Here is a video of how I remove a fretboard. I also talk about some other things. EB

Some guys used to use domestic household irons at work to reactivate adhesive but I always preferred a hot air gun. A neck / fretboard seems like a good use for an iron Eddie.

I'm gonna comment over on YT it helps the algorithm.
Yeah I got one of those upper class heating blankets but it's only bid enough for a bridge.

Warning- massive swerve ahead! Titebond has worked really well for me on my few guitar modifications.
Useless factoid: when I started out at my last place of work in April 1985, I said to my foreman "I'll stick it on with glue." (we used 3M™ "Scotchweld™" (Part# 9214 I think it was?) back in those days before we went over to "Araldite™" (part# 2013) and he snapped back at me "STEVE! in this establishment we BOND with ADHESIVE."
Ouch!
Far and away the best adhesive I ever used was the two part XB5308/XB5309 which I used as a trial to bond up an Egypt Air B737 galley one. I can't remember who made it but it was bright orange. I went to Heathrow Airport on a "jolly" to carry out some repairs and I couldn't break the bond with that adhesive. I clamped the job to some of that 3/16" thick steel curvy "W" shaped freeway barrier using "Carver™" spatter protected welders' cramps (phenomenal cramps- google!) and went at it with a club hammer and cold chisel. I have never encountered another adhesive like it. The company didn't carry on using it!
Scotchweld was a brilliant adhesive because it was tremendously strong but retained enough flexibility to work with a "monument" installed in a moving airframe. It was only because we had to mix it by hand in a cup from a footswitch operated two nozzle dispenser and wasn't available in cartridges that we went over to using Araldite. That said, I maintain that The Company had in mind its C.A.A. obligation to control the mix accurately (94:100) The latter could be supplied in cartridges with integrated disposable mixing nozzles and significantly- air powered delivery guns!
We used to carry out weekly checks on adhesive bonding efficacy. The guillotine operator would cut 1" wide strips of 16 SWG aluminium and they would be overlapped lengthways by about an inch. Adhesive would be spread on both surfaces and "scrim cloth" sandwiched between and then the joint was clamped under pressure. Once cured, a pull test on a Hounsfield Tensometer was carried out and the breaking strain recorded at failure, at which point it immediately became apparent when an operator failed to follow instructions by the failure reading and of course the absence of adhesive or scrim cloth. The environmental temperature had to be maintained 24 hours a day otherwise the readings varied. Occasionally, the aluminium would stretch and break before the adhesive broke. I can't remember the breaking strain but it was well north of a ton!
Regarding temperature control, I did a job on a B737 for Nicky Lauda's airline at Salzburg. There was five inches of snow on the apron and we couldn't get the tail fin into the hangar. The adhesive wouldn't set, so the engineers ran up the A.P.U. to heat the cabin. It got so warm that there were bubbles everywhere under the Tedlar™ trim decor, but happily they all went down when the heat reduced. It was so flippin' cold that I broke the end off my 16" long Snap-On #2 Philips!
I apologise Eddie for my reminiscent witterings.

WOW Steve, that is a lot of info on adhesives.
The only thing I ever did with metals was weld metal or sweat metals together using lead. But I worked on cars. Cutting panels off and making new ones and putting them back on. But I do seem to remember a product that came out right before I got out of car building that was an adhesive for putting car panels together. I never did get to use that stuff.
But I did use a lot of lead.

When I use the household iron I also use a little Tenma infrared thermometer to check the temperature. You can get them on Amazon and other places online. I also use the thermometer to check and recheck wax temperatures during pickup potting. John |

John, when you say little Tenma thermo are talking pocket size? I need to replace the meat thermo I was using so the little pocket one looks really affordable.
