Hi.

I am a sculptor. I have some cast iron sculptures heavily encrusted with ceramic shell investment mold. I was considering buying a sandblaster unit, but I have a small studio and I don't like the idea of dust in the air. I wondered if a high powered pressure washer would have the same affect of blasting off the investment. Ideas?



Answer
Not normally - and not without introducing some abrasive which will probably be as bad. Another option is bead blasting, but quite honestly given all the health and safety implications plus buying kit you may never use again it would be better to send them off to a specialist shot/sand blaster.

Pressure washer is stalling?

Pressure washer suddenly stopped. It will crank back up but stalls as soon as pump starts increasing pressure. Does the pump need lubricating, and how do I do that. It is a Troybilt brand.


Answer
Sounds like the engine is running lean. That will make it short on power. The most likely cause is a dirty carburetor. Remove it, take it apart, soak it in a quality parts cleaning solvent and put it back together with a rebuild kit. If you leave fuel in it for extended periods use a fuel stabilizer.
