Following on from Phil's question about door repair, I thought it might
be interesting to try DIYing a jig to do accurate inlay work with a
router - either for the original purpose of repair to a surface, or for
decorative work using contrasting materials.
Here is how it went:
Amazing dedication John, above and beyond the call or duty. I think you might put Trend out of business (at least for their 50 quid template kit)!
I'll have to read it a couple more times tomorrow!
Part of the attraction was seeing how good it would be for decorative
work, or doing variations on things like bow-tie inserts used for
stabilising cracks in timber.
I has scope, but one of the main limitations for fine work is the
minimum radius of the inner curves.
If one got a smaller bush, and a finer cutter, then you could do more
detailed templates. (although you would probably need to hog out the
rest of the rebate with a larger cutter, just to avoid tedium).
(Still not going to match what you can do with a CNC setup though)

You know about the "Shaper Origin Handheld CNC router"?
One sticks a coded tape on the workpiece, a camera uses this to locate the
cutter head in space. One moves the router frame, by hand, along the path given
on the screen. All the inaccuracies and squiggles are adjusted for, as the
cutter head is moved within the frame by servos. Get too far away from the
programmed path and the cutter goes up...
There's also some sort of speedometer to show the feed rate (which you
programmed along with the shape).
It conceived for things which can't be put in fixed CNC machines, like floors.
Horrendously expensive ($2500), but they offer them to maker labs at cost to get
the feedback, and to profit by what the geeks think of as they play.
Alternatively: a sharp chisel, cut out a diamond shape with a mild taper, fit
plane-tapered plug by hand. (I know people that can pull that off and make it
look easy. One trick is to compress the plug lightly with hammer taps, so it
swells into place at the surface, once the glue moistens the wood...)
Yup I have seen them... I can see the attraction for some jobs, but not
sure if I would go for one over a fixed CNC table style setup.
(although the reduced space to setup and use would be a big win in many
Indeed - and inlay work on existing fitted woodwork would be a good use
Yup, hand work will do things (corners basically!) that are hard to
replicate with a CNC setup... for fine furniture making that's fine. The
router inlay kind of level is more applicable for "building" level work
