For the amount of machining that was necessary, you are about right on the time. If you were power tapping, you might be a little slow. Machining looks great. And you even deburred the parts!! If you want to really slow down, make all of those holes 00-90 thread size without breaking any taps
I had better find some real wood to knock on after that comment
I have yet to break a 00-90 tap
Must be really living right. Wont talk about M3X .5 though
