I decided to first to amend the plan of the Trailing Wheels so that I had the correct sizes  before I started to take any cuts.

The amended sizes are as shown in hand written notation.


Before starting the Trailing Wheels I completed the profiling of the tender wheels.


Both Trailing wheels Faced back, drilled and reamed, faced front including the centre boss. Both ready for bringing to diameter on flange and tread and profiling both flange and tread.

Completed the profiling of the trailing wheels and that only now leaves the fettling of all wheel to remove casting flashes.


30th  May

There was quite a lot of flash materials from the casting ( you cna see that ins the photo above)  which needed to be fettled away so a happy coup[le of hours spent with the file !!


31st May

Some repair work to the Dynamometer Car. When tested last Sunday the local speedo decided to fall off. So a new bracket and fixing were devised and completed.


Also the holes to take the coup;ling to the loco were required to enlarged a little so that the pin could drop in more easily. so the holes were drilled out to one drill size bigger than 1/4"

The two holes in the coupling are there to accommodate 5" and 3 1/2" locomotives

I checked the concentricity of my self centering chuck and found it was in error of +/- 2 Thousandth of an inch !!

Then I proceeded to turn the tender axles


First effort !! Finish on the outer part not very good !!

I will be using Loctite 638 to secure the wheels to the shaft as the notes show it has good gap filling ability !!

The tender axles are completed

To cross drill the axle for lubrication of the axle boxes a piece of the original stock bar was put in the lathe and a hole drill in the centre, first using a centre drill  then a drill and finally the piece was parted off about the size of the diameter of the bar.

With the hole in the centre the axle was put in the vice with support beneath to ensure it remained horizontal and the machined piece of bar set down on the axle at the point where I wanted the hole hole.

Drilling then with the same drill as used to drill the hole and some cutting fluid applied it was an easy job to cross drill a hole and meet the existing hole in the axle.

5th June

To try to avoid any errors the driving axle was converted to metric.

Completed the machining of the Driving straight axle and remade a tender axle, including the cross drilling as I was not happy with the finish on the Axle Box running surface.

7th June

Tidying up some of the excess flashing on the wheel castings more still to do
