Txakura Posted July 17, 2009 Share Posted July 17, 2009 I'm kind of leaning towards just buying the $99 item and the bag o' soda... I figure it's A) likely to work without a lot of screwing around won't rocket through my neighbors house when my home made threaded adapters tear out C) won't make 'cool' shrapnel holes in my shed D) won't kill me Link to comment Share on other sites More sharing options...

I'm not saying I would max the pressure, but I understand your wanting to be on the safe side. :cool: Link to comment Share on other sites More sharing options...

I'll have to check with him and see when he gets another CO2 tank that he is willing to part with. Link to comment Share on other sites More sharing options...

I think I need to look in to this. I'm looking into stripping the bed of my Brat. Would this be a good thing to try? I don't mind spending all day stripping it, as long as the blaster is up to it...

FlyB0y Posted July 17, 2009 Author Share Posted July 17, 2009 (edited) That's a great link, thanks 7.62 FMJ. I'm curious now to know how the HF blaster isn't a "dead man switch" for the media flow, I guess they must just have the knob to adjust it. Seems strange that they wouldn't just have an in-expensive squeeze handle like on the fire extinguisher that accomplishes the same thing (not releasing media & air flow with out someone actively holding the valve open, i.e. squeezing the fire extinguisher) I'm also curious how well my fire extinguisher's hose will hold up to the soda, good thing I can get hoses for free.

FlyB0y Posted July 20, 2009 Author Share Posted July 20, 2009 Ok, no pics yet, but I will have some up tomorrow, but I found something else to use that is cheap and seems to work as well as soda would ... kitty litter! Costs about $0.37 a lb, and although it's less consistent, it goes through the fire extinguisher blaster quite well and does a good job on loose paint and rust. zzz I'm using fresh step brand (doubt it matters) because it was $9.99 for 28 lbs at the local grocery outlet. Pics to follow. Link to comment Share on other sites More sharing options...

The Dude Abides Posted July 20, 2009 Share Posted July 20, 2009 woah how did you get a fire extinguisher to do paint stripping. Link to comment Share on other sites More sharing options...

LMAO , I got enough cats around here, I don't need to encourage them seriously how's it do on pitting and scale? will it flake the big pieces away and how well does it get into the crannies? slight OT - I was thinking this would make a nice aux tank to help settle out condensation in my air lines - set a little air pig off the compressor, plug my work line into that - just a big water trap and a little 'buffer' for the main tank Link to comment Share on other sites More sharing options...
FlyB0y Posted July 20, 2009 Author Share Posted July 20, 2009 (edited) woah how did you get a fire extinguisher to do paint stripping. It's really very simple. Fire extinguishers are designed to use dry chemical powders, and baking soda (also known as sodium bicarbonate) has become a very popular sand blasting media for those who want to avoid the normal hazards associated with sand, glass beads and other blasting media. Baking soda isn't commonly used anymore in fire extinguishers except for very specific applications, the more common ABC dry chem is Ammonium Phosphate based powder (which isn't good to breath). So in other words, if you look at the first page, I show a pic and have a list of the parts to make it easily pressurized by an air compressor. The kitty litter isn't ideal (it isn't a uniform size) but it is cheap and effective. It does have a tendency to plug up the valve about every other tank, and just like using fire extinguisher, starting and stopping isn't a good idea, as the interrupted flow can cause the valve to plug. I try to just put 3-4 cups of media in it at a time and just use a constant flow. Here's a pic: This is exactly the amount of "blasting" I was looking for. It takes the loose stuff and leaves the well-bonded paint, and the rust is just cleaned up enough for a good coat of POR 15. I think the soda like you would buy at HF will be more coarse, but for my purposes, the kitty litter is the ticket. I think after using it a few times over the pieces should be smaller and more uniform, and should work even better.

FlyB0y Posted July 20, 2009 Author Share Posted July 20, 2009 One more thing I realized blasting some more today, you gotta keep the tank up-right (pays to read the side of the extinguisher ) and magically the media comes out in a steady flow. I realized since my hose from the extinguisher was on the short side, I just needed to extend the length of the hose and keep the tank vertical instead of holding it at an angle to get the tip close to the work.
