Thanks for your suggestion.
I will give it a try, but without a pillar drill don't hold out much hope in getting the holes vertical/parallel.
I've also found this suggestion:- https://www.scalefour.org/forum/viewtopic.php?f=20&t=2019&start=50#p18358
The required crankpin throw is 8" which equates to 2.6mm, will have to see how accurately I can measure & mark up.

Mark the centre line of the crank.
Then put a 1/8th rod through the Axle hole so that it protrudes slightly onto the front.
Put a bearing on it with a notch of the correct depth.
Then put the notch over the centre line and drill in the gap

All I need to complete the Underframe kit are some Buffer heads to fit my shanks. I will make the heads and have them lost wax cast after scaleforum.
Then I will do the online instructions.
