Question for the Clockmakers

[Jediscroller]

Hi All,
I want to get to building a clock plan I have. I'm curious as to what size to drill the hole for mounting the movement. The information that I could find on the movement I want to use indicates a 5/16 diameter shaft. Is this the size of the hole I need to drill (or do I drill it at 11/32 or 3/8) for a fit for the shaft.
The movement is #2549 in the Wildwood Designs catalogue.
Thanks in advance for any help you could provide.

Very slightly bigger hole than the diameter of the shaft works good. Test hole size with a couple size drill bits in a scrap of wood before drilling clock.

5/16 is the size of the hole to be drilled. You can go up to the next size if you have it. You do not want to drill too large because then the motor will not be centered on the clock face. That is a good mottor I use it alot in my clocks. The other factor to concider is the size of the material of the face of the clock. Match that to the correct shaft length. Do not know what clock plan you are using but be careful on the length of the rod and the size of the BOB no not you Bob D. Because too big and it will hit the sides of the clock. Good luck and post a photo when completed.

yes,i would go 1/32 over the size of the shaft,somtimes a bit of finish is enough in that hole to give you a headache.

Thanks folks. I didn't realize that I didn't put the name of the clock in my post, it's the Williamsburg Wall Clock (also from Wildwood). I want to get to cutting it even though I haven't ordered the clock works yet. Looks pretty easy to do, I just have to decide on what woods I'm using (I'm leaning toward maple and walnut).

Nice choice of clock and the choice of wood is a great contrast and looks good together. I would just caution you that maple can be a little tough to cut if you do not use the right blades. It can have a tendency to burn on turns if you are a person that likes to spin the wood in corners. Oak and walnut is a great combination also. Anyway good luck with it and it would be nice to see some photos not only of the completed project but maybe also a few as in progress photos.
