I need help with a problem I’ve encountered building a small kitchen Island/builders block.
A few months ago I began working on an project composed of two parts.
the first was to be an old school end-grain butchers block made of steamed beech
The second component was a kitchen island/cabinet containing 2 full width drawers that allowed the butchers block to rest at bench-top height when completed.
I began building the end-grain butchers block by sawing all the component pieces (64 pieces 95X45X150mm deep framed all round by 45mm thick by 150mm deep frame. At this point it was all looking good and I went so far as to drill 2 x through the 450mm width of the block to reinforce/ clamp the block together using 10mm rebar, nuts and washers.
All this was dry fitted, then glued (with standard PVA wood glue), & clamped in place and at the end I had a lovely looking butchers block.
The steamed beech had started to warp and move to such an extent that in several places I could see right through the 5mm (1/8 inch) gaps that had opened up in my lovely work. (i’d say 50 percent of the joints remain perfect and the remaining 50 are all shifting and warping).
I’m now at a point where I want to unglue the whole mess and start again, and I have 2 questions for you knowledgable and experienced lot that I’d appreciate some help with.
1.. How do I go about unsticking the whole mess?
I’ve tried heat from an iron.. it works very well, although only where I can get direct application of heat to the woodglue, and as such is impossible to get into the joints that I need to get unstuck.
I tried using one of my japanese handsaws to make very fine cuts along the joints, but the friction seems to melt the glue, clog the blade and render them ineffective.
I’ve tried injecting white vinegar via a syringe onto the joints, but this doesn’t seem to work. (Although I’d be willing to hear of anyone who has done this successfully)?
I’ve heard of people using steam, and this may be the next step.. but I would assume then all my pieces would need to be dried again for (I don’t know ) how long before I could attempt re-assembling the whole lot?
And lastly, and almost more importantly.. How do I prevent this from happening again?
Anyone with any ideas/experience on how to go about the process of unsticking this amount of glue and making it all work a 2nd time around would be gratefully revered in our household for years to come.
I hope this is clear and understandable, I’ll try and post some pictures of the problem tomorrow.
