Abrasive Blaster questions

[Dusty Britches]

I have a couple of old metal tulip chairs and glider bench that I want to remove the rust from. It is medium - heavy rust and the way the glider bench is made, I cannot get a power abrasive wheel / disc in to remove it. I wish I could just use Ospho, but I think the rust is too much for that.

So I was thinking of getting one of those presssurized abrasive blasters from Harbor Freight (#68994 in case you were wondering).

I've never used anything like this and I'm wondering if there is anything I need to know before I buy and use it. Honestly, I was hoping to find someone who had one that I could use rather than buying it.

I've read that you should not use play sand in the unit.

Any advice? Does anyone have one I can borrow or can anyone in the Bryan College Station area do this for me?

I'm interested in this as well.

Use a specialized blasting media to avoid expose to silica dust. Sand blasting takes a LOT of air, most people don’t have near enough compressor to stand up to the task. Pressure is not the problem here but volume is.
You should be able to find a blast and paint business in your area that will blast it for you for less that the cost of the blaster and the media. Example, I just had a 6’ x 12’ trailer with ramp blasted, primed and painted for $250. I have access to a blast pot and could’t have done it for this.

so, what do I look for in the yellow pages?

It will work fine. I bought one for a project where I used a portable compressor (gas powered) and a sack of media from Harbor Freight. My project was to roughen up cured concrete and expose the aggregate so that new concrete would bond to it. It did it's job with ease. You might look into a rental for such a small job though.

I own items 96972 and 93221. Under $20 bucks, I also have cabinet #42202. All work great.

from what I understand, TM, those are for small items, like parts and the nozzle has to be on the part you are blasting. I'm sure they work great by reading the customer reviews, but I think the metal chairs and bench are way too big for those.

Is this too far?

thanks, tx, but yes it is too far.

They are quite agressive and will do the job but refilling the blast material is the slow down. I strip down automobile rims and powder coat them and the hand unit with playground sand is ripping rust and scale.

Here's a tip: I buy the playsand at Home Depot. I run it thru a kitchen strained (screen). It works great at $3 a bag. Have you thought about renting, although for the $54 dollars and own it, you can't beat that.

Also, my sure the gun you buy has replaceable ceramic nozzle insert (orifice) or the sandblater will eat itself. Cheap one may not.
