I did say that things would slow down!
This stage, for me, has been the most difficult so far. The books I’m following recommended gluing the purfling to the binding before bending them together on the bending iron. I found that to be disastrous, I (or the wood) suffered splitting, delamination of the black, white, black purfling and twisting. Oh what a mess! So I went back to what I’d thought would be the easiest before I read the books! Bend ‘em separately!
First picture shows the steps being cut with the router. I taped some very fine ‘wedges’ on the router base to account for the rounding of the guitar’s top and bottom. The angle varies around the perimeter so I took an average (sort of).
And then I realised too late that there was some ‘slogger’ in the router base set-up, so the depth of the channel varied more that it should. I could rout out the back bindings and re-do it all, but it’s at the back & Mrs YS suggests I move on and use it as a lesson for my next one!



I cut an old push-bike inner tube round and round to produce some very handy rubber strip that worked admirably to ‘clamp’ whilst gluing.

Couldn’t wait to attack it all with the card scraper…

It’s nice having a Mrs around sometimes to tell us to chill out.
Other times, not so much.
Good call this time although.
The purfling part has always baffled me. “How the heck do they do that?” It seems like bending before laminating makes a bunch of sense. Looks good from here.

anyone that even tries to build a guitar impresses me. I look at it as something beyond woodworking.

Stewart: I’ve used the old inner tube trick before. I’ve used car tubes and truck tubes that I got from a tire repair shop. Where they replaced some blown out tubes. (why they kept the old ones, baffle me).
Nice job with the bicycle tubes.

I can still smell the rubber on my hands even after a shower and several hand-scrubs!
Joe – When I last pedalled into town I suffered a rear wheel blow-out; invested in new tyres and tubes, and [Karson] kept the old tubes ‘just in case’.
Steve yes, I’ll retain that flaw and, in the Muslim tradition (I think) tell folks that it’s deliberate as only The Almighty can attain perfection.
Don – Did you get out on the motor cycle this year? Our Honda ST1100 has hardly turned a wheel.

I’ll bet I didn’t put 300 miles on it. Its a shame, between work, travel and other things, there just wasn’t time left.

It’s no easier in so-called retirement Don. There was a time we found opportunities for extended trips into mainland Europe. This year, I rode it for its annual service & very little else. Must try harder in 2013!

Not sure how many guitars you plan on making Stewart so it might not be a worthwhile investment, but you can buy a device for a trim router that automatically adjusts for the varying arches in the top and back. I remembered reading about this gadget a few years ago when you mentioned your issue. It is made by LMI (Luthier’s Music Supplies) and is called the Ribbecke Binding Machine. Not sure if it is still available.
Knowing you, you’ll probably fashion something better from an old tin can anyway :o)
P.S. Here’s a decent article about Binding and Purfling Tips.

Cool build, Stewart. I’m doing one myself and haven’t decided yet how I will approach it. I kinda like this method, however…

Looking forward to more!

Thanks Jay and Andy. I’ve had a good look at both of those approaches and I’m sure I can knock up my version of either one or t’other should I decide to make more (which is highly likely). I do have at least two rather nice sets of soundboards, backs and sides to use up! I can’t quite make out what the Kenneth Michael shuttle is all about yet.
Having said that, the bindings I did on the front of the guitar turned out much better than the back after I Stiffened up the rig I was using, by jamming a piece of wood between the wobbly bits!
