Grant When finishing the top did you mask the bridge area (and with what), or did you finish over it and then scrape it away for gluing? I would have thought that oil finishes would penetrate more than nitro or polyurethane and then it would be hard to get back to the unfinished wood. However, if yo...

There is a lot of love and wisdom in that post, Taffy. Thanks for sharing the stories and the pictures. I will happily "waste" some more of my time looking at the video if you are able to post it (maybe on You-tube).

Cocobolo makes me cry! Yes, because it is beautiful, but also because I got some dust in my eye last week and I had raccoon eyes for 7 days. Needed steroid drops to get it to settle down. I used it last year without any problems but the sensitivity can develop late - so take care. But those sides ar...

That is an exceptional guitar Grant. Classic clean look and very fine work. Can you tell me how you got that high gloss with an oil finish? How many coats after the Z-poxy, and what did you do to buff it?
Congratulations

Very stylish, Dave. The headstock is beautiful from every side - veneers, binding, volute all combine really well.

Thanks for the comments on the bracing, Allen. That makes sense. I am keeping your bracing pictures as a reference to work off for my own. You are right that I certainly will err on the side of stronger bracing after the experience of my last guitar (but it seems to be doing OK for now with the Brid...

Allen, Bob I have been following this thread with interest because my current project is a 13-fret version of the Nick Lucas style L-00. I have a plan for a 14-fret L-00, so there will be a similar issue to your 14-to-12 fret conversion. My understanding from some technical descriptions elsewhere is...

Most "new" ideas are just borrowed. Even if you don't have a broken bicycle lying around you can buy inner tubes from K-Mart for less than $5. Allen, those are the Golden Age tuners from Stew-Mac. I haven't finished the guitar yet so I haven't put them to the test under string tension. They look goo...

bicycle inner tube clamping for fingerboard gluing

On saturday the workshop became a bike repair shop because my son decided to pull his old bike out from under the house and get it going again. Both tyres were flat and one had multiple punctures so we put a new tube in it. After a bit of work on the gears and brakes it was good to go. Next day I go...

I had to Google "dado blades" before I got it, but that seems a great system. A table saw is on my wish list (and my birthday next month :wink: ) so I am keen to learn about cool things I might be able to do. While I am thinking about it - what advice can you all give me about choosing a table saw?

cutting slots in bridge pins

I got a set of buffalo horn bridge pins from LMI. Very nice, but they don't have any slots for the strings to run in. I like slots in my bridge pins so I decided to cut some. You can buy a special jig for this task from Stew-Mac or LMI if you want to part with $US63.48. Basically all you need is som...

I was using a white chinagraph pencil, which leaves good marks but it is hard to get to a fine point, and they are expensive. Since Allen's tutorial I have used the scalpel and chalk trick - very happy.

Hi Robbie
Nice video, as always. The 360 degree rotating clamp system looks very useful. Where would I get one, and at what cost. I can see that they would be very worthwhile in a busy workshop, but I am a one-man weekend hobby builder.

cheers

Make a clear perspex template. It only needs to be the size of half the soundboard (down the long axis). Like Dom said, then you can see the grain through the template which helps to decide where to cut. Drill holes through the template at the points corresponding to ends of each brace so that you c...

I am sure you are all correct. I made a big mistake scalloping the X-braces in front of the X. Looking back at the plans I was following there is not supposed to be any scalloping there, as you all identified.

OK, I live and learn! It is likely that I have made some serious errors in the bracing. Another factor I just thought of is humidity. When I glued the box together, and also when I did the set-up, the humidity was around 40%. Last week when things started to go pear-shaped we had a lot of rain in Sy...

Need some advice - structural problem with my first guitar?

I was pretty proud of myself when I posted the pictures of our first guitar 2 weeks ago - but now I am a bit worried. It seems like the top and neck angle are not holding up so well to the string tension. The main symptom is rising action, and pretty horrible intonation. When I did the initial neck ...
