    The ball screws and nuts best is to get them from Fred BST Automation, as he has proven himself these years. 3 weeks ago i bought Hiwin from him for 2x 3d printers and he not only gave me the best price around/ i checked just to see the market/ but i had all in 5 days here in Spain.


    As far as the HTD5 rounding, Tom, you are right. I assume most of people will cut them on 4rth axis or indexing head. Anyway below pictures of the absolutely correct profile and size of the 30t puley. I have parametric model that have drawn of HTD5 so if sb say wants a 300T pulley up to specs just drop me aline and will send you a DXF. But here i include the DXF for 30T pulley, the passing hole 27mm and shaft 35mm, needed for the important part in the rotating ball nut. So you can base your drawings correctly.
