Since the tramming I cant wait to flycut something. I was able to get my tram down to stay perfectly on zero on the front to back(Y). On the side to side(X) I was able to get down to the needle just starting to waver off the line. If the indicator is anywhere near accurate it would be less than .00025. Did take an hour or so but next time it will be much easier. Thanks again. Dont know why I put it off.
I did the same :) Just after tramming my mill I built this slotting cutter for my shaper shown in my hand in this article at Metal Working At Home dot com, "The First Law of New Projects"
Note the intersecting arcs from the flycutter - indicators of excellent tram.
Spudzwon, thanks for the response. After watching this, I watched your other video using the granite plate. Having been in the flooring business for years I just happened to have a piece of polished granite tile in my shop. I placed it on my table, ran the coaxial indicator around. Turned the tile a few times to make sure the readings were consistent all the way around (they were immeasurable with my tools) less than .0005 difference. Had to shim the head as it nodded towards the operator.
Clear and to the point. Nice work. How do you know to trust the rotors flatness to adjust tram? I can see the way you used the rotor for the centering technique and that makes sense. I am just not sure if the tramming would be precise. I am only guessing as this is new territory for me. I have just started to adjust the tram on my DM 2400 to get the best finish within my abilities so far. It was wasted effort on my Sherlines or I would push it too hard! Anyway just looking at techniques.
I chucked the rotor in my lathe and checked for parallelism, and put in on a true granite surface plate to test for flatness. It is flatter and more parallel than I require. Brakes need to have very parallel surfaces so they don't surge while braking, so this wasn't a surprise.

It is flatter than the table of my mill, in fact.

Too bad, I'd show up with some manapua and poke. I'm in Pearl City. Got a bunch of CNC and a few manual machines.

You in Honolulu?

Nope - I'm in the other land of aloha, Seattle, where the tradewinds stop and the rain begins. I'd rather be on your end of the Pineapple Express.
