I have been pondering the subject of home built toolpost grinders lately, so I did the usual Youtube research and discovered that there are quite a few that have made toolpost grinding setups and these range from being very well executed Toolpost Grinder Part 4/4 - YouTube (https://youtu.be/znTTiDv02GM) to useless deathtraps Homemade surface grinder set up for Lathe Machine - YouTube (https://youtu.be/ExOk3vxIqEM)
My curiosity revolves around why nobody seems to be building larger toolpost grinders with the build quality of Stefan Gotteswinter's as shown in the first youtube link. It seems to me that it shouldn't be that difficult to build a machine with an induction motor somewhere from 1/4 to 3/4 Hp that would utilise either a 4-8" wheel or a smaller stone for internal work.
I would imagine that bearings with the appropriate tolerance shouldn't be an issue and the machining seems pretty basic for anyone with a lathe and a mill.
What am I missing?
