| yep my mill isn't full size (about 2:3) size but still can do a descent amount of stuff on it- I did a lot of work for my bots team= which equals lots of long nights in the basement, any way back to your disk, did you offset center, and then use a rotary table to rotate and cut at a slow speed | |

| for the disc, first i made a design in my design program and played with the on hole size and location until i got the center of gravity in line with the spinning axis. after i did that i cut off a 3/8 wide piece from my 4.5" cro-moly round stock. i then popped that in a lathe and faced both sides down until it was 5/16" wide, plus i now have a finished surface to work with, then i pilot drilled then plowed a 1" bit through the center giving me my arbor hole. now for the funer parts, i made a fixture that fit inside the arbor hole of the disc and held it on center of the rotary table. i then cut exactly one half of the disc to a 3.25 dia. then i drilled my bolt circle and balancing hole. i then cut off the excess material on each side of the tooth with a band saw. i then cut up to each side of the tooth using the radius of the end mill to cut the radius on the tooth. here is the on paper design, i takes a second to figure it out but everything you need to make it is there | |

| Man, you are a genius--I would ONLY consider doing this with CNC, but you did it with much simpler tools. Great work! | |

| thanks, it was fairly simple to. at least compared to the three tooth one, i only had to re-set it once and it popped right back into place thanks to the fixture. the one i made from ti was a pain, i spent like 20 mins resetting it to cut each tooth. | |

| Could it have been possible without the rotary table? Not that it matters, but I was just thinking that before we got the CNC, I had thought a rotary table would be a real help with the manual mill. I guess there's no reason to buy one now. . . | |

| not really sure how you would cut the radius without it, im sure you could change the design to straight cuts and have half a octagon on one side of the disc | |

| the frame is now pretty much finished up. here is a comparison shot next to the old version the current weight with weapon, drives, and battery is at 33oz witch is pretty sweet considering the weapon is 13oz of that | |
