R5's got new shoes..... (Feet motor's are fitted)

Reassembled internals on foot no1. Motor, belt, wheel, then into foot shell and locked in with the aluminium channel strip. I then fitted back onto R5's ankle.....


Ooops, I forgot that the securing ankle bolt needed to be cut short. It was that long to go through two pieces of 18mm thick wood!

Next problem I found. The gap between the side channels is slightly to wide and there (rightly so) is no flex of give in the metal channel plates. So the ankle bolt doesn't force the side channels to clamp onto the legs ankle. Again, the wood in the old internals did flex to clamp.

Lifting the body showed that the new foot is well balanced. But because the foot is not clamped I need a lock....an ankle lock. So out came the paper and pencil and traced up a wedge. Now because my foot shells are wood, the only place I can apply the wedge, in the hope it will work and not damage the shell, is on the inside face of the leg, so that the force is transferred to the metal motor frame directly below it.


And here it is, screwed in place. Let's hope this works......?

YES, it works! Well in lifting the foot and trying to tip it forward it stops it doing it.
Just have to see how well once fully operational.
And here are both new feet fitted, with there locking wedges.
