Shooting Board The Ramp Part 3
To even out the dulling of the plane blade, I like the idea of a ramped runway. The bonus of this is a skewed blade. What I dont like is the idea of either having to live with the ramp in all applications or having to make two Shooting Boards. Hence the Adjustable Ramp.
Here is the results of my efforts to come up with something that is workable in all configurations...
My grade 5 math teacher taught me that any angle divided into two can be made into a right angle by flipping one section, so I applied that theory to this ramp. First I defined the heights to have the bottom of the plane blade strike the stock just above its lower edge at the start of the runway, and did the same for it at the Shooting Boards fence. This gave me the angle. I then completed the piece by giving it a flat bottom. I then divided it into two equal pieces.
As the plane is going to run in tracks, it means that the top piece requires two sets of them; one set for the plane to run at the angle, and another for it to run when this piece is flipped to produce a flat runway. This meant I had to find the sweet measurement that would allow enough stock to let the tracks into both top and bottom surfaces, yet keep the Shooting Boards height to an absolute minimum. The result is an overall height of 4 1/2".
Im still searching for some hardware that will allow quick, but solid assembly and disassembly. There must be something out there.
So this is the basis of the project, which still needs some fine-tuning before any wood is cut. If anyone has any comments, observations or advice, Id love to hear it.
Peace,
Mitchell
