Is sandblasting this with this possible?

[wfochris]

This needed some TLC (engine was leaking oil and the fork seals are shot)

I love rebuilding these things and now I'm down to this:

I'd like to sandblast the frame and coat it with truck bed liner.

Will this suffice?

this compressor?

(The impact has no meaning, already had this pic- just see compressor in background )

Even if the setup isn't "ideal" - can I get through it you think? Never sandblasted anything in my life.

If you were closer to me we could bead blast that up in my cabinet. That compressor looks like an oil less one you might burn it up trying to keep up with that sand blaster.

 

[padronanniversary]

just do short bursts. you won;t be able to just blast full go, but let the compressor build up, then hit it for a few seconds, then let it recover

 

[dodge610]

Try padrons idea that should work after about 5 minutes you should let that compressor cool for about 10 minutes.

I have this kind of blaster (the 90lb version), I guess this one works quite in the same way but in smaller...
I blast motorcylcle's frames without problems, it's quick and neat, ready to paint!
Air consumption with pressurized blasters is really lower than in venturi type (such as in blast cabinets) but if you're compressor is oil-less, take your time!
Maybe you'll have some problems with moisture in your air, it will clog the air/sand mixer, it's really annoying, a good water separator would be a big plus! At least it was for me, the one I received with the blaster was useless...

Have fun, pressurized blaster are nice for this kind of job, but be ready to get sanded

 

[dodge610]

Buy the water separator they have at HF mine run about 20.00 to 25.00 that should work fine for your app. just drain it often to keep sand from clogging up. The Nozzle good luck with the sandblastimg.

 

[wfochris]

Thanks for the quick replies! The compressor is an oil unit. Probably going to give it a whirl.

 

[dodge610]

If its an oil unit you can probably go a little longer a trick you might want to try put a small fan to blow on the comp. while its running that will keep it cooler i have one on my big compressor that i turn on when i beadblast has worked for me.

do it on a tarp. reclaim your media with a shopvac and reuse it.

 

[pirana]

I'm sure you already know, but don't forget to plug where any bearings go.

I bought the same set up 4 or so years ago. For what I need it for it was a good buy. Getting everything adjusted may be the most frustrating thing for you. Patience Grasshopper.

Buy the 40 dollar(32 after coupon) desiccant dryer from HF. I hooked mine up temporarly for now with a hose from the compressor to the dryer until I can buy some black pipe and plumb everything right. I haven't had any troubles with moisture in the lines. Plus the desiccant beads are reusable.

Clean and dry air is key when blasting.

 

[Steve_P]

not to burst your bubble, but blasters use a LOT of air. You need ~15 CFM to feed one and I doubt you have more than 7 with that compressor. I had a 10-11 CFM "5 hp" (probably 3 real hp) compressor and it would not keep up with a pressure blaster. You can blast for a minute and then wait 5 for the air to build up. Put a fan blowing on the pump and if you're not in a rush you can probably get by.

 

[tyndall]

It'll work. You'll just have to wait for the pressure. I run one off a 7cfm compressor. As others have said, get a drier. With the compressor running all the time you will be making a lot of water which is going to constantly plug up the nozzle.

Considering what it costs to have a frame blasted & powdercoated, trying to do it at home is basically an exercise in futility ....

 

[Kev442]

I really depends on whether your compressor is shutting off at 125psi or 150-175psi. The blaster is set up for 90 psi and as soon as the compressor drops below 90 you will have to wait. 125 to 90 happens pretty fast.

 

[wfochris]

What would you guess the cost to be ZRX?

The frame paint they use on bikes is pretty strong stuff. Your blaster will probably not take it off with that air compressor.

In fact, I was just blasting an ATV frame last week. I have a 110# HF pressure pot, and an 80 gallon 2 stage compressor 12.6 CFM @ 90psi. Was using play sand.

It would have taken forever to get all the paint off with that setup. I ended up burning through almost all the pot and was just able to hit the real dirty/rusty spots and get them clean. That was good enough to paint it. It's not gonna be in any shows, etc..

Your compressor is probably about half the CFM of mine - So I really wouldn't expect much from it.. It might blast off some loose paint, but don't expect anything great from it. Like said, it might be easier/cheaper to pay someone to do it if you're looking for a good job.

The water separator that comes with the pot works fine. I've never used any other water separator/dessicant with it and have never had a problem.

I do it for 100.00 all the time usually have the color you want it to be in stock most of the ones ive done have been black,red,or silver just to give you an idea.

Dodge- Had this not come through, I would have shipped the thing to you!

My aunt's husband has a huge blast cabinet where he works. Made quick work of the frame.

First coat of rubberized undercoating is on:

Thanks for all of the advice!

 

[EricR.W.]

Chris, have you ever heard of that chassis saver paint?

Its a brush on paint that looks surprisingly good and is very durable. This stuff can even coat over "cleaned up" rust.

I just thought I would mention it since it seems like you were looking for a durable coating.
