soda blasting

admin

I dont know to much about it. I am looking to weld on a old car frame (the whole thing) and I am interested in getting a soda blaster to blast it.Anybody know of a good manufacturer for soda blasting machines? How big of a compressor do I need?Is the soda blasting material safe enough to settle into the ground?

Reply:We rented a basic pot type sand blaster and rotary screw compressor (IE jack hammer compressor) to sand blast the various trucks, trailers and equipment at our shop. The rental place also had a fresh air hood and compressor we could rent (well worth the money! clean air to breath, no masks and the hood didn't fog like our standard one.)They also had sand in various grits. The coarse sand worked well on heavy rust and paint, like on our big trailer and dump body. The finer sand worked well on the flat bed body and some spots on the truck doors and panels. It takes longer but isn't as agressive.We just did ours in our parking lot at the shop. We laid down a few tarps to make sand clean up easier (boss wanted to keep the stone look and not have a beach when we were done. We didn't piss around tryinhg to reuse sand, not worth the ag factor and time. All we wanted was a fast easy way to collect up the waste sand..No government ever voluntarily reduces itself in size.

Reply:Soda is sodium bicarbonate, NaHCO3, which breaks down to NaOH and Co2 eventually, so lots of it aren't great for your soil unless you like desert terrain. If it washed into the storm drains, some government officials would probably try to fine you. I'm not kidding....Did you hear about the official 'Regulators' requiring the 7 year old girl to be licensed to sell lemonade in Oregon? The vendors around her stood up for her but...http://www.oregonlive.com/portland/i...nd_runs_i.htmlBTW, Soda is now used by dentists for blasting teeth.

Reply:Soda blasting is nasty stuff, no matter the PPE you use it gets into everything and sticks with you.  It is not something you would want to use on rusty metal, there are much better media to use.  Sand, shot, glass, hell even walnut will work much better.Have we all gone mad?
Reply:If you need to clean up really delicate parts or have zero residue when you're done, check out dry ice blasting equipment.  I used one for cleaning up low pressure die casting equipment.  CO2 pellets will remove mold release agents without any damage to the underlying metal surface.  The pellets evaporate so there's no blasting media left when you're done.  I imagine they'll work OK on paint or light rust.  Probably no good for heavy duty stripping.The pellets have to be used within a day, or they go up in smoke.  But the equipment is reasonable to rent(if you can get it) and the hazards are minimal.  The time you save in cleanup, plus the fact you don't need any kind of fresh air hood, might be worth the extra cost.  A regular clear faceshield and a pair of leather work gloves were a lot more comfortable to wear than all the gear you need for regular media blasting.There's also aluminum oxide media for use with regular blasting equipment, which does a better job of heavy rust removal than regular old sand....The local shop I've hired to clean up parts uses Aluminum oxide and some other ceramic blast media(other than sand)  It all works well, with less hazards than sand.  I think the aluminum oxide is better if you're re-using the media; it doesn't break down as fast.Benson's Mobile Welding - Dayton, OH metro area - AWS Certified Welding Inspector

Reply:for an old frame,i would go to northerntool.com and get the sand-blasting attachment for a pressure washer. the water is higher pressure and less messy than air blasting. it's aggreessive and will do a great job. the attachment sells for about 60 bucks.
