Machined up the fittings for the ends of the forward pushrod of the popup tipup mechanism. Actually, Jo did the first one. Here he's putting a chamfer on the end.

After Jo headed out, I tapped the hole in the end and later machined a second one.

It'll use two cross-drilled rivets to hold the fitting into the end of the tube.

Just temporarily fitted together, but this is roughly what it'll look like.
