Hi there
Still beavering away at LBSC's Tich, allegedly a 'simple model for beginners'!! I have made reasonable progress, I think, and have just completed maching the cast crossheads. This engine has a single slidebar arrangement and the crooshead has to be machined to fit the bar and then a piece silver soldered on top to create the bearing surfaces. This proved to be a right b*gger of a job and, although I have completed them and moved on to fitting the cylinders, I am not that happy with the 'fit'. Has anyone else had experience of these type of crosshead in 3 1/2" gauge?
I fell foul of the problem of 'excessive' solder warned about in the book (despite being more frugal than a very frugal person with the solder) and used the suggested solution of a 'punch' made from the slidebar material to clear the way again. The crossheads are good side to side but are a little loose up and down, possibly .003" or .004" ish, not too sure how this will affect the running.
Cheers
Brian
