I was given an excel spreadsheet that also figures out bevel angles from a fine member here on the forum. Now i want to make my own. I have a friend stopping by for brats and beer on monday who is a retired computer programmer. And he said that when he worked for Hp he fixed excel and its issuesmany years ago. So i think im in good hands.

But today he asked me if i had the formula for the bevel angle to input. I had to tell him no but id try to.get it. So... anyone have this info? What would be needed to input into excel? He said he ould most likely come up with it but if i could find it would be quicker.

Thanks for any help.
