Mustang Seat Frames

Looks good . So then what are you going to do ? Make ply wood frames for cushions and the screw them to the aluminum?

The plan is to take the frames to an upolsterer and tell him to make some seat cushions that fit. The cusions I have seen have plywood or some other material (some kind of synthetic) backing sewed into them. With female threaded inserts in the wood so I can bolt through the frames to hold the cusions on. I am not an upolsterer though so I think I will just leave that part to them - we'll see.

64 Skier, my thinking is that with some material in the cusion (plywood or synthetic) of about 1/2" thick, when the cusions are bolted to the frame there will be enough rigidity. Again, we'll see.

Also, the 1/4" risers on the back are doubled when welded, to 1/2" and again the back cusion will have a 1/2" backing plate inside it also. The 1/4" flat bar riser above the welded risers is only the top 8" of the riser. Plus there are two 1/4" thick cross braces welded across the back for a total of 1/2" of thickness leaving only 4" of 1/4" aluminum on the back cusion risers. From a practical point of view, the aluminum back cusion riser part of the frame is 1/2" thick not including the 1/2" of rigid material in the cusion.

If I get too much flex I can always weld on stiffners but I don't think I will need them. Again, we'll see.

Here is a pic I found somewhere. I am using the pic as a model. Thanks to who ever owns this boat and posted the pic.
