- The 85th episode of the guitar builders basics video podcast from Ben at www.crimsonguit... where Ben answers viewers questions on all things luthiery.
In this episode Ben talks about gluing an acrylic or perspex headstock to a wood guitar neck. Building Goldfrapps Charlie Jones acrylic bass threw up the question of how to glue acrylic or perspex to wood and a viewers asked how it was done.
Greetings from Seattle Ben, thank you for all you do to help keep our instruments in tip top shape. I have learned a and will continue to do so. I've been doing repairs for the past 7 years and have decided to finally build a guitar to my specs. I'll be ordering some tools from you wonderful company. So please keep up the great work you do.
Some of the guys at the local club were talking about things they used to polish plastics. They mentioned some very good, but expensive products. I was using plastic polish and switched to swirl mark remover for auto paint and have been happy with it, but wondered about the possibility of using other things. As such, I went home and pulled out a can of beeswax I have from toilet base seal rings and mixed some with pumice, some with rottenstone and some with diatomaceous earth. Each was a winner.
I stopped sanding at 320, went to the pumice, then the rottenstone and got great results.
Just sayin.
What a great shop you have just amazing
I used Bostik contact glue to attach acrylic into a headstock. Still holds after 20 years, and glue joint is not visible. Easy to work with. Of course, that was not transparent acrylic but black, because the glue was that brown stuff.
thank you again. love the hat neat
Can you do a video on defeating and making a lined frettless neck
I've been thinking about making a jazz bass with a lined frettless pbass neck
By the why that's a badass hat
Way back when I worked at -Big Evil- Guitar Center (some 17 years back), BC Rich did a run of acrylic guitars: they had acrylic bodies, wooden necks and acrylic headstocks scarf-jointed on. Those headstocks often broke off in transit, and it was so common that we got to the point that we'd just assumed about half of them would probably have to be shipped back (in fact it was probably a lot more than that; I wasn't responsible for shipping/receiving, so I didn't have to deal with that aspect.) We'd open shipping cartons and a bunch of headstocks would be sliding around at the bottom of their boxes. I have no idea what type of adhesive they were using, but it absolutely was the glue itself that failed: the joints were always clean and smooth, rarely any broken bits of wood that are common on broken wooden headstocks. At some point BC Rich did away with the acrylic headstocks entirely (no doubt after losing a bunch of money) and went back to all-wood necks with acrylic bodies.
I don't think it's necessarily a great idea to try and joint two dissimilar materials in such a high-stress/high-tension area, especially something like acrylic that doesn't always play nice with a lot of glues. If someone was inclined to give it a go, I'd suggest building some mockup necks, putting tuners and strings on and testing various glues before committing to one for the actual instrument. It should be pretty apparent, pretty quickly, which glues have potential and which ones will easily fail. I think part of the problem with the BC Richs that I remember was that they were budget instruments and the factory probably didn't put a whole lot of thought into adhesives; still, acrylic can be difficult to securely glue to other materials (especially when it's under a couple hundred pounds of string tension), so I don't think it was entirely BC Rich's fault per say.
I've been using 2:1 epoxy to sandwich acrylics and getting good and bad results. After lamination, I toss items on my lathe and turn them. Some blow apart, so I roughed both the wood and plastic up and took another stab at it. I'm paying attention to the type of wood it happens with, which may be the more dense (fine pore) ones. I will also look into the oils in the wood and if wiping down with lacquer alters the end result.

Anyway, looking for glue ideas too.
Perspex is a brand name, acrylic is a type of plastic. It's like saying coca-cola (brand) or cola (generic type of drink). great video btw
After seeing the acrylic tuning keys in this video I wonder what do you think about making your own keys out of wood? Do you think it's worth it? How would someone go about making them? Thank you!
Would putting some graphite rods, in the neck of the bass. Fix the problem with it flexing and bowing to much?
Hey Ben,
the problem of the bass was the acrylic wasnt strong enough to be used as a neck material, what about if it was a maple neck with acrylic fretboard?
How stable is a acrylic guitar neck?
Hey Ben,
To slant or not to slant pickups on a multi scale guitar?
where i can find an acrilic necktrough guitar like this bass and how much for it? thanks
why not just rout the neck wide enough from behind to put a second truss rod in?? i bet you are more than capable of that! the neck would be more stable and would be all perspex! and by that i mean rout the truss rod channel again.
Hey Ben, What was wrong with that all acrylic bass? It seems like there is still potential in that concept, especially since it looks so cool!
In a recent podcast he shows what's wrong, the neck bends quite a bit :)
Any chance you know which one it was? I've seen them all, but I guess sometimes things go in one ear and out the other.
Yeah, it was "Why do we still use wood in guitars? Podcast 78"
I guess that would have been a good place to start, huh? Thank you, sir!
I'd like to know why one never pulls a file backwards. not as accurate or other reason?
File teeth only cut in one direction, pulling it in the opposite direction wears it prematurely. It can also make a terrible squeak.
Andy Prokopyk ahh I see. Ty
Trodoil akaTroy
Ah… but the main reason to draw a file back is that doing so clears the teeth of what it has just filed off. It is the same reason why you draw a saw back… to clear the teeth!
The teeth point forwards, if you pull backwards you blunt the tool much faster, same goes for rasps etc
!? Which ones?
chloroform is the best glue for acrylic
don't be hard on the student!
