So, first things first. First, this happened:
I was just spinning along, when I suddenly stopped because the right footman connector spontaneously broke in two places. You can see that it is not connected above or below the part that rocks back and forth. I don't know what it's called. If I had a manual or a diagram, I would know. But I don't.
Next, I ordered the replacement parts and one tool. I purchased the pieces pre-cut, but I did find other places that offered one long piece that you can cut yourself. I also ordered the square screwdriver I needed for the Lendrum screws. Rumor has it that earlier wheels had Philips head screws, so take a look at your wheel before you buy the screwdriver.

|Screw in the back of the rocker-thingie|
First step of the actual repair: I took out all of the screws, keeping track of where they go back. Once the screws were removed the footman connectors were a little tight in spots, but they pulled right out. Even though the left one didn't break, I replaced it anyway. Seemed like a good idea.
|Old connectors vs. new connectors. If your connectors look like the set on the left, you should buy a new set so you have it when one breaks. They do age.|
Second step: I re-installed the left connector, pushing it in as far as it would go into the rocker-thingie above, and flush with the bottom of the treadle below. Re-installing the treadle screw was pretty straight-forward, but I really had to push on the screw in the rocker-thingie. The screw goes straight into the connector, with no threaded guide, so you have to push a bit while twisting to get it to go in.
|Can you see this? The connector is Right. There. and you gotta make the screw go through it. PUSH! CAREFULLY!|
Now, I had to guess on how to install the right connector. It connects with screws at the treadle, the rocker-thingie, and the footman. The question becomes where to secure the rocker-thingie. What I did was to line up the left and right treadles and adjust the rocker-thingie to be parallel to the floor, and secured it there with the screw.
|Shadow makes it look a little off, but I think it is straight.|
Last step! (One reminder: if you moved the drive band out of the way, or if it moved itself, be sure it's back where it needs to be before you secure the last screw, or else you'll have to remove the c clamp to put it back on.) At first I pushed the connector all the way into the footman, but then the footman was too close to the rocker-thingie to move as far as it needed, so I backed it out a bit and looked at a few other wheels on the internet to see how they looked. This looked about right, so I installed the last screw, and gave it a little whirl.
I hope this is helpful to someone. If you have a schematic or diagram of the Lendrum Original, please share. At least tell me what the rocker-thingie is and I'll edit the post with the correct terminology.
