My new home made center sliperential

A 22T is 24mm diameter, and the 23T should be 25mm.....Hummmmmm!!! it's a full 0.5 mm all around, so i think that it'll be to tight, but if somebody have a 23T for me, i'am ready to try it.
Because i don't want to order just a pinion from Mike, it'll cost $25.00 just for shipping

I've try the gear mesh with a Kyosho 46T plastic spur and it was not to bad, but with the steel one, the mesh seam to be a litle on the loose side.
Maybe it's the theet shape of the steel one that's not the same.
