First off, let me start by saying that in no way, shape, or form, is the idea for these jaws of my own doing. I got the instructions on line and I just took some pictures as I was going to pass the information on to you fine folks as I like to do.
The dilema started when I priced One Way's jumbo jaws for the lathe.
I was shocked at the price of them and decided to ask if anyone here had made their own
. I got a ton of great information from you guys and decided to make my own Cole jaws and post a build/tutorial thread. So, here we go.
I started of with a 10" X 10" square of 1/2" plywood and drawing a line from corner to corner, I marked the center.
I then removed the jaws from my chuck and laid them out on the plywood. I marked the position of the mounting holes and carefully drilled and countersunk for the plywood to accept the bolts. The hole in the top left corner was just me testing drill size for the bolts in the waste area.
The next step was to draw the circumference of my "Kenbo jaws"
Time to cut the circumference. I chose to use the scroll saw, but you can use the band saw, jig saw or whatever your little heart desires.
I then drew a line, 22.5 degrees on either side of each center line. These lines will provide equal spacing of our hold downs at a later step.
