Gravity feed spot blaster gun?

[440dakota]

Has anyone used a gravity feed spot blaster gun? I understand that i will have to be refilled alot but its cheap and i only need it to sand blast my frame for the show thats coming up soon.

What sand do i use for it? what best for the frame and wheels?

Im wanting to get the whole bike blasted this week so i can get it in some paint
Thank you

I think you would be disappointed with it for that application. If I where you, I would get a cheap siphon gun rig. Sears makes a nice one, harbor freight probably sells one. Remember to wear a mask when blasting! The sand is dangerous to your lungs. Look up silicosis.

I did a set of GM backing plates using one of those...it took awhile and I had to refill it a few times. I think Spacecoast is correct in telling you that a syphon (or even better pressure) setup would work better for doing a frame. I do think that the little gravity setup would work just fine though, but you will end up going through tons of material. I used the aluminum oxided for what I was doing but that involved rust removal+the guys at harbor freight recommended it but did say that the blaster tip life would be shortened.
Definitely use a dust mask at the minimum and maybe put down some plastic sheeting to allow reusing some of the media. Hope that long winded run on sentence is helpful in some way.

I have owned one of the small gravity feed guns, it went into the trash before the 1st refill. I have also found that using a good blast abrasive instead of sand is quicker, safer (silica is bad for the lungs), and produces a finished surface. What ever media you use be sure to use a good respirator and not just a paper mask if your doing more than a few small parts.

unless you have a huge compressor you best take it to a guy that has a blaster as it is cheaper and better.

I do now have a blast booth that I bought on sale for $160 that is good for smaller stuff and maybe just a frame but it will be tight.

you dont need to look all that far to find a guy with a good setup that for $20 will do all the parts you need

Put a coarse wire wheel on your angle grinder and you'll have it off in no time, less mess, less hassle, wear safety glasses. I have all of the above and prefer this method.

Wire brushes have their place but a Speed Blaster will remove paint and rust quicker and better than ANY wire brush. This is what I use and it's an excellent performer on small jobs. The only real issue is that it uses a LOT of air and a LOT of sand.

I push it with this 5 HP two stage

Besides that a wire brush has limited access to recesses and cavities where rust likes to hide. You can pick up speed blaster for around $60 or so. The compressor is a little more

I picked up a spot blaster awhile back and honestly it is garbage. Like it was said earlier I threw it out after the first use.

Redoing the kart wheels now and I was going to go out and buy a bigger blaster but then I found out there is a guy less then a mile from me who runs a small business just media blasting

Brought them over today and for $40 he is doing all 8 pieces (4 inners, 4 outers) best part is they will be ready tomorrow

Then your sand or air was wet because mine works great. That is IF the sand and air is dry. Why would you throw out a perfectly good spot blaster. You must like pissing money out the window

If you ran dry sand throught your blaster you would have them today and saved the $40.
Oh that's right you threw it in the trash.

it could be like the sand blaster i have it hates the white blasting sand .i got a bag of good nice clean sand at the suppler and it would not feed for nothing . gave away the sand and put the gun in a box and left it . later i got some junk tire weight sand and tried that and hot dam it eats that stuff up like mad , so the media you are using may not work in the blaster you have . try different ones , some of the cheep blasters are picky on what they will feed . the one i have is from Cummings tools and is the siphon kind

The spot blaster was from tractor supply, cost was a whole $8. I ran baking soda through it since is said right in the directions no sand or silica (spot blaster, not sand blaster) Since it was only $8 it was an experiment, I wasn't happy with results so I scrapped it as a loss.

That's just my rich boy ways huh? Pissing away a whole $8 :doah:

If I hadn't thrown it away I could of offered to send it to you for free but the shipping alone would likely cost over $8.

Brand new boxes of soda=dry. It simply was not giving me the results I wanted so I had a pro strip them and spent the $40 to get rims that looked brand new the next day.
