Large Internal Sliding door V2

[ultramods]

Last year I asked about how best to create a DIY large sliding door, 3300mm wide by 2650mm high, the consensus was the best approach was a stud.carcass timber frame covered by 6mm ply or MDF.

 

This is what I was planning to do. However I had a cabinet maker in the house to quote for making the stair treads and he noticed the runner in place for the large door and asked when I was planning. When I told him, he said he would not use normal softwood timber for the carcass as it will warp over time. Instead he recommended cutting up a sheet(s) of birch ply length ways into battens and then gluing them together to make the carcassing timber. However I forgot ask him to specifics.

 

 

Can anyone recommend what thickness I should go for 2 x 12mm or 2 x 18mm ply.

What depth should I make the ply battens, I am thinking 38mm (the door needs to be around 50mm, including the 6mm covering sheets)

Is it ok to glue all the strips of ply lengthways in the same direction/orientation?

 

Do I need to use birch ply or would any hardwood ply be ok, since it will be covered by a sheet of ply or mdf

 

What intervals should I have for the horizontal and vertical ply battens that make up the door, how about 660mm?

I am going to start making the door this weekend. For the structure I have 18mm x 40mm x 2400mm strips of birch ply. Can any one suggest the best way to fix the strips together to increase the vertical and horizontal strength. I can't decide if a T, I or 4 pieces would be best, in terms of strength, weight and actually assembling it.

 

Also what is the best way to fix the strips together, glue with screws or use a framing nail gun or finishing nail gun. Also would I need to clamp the wood whilst the glue sets even if it's also screwed or nailed?

I love this stuff for quick and simple joints that are incredibly strong. Pin it every 150mm with finishing gun.
