Brief Description: Seats Part 1
|
|
When it came to the seats, I took into account a number of issues I collected over the years. The plans say to rivet aluminum sheet as the backing, but there had been some reports of the seat frames cracking with all the rivet holes. I had seen some seat refurbishing videos on youtube that highlighted the use of dacron for the same purpose, and gluing the fabric meant I could avoid the rivets. So image 2 shows the dacron wrapped around the seat frame, and I included two rows of seat belt webbing (front-to-back) under the butt, to add some strength over time.
For the seat foam, I followed a post from ROger Hoffman, who built up his own seats with memory foam: http://tincantimes.dcsol.com/SeatCushion.htm (photos no longer work).
Copying Roger's process, Image 3 shows the foam layers I used: Standard 2" high-density foam on the bottom, followed by layers of different density memory-foam from E.A.R. Global materials.
Green is the most dense, blue is medium density, and pink is the softest. Image three also shows the triangular material used along the side and front of the seat to provide more ergonomic thigh support.
