reconditioning gears and sliders
I observed that it is usually 3 adjacent dog teeth that have wear (and 180° apart another 3 teeth). When back cutting the slider do you cut them in an angle (the later sliders have this feature from the factory and I think it's called torque lock)?
Take another look. The coast side is usually 3x2. But in my experience , the drive is usually more like 4 or 5 x2
When back cutting the slider do you cut them in an angle?
I use a hand-held electric die grinder with a small grinding wheel, about 1/16 x 5/8, and cut a shallow divot with the edge of the wheel. To fit that buzz-saw in there, I have to hold it at an angle. Not very scientific, but they get what they get.
I was taught this technique in 1978 or so, by the line-foreman in a rebuild shop. I replaced the previous guy, who supposedly sucked at it. As soon as they figured out I was teachable, they moved me into ever more complex stuff. Stuff that they had never done before, because they had never had anyone that could do it,lol. I felt pretty important there for several years.

They started me out on 3-speed Muncie pick-up transmissions, with non-synchronized low-gears. I built hundreds and hundreds and hundreds of those.
My favorite transmissions to build were the RoadRangers. These were installed into 18-wheeler hi-way tractors. We call them semi's up here. They were born as 9-speeds but very quickly evolved into 13s,15s,18s, and eventually 21s. But I quit that job before the 21s showed up.
