Tool Grinder (maybe)

[f350ca]

Felt like playing on the lathe and mill, they were feeling neglected.
This may never get finished in a reasonable time frame but should be a fun project. Another one of Greg's design as we machine builds.
Why a tool grinder?
This stems from wanting a wood processor, it would be easier to built with a cnc plasma table, rather than buy racks I want to try and build them, I need a dro on the shaper for that and a grinder to make the cutter angles exact and repeatable. This all falls into Greg logic, Like building a sawmill to cut the timber for a blacksmith shop.

I basically want a grinder that I can set two angles and use the face of a cup wheel. These are available but it would be cheaper to buy the rack, or almost the wood processor, remember the wood processor.

I needed a 90 degree joint with adjustment on the resulting angles. Had a chunk of 3 inch dia cast iron (no idea where it came from).
Made a threaded arbor to cut the 90 deg joint.



Not sure what to call these parts but this makes the 90 degree joint.





The assembly will pivot on a 1 1/4 shaft. Bore for that.



3/4 bore for split cotter to lock to shaft.



Degree lines for cutter clearance. These are 5 degrees apart with a vernier to get to 1 degree.



Thats where we are now, may get some more tonight, today we're filling the wood shed, too nice a day to be inside, 22 degree Celsius ( in November ? thank god for global warming)
