Colin and Norman,
Thanks for your collective inputs. Norman's Tubal Cain version is the one that uses most of the castings that I have aquired with the exception of the main top section that holds the weights, that's missing.I'll have to machine that from solid.
Colin's version appears to be the later one from Stuart Models that minimises the use of castings but like Ian's I will finish up with a hybrid of home made bits, It's going to be fitted to an S50 eventually.
Ian, I'll study your version in a bit more detail later but it looks good.
Thanks again lads and Seasons Greetings to you and to all my readers!!
P.S.
I've ordered the Tubal Cain book on building the Stuart No. 9 from Waterstones (on line) for £6.26 plus free delivery. Amazon had no stock..
I think I'll look at Waterstones again in the future, makes a change from Amazon.
