Hello Mark
Knowing that the Trent was going to be a difficult build I opted to build the cabin in one piece without the removable roof this added a lot of strength to the structure.
The joints are "knife edge" and the only way around this is to get it right first time.
Don’t mention how fragile the model is to build just you wait until you first sail it, I can only compare it to sailing a model made from tissue and just as delicate, I have lost count of how many times I have had to make running repairs at the lakeside as bits drop off.
When building the model I first made 260gsm card templates and constructed the entire cabin out of card as a one off template so that I could get all of the cuts just right.
Hope that this is of some help.
If you are local to Warrington my Trent will be on the Lifeboat stand at the Birchwood show and I would be happy to talk you through the finer bits of the build.
Paul
