What do you do when your wife is away for a weekend, you have some blocks of stock kicking around the shop, and there are two jobs that grate very heavily on your OCDness? You put your sub-apprentice level machine skills to the test and make this...
Set lower bottle boss height at the front of the block, align phase with miter, tighten wing nuts...
Pop out block and bring to mill or drill press.
Install 1/4" drill. Zing. Zing. Come back, loosen wing nuts, set seat tube breather hole height on back on block, align phase with miter, tighten wing nuts...
Pop out block and bring to mill or drill press.
Take out 1/4" drill and install 5/16" drill. Zing. Three perfect holes, in phase, at the correct locations.
I can now sleep well at night.
