[SEL] Replacing Babbitt in M/B caps

[Curt]

Rick,
Oh you are in for fun pouring the uppers without screwing up the lowers! 
How about this. Drill and tap 4 #8or #10 holes in the caps, 2 on each 
side at each end near where the radius of the cap meets the flanges of 
the cap. Set the cap in place with some amount of shim you like and 
tighten the flange nuts. Now screw in 4 brass #8 screws until they hit 
the crankshaft. Set the screws using a locking nut. Remove the caps. Now 
use a piece of TG&P of the same diameter as your crankshaft about an 
inch longer than the cap. The 4 screws form a cradle for the TG&P to 
rest in.  Dam with Babbittrite, soot the TG&P, heat everything good, and 
pour it full while upside down. Once cooled and apart you should have a 
perfectly formed babbitt insert. Drill your oil port, add the groove, 
chamfer the correct side for shaft rotation and you're good to go. Oh 
yeah, and remove the brass screws. Plug holes with caulk and paint. 
Sound reasonable?
