A bit of progress...
Here's a close-up of one of the scratchbuilt throttle linkages, using my "low tech" (no tech??!!) approach...paper clip wire and sheet aluminum cut from a pie pan!
The hatch hinges are made of sheet styrene and a bit of sprue. The size, shape and placement is based on reference photos in my Jaguar restoration books.
I managed to make wire hinge pins for the rear windows. The hard part was drilling the matching holes in the body, as there is no clearance to use a pin vise and drill at the correct angle. Also, how would I get the window frames into place?
I trimmed the hinge pins so that they extend only about 1/16" or so. That way I can insert the bottom pin into its hole, swing the window frame into place and gently snap the upper pin into position. This was a tricky operation, because I had to make the pins short enough to allow for the "snap fit", yet long enough to extend into their holes and allow the window to pivot.
Next step: creating working swing-out latches to scale!!!
