sand blaster advice for working on my 60 stepper

[smilts60]

I tried asking in paint and body no reply. But I bought this blaster kit http://www.ebay.com/itm/170693975294...84.m1439.l2649

got it and some fine black beauty blast sand. Problem Im havibng is it sprays for about 2 seconds then stops. I can let off of the trigger and re pull it and get another 2 seconds over and over but it wont keep a continuous spray. Ive tried the putting the pickup tube in the top of a bucket, and near the bottom sideways.

whats the number of the sand?? sounds like the sands too big . ive used a #4 blasting sand it real fine .. where i work we rent sandblaster that can run black beauty thur it but the tip is like 3/8 and the pot is a 300 pound
with an 185 cfm compresser .. ive used some thing like this with # 4 silican sand not sure of spelling .. hope this helps

also another problem can be humidity it will cause the sand to clump to gether .. or not enough air pressure .. hope it works out

Im starting to think along the lines of the sand not being fine enough. A little thinking has me believing that it starts fine then bigger pieces hit it and it clogs, I get off of the trigger and it clears rinse and repeat. Ill try finer sand. Thnx guys.

Do you ahve a drier in line? Dry air is real important with a sandblaster I run 2 one at my compressor and one before it goes into my sandblaster. I also drain my compressor before I start. You can buy driers at HF.

Thats something I hadnt considered but i did feel a slight amount of moisture from the air nozzle.
