The tender was started some time back the frames were machined from some brass strip with the axle box positions marked out for a 6 wheel tender not a 8 wheel tender as the A4
The main fixing holes were drilled in the frames so that the screws would be in the best places within the new plastic insulator i had made but all this was in vain as in the end I used the Hornby insulator.
All that was needed was to file the new axle positions in place which you might be able to see in this picture below.
The chassis will be fixed to the body by 3 screws 2 small screws at the front and 1 larger screw at the rear this will be a special screw so that a Hornby coupling can be attached to it.
Having a model which has a body made from brass not plastic gives problems with electrical insulation.
So to fix the chassis to the body some sort of insulation is needed.
For this I used some small strips of printed board one long strip at the front and a shorter strip at the rear of the tender. You can see these in this picture and these were held in place with 4 small screws drilled that tapped into the top edge of the frames.
The axle boxes were held in place with another long section of printed board fixed in place with 6 screws again drilled and tapped into the bottom edge of the brass frames.
This printed board would have 4 small brass brackets soldered in place and the frame sections from the kit with the springs and axle boxes were going to be held in place with 4 screw 2 each side into these small brackets as in the picture here.
I had a go at trying to add the fine detail into the ends of the tender and going by my Hornby model this is the result not 100 % but it will have to do and if I drive it fast enough people will not see it that well.
Once altogether the tender was looking pretty good the next part is to fit the hornby boiler which just about goes in nicely Then the wiring can go in and a working rear lamp.
I've had the boiler sitting in a bowl of acid to give it a good clean so with a new heater and thermostat cut out I can try it out with a few steam runs soon.
