We need a rotary grinding fixture that will be set up for one specific job. It will never do anything but this one job. Ever. It does not have to do anything exceptionally well, just "well". I've been doing the task with a hand cranked Harig Grind-All, but it takes up way too much vertical space, and the hand cranking gets old. QUICKLY. I know we can purchase a motor and pulleys from Harig to overcome that, but that does not solve the work space issue.
So, I thought purchase/murderfy something to suit. All it needs to do is to hold a part at approximately a 5° incline and spin at approximately 20 - 60 RPM. I am fine with accepting that some minor work will be necessary to insure good results. At first blush, it seemed too simple, and I quickly found two items that together would fill the purpose well when assembled together. My thought was to combine a small, tilting rotary table and an adjustable speed sewing machine motor. However, I admit that I am having a hard time swallowing the idea for personal reasons.
These are what I am considering bodging together and connecting with a timing belt. My thought is to pull the handle from the table, replace it with a timing pulley, mount the motor to the side of the table, install a timing pulley on it, and connect the two with a suitable belt. Lastly, a small block will be mounted to the edge of the bottom face of the tilting member, opposite the hinge point, to set the angle.
Tell me why this is a bad idea, or point me to a better idea in a similar price range.
