer glass brings up a beautiful finish....until it chugs a fist size clump of glass at the panel, and it hits hard.
What is recomended to use other than fine glass?
