well, I tried to polish the valve colves last weekend and it did not turn out well at all. I sanded the covers with a 220,400 grit using the 1/4 sheet hand sander. then I manually wetsanded using 600 grit. After that I used the spiral sewn with black emery, spiral with brown, the lose with white. the result is depressing since it is now where near mirror finish. Infact, it looks like unpolished billet material instead
how long do I have to spend on each wheel? how much pressure? I was using a 1/2 hp converted sander and I can only get in about 5-6 minutes before the motor heats up and lose power. If I need to get a new motor, any recommendations for a decent motor but not too much $$$. Thanks.
