Then the winter job will be to get both boards out and replace with something heavier - perhaps adding some floors to take the sideways forces. When this occurs I'll probably take the inner mouding out in 3 pieces and re-do the glass joint round the board casings.
I'm open to any advice or input. If Dave Cawston is still looking - do you have any experience of the glassed-in ones? Is it a feasible idea to grind the glass away from the upper side of the pins and remove them?
First thing will be to cut an access/viewing hole in the saloon seat - I'm not sure how close to the centreline the boards are - or to put it another way, how far outboard they are from the inner face of the saloon seats.
Hopefully someone on here will know otherwise I'm going to have to measure-and-guess!
Then I'll be able to see how to drop the board. Once out, a grinder plus a lot of CSM, followed by a lot of sanding...
