Dear sweet Jesus I think i have some research to do. I think I just went in over my head.
Appreciate the sentiment, but I found my metric tape measure.
trust me I hate SAE.
I was thinking I could bend a parabola out of oak lumber I can get very cheaply. Assuming I do it carefully I can get a fairly predictable curve from a good hardwood board, then simply put in the screws. there's just the question of how to make a prescribed curve.....
