Soda blasting

[88Lt1wagon]

Do you think they realize they're "ruining" that patina? http://www.powerblocktv.com/two-minu...th-baking-soda

I like the patina and new paint. Anything is better than rattle can gray primer. lol Wonder how big of a compressor you need to run that blaster.

I'm not sure, I haven't used any kind of blaster yet, but it looks pretty slick, and I'd think the soda would cost less than sand/glass/walnut shells.

well i just bought one just like one in video from HF and bought the valve set up that converts it to soda i have a 5gal compressor and was told it would work fine can even be operated on a little bit smaller one but i dont know about that. dont think i wouldd try it on a smaller one. i am foing to try it out one of these weekends on a set of old rallies. said can use playsand just make sure to dry it out good like put it on trap and spread out untill dry then run it thru sifter to get out big chunks of junk. that is what i am going to try first, the soda is 39.99 for a 50lb bag.

Lasher78,
DO NOT use play sand or any SAND for blasting. You will get silica in your lungs and silicosis CAN and WILL kill you. It is not safe. There are other products that can be used for blasting that are safer. Yes, people still use sand to blast but they have a full respirator with fresh air that completely isolates their lungs from the silica dust.

I doubt very much that a 5 gallon compressor will be enough to run a soda blaster unless the project is very very small. My 20 gallon will only allow me to run my pressure pot blaster about 1 minute before I need to stop and let it catch up. Most media blasters will require upwards of 10 - 15 cfm at 90 psi.

I use Black Diamond 80 grit from Tractor Supply Co. The 50# bag is only $9.

I will second the dangers of "sand" also Soda leaves a residue so it must be cleaned thoroughly before any paint is sprayed. I know a guy who does glass blasting and that is good but it does leave a nasty mess whereever you do it.

I have a HF blaster and also use the TS Black Diamond but only on the small stuff. I have a 5 gal compressor and it has to catch up alot. I have used two compressors one time in tandem to blast some frame parts and it worked well but I also had to stop and rest but not as often.

Good luck!

I've got a "home made" soda blaster. It's one of those $20 stick the tube in a bucket type blasters that I use with a big box of regualr baking soda. It works great for taking paint of slowly and gently, light debris, but no rust.
Yes, it does leave a coating that a quick water wash off will take care of, then you're done!
I've done some small jobs with silica sand a few years back....saving up for a blast cabinet(and real blast media). Or, a really good respirator. The thought of cancer again doesn't thrill me....

Since Baking Soda is a base, plain water will not neutralize it as well as a weak acid like vinegar. I read it somewhere, but have not tried the following tip. After soda blasting, rinse with water and then another rinse with 50/50 vinegar/water followed by a final water rinse. That should neutralize the base properties of any remaining soda residue. If you spray an etching primer on soda blasted metal without first completely neutralizing the soda, then the acid properties of the primer will be neutralized and the primer will not adhere properly.

so i guess the blaster was a waste of money, perfect. story of my life and this project. it will be returned tomro.

As I understand it correctly, you can wash it off with water, not rinse, but actually wash.
I've soda blasted, washed/dried and then powdercoated parts. Over a year ago with no problems. I think the biggest problem would be the little crevices clean, but no worrys so far.
DON'T SEND IT BACK!!!!

Did Trucks do a full build on this truck? It's apparently been a while since I've watched it, last I remember it was Stacy David not Kevin Tetz and I really wasn't sure it was still on.

[spacedebris]

Stacy David left the show several years ago. He had a problem with the sponsors/manufacturers crushing the trucks after completion. He now has his own show Gearz on Velocity. Trucks and the rest of the "power block" has gone downhill the last few years. Now they are more like infomercials than the old how to shows. Now they are 5 minutes of how to and 17 minutes of sponsor ads

I have a 100 lb. Eastwood media blaster. Would like to be able to try soda blasting, but the adapter kit is $140! That's more than I paid for the media plaster itself. It is on "sale" right now for $80, but that still seems like an awful lot for what looks like a couple of valves, fittings and hose. Anyone have a good alternative?

well the set up i just returned to Harbor Freight had a valve set up with hose that was only 19.99. it just screwed on to the bottom of blaster directly to tank. may look it up online and see if the fitting would work same on yours.

Yeah, that looks like it would work. Looks just like the Eastwood item and both say that they fit 3/8 or 1/2" outlet. Thanks!
