Starting with the carriage lock parts.

On the front end, the washer, spring, wedge, cam, collar followed by the handle. Note the collar orientation. The 'anti-rotation' hole will face the casting, not the handle. Yes I did it wrong the first time! Note also the cam orientation. The camming end faces the handle. Finally the wedge small end faces inward.

A 'secret' that helps align the holes for the tension pin. All that stuff is under spring tension.

The handle will index to the cam in two positions. The collar anti-rotation hole will be at the top, so the handle 'top' must face the same.

Finally the rear washer, spring, wedge, added washer and locknut. I added the washer since the nut had worn into the softer wedge. Wedge small end again facing in.

The collar is registered to a tension pin in the carriage. This pin will hold the entire carriage lock mechanism in place when the way tubes are not present.
It must be forced onto the pin. Applying pressure to the locknut at the rear will force the collar off the pin (locknut need not be removed first).

Ready to lock to the way tubes.

All the table height control stuff.

The axle is inserted through the pinion with the retaining clip end outboard and the pinion large end facing outward.

The axle projects through the front and the other pinion again with the wide end facing outwards.

The crank slips on after a washer. This washer is too big(id) and I will be replacing it with a better fitting one.

A washer next.

Followed by the lock knob.

I decided to place the spacing rod jam nut on the inside of the casting. he nut has a 'good' side with a flat ring shaped surface that should face the casting.
