Advice on gluing kerfed linings

After a long autumn hiatus I am finally able to get back to my kit guitar. This evening I glued the kerfed linings onto the "back" side of the rim. I am using standard (not reversed) linings on a Martin OM kit with a mold.

I have a few observations and a couple questions regarding squeeze-out.

The first length of lining that I glued up I applied a generous bead of Titebond, spread the glue evenly with finger of choice (in this case--right index), then clamped the lining in place with clothespins. I had a fair amount of squeeze out. . .took me some time to clean it up but I think overall it went well. Squeeze-out amount lessened on the second, third, and fourth linings.

I cracked the lining trying to bend it around the waist, so I then followed instructions a bit better and sprayed the lining to moisten it, allowed it to sit for a few minutes, then clamped it to dry on the rim.

I noticed that I was able to get a better joint between the lining and rim when gluing if I clamped the mouth of the clothespin all the way to the thin part of the lining, towards the center of the rim. The clothespins would end up leaning towards the center of the guitar instead of staning up parallel to the rim. Make sense? Especially when working around the waist.

1) I seem to recall someone had posted a way to minimize squeeze out when gluing kerfed linings--maybe Ken Cierp? I was looking for this info by searching but I did not have any luck.

2) It seems to me that you really only need to clean up squeeze out on the thin side of the lining towards the center of the rim. . .the squeeze out that occurs between the edge of the rim and thick end of the lining will be removed when routing the binding channel. Correct?

Thanks for any advice.

Chuck, I'm not sure about the posting you reference in #1. But you should be careful about not cleaning up for #2. If there is glue in the path of the router guide bearings, it will cause problems with the channel being routed by leaving lumps. In my opinion, it's probably more important to clean this smooth. The glue inside is ugly, buy has no impact on the playing of the guitar and is less noticable than a gap on the front of the guitar caused by a lump in the binding channel. In honesty, you should take the extra time to clean both.

For this operation for the sake of neatness, its best to apply the glue with a brush. Use two thin layers one on kerfing and one on the inside of the rim gaging where the kerfing will line up and staying just shy of that line --- the squeeze out will be minimal and can be wiped off with a damp rag.

I am not following Lances's comment? But the glue that is left on the top edge of the kerfing is sanded off when the rim is contoured to accept the top and back plates.

Rubber bands #32 should/can also be wrapped around the clothes pins, this really improves the tension and clamping force.

Ken, my take on #2 is that Chuck is not concerned about the glue at the top edge of the rim. As you say if it's on top of the kerf it will get cleared when you contour the kerf, but my experience is that it does not tend to build there, but drip down the outside of the rim. So my comment was based on there being glue on the outside of the rim. Does this help clarify where I was going with my comments?

Thanks to both of your for your advice. I meant to suggest that the squeeze-out at the edge of the rim would be removed when contouring the rim, not routing for binding. I did not have enough squeeze-out to run down the outside of the rim, but I can see how that could easily happen.

I think the brush idea is a good one. I may try it when I apply lining to the "top" side of the rim.

I just apply glue to the kerfing by squeezing a thin bead of about 1/8 or less and then smoothing with a finger. I've never had any running or squeeze out that needs wiping....but you really just want a thin layer of glue on the kerfing.

As far as clamping: I've never liked or used clothes pins. They just don't get enough clamp pressure without some modifications. I have about 200 really small
small steel spring clamps that do the trick. I started out with 25 or 50 for the first guitar and liked them so much I ordered more as I continued building.
