Wow, me too! That's why I suggested 45°. Ok, up to maybe 60°. It's enough to squeak, and seems to me to be plenty tight and solid. It's typically more tight than what I removed. >I've used washers and counterbores but > am not wholely satisfied with those techniques because of their inherent > disadvantages, namely time consumption and flattening the shoulder at > the base; so I'm looking for options. Washers and counterbores for alignment, or height control? For alignment, if you have four or five more of any type agraffe than you need for the set, you have enough to do the set without modifying any, adding washers, or cranking them down excessively. You just need to find the right agraffe for each hole, or the right hole for each agraffe, whichever. Make yourself a spinner wrench, and trial fitting takes seconds apiece.
