Here's another take on these for binding routing. Got it off kitguitarbuilders site.

Nice! The contact area between the bottom of the base and the guitar's top or bottom seems fairly large. I can see that some wood is removed from part of the base, but is the remaining contact area small enough not to affect the angle of the cutter, thereby the rabbet angle?

This looks very similar to the one Jim Williams shows in his book .

I built one with the same principal ,except mine has two bearings to run along the sides , and a much smaller footprint (donut ) .I've also included a micro adjustment for hieght and depth. My donut is also adjustable via shims ,to suit either the back or top radius'

Looks like it's from th UK, Trend T3 trimmer and one of Axminster's bits of kit behind it. I just love Axminster 'white' goods.

I didn't make this myself. I pinched the pics from some builders blog that I found at kitguitarbuilders.com. He's using a big full sized router, hence the rather large base. I may try making something like this scaled down to my Ridgid trim router. I really like the way the handle is integrated into the design. Looks like would make for a firm, sturdy, steady contact to the sides.

Chris, it looks like it would work well although i'd find a way to incorporate bearings that would index the sides. Other than that, i find it 's a pretty cool jig that would be sturdy by a firm handgrip.

Serge,

The guy who made this said he uses some sort of 'slippery tape' on that indexing edge. Maybe teflon tape?

Somewhere else I saw where someone used 1/2 of a door hinge with bearings mounted on a pin. I might try that if I can find the right size bearings to fit a hinge pin.

Chris, its probably something like slick strips.

Lillian,

Thanks!! That looks like just the ticket, and will save alot of work over trying to fit up bearings. Slick strips look good for lots of uses. I'm ordering some now.

The distance from the cutter to his thumb is pretty scary to me. No thanks.

nice work.....yes i agree with the above ...i have made and used a jig like this before and ended up cutting out most of the contact area except for 5-10mm at the top and bottom because it wasn't so smooth to use and if the sides arn't real straight all that contact area isn't very forgiving . but it did the job...Ended up building one with bearings though because it just feels a lot smoother to use.

Chris, i just thought of something, how about adding a narrow piece of UHMW plastic, that would be slippery too.

One question, is this jig adjustable for binding width, by retracting the handle from the wooden base under the router?

I agree with Rodger. If this is a jig you would like to build, please consider putting something between your thumb/fingers. Sorry, its a mommy thing. Ryan is still nursing his fingers back to normal after being incredibly stupid (and just as lucky) around the table saw. They can't sew up hamburger.
