Stobe slipper gearing question

[sjcrss]

I ordered the 4mm shaft 13t mod1 pinion....and I will see how it does.....the gearing is pretty close to what I was running and on the 32p setup i could of gone as high as 15t....which would of been...
15t/66= 4.4
13t/51=3.92

which is pretty darn close....if I have to I can allways order a 12t or even the 10t....but I don't think I will have a problem now.....we will see.
also thanks for the help guys...much appreciated.
