| Bernd:
Only thing I can come up with is to use an angle grinder and grind the fins down to where you won't have much of an interupted cut. Might be a bit messy but should work. Bernd |
| John Hill:
If the fins are cast iron it might be easy to take them off with a cold chisel. |

I cut the fins off with a hack saw. After resharpening the tool bit, it cleaned up nicely. Pics tomorrow. Chuck in E. TN |

Time I got back to work on the rotary table. Here's the materials I have gathered to date. 4" x 4" x 3/8" crs plate 4" x 2" square tube 4" x 1" round steel 3 1/2" x 1 1/2" round steel bearing from treadmill roller worm from treadmill incline I turned a bolt to be a sliding fit to the bearing for an axle. Today I was looking over the parts wondering which worm set up to use. I placed the 80 tooth change gear from my lathe next to the worm screw and wohoo! It fit! Next, I tried the fit of the gear on the axil, WOHOO! Twice in a row, it fit! Is that beginners luck or what! Now to think about which gear to actually use in the RT. A 60 tooth gear would give me 6° resolution; an 80 tooth gear, 4.5°, right? I'll ask for recommendations on the choice of gears, as long as it is a mini lathe change gear... Now I feel confident this is doable for me! I am going to turn the 3 1/2" round to be a duplicate of my minilathe spindle nose so I can easily use my 4" independant jaw chuck, 3" 3 jaw chuck, or faceplate. So, today, I will work on the spindle nose and on cutting off a piece of the worm screw and making an axle for it.. I have a couple of skare bearings set aside for the worm screw axil, also. I have posted pictures here: http://s571.photobucket.com/albums/ss157/chucketn/Machining/Rotary%20Table/ By the way, how do you put pictures into posts? And, forgot to add, I gave up on using the tradmill flywheel when I got the big disk sawn in half. |
