    I can't ever seem to be happy with my machines-I always need to take them to the extreme. Well I have decided I need a 1500mm wide machine so I can cut cabinet fronts and panels out for making more storage in my shop. I have found one source for a 1500mm 1616 ball screw, and I ordered it up-but it seems to be stuck in customs (from Canada eh). I actually purchased from their ebay store, since the exchange rate made it cost less than ordering from their web store. https://snbinc.ca/store/ On a side note, these guys have acme tr8 stainless steel in 1500mm lengths, but I think the whip on that would be pretty bad.

    I'm really not sure that a 1616 screw is going to fit well on a c-beam gantry, will most likely have to cut new plates for it. I don't recall any c-beam builds running a lead screw, someone correct me if I'm wrong.

    Has anyone found a source located in the U.S.? What I'm really looking for is a 12mm acme style, as I have a few builds going that could use a standard style lead screw.

    Well I guess the same guys I ordered a ball screw from also sell tr12 screws...Doh..

    Still looking for a US supplier though. There are a couple tr12 lead screws on ebay, but that does no good since there are no end supports or lead nuts to be found...

    I used the McMaster Carr 1/2"-10 5:1 for my 1500 mm lengths. I don't notice any whip problems. I made my own anti-backlash nuts from a 3/4"x6"x6" delrin block I also purchased from McMaster Carr, by making a tap from the acme rod cut-offs.
