After a bit of fiddling about I got the cylinder front and motion plate for the inside motion made and assembled.

The fiddling about was my own fault, I initially made the motion plate too shallow and therefore it would only accept the slide bars at their very ends and I needed to mount it further along. I was also considering adding the valve guides and after spending some time fettling the rather misshapen castings I realised that they wouldn’t actually be seen so decided not to go any further. After considering them I had started to remake the cylinder front plate in order to accept them but in the end used it for the replacement motion plate so it worked out perfect in the end if a little convoluted getting there.

One beauty of having a mill is that cutting out the centre section of the motion plate was so much easier than using a piercing saw and files as I have done in the past.

I may yet need to cut the ends off the slide bars but I won’t know for certain until I start assembling the chassis.
