 Hydraulic (Metal Finish) Question

When folks "make" hydraulic cylinder surfaces, I am curious what the optimal
finish is... We are thinking 6-8 Ra, but some have said even finer is
necessary...

We want virtually no weepage and certainly no leakage... Pressures not to
exceed 250 PSI.

Anyone have lots of experience with this and a definite answer?

I was thinking more along the lines of "lack of contamination." <G>

There is enough of a market out there, and enough foolish forklift drivers
that my machines can be built to last forever and I'll still get repeat
sales and parts orders.

There's not a tool in the world that can withstand a blow from the "foolish
forklift driver from Hell" for under $10,000... (someone will be along
shortly to prove me wrong I'm sure)
