Try getting out twenty tons of spent abrasive out a man hole. Then you can tell me.

The bad part of tank liners is having to vaccum all the dust left over from the blasting everything has to be cleaned. from the I beams on the top of the tank to the floor. then cart that up a dyke.

Please report back how many pounds you do use if you get the job.

The supplier here said Coal slag should cut as good as course glass but it's cheaper he also said coal slag blends in with the gravel lot I will be blasting on where Garnet will leave red behind. Another guy who was buying garnet said one bag of garnet is equal to 3 bags of coal slag but also cost a lot more If I get the job I will let you know how many I use.

Todd, Which media do you use and recover. You realy just sift out the big junk and pour it in and it just runs smoothly? I have never seen this happen. The flow stops after just a few seconds and I have to jog the trigger or shake the pot to get anything. It would take me hours to do anything this way and cost more in the end. How can it work for everyone but me? What am I missing here.

We were quoted $5000 to sandblast, prime, and paint our 20 ton equipment trailer last winter. We didnt end up doing it!

If you dont know, tell them by the hour.

Figure out what's the most grit per hour you can use.
fuel per hour.
taxes... and so on.
know add what you want for profit.

include it all in to a package deal per hour.
when you tell them how much you can say it includes labor, materials and compressor run time.

you said $500? - say at $175 per hour your leaving your self at around 2 1/2 hours of blasting. (not including travel?)

this way you still make something, and the costomer gets a deal.

(personaly you guys out west don't get the rust like we do up north, that trailer looks great, add 70% more rust and ya got a salt walter rig.)

i use starblast...and a more stringent sifter than the metal chicken wire that is fixed to the funnel that came with the surface tek pot...i made a different style...works great.i will get pictures and put them in the recycling thread.

I haven't done enough blasting to know how much I use up in an hour. I will start out with putting one bag in and see how long it lasts that way I can tell. The rust isn't just surface rust it goes deep into the frame underneath I would say there might be half the thickness left under it when I get done. If it was worse I think it would be worthless. I was driving away when I snapped that picture from my window with my blackberry. Well see if I hear from him I'm sure he will call someone else and get a 2nd estimate. I should take the picture and email it to a few guys around town ask them how much they would charge. I'm sure glad I drove over there and looked at it because when he first described it to I was thinking of a much smaller boat trailer nothing this big. I was going to give him a $350 estimate over the phone. I don't mind driving around town to look at these.

I would agree with blastserv. I quoted a 38Ft gooseneck 2 car trailer the other day with heavy rust at $1450. But it had a solid steel deck that needed blasted.

Dyer · 10-22-2009, 07:06 AM

Don't give a fixed price, tell him between 700 and 1000, keep track of your hours from set up to clean up. (including blast time)

Then charge him accordenly but dont go over your highest set $.

You will make money and they will be happy.

I would charge around 800.
We just did a sander (sands the roads for winter) that fits in to a 8' long dumptruck

Used course glass, stripped the out side and underneth. $800.
2.5 hours
7 bags of grit.
1/8 tank diesel fuel
aprox 700 profit

Florida has winter road equipment?

Dyer · 10-22-2009, 07:22 AM

This is Northern Rust...

kell490 · 10-22-2009, 07:59 AM

Oh yeah that is rust I was kind of suprised the trailer had so much rust like it had been sitting in water with just the bottom. The steel was about 3/8 thick and about 1/4 of that was rust on the bottom. The guy hasn't called me yet and he was really pushing to get it done this Saturday. I'm going to call him today because I need to pick up the slag before the place isn't open Saturday. I bet he gets some cheap labor and gives them a couple of wire wheels to go at it. Here in the south west we have a lot of cheap labor just south of the border. These RV dealers are hurting real bad in this economy.

Dyer · 10-22-2009, 08:09 AM

You need to hire the labor and let them do it
make the money off them.
Ha Ha Just jokeing....

Seriously I wouldn't do it for under 750!
You have travel
set up and clean-up (even if its just equipment)
blasting time (wear & tear on hoses and equipment)
Fuel and mareial

Don't sell your self cheep. I did a few times and it sucks.
some people just want to know how much there saving if they do it them self.
thats the draw back to FREE Estimates.

BLASTPRO · 10-22-2009, 03:00 PM

He wants you real bad because you are doing it for nothing. I understand times are tough in places and work is scarce but whoring yourself out (ive been there) doesn't do any good. I would blast it using steel grit in my shop for maybe 800 (unseen is tough) using the grit I have almost no cost in the media since its cleaned and reused over and over. If I had a heavy media cost along with fuel vs my in shop rotory I would be much higher. I turn away enough work to keep a small guy busy once or twice a week. I have a hard time just getting my trucks started and onsite for anything less than 1000.00, small jobs will break you if your not smart about it. If we have 4 or 5 smaller items to blast we will accumulate them over a week or so then blast them all in a day or morning then back to the regular stuff. He wants you to put it in writing so that when you discover you will have almost 500 into cleaning it you cant back out, trust me been there done that! I really really try not the make the same mistake twice and im not looking to reinvent the wheel either, learn from others!

kell490 · 10-22-2009, 03:23 PM

Well I guess I'm not doing it I called him today and he told me, " were going to rent a blasting pot from sunbelt rental and use our shop compressor". They have a really big shop I think about 30 RV lifts and over 100 people working there. I told him the compressor he has is no way enough to run a 600# pot. I explained how mine is only a 210 cfm rotary screw which takes a 80hp motor to run it. He would need some really big 3 phase electric motors to run it. He agreed the air system they have was designed for air tools not blasting. I told him he probably need a compressor also from sunbelt, but I forgot to mention with no dryer it might clump. He asked me how much coal slag I thought I told him 1500lbs. I'm hoping when he prices it all out he calls me back. His boss was mad because he is paying a full time body shop guy who isn't busy and could do it. He said that guy only used a tiny pot like they sell at harbor freight had no idea what they were doing. He also asked me if he could rent my machine for 2 days for $300 I told him no because I don't trust his guy to run it correctly. Plus if they guy got hurt or somthing I might end up in trouble a blast from slag on the skin would do some real damage at full power.

rlaird · 10-22-2009, 03:27 PM

$1050.00

On stuff like that, If I'm not sure what its gonna take, I come out ok if I get 150.00 per hour. I figure it would take a full day less 2 15 min breaks and 30 min lunch.

so 150 x 7 = $1050.00

BLASTPRO · 10-22-2009, 05:54 PM

tell him you will call osha and report him when his employess are blasting without proper respiration equipment. id do it screw em.
