Arched-top Chests


One purpose for this blog is for me to show, and talk about, my woodworking projects. This year, I've been experimenting with arched-top chest designs - evolving towards one I'm happy with. Here are two chests that represent the pinnacle of this initiative (so far). 

This first chest is made from Canarywood. I like exotic hardwoods and luckily I have a local source for these woods. The arched top is made from 12 separate staves.






This second chest is made from New Guinea Paldao - another rare and exotic wood. Similar design but with only two drawers.





As you may tell, I've also become fixated on decorating my chests with brass tacks.

I've made arched top chests before, but I never had a dependable procedure for calculating and making the angled cuts necessary to fit the multi-piece tops together. I found an article in  one of my woodworking magazines that showed a technique using my table saw to cut the staves. I then did some calculations which led me to make a nice Excel spreadsheet to do the calculations for me. Now I can vary the number of staves and the extent of the arch to whatever suites me. I knew that Plane Geometry would come in handy some day!


Once I know the angles, I set them on the table saw, as exactly as I can, and cut the staves. This photo shows the technique for gluing the staves together and clamping them with a couple of bar clamps. I've evolved the weight I place on top from a jug of glue to a shooter's sandbag. The sandbag works much better.



For my next project, I'm thinking of making a larger arched-top design with more drawers - a sort of arched-top machinist chest. Can't decide on the wood, though. - sgb
