well.. the last piece of the puzzle is here. went and picked up the 18’ flat PJ trailer with 5200 lb axles and brakes on both. all LED lights. rub rails. 16” on center supports. powder coat. spare tire carrier.

I must have missed the blaster part? That or I need to rename my trailer build thread!

i see what you did there. and this is the only thing i have good pics of as the compressor and blast pot we’re delivered to a friend of mines shop and havent been able to/no reason to go down without a trailer to put it on.

tomorrow is the day though. should be able to unwrap and fire up the compressor. and see where everything is going.

it’s all here!

tiny little air operated pump. AODD

turned the compressor to have the controllers and air ends pointing towards the driver side. all the fluid drain and diesel fill as well.

125 gal leg tank for the water/rust inhibitor mix. all i need it some plumbing and to mount the air compressor to the deck.

hoping to have it mounted and possibly plumbed by next week. should be a fun machine to work. just hope the work is there! hahah

That's friggin Heavy Duty!

What sort of work do you anticipate?

Ya know, you could probably land a municipal contract removing graffiti!

Be cool to mount a side facing blast apparatus, fixed of course, then drive alongside a long line of hippy cars.

i honestly don’t know what to expect. i’m thinking it’s going to be mixed car restorations, industrial renovation and maybe some city/commercial work. don’t know.

and.. i could make a side facing hippy removal nozzle.

So you pieced together your setup right? Any specs on equipment etc?

yessir. i speculate i saved ~$6-7k over ordering it direct from dustless. and i think i ended up with a nicer trailer/more heady duty.

still need some parts, pieces and hardware. but it’s nearly there.

the compressor is a rotair 185. 185 CFM @ 100 psi.

blast pot is a DB500 with electric dead man switch. 200 lbs of media and 20 gal of water per fill.

125 gal leg tank

flojet 5 GPM AAOD water pump.

i’ll try and update and i have/remember specs

stlaser · « **Reply #9 on:** March 27, 2020, 10:16:51 PM »

Diesel compressor

Can someone save me a google search and add to the thread of course

What does dustless blasting do? Why?

I’m sure op can add to this but it doesn’t heat up steel (think thin body panels when blasting) like regular blasting can do which can warp or wave them. Out here it is the preferred method for hot rod guys but expensive. I was actually contemplating a portable rig like this about 6 mo this ago but had not considered building the unit.

swbhobie16 · « **Reply #12 on:** March 28, 2020, 08:01:10 AM »

correct. also.. you paint with a much wider brush. it’s a 2” or so wide swath you can clean at one time as opposed to 1/2” or so that a sand blaster does. you have a lot of control with pressure and media usage to go from surface to surface. can do fiberglass boat hulls all the way to heavy truck frames. as soon as i get it operational i’m going to play around with it and see what all it can do. i’m very excited about starting this. not only for personal use with car restoration but as a viable business for 8 or so months a year.

fitting from the tank reduced down to 1/2” for the AAOD pump

took about 1 day for me to take apart a perfectly good machine worth about as much as my powerstroke. hahah

since i’m not using it as a mobile (pot) i’m just sort of hard lining everything (not quick connect fittings)

water/rust inhibitor in. valves to fill the tank/supply the hose for cleaning the work once done

bolted it down with stainless hardware. bc.. why else? hahah

swbhobie16 · « **Reply #16 on:** April 04, 2020, 09:09:07 AM »

compressor brackets bolted on.

the 2 side by side bolts go through another piece of 1/4” flat bar as a washer that lips into the C channel supports under the trailer. i didn’t want to try and hit the C channel exact with the bolts since it’s 1” wide and i used 7/16” hardware. so i just made it pinch.

hannay hose reel with 100’ of 3/8” line for rinsing work after its blasted

air outlets. the bottom/rear one is going to solely be used for the blast pot.
the top/front one will be used to run all the other air stuff. water pump. utility air line. breather tank/filter system for the blast hood. etc.

blast pot air line plumbed.

and water pump/blast pot feed/rinse line plumbed.

stlaser · « **Reply #20 on:** April 05, 2020, 08:00:57 PM »

Specifics on air line and clamps? Assuming internals are just barbed fittings?

swbhobie16 · « **Reply #21 on:** April 05, 2020, 08:50:09 PM »

1 1/4” 300psi rated airline
clamps are bolt style that fully wrap under itself. (think intercooler clamp)
fittings are just really large barb fittings.

compressor will run at ~125 psi when fully ‘charged’ and try to maintain that as air is discharged via blast hose. the blast pot has an incoming regulator to slow down or speed up air depending on surface being cleaned. i’ll try and explain alittle more when i have some time and can copy info from manual

the compressor should operate at 185cfm @ 100psi if i read the specs correctly. it’s roughly 3 cubic ft of air.. which is about 22 gal per second.. if i did my conversion right.

stlaser · « **Reply #22 on:** April 05, 2020, 08:58:04 PM »

Who did you purchase hose and clamps from? Was hoping online source, I’d like to connect my three air tanks for shop compressors and then feed them into a home brew copper pipe air moisture setup before going out into shop lines.

swbhobie16 · « **Reply #23 on:** April 06, 2020, 09:04:23 AM »

ohh. gotcha. sorry. they were sourced locally from a southern stated affiliate. i’m more than happy to package and ship whatever you’d need if you wanted to go that route though.

swbhobie16 · « **Reply #25 on:** April 06, 2020, 02:02:24 PM »

3/4, 1, 1 1/4, 1 1/2. maybe 2? i’ll check next time i’m there.

got it all plumbed up so it can work next week.

only pic missing is the small hose from regulator to water pump. will grab one in a bit

ever important tongue lock

stlaser · « **Reply #30 on:** April 12, 2020, 10:57:28 AM »

I have that tongue lock it’s ok, mines been beat on a little and held up. They weren’t very motivated, make the chains remove able, I've seen them use those to drag a trailer off. My trailer I’m building will have both chains and tongue removable.

locks are only intended for honest ppl. and i’m hoping to very soon have it inside a building. but until then, this along with (i’ve been thinking) a concrete anchor around the axle would help too. it’s mostly going to be hooked to my truck. this is going to be for when we go out of town etc. but even then i’ll keep it locked to the truck (hopefully)

swbhobie16 · « **Reply #32 on:** April 12, 2020, 11:29:12 AM »

removable chains are a good idea too. for sure. if i was going out town for a long time, i could take the tongue off as well. 4 bolts and it’s free

stlaser · « **Reply #33 on:** April 18, 2020, 05:38:23 AM »

Ok, so you’ve got me thinking about this. Back when I managed the steel shop we had a product line we ran providing steel brake backing plates for Carlisle Group. For a simple explanation we provided the steel plates on a large brake pad contract and they molded the brake material onto it. So our job was to build & prep the plates for adhesion. We had a company north of the border build us a wet blast slurry machine. The down side was that it would literally eat itself to death. We used high manganese plate (armor) inside the cabinet to literally protect the steel cabinet from the slurry blast.

So what you’re doing is something similar, but not in a controlled environment so what are the consumables with your setup? Sorry, I know very little about this and am trying to pick it apart. On the same token the speed that it cleans things up interests me and wondering if someone couldn’t build a shop wet blast cabinet? A lot of your cost is being mobile.....

swbhobie16 · « **Reply #34 on:** April 18, 2020, 06:12:27 PM »

consumables are the glass and rust inhibitor.

i would imagine in a room or booth the dust would be almost too much to deal with. so the few thousand you saved making it stationary would be eaten up with dust collection/ventilation and control.

i know it out a hurting on those fenders. and in a hurry (granted.. i was trying to see how fast it could go..)

Nothing shady about using that sand in a blast cabinet.....
