Diesel Electric D16/2 part 3

I've now more or less completed the drawing up of the various parts, although some may yet need alteration as I go along, as has been the case so far.

On the class 50 that I've just completed I made the ends to fit between the sides, on this one I've done the opposite. There isn't much to choose between the two really. The reason I changed was

 

1 on the other one I had to ease the sides out to slide over the lugs on the chassis frame and it caused very minute cracks to open up in the paint, I'm hoping that doing it differently will avoid that.

 

2 I'm hoping the increased width of the end will make for a smoother face because it's the bit that gets the most attention. I wasn't too happy with the ends of the '50'.

 

I felt that some support inside the end panels would be of benefit and hoped for a nice chunky block sat between the sides would be strong. Unfortunately this wasn't possible because the plastic chassis frame protruded up inside the body by 6mm, I needed a 1mm space below the front windows for the glazing, so my chunky block came down to only 5mm deep.

Gluing the end panels to the sides will be more problematic. When I fixed the ends internally on the 50 I just clamped the sides with the end panel in between using a small screw-vice, that won't be possible gluing the ends to the sides. I will have to think up a clamp that's as long as the sides, plus the side panels will need support in between to prevent them buckling.

I've drawn up some fillets to be inserted behind the window corner pillars. These are merely rectangles with a vertical score line, so when bent to a right angle make a fillet 2.5mm x 3mm x 8mm long.

On this model I want to improve on the glazing inside the cab which was not possible on the 50. I've drawn one layer of the end panels with a large cut-out to allow the insertion of some clear plastic to be sandwiched between layers and I've adopted this method with all the glazing throughout, so far it's worked well with the ends. The only problem is that the windows will need to be masked off when I paint the body. I plan either to use the blanks cut-out from the openings reinserted over the perspex or get some maskol when I go back to the UK.

Above is a picture of all the parts cut to date. The red ringed ones show the glazing method on the ends, the orange blue and green ringed are the various side/door windows, the plastic cut outs are just visible 5th from the left. I've taken some pics of the glazing fitted (next three) but thse are not too clear.

The difference between the black sides and the white is the black ones are outside panels, the white ones are inner panels, I just did that to save on Black card which is more expensive, no other reason.

When I've completed the next phase I'll post the details.

It's looking good Roly. ;)

 

Some interesting conundrums to address as well.  It sounds as if you learnt a great deal when building the Class 50.

 

Cheers,
