<p>Mate, that is a party trick akin to pulling the table cloth out from under the crystal.......I'm going out to buy a Block-splitter and some safety glasses. Excellent and enjoyable stuff David - a real eye opener and technical tour de force for my jaded and cynical mind.</p>

Tomahawk aside, cold chisel removal has it's place. This instrument for example, with the bridge essentially superglued to the finish, you can see how perfectly clean (literally not a single chip, scratch, or shred of wood) it came off. Heat could have softened the finish as much or more than the superglue that was sticking to it. Shock resistance is a weak link with standard CA glues, and this is a perfect way to take advantage of this.<br></br>

Shock resistance is a weak link with standard CA glues, and this is a perfect way to take advantage of this.<br/>
<br/>
Even on old hide glue joints there are times I may pull out the hammer and chisel before the heat lamp and spatula. If years of cyclical seasonal wood movement appear to have significantly strained and weakened the joint, or extreme environmental conditions essentially crystallized a glue joint that was left too thick, I find politely shocking the joint can sometimes be a more effective means to cleanly separate pieces.<br/>
<br/>
To be honest it's relatively rare that I use the cold chisel method anymore. Still, every once in a while I see a joint where the signs or my intuition tells me is ready to pop clean with a bit of shock. I wouldn't use it on PVA joints (too much elasticity to come clean with shock even after they start to fail), but with many newer import guitars and the occasional hide glue joint that appears ripe to pop, it's a method that still has it's place.<br/>
<br/>
The guitar in the video by the way, already has the bridge glued back on and you can't tell it was ever removed. I stuck it back on with supeglue of course, to keep true to original factory specs. ;) Next we may demonstrate how to set up your golf swing to cleanly drive it off. Then if we can find the bridge after that perhaps we can move toward demonstrating more aggressive methods for those really stubborn joints (though we may need to apply for federal permits to show those).

<p>Looking at that D-28 cold bridge removal makes me wonder how much stress is being conveyed to the rest of the top joints? I have popped off bridges on cheap guitars with nothing but a putty knife, but I would be worried about stressing a quality instrument.</p>

<p>I learned the cold chisel authoritative whack with a hammer method back in 1980. I was working for a wholesaler at the time and the guitars were rescued inventory. A year later I got hired by the local Fender rep to cut the label out of the back of 300 acoustic guitars. I used a panel bit, plunged through the back and followed the back braces. I was paid well for the job and was allowed to keep whatever parts I could salvage as I went along. Well, besides tuners, saddle's, nuts and some…</p>

I was paid well for the job and was allowed to keep whatever parts I could salvage as I went along. Well, besides tuners, saddle's, nuts and some pickup systems, I took the opportunity to remove most of the bridges using a chisel and a hammer. A rare chance to develop a technique that I still use occasionally. I'll watch the video now.</p>

Ah, had a suspishiom it was roofing/nail pulling related, that notch is pretty indicative. I couldnt bring myself to ditch an Estwing, so with me it stays.

I found this thing buried in the dirt a couple years ago while landscaping. Not sure what its really for, but Ive always kept it around just because. Looks like Ive found a use for it!
