Just to let you all know whats been going on, The new fiddle yard board were built awhile back, the extension boards for full length have also been constructed. The new decking was the perfect location to see if the boards would all fit together in the full length, as I knew that the decking was level.
Cork was glued to the tops of the boards, using Contact adhesive. Only to notice that some of the less than supported sections of MDF had bowed slightly. Some of which could be sanded out, others required to be filled in. I used an Australian made product which is guaranteed to not crack.
The corner boards have been modified to accept the new fiddle yard boards. This means that the entire layout is now a clip together process.
Finally if you are in the area we look like being at the next AMRA Exhibition at Caulfield Vic 2011. So you may be able to view the finished product.
