Re: M-Head Conversion Update

Wow, thanks for the info Jon, you definately know your "stuff". Do
you know what the best lube I should use? It looks like one of the
previous owners installed "zert" fittings so everything gets
lubricated but it looks like they also used grease. Is using grease
ok?

I will prabably use the MMI software from Aerotech. It will be the
only thing I have to get directly from them. I just couldn't pass up
the deal on all the other Aerotech stuff. It was quite a deal.
cheers.
