Continuing on with the crossheads and we have 11 pictures for this entry, I have tried to do the talking with pictures in an attempt to give a clear indication of how I am tackling the various machining processes and in which order. Oh, and yes there are some machine

Now this part is going to take some time and I guess there are a number of ways to do these either from solid or as parts. I'll be doing mine from solid except for the slipper which I want to have as a replaceable part, I will

Most of the parts for the slide bars were made some time ago and have already been covered, this entry is the final stages and fitting to the chassis. Before I could do this I had a few castellated nuts to make in two different sizes. Now if following the

Continuing with the various parts to fit to the cylinders, this time we have the 6 relief valves. I have followed Don's overall dimensions but added extra detail and made them fully working and easily adjustable to what I feel is perhaps close to how the full size

Last time I had made a start on the outside cylinder cross shaft and showed the trunnion positions. I then made the shaft, silver soldering it's arm in the middle and making the end arms to connect to the outside draincock linkage. Here's the shaft in

The sum of the parts involved in this design are a little bewildering at times and trying to work out what can be done and in what order is no small task in itself. It's a simple matter of big fat fingers can't fit in tiny

I've been busy over the last few days and getting very close to the final fitting of the cylinders, unless I have forgotten something, of course. First up was to shape the cladding, this time around from 'Tin' to hopefully give a stronger article and less

This entry see's me decide after close scrutiny on the final look/design of the relief valves and permanently fitting them to the draincocks. They are not fully completed yet but I have made all of the components bar the dummy 10BA studs and nuts which secure the
Flying Scotsman
I have left the final fitting of the valves until the connecting rods, crossheads and bearings have been made and before they can be fitted the cylinders and the slide bars need to be fitted to the frames. Therefore this entry will cover the work involved to get the cylinders

This entry will be picture heavy as I try to explain Jim's design and also how I have adapted and then made it to fit my model. For those not familiar with these things and putting aside the various modern materials used these days, the normal practice when

First I'll share the drawing to Don's design, the spindle will of course be the same but the bobbin will be updated to what I believe was first drawn by Jim Ewins in the 80's. I thank all those who have shared their own
Flying Scotsman
Well I did warn you that I might not be doing the spindles/bobbins next...:) The thing is, now that I have repainted the running boards and very happy with the finish, I thought that I best do the smokebox too and tick that box off the list too. The
