Transport screw testing



This transport screw has been working well, much better than the other hobbed bolts I had made. This way of making the drive screw is a lot more consistent and quicker to make.  I'm making a cut area of about 22mm, this way the bolt can be put in either direction, with the head in the gear, or the nut in the screw. The head in the gear seems like it makes more sense to me... I tried a cut area of 20mm, this works, but when I added two washers just behind the large gear a small amount of uncut threading could be seen in the idler wheel hole, 22mm seems to be just right.
