Not a dumb question at all.

Where the marker wears off will indicate the high spots or contact points.

You should understand the bolt design in order to get the optimum fit. Not all parts you mark with black will necessarily be designed as contact areas.

Each time your arm falls off, (A Bear technical term, Scull) clean up the mess, look at the black area and determine if you are still improving the fit.

It will be easy after a while, the lapped in areas will look polished. As you near completion, and after your cleanup, put a dab of oil on the bolt and run it home a few times to feel for results. If you want a better fit, clean the lube and replace it with more lapping compound. Cycle the bolt again until your arm falls off again. (See technical lexicon above.)

Do the clean-up and start the procedure over again until you get the results you are looking for.

Remember the object of this exercise is not the removal of the black marker, that's just another tool in the process. The end to this lapping process is the subjective improvement or fix for your "stiff bolt problem".

Oh yea, come up for air every so often and post your progress.

Good luck.
