• Are you looking for a coupon code to buy my software? You can get one from lots of 3rd party sites but they won't work. My software never goes on sale and has never been discounted. The only coupon codes that are given is when I give a club presentation and I offer a discount to the attendees. Other than that, everyone pays the same price.

SEL formula

Exactly. Have you noticed there is no cross slide, compound, or leadscrew on a wood lathe? There's just no need for that level of precision. Even if you turned a piece to that level, it's going to change and move next spring anyway.

I don't know what a cross slide, compound, or leadscrew is, I'm just curious about the trig and geometry of a wedge as it relates to the ring. I am not seeking any precision, I am just trying to understand the SP calculations for SEL and board length, not to question the software or use more precision in my creating rings.

Looking through the thread I would hope you found the answer to your question regarding SEL and board length.
