Punching Hammer Eyes on the Hydraulic Press

[@philippatek3928]

Can you explain, or make a video on what you’re using for punch lube?

[@gearhartiron]

I used Hofi lube (powdered graphite mixed with dry molybdenum added to water and some dishwashing liquid)
to coat and cool the punch. Coal dust was used in the hole after it was started.

thats great, how many ton press is that ?, I only have 40 ton, but I'm going to work my way up to see my limits. Great idea ! !

[@lookitcrashed]

So a 25ton would work? Seems yours goes through it like butter.
