Here's my variant:









This grinder, with its large table is going to be extended for lathe tool processing.
Some holes are to be added to the plate as well as a vise for gripping the shafts.
Note the table displacement : a rack made with an M14 bolt cut in the middle and a wheel machined with an M14 tap as a hobbing cutter.

Currently, I'm building a Quorn variant.
The Gadgetbuilder's design is not easy to adapt for grinding milling cutters and I was in a hurry to get my drill bits correctly ground.

Gadgetbuilder's design has been built by quite a few other folks, including one version that uses mostly 3D printed parts.? Lots of interesting variations, the main thing is to achieve the right geometry for the profile(s) you want.? IIRC, some folks have built adapters for it so they can sharpen end mills.? Probably just the bottom face, that's the easiest to sharpen.
