Colin,
What are the dozen or so small holes drilled radially half way along the shaft ? I did wonder if they were related to the indexing of the gear teeth but although it is hard to see, I think there are less holes than teeth so not that.

Spot on David, they were for indexing. I was going to machine them off but as it made no difference I thought I would just leave them there. All the other gears had them too but needed to be machined off.
Colin!

Not to hijack your thread, but his name is NED! , Cheers Andrew.

Well, that’s two of your crew accounted for now, Colin.

Should post boxes have a thread of their own ?

Andrew, is that in Aussie Ned or a Kiwi Ned.
David, any suggestions for the third.

Back to the serious stuff I have completed the centre shafts that hold the bearings for the gears. I have changed the design as the original is very complicated and from what I can see is unnecessary. The material used is the same as the gears but I won't be getting them hardened as they don't move at all.

Each shaft is held in place by the recess top and bottom and there is no way they can move whereas the original is held in place by a wedge bracket and bolt. The last photo shows the heavy plate/bracket which needs to be bolted down to the underside with a series of bolts. Very strong once completed.
