Hi all,
I have just about finished my first CNC machine and received the Acme screws from the USA today. Both screws (36") have bends in them of about 1/4"- 1/2" over their span. What is the best method i should use to straighten them evenly, and will their accuracy be affected? Or am i just worrying too much?

Thanks kindly in advance,
Julian.
Ps. I will post some photos soon of my machine
