Denis,
I'm glad you had a successful Eurotour, I'm sure it will have given you a great deal of confidence in the Ruby despite the brake issues.
I can't see your photos for some reason, but in terms of setting the shoes square with the drums, I know some people have a drum with a segment removed in order to see where each shoe is touching - or perhaps get a feeler gauge in to measure for gaps.
This was my alternative technique: Firstly I made sure the drums were round, getting a couple of them skimmed by a few thou to correct ovality. I used Saftek bonded linings which were slightly too thick and also had slight variation in thickness; these were also skimmed (on the shoes) to make them absolutely round and the same diameter as the drums. Before fitting the drums I put a line across the inside of the drum with a permanent marker pen. Then fitted the drum and turned with a light brake application, next removed the drum to see where the marker had been scraped away and on which shoe it had been deposited. You can then adjust the tabs to square up the offending shoe(s) and repeat the process. Eventually you'll have a situation where the marker line disappears across its whole width and both shoes are blackened with ink.
I did find that the linings needed to be relieved on the outer edge, just on the very corner as they were inclined to press against the face of the drum and force everything out of line.
I hope that helps. I'll let someone else answer your oilite bush question!
