This is good news Nick.
Do you know what tooth style they plan to make?
I think Albins machine is a Klingelnberg.
Shame they don't make 4.125...ratio wise I prefer that.

I have shipped off a Gleason set of 3.88 to get copied Dave.
4.1's are good but a bit weaker than the 3.88 hey?

Yes that is correct nick.

My thoughts were just related to the ratio.

The 3.88 needs a low first tomake it work in most non-turbo things.
Thus first gear may be a tad weaker because it has more teeth.

Just a slight off topic,
I have a 4.125 "O" here at the moment.
Nearly as strong as the "G" 3.88....but pretty rare.
