I took a 312 crank into the local crankshop to see about having it machined for a 292 block.  Everything was going well until we came to the oil seal area.  He said he didnt have a stone small enough to take it down without removing the slinger.  Same story when he checked with a bigger shop in Eugene.  He thought it would not present any problem removing the slinger since most or all of the later model Fords didnt have them.

What will be the end result if it comes off?

I could probably have him do everything but leave the slinger and oil seal alone.  Then take it to a machine shop with lathe and they could take it down.  However, will the removal by a cutting tool give a good enough surface?
