SandBlasting

Anonymous-0 · Mar 1, 2009

Perhaps this should be in a different forum but this one seems the most used.

I have a couple of JD 2510's I am working on and have need to do some sandblasting. What is the best way to get started and what is the best most healthy media?

Would the Texas Blaster be a good way to get started or a Clarke 20 gallon abrasive blaster? I like the TPtools blasing cabinets but they are a little more spendy, perhaps later. Also, what about media? For doing tractor sheet metal and castings what is the least toxic easiest to workwith media? Any comments/suggestions would be appreciated. Paul

What I do is spread some fresh wheel bearing grease on the outside of each seal, under the gear shift boot, and cover the grease and boots with duct tape. Then have the tractor sand blasted by a pro.
I have a harbor freight blasting cabinet for parts and it is much more convienient for cleaning off parts than the tank style blaster. I use "Black Beauty" media in it. It is more aggressive than sand. It will cut faster than sand on powder coatings. Supposed to not be toxic to your lungs like silica sand is. I have a 10 gallon size pressure tank blaster. Black Beauty doesn't work well in it because it does not flow as well as sand does.
Whatever you decide, you will need LOTS of compressor. The 10 gallon tank requires up to 25 cfm @ 125 psi. I have 2 80 gal 3hp compressors that are rated at 13 cfm @ 90psi. I can run the cabinet non stop and 1 compressor runs constant with the 2nd cycling. I haven't tried to do much with the tank blaster.

I usually take all the big stuff (sheet metal, large castings) to a pro, and do the small stuff inside a small harbor freight blaster at home. The bigger compressor the better (plus some way of catching/sucking the dust out of the cabinet if working at home). I use aluminum oxide and it works pretty good. Doesn't always slide down the bottom of the unit real well, but that just tells me it is getting dirty/wet. If blasting outside with a pot make sure you have some type of mask on with a very fine filter. It won't stop everything, but it will reduce what you breathe in.

1 think I always forget, this old paint has lead and isn't the greatest to breathe.

Don"t use any more pressure than you need to get the job done. Sand blasting can stretch the metal (sheet metal) and it may not fit exactly right. Had this happen on a 49 MT. I don"t sand blast sheet metal. rw

Go to the body and paint forum and hit the archives. There is plenty in there both pro and con. Also , silica sand is not "toxic" in true meaning of the word. You can hold it in your bare hand all day and not die. You could put some on your toung and not get sick. It is the dust of the broken up silica that if breathed in in any appreciable amount will get into the lung sacs and since it is still basically microscopic glass slivers , will cut what you don't want cut. A hood with supplied clean air piped in is the best protection .
