Need help with math

a 360 turn of the hand wheel on my rotary table is 2.25 degrees of rotation of the table.
how much of a turn of the hand wheel = 1 degree of table rotation

[DR-Motion]

360 degrees rotation for handwheel = 2.25 degrees rotation for table

360 degrees / 2.25 = 160 degees

So 160 degrees rotation for handwheel = 1 degree rotation for table

160 at the handwheel. Odd number though. Most rotary tables are 90:1.

160 at the handwheel. Odd number though. Most rotary tables are 90:1.

The other common ratio is 40:1.

160 at the handwheel. Odd number though. Most rotary tables are 90:1.

Sherline's 4 inch tables are 72:1. Probably the most popular table ever.

Yes, that 160 turn table would definitely not be classed as a user friendly rotary table for manual use!

Hu, everyone knows true "user friendly" dividing devices have motors attached to them. Motors help prevent so much of our blood from draining out thru our knuckles
