Yew Clock (PIC)

>Hi there,

Below is a picture of a Yew Clock with African Paduck Inserts I turned a few weeks ago. It is about 8" in diameter.


I fastened the Paduck inserts in with PVA wood glue. They were an extremely good fit, but weren't forced in.

A few weeks later when I took the clock off the wall to have a look. I noticed there were small hairline cracks around the insets. They are so small you have to have ilook closely to see them. I assume this is from the two different woods having slightly different expansion coefficients for moisture and/or thermal effects.

If anybody has made anything similar do you have any tips for avoiding this? Should I have used a more flexible glue such a silicone, and made the fit a bit more "sloppy"? Thanks in advance for any tips, or critiques on the work.

>Hi David,

Lovely piece of wood, and very nice finish.

Does the number of dots mean that you always feel there are only four hours in your day as well?

>Hi Tom,

Thanks for your comments.

You mean you get four hours.. it doesn't even seem like four minutes sometimes :o)

>Hi David,

Very nice clock, yew is one of my favorites, it has so much character.

There was an article in the woodturning magazine from he UK where this guy made a dish of some very light wood and placed small circles evenly around the edge , one of each different tyoe of wood. Kind of like a tray showing wood samples. I was going to mak one like this but like a clock, similar to yours. I was going to try for four markers because I think it wouldn't work well with 12. To make a long story short, he ,made the wood pieces like buttons seperately on the side not the end grain and then glued them on the wood, with silicone I think. This appears to allow for different wood shrinkage/expansion rate.

>Hi Ron,

Thanks for the tip on the grain alignment and glueing there. I will try that with the next one.

Like you I think 12 might look too busy. I did wonder if using smaller ones for the other hours might help. The other thing putting me off is my lathe doesn't have a proper indexing facilty. So getting them all spot on without problems was a bit dodgy :o)

Thanks again

nice clock. I have one on my web site under projects. I surrounded the dots with brass and have had no problems with expansion or contraction. By the way, if you set the clock hands one on top of the other and mark the point, then turn the hands one revolution until the minute hand hits the point, the hour hand is at one. Continue a revolution and the hour hand is at two and so on. Makes it easy to accurately mark the points for drilling.

>Hi Darrell,

Thanks,you clock is very nice too that Maple is super. Your idea with the brass tubing is a nice touch too. I suspect some of my problems could be down to using Yew, it does seem to surface check easily. Fortunatly while its on the wall they can't be seen :o).

Great tip on how to mark the hours out with the clock, and excellent website overall. I had a good look round. I coudn't have done it the way you suggest just down to my mounting method and order of doing things. I will conisder trying the next one in a similar order to the way you did it, then I'll be able to use that way for marking them.

Thanks again

David
