Next I wanted to machine the rear of the bore and after giving it a little thought I decided on using the boring head in the mill for no real reason other than I can see what's what a little better when in the vertical orientation. First picture

Now we come to one of those jobs that I am most apprehensive about, it's not that there's anything particularly difficult about this but there is very little, actually probably zero allowance for any error, we are of course talking about the middle cylinder. I knew

A little more done to the cab today, this time the washout plugs and cover. I have followed Don's overall dimensions with a slight change in design, I'll explain.. the picture shows one cover after most of the machining has been completed, IIRC dimensions are flange

Today I made a start on the window frames, I made templates for the side windows first although forgot to take any pictures of these. there's not much to see on these yet anyway, just the basic outlines cut in alloy to check for fit and that the

Now, I stated early on that I would make this a removable item, this is for two main reasons, first it gives me a better view of the manifold and the various working valves associated with it, second, it will allow more light into the cab and thus help me

I then made a start on the cab, again I have made use of Malcolm and laser cut parts, this cab when completed will be highly detailed, I plan to include everything which is humanly possible and it will all work. So I have set myself a heavy task and

Onto the first motion parts, I had planned at this stage to start stripping the frames down ready for paint but when reading a fellow model engineers update in regards to machining the radius to the axle boxes to allow for tilt I remembered that I wanted to get the

Something that needs doing now before moving on much more with the chassis assembly is to make the sander rear mounting plates and drill/tap their mounting holes before painting the frames. Also before I can strip everything down to paint I have a few jobs to get out of

All of the crank-pins have raised steps that sit flush with the wheel boss at 19/32nd diameter so each started off as a piece of silver steel at that diameter.The first job was to machine the spigots that fit into the wheels, these are 9/16th for

This isn't news 'per se' as I've had this casting for some time and in fact have machined it but since it's now appeared in the log that I'm slowly copying across to this blog I'll include it

Next up was the steps, both front steps and cab. I made a start on the steps beginning with the front brackets that are fitted to the bottom of the spring housings. I've used some 1.2 mm steel that was in the off-cuts box, it'

Next was to make a start on the ash shield, again something that I'd added to the model to follow the prototype. I am using some 1 mm steel here as it looks right and was what I had in stock. Picture shows the steel cut out roughly
