Well, I should have the engine/trans in the car by now, but this UIM has me bogged down. However, if I don't finish this now, I just don't see myself giving 2 ****s enough down the line to pull it off and finishing it. I can't begin to tell you how time consuming polishing these are! I'm about 1/2 way done, but getting the insides of the runners, where they are next to each other and down into the creases is going to SUCK!
If I had to do it all over again, I wouldn't have wasted my time and would have merely painted the damn thing. I have to keep reminding myself how great they look when polished to a mirror finish
Just for clarification, this wasn't a last minute decision to start polishing this UIM. I bought the thing in 2003 and promptly took a 60 grit sanding disk on an angle grinder to it. I removed roughly 80% of the casting texture with that back then. I then sent it to Extrude Hone when the original group buy was held for the "Max Hone" process. It's been sitting ever since. I really should have done this long ago and had it ready ... hindsight is always 20/20
Anyways, on to the pictures of the progress:
Note the lack of the casting "bumps" where the runners meet the main chambers ... this took a long time to do (did it back when I first got the UIM)
The "channels" between the joined runners need to be worked out due to heavy scoring by the head porting sanding rolls
very small pit marks are found here and there ... these still need to be worked out.
Ahhh ... finally ... starting to come together ...
Overview of tonight's progress.
