Greetings - Question on gluing bubinga

Hello everyone,

I'm a long time lurker to this board and would like to thank the contributers for all the great information in these pages. I have a question concerning a project I'm starting and would like to solicit feedback to help me out.

I appreciate that what I am doing may not be practical, but here goes... I want to change the headstock of an Ibanez SR506 to make it wider. In my opinion, the headstock is aesthetically unpleasing. At its widest point, it measures 3 inches. The fingerboard is 3.25 inches at its widest point. Being narrower than the fingerboard doesn't sit well with me visually. Additionally, the E, A, D, and G strings taper in towards the centerline from the nut to the tuning machines. Again, this just feels odd to me.

The head is 3+3 configuration. The sides of the headstock have a concave radius, tapered at the center and wider at the top and neck. I plan on plugging the tuning machine holes, then cutting the head from the neck end to the top along a tangent line to the narrowest part of the radius, then gluing wings to the head and reshaping to a form more pleasing to me. I will not be interfering with the head to neck joint area. The cut will result in creating a trapazoid shaped head.

The neck/head is wenga and bubinga. I will be plugguing the holes and adding the wings with bubinga (nicer wood than what's on the bass now).

1. What type of glue should I use for bubinga? I will prepare the surfaces by cleaning with acetone and a light sanding prior to gluing, but would like to know if Titebond (1, 2 or 3) is adequate for bubunga, or should I use something else?

2. I'd like to get others thoughts on the resulting strength of the reshaped head. The tuning machines for the A and D strings of the newly shaped head will end up entirely on the new bubinga wings.

I'm adding a new veneer to the top and plan on doing a bubinga inlay on the back so the plugged holes will not be an eyesore.

Thank you for your time in reading my post,

Bob
 
Widening the headstock... it can be done, just do it carefully. Make sure you remove all the finish before gluing up the wings and veneer, and clamp well... you won't want any gaps.

Strength-wise, the tuners should be fine on the wings. Once the glue has fully set, the glue joint will be stronger than the wood around it.
 
Original Titebond (#1) worked for me on bubinga-to-bubinga, bubinga-to-wenge, wenge-to-purpleheart, and ebony-to-wenge. As long as it's clean and not oily (and some including myself would suggest slightly raising the fibers with a once-over of fine grit sandpaper), it should work fine.
 
Thank you for your replies. I'll be cleaning and sanding the joint before gluing, and double checking everything before I make a costly pile of kindling.

This will be my first attempt at hacking a bass and have not worked with bubinga before. I really like the density and grain of this wood and how nicely it burnishes. I'm thinking the scraps from the bass mod will make nice fishing lures and bench plane handles :)
