In an attempt to cut a large radius nosing for some mantels I’m making, I’m in process of making a router trammel to support the bit in a constant arc. Made from 3/4 ply, my inspiration is based off an old Fine Woodworking article and tablesaw trunions. I still need to mount it to a stable base, fit a router and bit and the fire it up…
I’ll post more when I make some sawdust.

That is much, much simpler than what I was thinking! Looks like it will work great!

What a great solution. I’ll have to file this one.

Hi Tom,
That looks like an interesting jig. I need to do something similar both with some molding around the hearth to hid a 1/2 gap where the flooring and masonry meet and a mantle (that I promised several Christmases ago).

Good jobTom!
Ingenuity is mandatory when working wood.
You has it!

That should work. Necessity is the mother of invention.

Looks like you just need a 1 1/2 bottom flattening bit and you’re ready to go.

Yeah, I remember that article in FWW. A simple elegant answer to NOT having a shaper/moulder. Show us some sawdust flying next time.
always,

tom, that profile is pretty close to that of log cabin siding. our camp is sided with something very similar to that but of course one of the laps is reversed, unfortunately the mill discontinued that style years ago. others still do make a thicker version, how ever. I would ASSUME that the profile would be done in multiple passes, so if you could find a mill that does that siding, you might be able to put the face profile on something else for you

That’s pretty cool, Tom. How did it work out?

Thanks for askig Steve. It worked out well enough to complete the job, but it was slow going… I can’t complain though, it would have cost me an arm & a leg to have knives made and mouldings cut. If you want to see it work, check out this video I uploaded a while ago… http://lumberjocks.com/jocks/naperville/blog/4105
