Now its time to start the longest most complex and frustrating part of the build. The sliding doors. I didn't want a big over head door that would block the overhead lights when it was open or reduce the ceiling height. So I looked at barn doors, sliding doors, carriage doors, and coiling overhead doors. All had the pros and cons. I liked the barn door look but they don't seal or secure well. Carriage doors are beautiful. Are easy too seal and secure but large openings tend to have issues with sagging. Coming overhead doors have one con. They are ugly. Sliders are a good compromise but can be heavy. I talked to hanger door manufacturers to see about having some tabbed but the size I needed was not efficient or cost effective. The steel fabricator that put up the steel frame said he could make the tracks, rollers and frames for me for $4500 and he would install the tracks and set the frames inplace. That seemed like a fair price for custom frames and track. All I would need to do is put the skins on and install all the weather strip. We agreed on the design and cost in April. The driveway was poured in August with he blackout for the lower track. The track and doors didn't arrive until November. One thing after another kept getting in the way. Big job out of town kept him out of the shop. He hurt his back, someone was sick. All legit reasons but I needed doors. I started hunting other fab shops to complete the work. I was willing to buy what was started and have some one else finish it up. Finally all the pieces arrive and I paid the cost of the fab work and did the install myself so I could close in the shop and finish the interior work.
Here are some sketches of different door designs we discussed. The custom lower track milled from 6061 aluminum, and the recess in the driveway slab for the track.
