A Pair of Bulge Boards.....

I built 2 more of these popular boards to help out my sister in a fund raiser today for her fight with cancer.

Since there are an odd number of squares, I built 2 board blanks so and ultimately 2 end grain cutting boards. There is a blog here showing the construction using the mortising machine and giving proper credit to Scott for the idea.

Besides being opposite’s in terms of light/dark, the boards differ slightly in the placement of the little square inlays in the corner. Note that the camera does seem to capture the illusion better than the eye.

The blog covers the build of the first board which is on the left of photos 1-3 and the little squares are spaced farther from the corners. Up close (with the human eye) this board is not as dramatic. But from a distance, it is more pronounced than the the one on the right, where the blocks are closer in the corner.

This was kind of a surprise.

Hard Maple and Walnut, Mineral oil finish.

These are fun to build and always draw the comments….....

Thanks for looking.

Beautiful work.

I guess the first board works better is because the second board causes one to notice the big X’s instead of the ‘random’ placed little boxes. (?) I always wondered if it would work with the little ones in the extreme corners – now I bet that it would not.

They are really nice.
Good luck,

Those are exceptional! But I got a headache just watching you do these. They look impossible to me but you made them flawlessly.

Thanks KDC, appreciate it…........

Steve, I’m not really sure exactly…..they seemingly change every time I look, plus my eyes ain’t what they used to be…..thanks for comments…

Rex…..I seem to be drawn to weird…...thanks for stopping by…

Andy – thanks but I can point out the flaws if you wish! I was happy that all the corners matched up, sometimes easier said than done. Appreciate the comments!

These are no boring boards!!!
Almost a shame to use & cover them with food.
The idea may have been originated by Scott….
However, you get full credit for the execution!!!
Well done, my friend!

These look amazing. I want to build one myself but I don’t have a mortising machine… hand chopping that many tiny mortises is beyond my skills, especially in end grain.
