Here’s a crib I made a couple of years ago, it’s very similar to two other cribs that I’ve made. I don’t particularly like working with Hickory, but it looks pretty good so long as you are going for wild color changes.
One thing I thought you fellow LumberJocks might be interested in is the Jig I made to cut giant circles (16’ diameter)
It’s a pretty simple jig, I had one of my friends CNC some 1/2” polycarbonate base plates for the router end and the pin (which sets the center of the circle). Then I connected the two pieces with some T-Nuts and an 8’ piece of 80/20 extruded aluminum T-Slot stock. The beauty of the 80/20 is that it provide an infinitely adjustable radius.
I’ve used it on a number of projects and it really is a great jig to have around. With a good solid carbide spiral bit, it cuts perfect arcs, every time. I just do a quick touch up with sandpaper and it’s good to go.

Nice jig, but I’d worry about the pin coming out since it doesn’t seem to be secured. I’d have used some sort of lock on the pin.

The Pin really hasn’t been much of a concern at all, it’s buried about an inch deep in an interference fit hole in the wood (really snug) and the in the polycarbonate is also really tight. The biggest thing going for it, is there really isn’t any non-shear forces in the setup.
That said, I’m sure it wouldn’t hurt, it’s just not really necessary.

Whoa, so when are you building that giant 16’ round table for King Arthur and his doods? ;) Nice crib :)

I so like this jig & it’s simple construction. I have made arcs before & used an MDF contraption I’ve made in a hurry. It worked but this looks like a treasure & I need one as I have a project I am about to start. You lead the way…
BTW the cribs look ace as well

Nice crib and a pretty serious looking and large circle cutting jig! You have also got a pretty good looking workbench.

The crib looks great, i like the color variation. That’s a serious circle cutting jig :)

Damn, fits on that bench! Two good ideas, but no space for such a long bench to get the arc. Thanks for sharing
