Building Wildings Tower Clock
smiffy:
It is over 10 years ago that I built the clock . I did get it running but never installed it anywhere due to moving house some 5 years ago .It has sat in a box since then waiting to be fitted somewhere .
The grasshopper requires very careful marking out and the pivot hole to pallet anchor face is critical , also the fitting of the pin and bushing holes for both arms to pivot on must be an exact fit . The adjusting screws could benefit from a small brass pad fitted to them as they are difficult to keep exactly in line with the grasshopper arms during adjustment .
To get the clock up and running again is on my to do list but watemills. vintage cars and numerous other projects seem to get in the way plus I have some 20 other clocks taking up space in the house

Cracking looking clock! I now know who to come to when I get stuck.
Did you cut your own bevel gears?

smiffy:
Yes I did cut the bevel gears , as they will only be very lightly loaded I cut them with a parallel tooth form using a conventional gear cutter .As the area of contact is small it works fine .
From memory I think the hardest gears to make were the lantern pinions . Initially I started by making them in one piece and drilling through from one end to insert the wire but this proved very difficult as the drill would wander on trying to start the hole in the second flange .
I eventually made a flange and center shaft with a second flange reamed to be a press fit onto the onto the center shaft . Both flanges were pre drilled before assembly.

Nice work.
Question for you; on the click spring, the plans say to reduce the thickness of the spoon end to about half. Why, I don’t understand why this is needed?
Chris
raynerd:
Second question.....For anyone who has built this clock or anyone with suggestions...the lantern pinions call for 54 gauge pivot wire. I can not buy this new. The only option I have is 1.3mm or 1.4mm. Marginally too small or too large. Anyone know a source of 54 gauge pivot steel or any thoughts on which you would go for...to big or small. My thought is smaller side to avoid binding?
