Setting a 990 anchor...

[!Jones]

The bosses went on nicely, I built a welding fixture that located in
the dropout. I'm ready to glue on the housing anchor... for the 990
brakes, I'm assuming that 4" above the boss centerline will work OK.

Are there any comments on this?

I'm using a Nova STI stop that I milled to fit.

How come Italian threads are given in terms of a metric major diameter
and threads per *inch*? That makes no sense at all!

Converting to a metric diameter is easy - just a simple adjustment to your
tooling. But converting to a metric thread pitch means replacing your machinery.

The metric system derives entirely from some medieval superstition about the
power of the numeral ten and is best avoided whenever possible.

Yes, but I only need a one gram standard mass and I can derive the
rest of it.
