This above is the workshop pencil that I am trying to describe below, on how the Celtic knots was produced.
This is the jig I made to produce the 45° Celtic knots in the pencil. You have to make 4 separate cuts on a blank that is exactly square and the same dimensions on all 4 sides.
Number the sides 1,2,3,4.
Whatever infill you use needs to be the same thickness as the kerf of your bandsaw blade you are using.
This is the pencil blank finished before cutting into separate turning blanks. Then drilling and turning and finishing with sanding to 1200grit cleaning with methelated spirit. 4 Coats of thin Zap CA followed by4 Coats of medium Zap CA then through the 9 micromesh pads, finishing with quality cr polish.
There a couple of good videos on YouTube show how to do this. However they dont explain the importance of square, sized blank and infill size to kerf cut.
These above are a bit more complicated but the same principle. Very time consuming to get the accuracy of the knots so they all cross inline correctly.
Hope you find this information informative you can see and not to boring
