The cross cut sled is assembled, but not precisely adjusted, yet. This calls for patience and precise work, as I’ve learned from painful experience. In total, I needed six attempts until I was satisfied with the results. However, I am now!
Via Michael Truppe’s video channel “Let’s Bastel” I learned about the fice-cut-test. This was apparently invented by William Ng, who demonstrates and elaborates on the underlying principles it in a youtube video. Truppe summarizes it in german.
The easy part was constructing the sled bottom. Now it’s getting straight at the nitty-gritties, namely construction the fences and attaching them.
The front fence needs to be as level as possible, so it can’t just be cut from a single piece of board. Almost any board has some kind of warp which is simply inacceptable for a precise fence. Thus, the front fence has to be comprised of a cornered construction that is self-centering.
As I mentioned in the construction report, I made a mistake while building the vertical stabilizer for my biplane, namely not chafing the trailing edge. Attempting to correct this using the transverse stop thoroughly failed. In order not to have to repeat this experience, I’m building a cross cut sled for the circular table saw.
However, a cross cut sled is capable of many more things. For once it facilitates to repeatively cut slats to length, thus one can skimp on a mitre saw. And then one can use it to get small boards back to right angles which were cut crookedly, so they can be rip cut again. So today is about the first part of a mini project which will facilitate my other handicraft.
