Post subject:  Solid linings
I have been reading the archives and going down rabbit trails and noticed that quite a few people use solid linings. Can someone explain a little more about the technique of making them (ie dimensions layers ect) I am going to be doing mostly ukuleles but plan to slip in a guitar or two as I get better.

Thanks

Mine aren't anything really special. I just decide on the depth and width for the style I want for a particular guitar and make them out of 3 pieces that I hand bend over the iron and laminate together using the guitar as the glueing form. That way they fit perfectly. I fold a piece of baking paper over the side, so I don't glue the lining to the side during the laminating step. Use cloths pins and steel spring clamps just as you would to glue the linings in permanently. Once dry, I pop them out and run them past a rounding over bit in my router table. A little bit of hand sanding to tidy things up, and they're ready to glue in.

They are time consuming to make, but most definitely stiffen the side up compared to kerfed linings. You can use different woods for a striped effect, if that takes your fancy. I started to make them because of the cost of getting kerfed linings in Australia. The laminated ones cost me virtually nothing but time, and the added benefit of stiffer rims was a bonus.

I have over he years gone from normal kerfed lining, through reverse-kerf lining and a few years ago switched to solid laminated linings which I fabricate in a male/female mould using four 1.25mm (.050") laminates. They are just cold glued together in the mould and come out fully formed, I just round over the non gluing edge. I have noted that the switch from reverse to laminated was a degree of stiffness again as going from ordinary to reverse. Once the linings are on there is no need to build in the mould any more as the rims are completely set and stable as can be. Here's a couple of examples.

On the uke I built, I trimmed the sides to shape after I bent them. I had enough uke shaped leftover that I cut to liner size and used them as the liners.

This was my only build so taket that for what it is worth.

I bend two pieces of material about .100" thick and then glue like Collin in an inside/outside form. I usually make them wide enough to rip into two pieces. I rout an angle on the edge with 15 degree "bowl edge bit".

Colin, if weight is an issue for you, I found that all that glue really adds up. I used to cold form mine too and when I switched from 4 plies to 2, they were noticeably lighter.

Kent I worried about that, but before and after weighing of the laminates and the linings showed I only had much less than a gram of fish glue on the whole four together, that's less 1/28th of an ounce, not really something to consider. Plus I like the ease of not having to do any pre-bending, just put on the glue stack up and put in the mould.

In fact I have a job to see the glue line once out of the mould.

I could of course make them lighter by sawing little slots along them ;) .

Not beech, willow.

Colin, could we see pictures of the moulds you use?
