<p>Thanks Taff - </p>
<p>What you're suggesting makes perfect sense.</p>
<p>The photos I posted originally were without a bridge as my bridge took a trip through my jointer (don't ask).</p>
<p>I've since created a new bridge (see attached) and put a thin smear of hot glue to the back side of the piezo and mounted it beneath the bridge under the lid - that made a world of difference.</p>

<p>Again, I'm puzzled as to how some cats are getting the 'glue in the bottle-cap' method to work. The only thing I can think of is to fill the cap with hot glue and then rest the pickup in the 'pool' of glue while making sure the back side is flush to the edges of the cap. This way, when placed against the box the disc makes contact. <br/><br/>If this is a feasible solution, I can't really see what purpose the cap would serve aside from aesthetic.<br/><br/>Anyway, I did get it sorted. Here's a quick test drive with my second build to show the sound... not bad considering it's a little 9V, 4" speaker.<br/><br/><a href="https://youtu.be/GCmZ1oqJA9M" target="_blank">https://youtu.be/GCmZ1oqJA9M</a><br/><br/>Cheers -<br/>Mike</p> Hi, my first thought re the p…tag:www.cigarboxnation.com,2017-10-20:2592684:Comment:29644712017-10-20T21:50:00.878ZTaffy Evanshttps://www.cigarboxnation.com/profile/TaffyEvans
Hi, my first thought re the problem is this. A piezo pickup needs to have vibrations or pressure for it to work. The reason it is placed on the soundboard is that is the greatest source of strong vibrations. This is due to the bridge location on the top being at the sweet spot to make the top plate vibrate.<br />
<br />
In your CBG it looks like the bridge is not on the sound producing part of the top but on the very edge, and under that is structural timber. So maybe limited vibrations equals limited…

<p>Man, I know...! - and old enough to know better. I grabbed some 'chopstick' like scraps to try to guide it through and it suck into the blade almost instantly. I'm seriously eyeing up that shaper/sander for the drill-press at StewMac. I think it would lend itself to better consistenct on these small parts.</p>
