I have now made some more corrections, since I found some other mistakes.
1. The exhaust has been replaced with one of correct length. I had also managed to get ugly kinks in the bends which I did not like. The new pipe was done correctly, i.e. a ran a length of brass rod into the pipe before bending (same diameter as the opening), and this eliminated any risk of ugly kinks. The brass rod is slightly shorter than the pipe, to allow for the opening at the end.
2. The "stowage box" at the rear of the roof is in actual fact a metal frame with a lip along the top edge, I had made this as a solid, thick frame thinking that it was made of wood. This has now been corrected. the fixing brackets remain to be added.
I have also added the fuel tank now.
Other than that, I decided to try out the very nice Fruil tracks, so the last four pics are from this "quick trial".
It is possible that the tracks are on backwards in the pics, I will make sure that this is corrected in that case when they are put in place permanently. The track links are only press fitted for the trial (its a fairly tight fit, but I will use the provided wire to make sure they don't separate).
The tracks need to be about 1mm above the edge of the vehicle (all around), so I will add a guide to make this happen. A test guide has been glued in place for this trial, but I think I will need to make it slightly higher.
Idlers and sprockets are included in the Fruil set, but since I have already glued the plastic ones in place I will not use them on this model. They are barely visible in any case.
That's it for now, thanks as always for looking!
Cheers,
Sven
