This year so far.

I promised myself I’d keep posting at least once a month if not once a week this year… Apparently not happening.

Back in June I finally got a log of white oak (chinkapin oak specifically) for the roof shingle making project. The Ft Mifflin forge’s roof is in bad shape.

And I also acquired a red oak log at the same time.

So I started a pair of JA chairs.

And on Saturday I’m taking an online class taught by Elia Bizzari and Curtis Buchanan. The class is the first in a series for making Curtis’s “Democratic Chair”. Stay tuned for comments on the class…

Due to the covid pandemic, I had cancelled all classes and craft shows/fairs that I was going to do. And the wildlife refuge has shut the visitor’s center.

So I am actually left with too much time and dithering over what to do next.

But first I should finish the JA Chairs

Be well, stay safe

Making Tools: Straight Edge

I fear that I may open up a kettle of worms with this one. In order to produce a truly perfectly precisely accurate straight edge most machinist manuals will tell you to make 3 straight edges, and there is a process to “prove” them against each other…

I’m not working in metal, I do not need to be accurate to 1/10,000″ over the span of 4 feet.

I need it to be OK over the length of the straight edge.

So I probably should have made this post before making the post about the winding sticks. Because making a straight edge is like making one winding stick. (But one winding stick by itself is useless 😉

I have been using the same straightedges for decades, one @ 2′ long made from a fall off of birds eye maple and one made from plane maple but @ 4′ long.

After planing to thickness use your longest plane to make the edges as straight as you can. Use the trick of sighting down along the edge to “see” if it is straight.

Occasionally the edge gets dinged and I just re-plane it.

Putting a hang hole in one or both ends is a good idea too.

And you could make it a “notchy stick” by making cyma and cyma reversa cuts in the end. (a reference to Christopher Schwarz’ notchy stick)
