I would like to extend my lead screws so I can put knobs on them to more easily turn them manually. I need 8mm, 2-Start 2 mm pitch (4 mm lead). Does anyone know of a source? In all my searching most everything I find are 4-start. I am able to find* the longest stock length for my machine (x-axis, 365mm) which would not be long enough to extend out for the knob on the x-axis. Does anyone know of a source for this part except longer?
Not to me, but in any case pictures often aren’t representative…
No guarantees, but I’ve gotten overall better quality lead screws recently than a few years back. The biggest problem I experienced in the past was screws that weren’t straight but it’s been a few years since I ran into that problem.
