I have several 46" long pieces of 1/2" pre-drilled linear shaft, hardened. Shaft ends are eased/deburred. I also have aluminum suport rail. I want to use them end for end to extend my x-axis length. I have not purchased the linear bearings yet. What sort of luck will I have aligning them end for end with the bearing running acros the joints?
Do I need to have the ends re-machined and dowel pins added for alignment? If so, can that be done with the shaft in the hardened state?
I looked through the theads on linear rail alignment and understand the need for an accurate reference line or edge for alignement, but didn't find explicit answers to the end-joining question. Thanks,
