The longest moldings I have recently stuck (sticked? planed? profiled?) have been 16" ogees and ovolos at these various shows. I just haven't done much that has demanded a longer board until recently.
What's a sticking board and what are the advantages? Take a look at me last night and tell me if you notice a problem.
You can see the piece moving while I'm working. It's obvious if you look at the end near the camera. It bows throughout. Like everything else you can work around it (just like I do every day on Big Pink) but sometimes the planes will clog because it skips across the surface. Sometimes you do a belly flop on the bench as the molding comes unleashed and crashes against the back wall.
There are several methods for holding work steady. I like a sticking board.
I was asked by a reader for a brief tutorial in what one is and how I make mine.
I make mine out of melamine.
I cut a few 2" strips and screw them together
Joint an edge and then screw it to a 5" wide board
I countersink a few screws into both ends because there are times that I work briefly in the other direction.
You now have a sturdy backboard that can be clamped to a surface in only a few areas without having to worry about piece flexing in between. Tomorrow I will add a much lower backboard to the other side that I will use when working thinner pieces or when I want to tip the plane and the fence gets in the way. The fence not being used will hang over the edge of my bench.
That's it. The beauty of this option is you won't care if something gets spilled on it.
Next week I will give a lesson on a crosscut sled made out of mis-chopped mortises
Finally, I've been working on an interactive invention that allows you to gauge the the sharpness/dullness of any edge in any steel. Tell me what you think.
