QX100: upper seat broken: missing seat support? welding possible?

actually the pic of Thorside shows a proper range of washers etc.... http://www.thorseat.eu/wp-content/uploads/2017/08/crews-640x480.gif Therefore you could add a nylon and a rubber washer.

I have spoken to three metal workers:
They all recommended to drill a 2mm whole at the end of the crack (afterwords sanding of the whole, minimizing sharp edges), bending hammering or bending back the alloy if possible and filling the crack with two components metal glue. The best would be soldering.
One has recommended to mount a 25x40 rectangular alloy on the side where you sit.
I will first try the wooden seat I was given and if this seat does not work out, I might drill the two whloes and use metal glue (it's important to have a clean and fat-free surface before glueing.)

if you look up on Facebook the group ozhpv recumbent for sale swap there is a seat of the right colour for $50 at Coffs

Thanks a million! Just checkt DHL: about 140 Australian Dollar plus 50 for the seat.
I could adapt my wooden seat a bit better: it has got a headrest now; feels much better. Alpha stage... Will buy one round foam roll with a diameter of 12cm if this "construction" works out. The bacchetta mat is temporily fixed to the seat (is going to be replaced by a ventisit). All depending on my back (whether or not it likes the seat line; the angle is about 40 degrees now). Weight is a bit less than 15kg (might be a bit lighter with the ventisit mat).
