  • I haven't made anything for seat covering yet. The method Bob suggests in the seat build newsletter is lightest and best. After a friend used my shear to make .020 aluminum strips for his Legal Eagle ultralight I'm going to make similar type lattice work for at least the seat bottoms. I will treat myself to pro made cushions for the front seat but the rare pax will probably end up sitting on wal mart boat cushions. Thanks for sharing your project.

      I had to look it up....The Patrol Book the came with the plans shows Bob's method is to use 3.7oz Dacron Aircraft Fabric glued to the seat frame with PolyTak, wrapping the cloth 75% minimum.

  • For the seat bottoms, I am hesitant to use the Bob method, because I'm a pretty big guy. So I looked at the Tony Bingelis book, and adopted his "metal lattice" method for the bottom of my front seat – the one my big butt will sit on. For the rear seat bottom, I'm using a simpler aluminum sheet with "fingers" extending past the seat frame, wrapped around the frame and riveted to the seat bottom, similar to the lattice-method. I will probably cut some lightening holes in it after I'm done, but it's not too heavy as is. Really the weight is similar to the basket-weave front seat.

    • Hi Jim, That is what I was considering doing, with the aluminum but I was not going to use the lattice I was going to use the sheet aluminum and cut lightening hole like you said, but I talked to Btaz and he is using the fabric method and he was telling me that it was very stiff and did not give after it is shrunk. I was thinking I could try the fabric and see how it does and if it doesn't work out I can always remove the fabric and put the aluminum on. I was thinking the fabric may be lighter than the aluminum too.

      • If you're a "normal" sized guy, I'm sure the fabric will do just fine. I'm not exactly "normal sized" (unless you're comparing to a grizzly bear), and at my weight, I'm concerned about both crashworthiness and support / comfort over the long haul from such a setup. I'll post pictures of my seat bottoms, if Aircraft Spruce ever delivers the rivets I've got on order... I ran out (again) when I started riveting the rear seat pan into place.

        • I am looking forward to seeing you pictures Jim. Im about a 200 pounder, I think someone said the best way to improve the useful weight of your airplane was to go on a diet, I like that saying and I just might do that.

            • Stinger,
              To the comments your upholstery guy made about your solid seat bottom... That's something I was initially concerned about as well. So I'm using multi-density foam, specifically designed for crashworthiness and comfort (in that order). It was originally developed for military helicopter seats, where spinal compression injuries were common. I spoke to their specialists, and they recommended the "stack" (layers of different density foam) for me to use for my weight.

              But I understand that if you fly where it's really cold, this foam can be a bit hard until it is warmed up. If I lived up north, I'd probably add a seat heater and turn it on as part of the pre-flight. (That would also solve the problem of LiFePo batteries needing a current draw to warm themselves up in cold temps!)

              • That is a good looking seat Stinger. They look very sturdy and crash worthy.

                • Hi Guys, I got my front seat and rear seats finished except for the fabric I'm going to put on the seats. Now on the the aluminum parts.
