Glued 2 8’ walnut slabs for a table. Used dominos to level the slabs, not for strength. It is important to make sure the slab/domino combo fits and makes a tight joint before applying glue. Fortunately I had experienced guidance. The dominos worked well to make a level joint.
Thanks for posting. I have had a Domino 500 for a year or two and enjoy it a lot. I have found it to be much more useful than a plate/biscuit joiner. I like Titebond III also, but just found out they make a brown Titebond II that might be good for walnut, but have never had a problem that brown glue would have solved.
I'd like to see pictures of what you are doing. How big are your slabs? Making a table? What are you doing or a base?
I am still thinking about slab tables. Not sure about "Bark on" or "Bark off". I do know that's quite a feat to keep walnut bark on and in that good condition. Nice slabs.
How did you pull them together without damaging the bark?
Is this for you or are you selling it? I am struggling with making furniture and what price to charge. Recently someone asked me about making them a slab table. I Said "That would be a $5000 table" and they said, "That's right." I sent them to a local company that has a huge stash of slabs. Now I wonder how that worked out. I just find it hard to believe anyone will pay five grand for a table.
The table is for daughter and son-in-law. Bark came off. Bark was thick and would not have been attractive. It is also difficult to keep on. I have a small table of spalted maple in our home that I “glued” bark with shellac. I will reattach it with glue if it falls off. I would be hesitant to sell such a piece. Good luck getting a fair price for custom furniture.
Thin CA will stabilize bark. I've used it successfully on natural edged bowls. It makes it easier to manipulate the bark later, e.g. when removing loose surface flakes, cleaning up around knot holes, filling larger voids, judicious sanding, oiling, and finishing.
I sometime find bark attractive, but I can not imagine a dining table with walnut bark on it. Rough and somehow offensive to sit at and eat. Impossible to clean.
