I guess the X3 R8 spindle from little machineshop would work. You could get the whole assembly from them, but it comes with a collumn, and its pretty heavy. You can also just buy the spindle and build a housing for it.
A couple questions about the machine. I'm curious.
How much travel?
Are the tubes welded togther? And have you filled them with something like EG, Sand, Concrete.. etc?
Looks big! Got any pictures of it? |
