Hey gang! would you lot mind giving me your opinion on this?
My next build is going to be a 17" archtop hollow body electric, and i intend to laminate the sides in three pieces, the middle of which will have the grain 90o to the others, total thickness 3.5 mm and do away with side bracing. I thought HHG would be appropriate for the lamination or maybe Titebond! epoxy would be overkill wouldn't it? Apreciate any comments, Cheere Rod.

Rod - I use Titebond to laminate my sides and it works fine.

I know a lot of the American builders use epoxy but I reckon it's overkill too. Glueing a joint as wide as a set of sides you could just as well use flour and water and it'd still hold. (well maybe not but you know what I mean) img~

Plus I like to use as little epoxy as I possibly can due to the sensitising nature of it.

I don't reckon you'd have enough open time with HHG to get everything in place and clamp it. Fish glue would probably work though.

Bob, do you use vacuum clamping to do the laminated sides or old fashion clamping?

At the moment I clamp it but I do have the bits and pieces to vacuum clamp. Just haven't got around to putting it all together.

Liam, if you are interested in vacuum clamping, check out Joe Woodworker's veneering site.

http://www.joewoodworker.com/veneering/welcome.htm

There is a ton of information there. Several of the others have built presses. Kim is the first one to come to mind, its early and I'm running off of less than 4 hours. So if I've misremembered, I'm sure someone will chime in and set you straight.

This is the final re-constructed message of this topic posted by the ANZLF help team.

Hey Rod,

I have never done laminations in a guitar sense, but have done laminating for chair legs, seats and done a fair bit of veneering with vac bags.

If you have a vac bag then use it (do dry runs to make sure eveything pulls down) or make a male and female former and clamp it like theres no tomorrow.

I agree that epoxy is overkill and also makes a huge glue line, Im always a bit weary with titebond and other PVA glues (just from the fact that it can let the wood move and cause creep and show gaps and visable glueline, which is bad when doing veneering in furniture.) I have used and gotten very good results with urea formaldehyde glue. very thin and waterbased for easy clean. It sets rock hard and there is zero glue line. i made some laminated chair legs and people thought it was steambent. It is brittle that could be the only issue against it.

hope that helped or gave you something else to ponder over, I havent really come across any people using it in lutherie tho.
