In April this past year I first wrote about the perforated or punched scroll-board on the Egerton tall clock (read about here). Since then I’ve been working on the details, trying to get patterns complete and finally decide how I plan to go about the work.
This weekend I began experimenting with a couple of different materials to see if one would be better than the other – I have yet to decide if this is the actual process I plan to use to punch my scroll. The first material was a scrap of the backed veneer I used for the clock’s door and base front (click here if you want to take another look).
I placed half of a paper pattern of the scroll onto my scrap and went to work. Each small cutout requires eight stabs, four using a carving gouge and four with my 1/8″ chisel. In the backed veneer, I needed a bit of force to push through. After a number of holes were punched, I took a look at the cutout area and decided this would work. The problem I have withthis material is that the veneer is crotch mahogany. Being crotch, the grain pattern is somewhat wrong for the scroll-board. In the original, the grain pattern is more straight, and it runs at an angle that directs your eye toward the top of the clock – one of the woodworking rules to which I like to adhere.
In order to use a piece of straighter-grained veneer, I had to turn to a paper-back veneer. First I had to see if it works; my primary concern is that the veneer, along the thin connector lines between the cutouts, splits and cracks. My second concern is using a paper-back veneer. I cut a piece of of material, laid the paper pattern on top and again went to work.
After working for about 30 minutes – yes, the work went quicker than I expected due to the material being thinner and because I developed a better routine – I peeled off the tape to take a look. You can see the results below.
I like the look and either material seems to work out, but I think I’ll pass on the paper-back veneer. This week I’ll make some pieces of shop-cut veneer just so I can get the grain right. And to provide support for those small connectors, I’ll add a cross-grain backer. I expect that the work will be more difficult due to the thicker veneer, but I’ll stay more true to the original and the look should be right-on.
Build Something Great!
