well just when I thought it was all back together... I'd gone down to work with the intention of refitting the oil-bath air cleaner, which resides in the back of the militant at the moment. When I went to drop the tailboard to get the aircleaner I noticed that the metalwork around the back end was parting company with the body. I knew that the back body required attention, but I was hoping to do the season, and make a start this winter, however this is not going to be the case. With running, all the loose bits etc are simply falling off. The rear crossmember that the tailboard hinges and the rear floor sits on, was rotten in the right hand corner, I knew about this but thought it would hold up. The wood was disintegrating and leaving the outer steel surround which is only a couple of mm thick, to take the weight of the hinges etc, so as a result it was starting to bend.
I had thought that I could splice a bit of wood into the affected part, but realised that to do this I would need to remove the tailboard, the hinges and the outer metal framework to gain access. After a short while ( 2 hours) all the bolts were out, and the metal was removed, as is so often the case the wood behind is completetly shot, so it's a new crossmember.
I'll post some pictures later.
