Hi,

When it comes to kerfing, I notice there are starndard, bevel standard, and reverse...perhaps there are more but I see these three.

I'm curious to what kind of kerfing you use and why over the others?

Thanks, David

I use Reverse kerfed linings .....It seems to hold the shape of the rim better than standard kerfed linings...I have been thinking about using non kerfed linings ...Is there any advantage or disadvantage other than weight?

I just put reversed kerf mahogany linings in my first acoustic. They just seem stronger, like Todd sez. I couldn't bend them around some curves, though, even with the pipe, so I had to resort to installing them in small pieces. This seems to defeat their rigidity somewhat, so o more kerfings for me, on my next guitar I'm switching to laminating Spanish Cedar for linings....

David just so you know I was not getting on to you the calling kerfed linings kerfing has been an ongoing humor for a long time

Michael P,
No offense taken at all. [:Y:]

Todd S,
I forgot that you told me these were called lining. I just happen to see the web of few suppliers and that's what they were calling it and never thought twice.

I use kerfing to allow my linings to bend without heat bending them. :lol: That term has a lot of history and discussion around here.

I actually heat bend the kerfed linings anyway, but I use reverse spanish cedar. As said above, it holds its shape better and I like the look.

Laminated solid linings, glued up in a mould. No bending needed.

So I don't actually use 'kerfing'.

I like the glue-absorbing properties of reverse kerfed linings. Really just much cleaner to work with. I also find that they're easier to clamp because they have a flat surface that's parallel with the side.

I don't care either way what you call it, but something just occurred to me. Do those who are so adamant about not calling them kerfings go to an art museum to look at painted canvases or paintings?

Tony, I'm intrigued by your custom linings. I'm not building replica Weissenborns per se (I have changed a lot of aspects of the original design in my builds) and find off-the-shelf linings do the job perfectly for me, but I'd be quite interested in the process you go through.

I received some mahogany reversed kerf linings from Bob C at RC Tonewoods last night. I'm looking forward to using them. I went with reversed kerf because I'm trying to make the sides as stiff as I can. I plan to laminate .020" carbon fiber to them as well. The reverse kerf gives me a nice glue area for that.

I recently started working on installing linings for the first time. My first attempt was reverse linings. They look good but are very touchy to get then installed without problems. For yucks I put a .200 x .625 maple scrap in my bender and bent a solid lining. It turned out great and have started playing with other woods for solid linings. I like the look of solid linings and will probably stick with them.

I made these Charles Fox style two piece liners. Black Walnout for the kerfed part with Tasmanian sassafrass for the capping . Very solid !

I've never encountered any issues. What problems did you have exactly?

Colin, are your sides the same width all the way around? If not, how do you handle moving the lining down the sides in the upper bout while going around them?


Craig, it looks like you are using kerfed linings with a thin cap on them. Is an accurate description?

Post subject:  Re: Kerfing, what do you use?
Yes , that's basically it Lillian, except that the kerfed part isn't wedge shape. It also has a rebate to accept the capping for a flush fit.

Cheers , Craig Lawrence

I use a normal 15' back and 25' top. Pre-profile the back before bending, and install the linings as normal. Then sand in the dishes.

I wish wish wish I could buy my linings. But since I build reproductions of old Weissenborns, which feature funky shop made linings, I have to make them the same way also to get the look but also lighter weight because of the smaller body size than a regular acoustic.

Who is the man to call if you want funky custom made linings out of a specific material?



I use those same funky linings on my ladder braced guitars and have to make them myself, but I'll not be making yours since It's not my favorite thing either. I usually just suffer thru making as many as I can tolerate so I don;t have to do it too often.
