I tried the principle. I bent the sheet metal profile 1mm. 20 x 30mm I copied the inner wall of the frame. I used EW to indicate the shape.
I will try to use Pullmax or make wheels for EW. Both seem to be possible for this task. After shaping, the 20mm edge is cut off.

This looks good, Jaro.
Two pieces welded may be easier than making one long snaky one.

Thank you Kent. I made 2 plastic pulleys for my EW. I'll try to shape the frame and finish the profile with pulleys. For the last bend I'll try to use Pullmax. I had no time.
I moved a beautiful hydraulic press. He needed a little cleaning and a function check. Change oil. For 12 years he stood in the garden under a tarp. Here it freezes in winter. Lis jumped as if I had turned him off yesterday. The perfect machine. Piston stroke is 600mm. Universal machine with very precise adjustable range of ram. It has only 25 tons of pressure, but for those things is enough.
I will send result and my way.

25T is a very useful machine, Jaro.
I have been resisting a 250T four post for a while ....

Yes Kent. If you need to test the mold for a part, it will show you the exact shape without risk. Then you can put the tool in the crank press and speed it up. It is applicable for bending and forming on simple tools. You have the possibility to precisely reach the ram and adjust the pressure according to your current needs. Very good machine for toying.
250t is a beautiful pressure, but it already wants to produce for industry. I think we'll go half the throttle and we'll have time to look at the girls and not have to fill out the monthly time sheets. I leave it to fools and youths with a mortgage.
But I intend to produce a bottom press for sheet metal tensioning.
This will be another task.
I tried to advance to the frame today, but I didn't have a camera. So next time I'll send the results.
