I looked at harbor frieght and the largest tank they have is about 11 gallons. I have a 2 HP compressor tied into the same system. So I am thinking of leaving the compressor mounted on the tank and by passing it for the new compressor and an add on tank. Anyone see a problem with that set up. I really need the bigger compressor for the blast cabinet.

Just wait for a good sale at HF or Lowes, or pick up a good used compressor. Blast cabinet can use a lot of air.

For a blasting cabinet, I'd not want to use anything less than a 60 gallon tank. And as said, don't get the tank welded, get new.

I have a Porter Cable cpfc2tv3525vp 20 gallon, 175 psi vertical tank that is good for about 5-6 minutes of bead blasting before I have to stop and let it recharge for ~5 minutes till it tops off again.

Thanks for the input. I just finished rebuilding the compressor pump and the electric motor is good. 11 CFM at 90 PSI is more than adequate to run the blaster. It is the unit for the job. Increasing the size of the tank does nothing to increase capacity. It just means longer waits between recharging.

At least I am dissauded from welding the tank although I do have a certified welder helping me with the cars.

I would have it checked out by a cert, welder (your freind maybe), but thats just me. I have a welding instructor in the family and he said its no big deal if done right. Anyone telling you not to and has not seen your tank first hand is talking out their A$$.

Just get an old 100 pound LP cylinder.

Just take an old water heater and wrap it good with duct tape and bury it, should be fine.

Find a big tank with a bad compressor, gotta be plenty around.

Dan,

So you are saying that the old copper 30 gallon hot water heater I took out of the old house is an ideal candidate. It would be a pretty good hole and given copper prices these days I might be better off scrapping it and using the money to buy a new compressor.

From the link:

Then the tank blew, luckily for me, out the bottom. I feel quite fortunate to have survived this. The injuries were: bad laceration on the back of the left hand, all four bones broken where the fingers attach to the hand. Left knee took a severe impact from tank spliitting and broke the tibia and femur. Amazingly, I never lost consciousness and felt a bad pain in the front of my neck. Ran my right hand over that area after seeing my left hand and was actually relieved to see no blood in that area. Apparently it blew my left hand into my throat. The docs pinned the four bones together in my hand, put a plate about 8" long on my tibia and ran 4 screws into my femur. The ol' timex took a liiken' and is still tickin', just broke the band pin when it hit my neck. The truly amazing part is my wife, son and his girlfriend and an older friend were in the garage when this happened, nothing happened to them outside of some ringing ears, but not a scratch. The fridge next to the compressor was a little worse for wear as evidenced in the pics. The little TV behind the compressor had the cabinet half torn off, but the picture tube was still intact. The 16' garage door got one roller knocked out of the track and about 12 sheetrock screws got the mud knocked off them. All in all, I feel lucky I survived it. I guess we all have angels watching over us. I'll let the pics tell the rest. After looking at the pics closer I think the strap the wheels were attached to saved me from more extensive injury as it contained a lot of expansion on the side facing me.







You can find new tanks here

Hi Dan. I have one that I think is 30 gal that is new that I took the pump/motor off of as a replacement for the same that failed on my 60 gal upright compressor. I was going to use the left over 30 gal tank as a vacuum sump for a vacuum table I hope to build, but that may be a while. Even then I still have another spare.

I would sell you my leftover tank for $100. Any idea how it might get from here in western CO to your place? Know anyone going that direction who might haul it. It still has the wheels and everything but the pump and motor. I bought it at Sears about 13 years ago and it has never been even pumped up. It is black. I'll try to take a picture later this morning and post it.

Fabio, Wow. I think that is the exception that proves the rule. That is a catastrophic failure and although your injuries were serious, I think you agree you were fortunate. Glad it wasn't worse.

I'm not pointing fingers at manufacturer or anybody, but did a pressure shut-off-sensor malfunction? I'm thinking that tank had to be way beyond its design pressure?

Jerry Feather

Dan, here is my tank. It is actually 33 gallon as shown by the picture of the pump shroud that I layed on top of it. The soft whitish stuff on the tank is not paint or anything like that, it is frost. The tank is outside and it is cold here.

Did this family memeber instructor tell you the time/effort and cost it will take to properly patch up a tank?
