Hi Mudamaker,
Yes, I think there would be interest in plans or kits if you can find stock parts to use, like from Graingers. After 40 years of courses using six of the antique machines here at Heartwood, a number of engineers/machinists/students have tried to replicate them economically without success. They end up costing more than buying an antique one.
Worth trying with a fresh set of eyes, tho.
