Thanks Mark,
You always find something complimentary to say, I appreciate that.
If you look at the picture with the acetone, you can see the bevel on the edge of the blocks to guide it down. (Bevel is about 3/4 of the block then flat on the end.)
Solid surface is just like wood. All the same tools and easy to do. Just harder, and makes a mess like mdf, except the particles fall to the ground quicker.
I had thought it would be more interesting, since nobody ever shows it.
Figuring out how to do something you have never done is what makes a good challenge.
