ah, but old school was all we use to have.. Bridgeport type mill and a rotary table can make a ton of stuff Rotary table on a sine bar...now you have 5 axis...just not cnc. In the old days, my Dad had me run surface grinders that didn't even have hydraulics on the x axis...all 3 axis were manual...man, talk about a real workout. Drop the Z .0003 move the X back and forth while moving the Y 1/4 the width of the grinding wheel. I do NOT miss those days, ha ha. Bill |

A rotary table is on my 'list'. Right after a 15HP Rotary Phase Converter setup for my 20x60" lathe. Probably a 5HP across the line unit that will be used to start a 10HP motor. That should be sufficient to run the ~7.5HP (5.5KW) lathe motor. I have to do a quick reverse to cut metric threads since the lathe has an english leadscrew. I usually have to find used equipment to fit my budget...
I did get some sine bars with the mill along with a ton of other tooling. The former owner used it to make model RC aircraft.

This is a little late, but there have been other people asking about how I did this. Didn't have any type of cutter at the time, so I marked off a spare CVT cover I had of where I wanted the retainer to be cut from. I then used a drill to "peforate" the outline. With a standard hammer I pounded the case off while holding the piece I wanted to keep. Took the saved piece to work and with a few minutes on the grinder I was able to shape and smooth out the edges. Been running this way for over 2 years now. No broken belts since this mod. I love how easy it is to work on the transmission now.  |

3D printing with some glass filled nylon may make an acceptable part similar to the CNC milled version.
The flat aluminum bar I designed does not take up much space or weight in the tool kit.
I have found a $300 VFD to drive my lathe motor.
