| Mounting End of Thompson Shaft |  |

I need a good way to rigidly mount the end of a
thompson shaft to a .375" plate, and secure the shaft in the
mount. It is currently mounted in a 5x5x2" block with a set
screw to hold it in place. The set screw does nothing against the
round surface, and the 2" block doesn't do much for rigidity.
The shaft basically sits in the block by its own weight.
See diagram at: I would like to machine the shaft to have a flat spot for the set screw to bare against. Or, even better, I'd like to be able to drill and tap a hole into the bottom of the shaft to keep it from bellow. Since these shafts are hardened from the outside I don't think either of these two ideas are easy or possible. Does anyone know a proven method for this application? |

Split the block from the bore out to one side.
Then put a bolt through the block that intersects the split. Then
the block becomes a clamp around the shaft when you tighten the new
bolt. If the bore in the block is sized correctly this will hold
securely.

Hey, that became a great idea. We'll use the
existing block to maintain current positioning, and add a 1.5"
clamp block to the top of it, using existing bolt holes. I think
this will do exactly what I want.
See solution at: Thanks a bunch! |

You are very welcome.
I love it when a poster comes back with results. -randy- The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them. |
