O.T. Using all thread in a cutting board project
I am making my mom a rather large cutting board as she needs it. between 2ftx2ft and 3ftx3ft. (Need to measure her counter.
It will be made of hard maple. She wants it flat (no feet) so she can use both sides. I was wondering if I could use 3/8 stainless all thread through it to decrease the likelihood of warping. Or will this just cause more problems? If I use all thread, should I use a tap and thread the holes the all thread goes through? Should I drill and install the all thread once it is glued? Should I use glue on the all thread? I will have to make this in "sections" then install the sections together. (My planer is not big enough to plane the entire piece. Any advice from you experts is appreciated! |

Disclaimer: Not an expert. Opinion based on many decades of woodworking: If you're talking about solid maple, it will warp. You can use plywood, as Jim referred to, or you can rip it into narrow (maybe 1") strips, *reversing* the side on each one, and edge-gluing them with something good (recorcinol is my choice but it will leave dark-brown glue lines; epoxy will do as well without the color).

I have examples of French saute pans that keep compressing their maple handles for just this reason. BTW, with epoxy, you won't need any more clamping force than it takes to hold the strips together.

That would probably be the more appropriate tool for thin strips. Or (to get maybe a little closer to metalworking), you could use a water jet or laser to do the ripping and then forego the planing altogether. |

(Typical butcher block styled edge grain)/ Then it sounds like you've done what you can to prevent warping. Really, if a thick piece of wood wants to warp, it isn't going to let a little thing like steel rods get in the way. The forces involved can be impressive. Again, the key is balancing the forces: don't let one side get wet without getting the other side wet. And don't let either side stand with water on it for long. My pastry board is 22" x 16", made of 3"-wide x 3/4"-thick edge-glued maple (I think; it's some European hardwood, and it isn't beech). It has narrow (2") boards tongue-and-grooved into the two ends, like an old-fashioned drafting board. After 35 years, it has not warped at all. When I wash it, I make sure to wash both sides equally (and quickly), even though the back side was completely clean to begin with. -- Ed Huntress On Monday, December 7, 2015 at 7:30:36 AM UTC-6, stryped wrote: I am making my mom a rather large cutting board as she needs it. between 2ftx2ft and 3ftx3ft.

Having made more than a few cutting boards , I say look at the grain on the end of your 1" wide strips . Make sure the curved grain lines alternate , whether up/down or side/side . My go-to glue for cutting boards is Titebond III - waterproof , holds great and it's approved for indirect food contact . If you're worried about strip separation , dado joint a cross strip on both ends - this will also help prevent warpage . After it's all glued up , planed , and sanded (220 minimum) treat it with olive oil - 2 coats minimum - soak it until there's standing oil then let it sit for an hour , wipe off excess, let it sit overnight and repeat . -- Snag |

Make it out of strips of wood with the grain at alternating angles. I would
think you would use bisquits and glue to assemble. Clamp tight to set and sand flat when dry. Ask on the wood working group to make sure. Those guys really know wood. I see you already did. Nevermind. |

(Typical butcher block styled edge grain)/ Then it sounds like you've done what you can to prevent warping. Really, if a thick piece of wood wants to warp, it isn't going to let a little thing like steel rods get in the way. The forces involved can be impressive. Again, the key is balancing the forces: don't let one side get wet without getting the other side wet. And don't let either side stand with water on it for long. My pastry board is 22" x 16", made of 3"-wide x 3/4"-thick edge-glued maple (I think; it's some European hardwood, and it isn't beech). It has narrow (2") boards tongue-and-grooved into the two ends, like an old-fashioned drafting board. After 35 years, it has not warped at all. When I wash it, I make sure to wash both sides equally (and quickly), even though the back side was completely clean to begin with. -- Ed Huntress One other thing about handling. Eventually the board will cup, no piece of wood is entirely stable. After washing both sides and wiping them dry, determine the direction of the cupping and put it on the counter with the crown up to dry. That way the long side (crown) dries first and shrinks faster than the short side (cup). Paul K. Dickman |
