Harbor Freight Specific

#1
I am thinking about sandblasting minis. I do not have a compressor or anything. Harbor Freight specific, what would I need to do the job? Lets here your thoughts on the individual pieces needed. In case anyone else is considering this.

You would need a hopper for the sand, protective gloves, goggles/mask and a very large air compressor to push a lot of air.

I have a sandblasting cabinet, but not big enough to put any frame in it.

You'll want a good sized compressor with good constant CFM so it will keep up.
Sandblasting knocks the hell out of your compressor, and theirs nothing worse than running out of air midway through a project and having to wait for the compressor to catch up. Also a good quality water separator to keep the moisture out of the line.

As far as the blaster itself, I like the pressure pot blaster. It seems easier on the compressor and takes less air than the gun+tube type.

Just my personal opinion.

I would think at least 7cfm on the compressor would do the trick. The pressure pot blaster is listed under sand blasting on the HF website. I'm pretty sure I saw it the other day when I was browsing the site.

Ya thats not a bad unit ,I have used one very similar.

The key to it all is to buy the biggest compressor that you can afford

My setup is around 10 scfm at 90 psi and it is barely enough , it will hold 60 psi while continualy running but is not effective for removing rust unless your running at the higher preasures.
I blast until it cuts in then wait, check my part then start again when it builds back up .

I use a 5-hp electric motor to power my twin cyl compressor.I have it set at 130 psi and use a 60 gallon tank. This is fine for small jobs but the compressor runs nearly continuously. I am thinking of getting a 3 cyl compressor with a 175 psi top end.I sandblast all of my bikes,except my ratbike.I had at one time made a frame out of pcv pipe to use outside and recycle my sand.Wrapped it in plastic sheeting and worked away!That year we got plenty of rain,so i built a permanent room to blast in.I also may buy some better sand than the play sand i currently use from Lowes.

I use the HF 110# pressurized blaster and a 5HP 60 gallon porter cable compressor. Here is what I have learned. When buying black beauty it has sizes marked on the bottom of the bag. make sure you DO NOT buy the larger size grains it just jams up the tank at the bottom or at the nozzle. I forget the grade I use but it is the middle box if you get the larger grit it keeps clogging. Also I have 3 plastic dessicant filters going into the blaster as water will also cause it to clog. My compressor cannot keep up with it and I can blast at least a minute or so continus then have to wait. It will go more but when compressor keeps running a lot it starts filling up the water filters and a lot of water vapor gets in the line. The pressure blaster valve on the bottom adjusts the amount of product to be mixed with the air. Its setting is critical. Once you get it right it is amazing how fast the rust and paint dissapears. Make sure the part has been cleanes as grease of anything soft will not get blasted off very well. For better results get a 80 gal two stage compressor and you will get almost constant use from it.

One other important item, get a painters paper suit with hood to wear and use a respirator under the blasting hood. the blasting dust and rust is not good in your lungs.

I get my black beauty at the masonry place here it town that sells bricks and block. Last time I bought any I got the mid size black beauty medai and paid like $9.96 for a 40lb. bag, way better price than tractor supply or any other place I have seen.

I am just looking for something I can do in the corner of my back yard that isnt too toxic. I dont care about the cost of soda. I just like the idea of it melting into the lawn. I wouldnt use it too much so I didnt want to spend a lot. I just want to make sure it works.

I agree, soda is the safest media that I know of. I don't think it can really handle powder coat though, if you ever want to remove powder.

And I wouldn't get a compressor from HF. They seem to switch the ones they sell all the time and you can find a good deal on a good one. Mine is just a little 4.3cfm Senco but it was only $163 too.

Soda really needs dry air and a anticlog type valve. Eastwood sells the valve to convert the HF type pressure blaster to a soda blaster although it would work as is as long as soda is fresh air is dry and you strain for clumps when loading the tank. You cant leave left over soda in the tank as it will absorb moisture and turn solid. It is great for removing paint I do not know about powder. Great for cleaning degreased blocks as well. No good for rust removal unless it is just surface rust.

I bought a sand blaster from harbor freight. I can't remember what its called but it is basic a grey bucket with a hose and nozzel. You dump the sand in the bucket, hook up your compressor and GO!! I buy the play sand at home-depot and screen it when dumping in the bucket. CHEAP and I do it in the back yard:laugh::laugh:
