/diy/ - Do It Yourself

the way your describing is how we made them in school (pic related, at the end of every year i was in school i looted the scrap bin and took all the projects for next year they were throwing out, incase i fucked up mine) the actual whirlyjigs use crossed roller bearings for max accuracy and rigidity. i know i say crossed roller a lot but for linear low speed rotational, they are the top of the line
beside it is a pic of my high/low speed with harmonic gearbox and 4x angular contact bearings. i use angular contact bearings instead of crossed roller because my spindle is also highspeed.

the grinder i use has a vacuum but never fucking seems to work, i put my shirt over my nose, but its even while mchining on my mill, its just powder.
>lifting forces n shit
it was mostly for wear and speed purposes, but i also dont want to make/grind a lot of shit even more
