<p>The bridge plate is partially separated, main cause of issues with top and bridge. I play on replacing with a slightly larger, slightly thicker rock maple bride plate. Surface prep prep for med CA will be the main issue. I hope I can get the bulge out by clamping before I try to glue with the 'quick' drying time of the CA. Other posts deter me from any 'heat' to get it flat 1st.</p>

<p>I have re-glued four or five bridges on Martins with the HPL tops. I contacted Martin to ask what type of adhesive should be used, they did tell me to use a medium viscosity CA. All of them have held up very well and none of them have let go yet. As far as the "bellying" of the top, I'm assuming it is like some of the others I have worked on, where there is a HUGE I guess you would call a bridge plate on the interior, but much less bracing then normal..

I have never tried to repair that problem on one of these, but I would think about doing some sort of overlay to the existing bridge plate. Maybe maple, or rosewood? With a little larger footprint than usual. My thoughts are once you get the bridge off, if you do an overlay and clamp it flat, that might help to flatten the top out some what........</p> Frank, any suggested plan B m…tag:fretsnet.ning.com,2012-05-14:2177249:Comment:880992012-05-14T14:49:19.636ZJerry Ryanhttp://fretsnet.ning.com/profile/JerryRyan

<p>Ok.</p>
<p> When I was in the business it wasn't like that here. The HPL that was used on rolled edge counter tops was very thin. Contact cement was the order of the day. I tried to lay a counter top by hand once using some of the HPL meant for rolled edges. It was VERY flimsy.</p>

<p>Ned, the laminate used on postformed countertops is not vertical grade laminate, it is regular full thickness countertop laminate.</p>
<p> With the application of heat, the edge gets rolled in 2 meter 3 meter or 4 meter lengths, to a 20mm radius (for a 40mm thick countertop, or 15mm for a 30mm top which is uncommon these days), and is then glued (with normal white PVA glue ), to the particle board substrate which has a corresponding radius machined on the edge..</p>

<p>I am of course talking about European style tops here ...when I worked in cabinet shops in the States, I was introduced to the rolled backsplash, which quite frankly, nobody in Europe would entertain, because it means that you can only mitre the countertop with a 45 degree miter which is unsightly in the extreme. With a flat postformed countertop, you can use a mason's mitre which looks far more elegant.</p>

<p>It's true that they apply heat to the plastic when they roll the edges and back splashes on countertops. It should also be pointed out that the laminate used for this process is approximately half the thickness of the regular countertop laminate. I don't know how this stacks up to the HPL used by Martin in their guitars but I think that Martin is using a heavier HPL in their construction. </p>

<p>Heat can be applied to almost anything and it will help it bend but is it called for in this instance? My personal opinion is that it is not needed. The heat that is used on a rolled counter top is used to help make the top material a bit more plastic to relieve the stresses caused because of the degree of deformation needed. In the case of a bulging top, you just don't need to move the material all that much so rather than helping, the heat could do more damage to the glue joints between the top material and the braces. </p> HPL although obviously imperv…tag:fretsnet.ning.com,2012-05-12:2177249:Comment:878742012-05-12T18:14:28.274ZMurray MacLeodhttp://fretsnet.ning.com/profile/MurrayMacLeod
<p>HPL although obviously impervious to moisture, certainly <strong>does</strong> react to heat, and can be made malleable by the application of heat.</p>
<p>How do you think they roll postformed edges onto HPL countertop laminates ?</p>

<p>Just heard a good recommendation for a specific medium viscosity CA that Martin uses to paste the bridge back on - SCOTCHWELD PR600 from 3M. It's a slightly flexible version that supposedly resists cracking off as easily as the regular stuff. Depending on cosmetics, I'd reuse those bolts or replace them. And, for structural stability y, I'd consider a solid reinforcement below, too.</p>
