James,
Hope these pics maybe of some help. The profile is a bugger to replicate. The two rolled outers are the same, the smaller "V" for the sealing rubber, the "U" for the glass (with a rubber "U" available at auto glass places to seal the glass). These four parts were TIG welded together. The square hole in the centre is to fit a 5/8 x 3/8 piece of steel key, which is used as the joiner for the two completed halves, so you can fit the glass then slide the frames together.
I am too embarrased to say how many hours I spent getting this far, and had just about completed the basic lengths when I dcided that some old ones I came across would get me on the road this year and I put the job on hold. Then of course you have the Hinge along the top (these are usually saveable), the side pivots for the arms, and here in Aus. at least the extra pivots for the handles on the bottom.
This is an intricate job, and when someone sorts out a quick way of doing it, they will make a fortune, unfortunatley it will not be me! Good Luck !!
Rich.
