Sandblaster Review

[Canuck]

Rob

First a appology for the poor sketch.

The filter is nothing more than a piece of EMT conduit that I had kicking around the shop.  One end is flattened with a vice.  A bunch of holes drilled through the sides, I think mine are about 3/8".

On my blaster it is pressed into a pipe nipple going into the bottom of the tank just above the brass ball valve.  On the pictures of your tank it would go above the reducer fitting you installed in the bottom of your tank, projecting up into the tank.

Seems to help prevent clogs in the sand coming out of the tank.

Can't take credit for the idea, copied it from a large pressure tank sold here in Canada by Princess Auto (our Harbour Freight equivalent).  Their's was made from a piece of plastic pipe fashioned in the same manner.

Hope this is some help.

Hey gang, Decided to make a new version of my old blaster to use in the cabinet I have that was a gravity feed POS..

Here is the link with all the pictures..

Its about 3 pages long, But details everything that happened so far..

I found out that pressurizing the sand only to say 5-psi helps with the clogging factor when your using a smaller nozzle, Also fabbed a way to use a foot-pedal as mine was made for a cabinet, It easily removes from the cabinet and to the great-outdoors of the back yard too...

This is the new design on paper..


and here it is almost completed... (Tomorrow is the TEST RUN)

I wanted to note that the hose is from a JUNK pressure washer and only has a 1/4" ID end to end, The ceramic tip is the original plugged with an alan screw in the side and a ball-valve added before it.. EASY !



Yeah It's an old compressor tank, Just didnt have the heart to throw it away.., Good thing huh??, Weld in a few bung's and GO...

Nothing was wasted, The original cast iron compressor head, plate and motor went on a JUNK Craftsman "dry running" 60-gallon unit that was TOAST due to burnt sleeves and pistons (NON oil head and the fan to cool it blows dirt on the sleeves? WHAT A BAD DESIGN THAT WAS)



Oh.. and how did yours come out since this post???

Enjoy

It works GREAT, But only for an hour or two and you blow a hose or valve from wear...

A friend in Illinois named Denny has used this NEW design (below)
in the past and said "it cant be beat"

So here is the drawing we made together online to share with the R.R.T.



And PROOF it WORKS !



Thanks to all my Chevy FOLLOWERS also..

To see what these are you would have to read 270 pages of the build diary...
