Sambrook Posted October 14, 2015 Share Posted October 14, 2015 I am edging towards my first scratch build, and would appreciate some advice. I am planning a 3 piece laminate bolt-on neck of cherry. I've noticed a lot of laminate necks have the centre 'stripe' aligned horizontally instead of vertically like it's neighbours. Is this for structural reasons, or just cosmetic?

Roland Rock Posted October 14, 2015 Share Posted October 14, 2015 I'm having difficulty envisioning what you mean by horizontal and vertical stripes - can you post some example pics please? Quote Link to comment Share on other sites More sharing options...
Norris Posted October 15, 2015 Share Posted October 15, 2015 (edited) Do you mean that the wood grain of the laminates is aligned differently? It is probably to help stiffen the neck and to reduce warping. It is quite common to reverse the grain of the laminate sections Edit: if for instance you plan to laminate three strips of cherry you might want to rotate the middle section. I am planning a laminated through neck on my next build, so I would also welcome further comments from builders that have already done it Edited October 15, 2015 by Norris Quote Link to comment Share on other sites More sharing options...
Sambrook Posted October 15, 2015 Author Share Posted October 15, 2015 Thanks Norris, that is what I meant. So it does have a structural purpose... Quote Link to comment Share on other sites More sharing options...
Norris Posted October 15, 2015 Share Posted October 15, 2015 Yes. I think the idea is to counteract any tendency for the wood to bow. By reversing alternate laminations it balances out. However I'm not sure how you would arrange them if using more than one type of wood e.g. maple & walnut. Would you just reverse every other maple strip?

Manton Customs Posted October 15, 2015 Share Posted October 15, 2015 You want balance in a laminated neck so something like this[b] /l\ [/b]if a three piece,[b] \l/[/b] would also be fine. This is a rough illustration of the end grain when viewed from the heel of the neck blank or headstock end. This principle is basically the same for 5 piece necks too as the thinner laminates shouldn't cause any problems. The idea is to get as close to 1/4 sawn as possible (which would be vertical grain direction: [b]l[/b]) and to counteract movement within the pieces. So you want your central lam to be a close to vertical as possible and the outer ones mirrored. Quote Link to comment Share on other sites More sharing options...
