Thanks for the carbide lead. A push button was in my (super cheapo)

I'm going to modify a turret plate with a 1.375 square by real long

gundrill tool holder. Drill 12", back up and stop. Loosen holder,

slide ahead, restart drilling. I'd use a manual lathe but the hardinge

has a nice flood coolant setup and complete enclosure.

Ahhh, very clever that.

I would think your push bar problem is less about compression and more about bowing.
An uneven force will cock the button off center for a bad result...as far as I understand it.

I've heard of using hydraulic force to push a button through a (threaded) barrel.
I wonder if some type of a grease gun would have enough pressure?

Will look forward to updates on your progress.

I am still hoping to make a reproduction rifled barrel for my .177 air pistol some day.

Ah...I do have a gun drill available....shrug

"The socialist movement takes great pains to circulate frequently new labels for its ideally constructed state.
Each worn-out label is replaced by another which raises hopes of an ultimate solution of the insoluble basic
problem of Socialism, until it becomes obvious that nothing has been changed but the name.
The most recent slogan is "State Capitalism."[Fascism] It is not commonly realized that this covers nothing more
than what used to be called Planned Economy and State Socialism, and that State Capitalism, Planned Economy,
and State Socialism diverge only in non-essentials from the "classic" ideal of egalitarian Socialism. - Ludwig von Mises (1922)
