Recent discussions on this list have dealt with drilling pinblocks, the 
problems of heat glazing, etc. Various factors such as drill size, drilling 
technique, and the type of block have significant effects on the initial 
torque reading of pins in a new block.  If you drill and test, and the torque 
is wrong, you adjust to get the result you want.  A new pin installed with a 
particular technique, like a driving lube, can drop or raise in torque value 
over the first week. Do you allow for that?

My question is this;  
What initial torque readings are you, as a rebuilder, shooting for? Your 
range of "acceptable" readings. (For example, - above a certain torque you 
would stop and work to lower the torque by perhaps drilling a larger hole, 
below a certain torque you would stop and work to increase the torque, by 
perhaps  drilling a smaller hole.)

Easy Survey!

" I strive for _______ to _______ inch pounds 

of torque in a new  ___(type)___  block, 

and ______ to _______ inch pounds when 
repinning an old block that is in good condition."

(cut and paste the above sentence and then fill
 in the blanks for the "easy" survey part)

Inquiring minds want to know.

Thanks,
