Well I am still at building base board after baseboard. Work has progressed on baseboards 10,11,13 and 14. So I am nearly there. Baseboard 12 - I am not entirely sure what to do with it yet and it won't affect the main running of the layout so I am probably going to leave it for a while before constructing it.

I am now at the more complicated end of the loft where I have to build the final corner which includes a removable bridge piece of the access walkway as well as being on a double deck. 

Some of you might wonder why the bottom board of baseboard 10 and 11 doesn't extend all the way to the back and this is because I need to get easy access underneath to do the wiring. Wiring will be fairly simple here as im only using insulfrog points and dc control on the top deck but there still will be quite a few lights and other animations that I am planning plus point motors.

This is the design im using for the bridge, I have watched quite a few videos and this guys bridge seems to be the best method.

Making my lift out - Part 1 - YouTube

Ive used 12mm ply for resting the bridge on because I need to cut out the slots for the metal contacts
 

I have sourced the dowels that he used and do agree that they are the best for lining things up. My 9mm ply and 12mm ply is just thick enough to take these dowels. However I don't have to worry much because there is a 2mm cork sheet being placed over the top as well.

Baseboard 14 was installed and then I decided I didn't like one of the corners that is protruding into the room so its currently back downstairs where I can cut off a large chamfer and rebuild the frame. 

Baseboard 10 I got installed and then realised that I had built the top deck too far out and measured it wrong off the cad drawing so I had to rebuild it. (A lot of to and froing with the boards up and down the loft ladder!) but thats now in and butted up against baseboard 9 and 11. Baseboard 11 I mis-measured the top deck so had to cut a small chamfer but it will be fine once covered over with cork and scenery. Baseboard 13 I have a height difference to sort out and a leaning problem on the top deck so a bit more thought on the frame is needed here. Probably needs some triangular bracing.

I had a general tidy up of the temporary controller area and added a auto reverse shuttle that I built from a MERG kit last year to the rear top deck track so I can go hands free despite not yet having a tailchaser loop.

Did a lot drilling for wiring holes and bolts in all board frames
