Hi all,
Seeking some guidance on a fixture to assist in machining the slots / channel in a new custom oversized pivot pin for my BCL 102.
I am told by SFRC that the front pivot pin is proprietary to BCL so finding an off the shelf oversized front pivot pin is likely not going to work.
Turning the round stock to the correct OD is obviously not the issue using my lathe. I have turned several that I have then screwed up as the problem I am having is machining the longitudinal groove / slot for the detent retention pin.
I do not have a milling machine and have tried to do this using the tool compound using shims (the part rotates and I do not get a uniform cut) as well as the milling attachment I adapted to use with this lathe and am having the same issue with the pin rotating when using a mill end in the chuck.
The only solution I can think of is boring a square bar or old cutting tool lengthwise to the correct ID so the pin fits in, and then machining a wider slot in that square bar to access the pin with a mill end, and drilling and tapping screw holes in the square bar to use set screws to hold the pin in place so I can Mill the slot / groove for the detent.
There must be an easier way.
Anyone have any suggestions?
Many thanks in advance.
