As a note... I did try to get some turbo sleves in order to avoid the extra work, but now than I'm finished it would take alot to get me to part with these.



The process is pretty straight forward, and was made much easier with a couple cutting discs, carbide bur, and greaseles cutting compound. From 180 grit I did the rest by hand. It took me roughly 10.5 hours of off-time to get that *almost* mirror-like finish. Becuase these are from my cermet coated housings, they have a few areas where I couldn't get all the cermet coating off. The cermet does polish, but there was no way I could get it as smooth as the sleve itself.

You got some dedication.



Was it hard to cut?

Mr. Midas

Thanks,

Cutting was the easiest part. It took about 2-4 minutes a cut with my dremel tool, being carefull to go slow and easy to avoid kick-back.

The reason for cutting where I did is simple. Separating the difusser half where the angled ramp piece meets the floor of the sleve makes it very easy to bend and break the separate diffuser pieces out while holding the sleve in a vice. There were even nice casting lines to follow. I made couple notches on the front edges just to make sure it would crack there and not damadge the ramp piece.(Probably old news for most of you. Someone else deserves the credit for coming up with the cutting technique a long time ago.)

The carbide bur(with plenty of lube) really made grinding down the remaining material a snap. After that I used a grinder and a 60 grit sanding cone, followed with the 80 and 160 cutting compound, and finally, went over it with some sanding discs.

I could have been satisfied with the simple tool-sanded finish I obtained then, but I had a leg injury which gave me a lot of extra time... My finger-tips are a little sore now from all that wet-sanding.
