How do you fit brass coach sides to roof without gaps?

[Noel]

Hi Guys

 

In light of my ongoing learning curve painting old RTR coaches, I am wondering if I could ever become proficient enough to use etched brass sides to convert or improve RTR stock (i.e. laminates, bredins, etc). These are probably questions for specialists like John M, and/or others who have successfully used brass etched coach sides with RTR or plastic coach kits. The questions are:

 

1. How does one successfully use etched brass coach side overlays but avoid the sometimes seen air gapping between the roof along the sides in places, and also avoid the sides sitting flush or even proud of the roof, which instead should often overhang the coach sides marginally (i.e. often with a drip rail)?
   .
   
2. How does one ensure the brass sides do not finish short of the roof ends or coach ends (i.e. finish either flush, or have roof ends very marginally overhand the coach ends)?
   .
   
3. How does one form the tumblehome without specialist tools, or do some suppliers of etched brass sides supply the sides with tumblehome pre-formed?
   .
   
4. Is it better to have the sides fixed to the roof and coach ends with removable chassis and under frame, or visa versa (fixed to the chassis and ends with removable roof)? Does the latter risk air gapping?
   

Many thanks in anticipation.

It's late here, Noel but since no-one has been on as yet, I know that Mayner usually recommends the the etches are fitted to the side of the donor with only the space between the window themselves removed, with the top an bottom left in place to fit to the chassis and roof. He suggests gluing the roof for stability and have the entire thing removable from the chassis. His are designed for a Dapol kit which is a scale 60' which is not the usual 61'6" frame standard on almost all of CIEs 1950s built stock except the very first few composites. Scale 60' coaches required, I think. The tumblehome would be whatever is on the donor coach. NZ will be awake shortly I'm sure

"Converting RTR coaches with Comet sides" on the downloads section of http://www.cometmodels.co.uk/ gives more information on fitting brass sides to RTR coaches.

 

Worsley Works has "shortened" sides for some modern GNR & NCC/UTA coaches to fit RTR bodies.
