Building Wildings Tower Clock
« on: November 22, 2018, 03:26:36 PM »
Hiya,
Not posted in ages. Iíve been busy with work, the kids and my house and just to keep my workshop cravings alive, Iíve been messing around buying small Cowells lathes over the last year but not really getting stuck into a project. Well, all house jobs are done, the house work is done, winter is drawing in and Iíve managed to tidy my workshop and get focused. Iím now building Wildings Tower Clock and a little way through.

So here is my progress so far. I know there will be lots of errors and improvements and as always, I post for hints, tips and of course encouragement. So here is part one to four..... progress so far....

Thanks for watching!

Bad luck Chris - wheel cutting can be a real test of concentration. My worst one was when foolishly I responded to a ringing telephone - I should just have let it ring !

Yes, it was a killer. I felt sick and was storming around kicking things for a few minutes.

I was taking a video, run the cutter through the wheel, stopped the video, and spun the rotary table without withdrawing the cutter!! (Sure it didnít do the cutter much good either).

Easy answer is not to do videos but I enjoy logging it - its part of the fun so I just need to focus more. However, it is a lot of focus for 120 teeth!!

I was more than impressed with the repair job. It looks good and solid and turned out better than expected! Iím just going to intentially keep a bit of meat on the wheel and not cross out too high up to the rim.

Thanks chaps. Wish I hadn't been stupid enough to need to repair it but I am pleased with how it turned outs.
I'm onto the ratchet wheel now.

Which escarpment are you going to use?
When I built this clock I make the grasshopper . Its a  fiddle to make and get running but worth while the effort

BTDT

Nice fix:-)

Why is the gear so thick?  is it really carrying a significant load?

Sorry for missing the posts above...progress is slow as Iíve been busy with work.

Smiffy - now I know youíve built this clock Iím going to be picking your brains!!! Iím going for the grasshopper. Did you get it running ok and is it still running? Any pics?

BillTodd - yes, it has a significant load on it as it carryís the main weights.


Progress has been slow as I only managed a few evenings this last 7 days... but 8 cut the ratchet wheel:

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?

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 donít understand why this is needed?

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?

My Zeus gives no 54 as 1.4 and that is what I used . As far as I understand it, as a lantern pinion is only suitable to use as a driven gear the critic dimension is above the addendum so dimensions below the dedendum are less critical . I am not  a expert on gearing but that is how I understand it .
The other question about the click spring is to  lower  screw head so it can not catch and snag  on the line  .The same applies to the screw in the click
I used round head screws instead. This is mentioned in the book I have

Sorry sorry... I can get 1.3 or 1.5mm not 1.4!! You are obsolutrly correct,  54 gauge is 1.397mm
Iíve been to Ian Cobb who can source everything and he canít get 1.4mm...

So question back again. 1.3 or 1.5mm? I appreciate your mention about above the addendum being critical and I agree but isnít this a worry as that suggests the diameter is the critical bit?

I doubt if using either size would make much difference .By there very essence lantern pinons are more forgiving to a fairly wide tolerance range than a conventional gear.
