Colleagues associated with Ford 10s routinely scrape bearings from one size to another close.
It is tedious to set up in a lathe, esp for small removal, and if lathe has no saddle attachment slots.Someone here some time ago reduced by clamping on a hardwwod plug in the chuck, boring half way, then clamping on a larger plug and finishing. Fit finally by scraping. However easy to lose alignmemt.which gives something else to check.
In the film no mention of a reamer for the solid bush. Reamers do not always manage very light cuts well.
I was amused some years ago at a swap meet. A guy with a very strong Pom accent was trying to explain to an enquirer what he was selling. "Baarring scraarper" I dont think the enquirer ever figured it out.
I have read that after run in the progressive build up of embeded dirt in soft white metal bearings often actually reduces the clearance measurably. The crank on my car was only worn about .001 at 100,000 which makes those heavy ugly filters questionable( Unless using Dynanator timing gear!!)
