Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

I have my crankshaft in bits right now...26, ew
  the oilways,  I have the screws out and have drilled out the charcoal there anything that will dissolve the burnt oil in the rod race pins...I have excavated down to where I think the threads start...but now need to do a right angle to get the oil way clean...
is there anything that will dissolve the hardened oil??
I don't want to remove the  crank pins...they are staked in place
if I cant get these oilways clear...I may have to drill a hole through the face of the crank into the oil drilling to feed my rods..1/64?
I bought 5/16 rollers off ebay and have the races ready to harden tomorrow...
I found also that valves from an MGB will work as well..the head is the same size...the stems are bigger but are tight enough that the original guides just need a ream
I just need to cut them off and cut in the cotter rebate

still looking for a picture of a girder fork top nut


Perhaps an soak in an ultrasonic tank will loosen the carbonized oil.
