I'm stuck on how to work out how many turns of the handle on my vertex 4inch rotary table..
I understand that my gear ratio is 90:1 so 90 turns of the handdle will rotate the table through 360 degrees, one turn of the handle is 4 degrees
I want to cut 16 slots in the ali as shown in the picture below, so far i have cut 8 slots. I found my starting point and cut the first slot then rotated the handle 11.25 turns, to cut 4 slots its 90/4 = 22.5 turns so 8 is 11.25.
Now i want to cut another slot which would be every 5.625 turns of the handle..half of 11.25
How do i work that out using the minutes and seconds? can someone explain whats what on the scale please?
My understanding of it is 0-1-2-3-4 4 degrees split into 60 mins, 30 min mark in the middle of 1 degree
Thanks
