ultramods Posted April 12, 2019 Share Posted April 12, 2019 (edited) 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?

ultramods Posted May 9, 2019 Author Share Posted May 9, 2019 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? Link to comment Share on other sites More sharing options...
PeterW Posted May 9, 2019 Share Posted May 9, 2019 I love this stuff for quick and simple joints that are incredibly strong. Pin it every 150mm with finishing gun. Link to comment Share on other sites More sharing options...
