Hello.Wes.
Would you mind showing some pics of the change and where to set a stop?
I own the similar mill and I'm working on a riser.
Looking at the nut of the mill's knee causes me to worry.
Cheers,Ralph

Hey Ralph,

Sorry I didn't get any pictures. When you raise the table the screw also raises. If you go too high the screw will come out of the nut. You need to measure your screw and calculate how much you can travel. I would suggest buying a new screw and making one 6" longer than the original.

Good luck:o)

A Gismo ??? If it has a flywheel or spins and is made with small parts. I'll take one! If it makes noise, moves, or requires frequent oiling and dusting it's a better deal yet. It's especially right if its shiny and bright; but if it's dirty and dull it wont mater at all...

Hello,Wes.
I should tell you that Acme threads are not very common in Germany.
Can you tell what size it is and if it's a stub Acme thread or just an Acme?

We got something similar that is called Trapezgewinde.

Due to the fact that I own a Myford and therefore an imperial lead screw,turning an Acme shouldn't be a problem in general but the necessary length will most likely bring me in to trouble.
You see,it' s not that easy to follow your suggestion.
Sometimes,buying is the better solution,but there is no seller of Acme rods around,afaik.
I think,I will change to the Trapezgewinde.
Rods and nuts are available at Maedler.

Anyway,thank you.
Cheers,Ralph

If I remember it's a 1" - 8 left handed acme. I bought mine from a big place called McMaster Carr. Here is the page. http://www.mcmaster.com/#acme-precision-lead-screws/=hce2jj I hope this helps.
