I wanted to further develop my mitering technique, so I purchased 4 top-tubes and went to work. This resulted in 100 mitered joints. The good thing about doing these as a practice exercise is that I could try different things to learn worked best for me, even intentionally mess-up a miter and then see what was needed to correct it. I learned quite a bit in doing this, and developed a repeatable process that produces consistent results. My future frames should be better for it.

Thanks for looking.
