Repairing toolpost of the lathe

I was supposed to start to do other side of spacer of springer. Lathe said No, No! Toolpost of the lathe was loose and the bolts, which keep it still were lost threads. Both! Did not have that kind of bolts, so have to invent something different.

Both side have these.

Here is one faulty one. Both were dead.

Bolt locks itself into these rails.

Here´s the start of new ones.

Too thick.

Have to take 2mm off.

Ready for threads.

One ready.

There it sits.

Works as planned.
