Drawing of driver's seat bottom

[JimC2]

I took measurements of mine today, drew it in AutoCad, made a PDF, and printed it full scale.
Tomorrow I will quantify the discrepencies and will correct them Monday.
Once I'm happy with it, would anyone like a full scale copy?

I measured the discrepencies; for the most part errors in hole locations on the order of 1/32" to 1/16". Several holes that look like they are centered on offset lines 5.25" either side of the midline actually vary a bit from straightt. Didn't have time to correct them in the drawing prior to Thanksgiving break. Will do so Monday or Tuesday.

Here's a pdf that can be printed full scale on a 20"×24" sheet of paper and traced.
With considerable pushing, twisting, finagling, and some moderately effective cursing, I was able to successfully mount the wood seat on a NOS frame.
