Peter that cam grinder is a thing of beauty and lovely workmanship and design.
I think it should be called the Quorn of cam grinders.
Thank you for the offer of some drawings but I am far enough into making some parts that I am more or less committed to the design I have in my head.
The headstock is completed apart from engraving degrees for the indexable chuck. Once that is complete I can assemble the parts and press the bearings home and and fix the headstock to the bed. The tailstock will be next.
I will take photo's before and after assembly.
The design I have in mind is a master cam with the grinder attached to a swing frame and 4 to 1 size reduction. My aim is to keep the design as simple as possible within design constraints but with close tolerance fit of all moving and sliding parts. I have built a tool post grinder so have a bit of experience with some aspects of the design but I am a bit of a slow worker as my trade was storekeeper not a toolmaker or fitter and turner but have learned a lot from making the Edwards Radial.
Promise some photo's soon - Cheers all - Brian
