hey quick question how did you get the tps to pop off. mine seemed stuck or something.

It pulls straight off, there is no tab or anything to worry about breaking, it's just a square peg in a square hole. Mine was on there pretty good too. I just wedged a small flathead screwdriver between it and pryed with slow even pressure.

k, i didnt want to break it. i have mine about 1/2 way polished. looks good but im still not 100% happy with it.

Yeah, It's crazy time consuming, and there are a million little corners and ridges that are hard as hell to get to. I took the sanding wheel and grinded off a lot of unneccesary casting marks, it saved me some time, but not a whole lot.

And for my next trick, Brushed Aluminum!

:cool: gonna need shades to look at that thing in the sun. cant wait to get mine finished.

I think I'm getting a little carried away with polishing stuff. These are my water pump pulley and alternator pulley. Well, half of it anyway. I'll get to the other half later. The water pump pulley only took about half an hour. I cheated and bolted it to my bench grinder and just held different grades of sandpaper to it.:D

@DieselMiata...I see that you have a grinder connected to an air hose...how much psi or hp would I need to run one of those things?? or for example a paint spray gun?? Just asking because your work looks awesome and you've got me thinking of doing something about my engine bay.

The paint sprayer is easy, since you can let go and let the tank charge up, you're hardly using it. I painted a house with a 5 gallon tank and 1/2hp motor.

When using an air tool, you're usually using it for longer periods of time, draining the tank quickly. A small angle grinder emptied that same tank in roughly 15-30 seconds, depending on what the regulator is set at. After that it runs off the compressor motor and won't run anything without enough power to do much.

This is why it's probably a better idea to use a ten dollar angle grinder and thirty dollar bench grinders. Electricity FTW.

I have a 60 gal compressor at home that does the trick for small jobs, but for most of this work (read hours at a time) I used the air system at the power plant I work at that has a virtually never ending supply. For extended jobs at home, it's easier to use an electric drill with the nylon wheels. The bench grinder trick works great for pulleys/wheels but not much else.
