Stop the presses! MH repo roller project weekly update

Ok group,
    Here is the weekly update on my project and its not as bad as the
subject line might seem.

The Good news:
    I will have steel rollers for stock Atari MH controllers done by
next friday. I made them out of
Thompson Shaft, which is a case hardened material that you use in
automation to run ball bearings
over. The shafts are case hardened and were ground to size (not done in
a lathe). I think the quality is excellent
but Ill leave the judging to Jon Raiford as Im returning his controller
to him with the new units installed.

The bad news:
    In measuring things up from the Repro Roller drawing I have come to
the conclusion that I want to change a few things
before I start taking orders on these things.
    1 The green roller that I made is 2.00 wide and I want to
standardize the roller so its good for the repro unit or stock unit.
This will make the roller 2.0655 and will fit into any unit
    2. The steel rollers are all different between the atari and Repro
unit so Im redoing this to be the same as the atari parts so that again,
one size fits all.
    3 The change in item 2, means that the bearing holders need to be
thicker as the Atari steel roller is shorter then the Repro roller
I haven't documented the changes to that yet but I will. I will follow
this letter with one with the FS tag on it. If anyone was looking for
steel roller
you better turn off your filters.

Here is a side by side shot of the Green Roller and the Repro green
roller. I will be resizing and changing the angel on the corners to
match the Atari roller
The picture is more or less for color comparisons
