Just womdering what this recomendation is?

What grit paper you use to polish the bearings?
i'm curious about these two questions as well ...
thanks.
looks nice, man. good job.

Engine looks awesome.
Bearings are polished to slightly increase clearence, and to reduce friction in the oil as it flows through the bearing.

The logic Greg is that the bearings with creat less friction if they are polished. The oil will stay in place once the E shaft is in place. Call it suction if you will. Polish=smoother=less friction=better.

More polished=less surface adhesion=less oil on surface=early failure.
also
At startup there is no oil on a polished surface. You will slowly chew up your e-shaft and bearings at every startup. If you dont bealve me do the experiment I talked about.
Talk to some pistion engine builders on this. They dont do this unless the intent is to start the car once or twice before the next rebuild.

I'm still waiting for the pics on the "backcutting"...
But then again, I got blasted for that logic, so what do I know...

BDC, dont mean to flood you with more questions. What type of seals are you using apex and side. Anything special?

And also, man I wish my bridge turns out like that. I am starting it this Friday, so I hope I do a good job.

You can also look at this way. the more surface area there is, which causes more friction. ...it is not smooth, but very rough, but it has less surface area, so it has less friction.
Very nice pics, the more I look, the more I want to rebuild an engine.
