The original pinions were 24 tooth so I sourced a couple of smaller 13 tooth MOD 0.6 pinions that have a standard 1/8th hole for the motor so I got a piece of 1/8th brass rod and soldered the pinions onto it before putting it in the lathe and drilling them out to 2mm and then re drilling and tapping the grub screw holes.

with the motors removed I made the hole into a slot so the motors could be moved.

To be honest this is as far as I have got its all bolted together but not fully as the shed was getting hot an I went and worked on my 1/10th Brummbar in the house

But I will get it completed soon and should have a more scale speed.
