Thanks gents,    When I looked closer at the real engine I realised that the con rod bearings are not retained by the usual gib and cotter arrangement :ShakeHead: The joint is retained by two gibs and a central cotter with a threaded end. This thread worked out at 6ba, the cotter end was not much bigger so it was  a bit of an education for me to be on such a scale.....OK, I realise that 6ba is HUGE for a lot of you but come on, I have just finished a 4" scale lump!      Terry

After yet another long interuption of "shed" time I have managed a little bit of progress.  Not being happy with the first set of slidebars I have made a new set, progressed the bed and started on the cylinder.  I cut out the bed for the cylinder and forgot to allow for the flanges :facepalm2:
in spite of having made a set of drawings :old: Had to cut the correct size aperture AFTER I had put some primer on. I will be following Jason's excellent system for the cylinder. It's good to be back making swarf again.   
Something that I have noticed is that when using small cutters on my mill with the knee raised, it is hard to see the work. Visibility is so much better on the "quill" type mills that so many of you use.
