Sloyd lathe work...
In B. B. Hoffman's book, The Sloyd System of Woodworking published in 1892, a chart is included explaining the advantages and disadvantages of various crafts for use in school. Of Sloyd lathe work, it says in response to the question,“Is it in accordance with the child’s capabilities? No."
Among further questions and answers are these:
Does it give a respect of rough bodily labor? Hardly.
Does it train to habits of order and exactness? Partly.
Is it beneficial from the hygienic point of view? No.
Does it allow of methodical arrangement? No.
Does it teach general dexterity of hand? No.
To all of these questions and several more, Sloyd Carpentry was given a resounding yes.
N. Christian Jacobsen had noted that if knives were to be considered too dangerous for schools where children would be under close supervision by adults but that children were to be allowed to use them unsupervised outside of school, there was a false logic at work. Would it not be better that children be taught to use knives safely and responsibly as tools of creativity and not danger?
In drilling through a cube, I had difficulties getting the holes drilled from opposite ends to align at the center and in seeking the cause, I found that the table of the drill press was tilted slightly. About two degrees from ninety meant that the holes would miss rather than connect. I made two iterations of jigs before I discovered the fault. Now that the table has been trued at 90 degrees, both jigs work better.
My second jig was formed using the table saw. First I cut the edge of stock at a 35 degree angle and then cut 30 degree miters on the ends to form the jig shown. The jig forms a perfect nest for the cube to fit as it is drilled.
It was challenging to figure out the bedding angle for the flat surfaces to support the cube in the jig. If I'd paid more attention in geometry class I might have been able to figure it out. Instead, I used trial and error. The first plane was cut at 45 degrees. When that didn't work, I adjusted the saw by 10 degrees to cut 35. That angle fit the cube like a glove. The results are shown in the photo below.
