[AT] Sandblasting

[James Peck]

This Eastwood model does have a nozzle deadman.

They are recommending ground glass as the abrasive of choice.
I used to use 3/32 inch ID nozzles with a 4 HP compressor. This one has metric nozzles. 2MM is a little smaller.

 [James Peck] This commercial model mentions that OSHA requires a deadman type arrangement to stop blasting if the operator loses control. That explains why the low end has been abandoned to the imports that do not meet the standard.

This link shows a slightly higher pressure in the tank than in the air going past the tee in the bottoms.

Compare this US made blaster to the 40 pound Harbor Freight model. The Texas blaster uses a Wye rather than a Tee to merge the air stream to the sand bearing stream. See the photo of the bottom.

The sand blaster I bought from a local welding supply place 40 plus years ago did not have any label or manufacturer info on it. I believe it did have an ASME pressure vessel stamp.

I used to wish that I had bought the blaster from TIP as they seemed to offer a lot of sandblasting knowledge. TIP has renamed themselves and scaled back their small blaster offerings. Harbor Freight may now dominate the small blaster market.

I wonder if Chinese imports have taken over the small abrasive blaster market. I wonder if any of them have a pressure vessel stamp?
