whalehazard Posted November 15, 2010 Report Share Posted November 15, 2010 So I miscalculated my headstock angle. How much is too much? I know the scarf joint is good...what are the consequences if I use it as is? Quote Link to comment Share on other sites More sharing options...

MiKro Posted November 15, 2010 Report Share Posted November 15, 2010 So I miscalculated my headstock angle. How much is too much? I know the scarf joint is good...what are the consequences if I use it as is? Most Headstock angles range from 10 to 15 degrees. But if you look at a Lute from 100s of years ago they go from 70 to 89 degrees. So what works? That's a good question Quote Link to comment Share on other sites More sharing options...
verhoevenc Posted November 15, 2010 Report Share Posted November 15, 2010 Lutes don't use a scarf though. At those angles a scarf would just be gluing to endgrain and would not work IMO. I wouldn't go too far over 15 degrees... perhaps 18? I'm just thinking surface areas here as my rational. Chris Quote Link to comment Share on other sites More sharing options...
whalehazard Posted November 16, 2010 Author Report Share Posted November 16, 2010 It measures a whopping 26 degrees. I know this is far beyond the recommended maximum of 17 or 18, but is a good scarf joint at 26 really any weaker than a one piece neck that's cut across the grain at 17 degrees?

verhoevenc Posted November 16, 2010 Report Share Posted November 16, 2010 Oh man... that's pretty hefty! I wouldn't build with that. I haven't sad around and done the trig to figure out what the glue surface length on that would be... but I'm seeing in my head something minimal. Also, the higher the angle, the closer to end grain your glue surface gets. If you MUST build with it... please please please headplate and backstrap it (if the scarf is in the head and not the neck at least...). Here's how in case you were wondering: Chris Quote Link to comment Share on other sites More sharing options...
