I am going to show you all a video I made on how to delaminate a bad glue up without destroying the project using a heat gun and also without having to make any cuts, this method will work on any joint and it doesn’t matter how long the joint has cured, the glue that I used in this video was Titebond II.
How I figured this out, I had a bad clamp on a warped project and wasn’t sure how I was going to fix it thus I was just going to leave it and make it work, I sat the project down, walked away from it and it was that very next morning that it came to me to use heat, I had remembered reading how to remove glue from bar clamps so I knew it had to work and sure enough it did allowing me to fix the problem, the photos below show the project I was working on at the time.
In these photos below I am showing you where I was able to fix a couple bad glue ups that went unnoticed when clamping once the glue had dried for a good 18 hour period I had removed the ratchet straps along with clamps to find that on the bottom of the box in each corner I had a warped face plate that stuck out 1/4” on one side and an 1/8” on the other side by using the heat gun and small bar clamps strategically placed up along where the face plate was not up against the inner core I heated the glue joints up and gradually and slowly cranked down on the clamps as the glue turned loose from the heat it closed the gaps and made the faceplate up tight against the inner core of the box where it was re-glued.
