+1 for turning off the square capital and using separate pieces which are free to turn on the longer threaded portion of the column. That is what I did on my first table engine, not a James Coombes but a Stew Hart. I actually drilled and tapped the columns to take studs to save making all new columns.

Jim

Coming back to the original question, if you have not got over it by now than moving the supports to another position is also an option and one that I have gone for on my much modified JC.

I'll be doing my conrods in the next week or two if you have any questions Wayne, the short one and the yoke were completed last weekend I'm not soldering as per the Stuart design but bolting together.

Wayne, I tend to do most of my posts about an engine once it is finished with just the odd progress shot during the build. But if it helps the photos are being added to this album and feel free to ask about anything. Although I have used my CNC for a few bits it could all be done with manual machines with a few slight alterations, from the look of your No9 you should have no trouble with a JC.

Probably best to start your own build thread on here.

PS the album will default to newest first so either change that or start at the end and look backwards so images are in order.
