G. Gorton Rotary Table Repair

[Janderso]

I started this on another thread, this one seems more appropriate.
I’m in the process of fabricating a cam lock and plunger to replace the original broken/repaired/broken part.

This morning I finished milling the plate to size and bored the hole to 1.500”.
Next step, mark and center punch the plunger hole.
Then I need to layout the cut for the slitting saw.
The order of operations is getting interesting.

Nice looking table, there, Jeff!

I'm thinking to make the plunger column, I could turn down a piece on the lathe, TIG it onto the surface of my plate before I remove the angular mounting surfaces and mount this pull stop.
This project is probably clear as mud.
I'll post pics along the way.
Drilled the pilot hole for the stop but left it there until I had a plan that I could count on.
The plunger that came with the RT is the original, I'm tempted to cut it down, thread it and use it.

If it were me, I'd make it as much like the original as possible; could the column be cut from the original casting, the end turned down and fit into a hole in the new plate?

Interesting idea, I think I understand what you are saying. I don't think I have the expertise to pull that off.
Baby steps John,
My design will provide the same locking function but it will be of new material. At least i'm not using wild fire steel. I decided to use some cold rolled 1 1/2" x 4" end cuts I found at All Metals. I think it will work just fine. I'm going slow and thinking it through.

Received the pull stops. I decided to use the 3/8” design.
Now I can get back to repairing the RT.
Three day weekend coming up.

Making some bushings for the pull stop where it locks into the housing.
Received the pull stops.
Making progress.
