Clock With Laminations and Segments

[William Young]

This was an experiment with using laminations and segments in one turning project. Notice that the segmented ring is off center from the laminated backer. It seems no matter how hard I try to be accurate when centering something like this I almost always see discrepencies like this. ArRrGgg . .
Does anyone have any secrets to share about getting parts to line up properly on something like this ? I thought it was very close when I was clamping but once the glue was dry and I was into turning it was too late . . of course. I was watching for a while after glueing to see if the ring had crept from where I thought it should be but didn't notice any movement
I am going to put this one on my own kitchen wall as a constant reminder that I have to do much better getting segmemted rings lined up with one another or getting segmented rings lining up with a laminated base.

BTW. As picture sizes are deceiving on websites, I suppose this could be considered a large clock. It is slightly over 13.5 inch diameter.

New Glasses maybe????

Seriously though nice work anyway. Not knowing all the procedures you did or what is involved I will mention a few things. First when I do overlays or things that need exactness such as this I first do a dry run and when I have things looking like they should I put some witness marks on the edges so when I go to glue up for good I just line up the marks and do not have to worry about that part. Second when I glue something like that down and requires a weight on top for clamping purposes or even if I use clamps I use my yellow carpenters glue and in a couple places I use a couple small dabs of 5 minute epoxy . The epoxy holds the piece in place so when I clamp or put the weight on it does not shift on me. Not sure if that would be of any help but it might help others for doing overlay work. One oher thing and I am sure you did this but the exactness of the pieces is critical.

Nice looking, I've not tried anything like that yet so this is just an observation. I think that if you had used the off-while (yellow) in the ring over the whole brown section and the brown over the whole yellowish it would be more eye catching. Either that or maybe just a very narrow band of the base color right in the center of the overlay.

Good point Tim;
I had actually thought of that when cutting the segments and then I couldn't get my mind around how I would add the small white segments . Same problem would occur if I alternated brown and white small ones and they would wind up being in the wrong place.. If I had left out the tiny white segments altogether and just alternated the large brown and white ones and placed them as you suggested I do think it would have looked better.
It was a good practice and learning piece. Best part I like about turning is that it only takes about an hour to make something like that after the glue-up is finished and even the glue-up is mostly waiting time for the Titebond 11 glue to cure
Oh . . just for the record . . that is very white aspen wood but my picture taking is lousy so it looks yellow. I sprayed it with water clear WB lacquer to maintain the whiteness.
The contrasting wood in the laminations is cherry and the segmented ring is cedar and aspen .
Good way to use up a bunch of scraps that otherwise might have got burnt in the wood heater.

John;
Need glassess maybe ? ? ?

There may be more truth in that than you realized when you typed it. A couple days ago I had my eyes examined for the second time in three months at $95.00 a pop plus $300.00 for the glasses. It turns out I have macular degeneration in one eye that cannot be corrected with glasses and is age related and inoperable.
I am waiting for a call from an octomologist to make an appointment but the way our Canadian Government has screwed up the health system in recent years that may take many months to get an appointment if at all before summer or fall.
I thought the bad hips and shoulders that may need replacement was bad enough but now this.
Oh . . these wonderfull golden years.

From my own use of one I wouldn't take nothing for my Delta Cad drawing program that I have. With it laying out a circle, then splitting it into 8 equal parts wouldn't be not problem. It will even give you the angle that each piece would need to be cut on to make them all fit together. I think every computer should come with a CAD program on board.
