Earlier this month I posted a wanted "ad" for a window channel - the bit that sits on the bottom of the door window and upon which the regulator operated.
Thanks for your suggestions Tom and Adam but no luck. Several troubled nights with the little devil on my shoulder wispering "go on , you know you want to, go on, make one!, how hard can it be ?!!
Here's how !!!
The old channel was totally screwed.

Startpoint was to measure an unrusted bit of the old one - hummm 18g - got a sheet of that somewhere.
Some layout work, some nibbling, and folding began.

The clamps, the clamps.

Coffee, a good scream, more coffee and the channel took shape.

Next, impress the track for the regulator wheel to run in.

Voila!!

Now just form the lower guide.

A dab of paint - and :---------------------------------------------------------

Now - that rubber moulding that fits between the window and the guide, how hard can it be ?? It all starts with a tree leaking latex - hummmmm.
