Polishing tight corners. New guy.

[chefboiali]

Hello all. My first post after doing many a searches so not to bother you with a drawn out question. Some of the picture links are broken in the threads explaining my question.

This is a picture of a vtec solenoid that I'm trying to polish. I've polished an alternator bracket before, but now I'm trying to do this guy. I have a rotory tool and discs, however, do I need to purchase the tiny, thin sanding attachment? The grit looks too hard. Also, since my rotory is adjustable, what rpm should I use when I polish the corners?

Any help would be great. This is a great forum. I'm grateful that it's here.

There are dremel bits called cratex that work very well. They are rubberized with grit in them. I don't know if HD carries them, I usually get them from machine shop suppliers.

Thank you kindly. I'll give it a shot.

also for the final polish i would get some of the felt points. use them with regular compound. also they can be shaped to what ever you need with a little sand paper and patience.

This is what you're talking about, I figure. Instead of getting a variety, I'll get a number of cone shaped pieces. A medium grit would be sufficient? No more than 20,000 rpm? I suppose I'll feel it when I use it. There must be a bunch of Polishing Jedi Knights in here that can feel when the right pressure is being utilized.

And you are referring to these, correct?

Thanks again to you both for your help.

Looks like you have the tools. Now you just have to get the feel. Like most of us you'll have a few oops but hopefully not much worse.

Have you thought about trying to find a gunsmith and see if he will let you try his tumbler. Since this is a one time deal...it would save alot of time....

Hmmm... It's a vtec solenoid for a d16z6 Honda Vtec motor. It connects to the back of the intake manifold and it's operated by oil pressure. Do you think that it would cause problems? I purchased a new motor, and don't necessarily NEED this piece, so I thought that I'd practice on something difficult.

Thanks for the suggestion. I'm doing my best to be as self-sufficient as I can.

If you disassemble the part it shouldn't cause problems, but if you need the practice then have fun with it and try different things.
