some thoughts

[" Jim McMullan" <macthehammer@xxxx>]

Hi All .Its a rainy afternoon. So decided to make some comments.To the guy 
that wanted to put one soft break shoe and one hard shoe in each wheel .Bad 
idea. you will wind up with 1/2 the low speed(soft shoe )breaking and ditto the 
high speed. Also although the pressure is the same on both shoes the forces are 
deferent due to friction defrence.Its not smart to put unequal forces inside a 
rotating mass.Whell bearing failure or worse spindle failure will occur in 
time.Thats why we Maguflux the spindles on rebuild! NEXT -when I took machine 
shop in high school in 1954 I was thought that the only thing to clean a 
freshly bored cylinder with was HOT soapy water.Casoline- 
lacquer thinner etc. will not work.You need the viscidly of the watter to 
float the( fines) out of the pores of the metal and the heat to expand the 
pores.If you skip this step when the rings burnish the cylinder you get a 
vary hard glaze which retards heat transfer and also prevents oil retention on 
the cyl. wall .The same thing would apply to break drums or cast rotters. Except 
for the oil part.NEXT To the guy with the banging rebuilt 
torqueflight The specs for a letter car on clutch pack clearance are different 
than a stocker about .010 less.if I remember right.When I rebuilt mine in 1978 I 
got the spec from a guy in Washington after many phone calls.Its written down 
some ware but I'm not near my books.Is there some help out there? Also 
remember that a torqeflite has to be run in.About 300 miles to get all the 
fuzzys off the fibers and polish the steels.At 1000 miles change the fluid 
to flush the little stuff out! NEXT the reason they

don't arc break shoes anymore is OSHA did not like the dust in the 
air.And break shops could not afford to make them dust proofed --Got 
side tracked to be continued. Jim
