Thread: First time clock case seeking suggestions

Hi Ian

That's a very nice looking clock, simple lines and very attractive.

Sorry, I don't have the answer to your question, but I do have a question about the movement you've used. I have ambition to build something similar to your clock but have no idea about suitable movements. Any advice please?

Cheers
Geoff

Try this link. Clock Movement Importers Pty Ltd
Ihave just about completed their plan 933 and used a Hermles movement in it.
I have no affiliation with the company at all, other than buying the plan and movement.
I have spoken to them numerous times and have been very pleased with the interaction.

Ian, I like your design and the open-ness it has to allow the clock to be seen.

The movement looks like the one I am using. Question does the weights in yours have enough length to give you the time between windings? eg 8 day.

Thanks, Geoff. The movement is the Hermle Delux Vienna Regulator from Lets Make Time, with the second hand and the plainer face without the inner gold ring. Look forward to seeing the results when the ambition is realised.

Regards
Ian

Thanks, Lyle. I ran the clock for a few weeks mounted on a dummy backboard, so that I could work out the dimensions for the case. Since I'd be sure to get confused if I try to wind it every eight days, I settled for winding it on the same day each week. With 7 day winding intervals, the weight descend to a point about 30mm clear of the bottom of the case. Interestingly, the quality and volume of the sound of the chimes is different on the veneered plywood backboard to what it was on the dummy backboard which was a solid piece of pine. Compared to the solid pine, the plywood backboard seems to resonate some of the higher frequencies, and the chime sounds louder when you are in rooms other than the room where the clock is.

Thanks also for the CMI lead. I'll get one of their brass knob/latches and see how it looks.

Ian

Ooooh! That is a nice looking clock, Dealbata! I have an old Vienna movement myself (that I picked up on e-Bay) that I want to eventually build a case for. I like the simple lines of the Biedermeier style, but my movement comes from the later more ornate style (1895) so I am undecided whether I should go Biedermeier or more ornate.

Tell me. your clock has three key winding holes, two weights but only one pulley and weight line. Is it spring driven or weight driven or some sort of hybrid? Is it a Westminster Chime or just a time and Strike (with a dummy winding hole?)

cheers

Hi Walesey, the three winding holes are all operative. The two outer ones wind springs that operate the chimes (Westminster), while the central one raises the weights for the clock mechanism. The two weights both hang on the single cable suspended pulley.

OK. That is interesting. Springs as well as weights. I have always liked weight driven clocks, rather than springs, but there must be advantages to having springs, otherwise they would not be so common. I understand that weight driven clocks keep better time. Is it a "Deadbeat" or a "Recoil" type escapement?

regards
Walesey

You got me there, Walesey. But thanks to the wonders of the internet and five minutes googling, I'm fairly sure it's a deadbeat escapement - main reasons being that it's a modern movement and there is no discernible backward movement of the second hand each cycle of the pendulum. I'll check the shape of the pallets next time the movement is out of the clock as the two types of escapement appear to have quite differently shaped pallets.

As to the advantage of a spring driven movement, the only one I can see is that it allows for much smaller clocks, and if the pendulum is replaced by a balance wheel, then it allows for a clock that works in any orientation.

Probably a bit late, but what about two rare earth magnets buried in the door frame and the case, with thin plugs glued over the top?

Thanks for that suggestion, Graemet. I'll keep it in mind for future applications, jewellery boxes or something like that.
