Elevator construction

It doesn't look like much, but this piece took way longer than I planned! All the other pieces were simple, straight bends in the .035 sheet steel and I expected this one to be the same. But, this one was curved!

I'm sure there was another way, but I solved it by using two pieces of .035 sheet, curved easily at the top for radius and curve, then brazed everything together. Sanding and filing hid the seam.

I was not happy with my first attempt. I was so worried about clamping it tightly to the tube, that when the torch heated the metal, the clamping pressure pushed the sheet steel around the tube at the bottom end (the free ends pushed together). This changed the angle of the sheet so that it would no longer fit the wooden structure (too concave, if you imagine).

So, off came the first attempt.

From what I learned, the second one turned out satisfactorily. See below.



Here is the piece on the stabilizer. Notice the curve in the trailing edge.



Enjoy

Brian
