[TheForge] request for opinions (updated models)

Looking better Terry. I think, though, that a  small radius is needed where 
the shaft meets the head of the bolt to avoid stress risers. Not saying it 
couldn't  be made this way but it would create stress risers, and end up 
with the heads popping off. Normally there is a short tapered area 
between  the shaft and the start of the threads, then the crest of the 
thread should be the same diameter as the shaft of the bolt. I also think 
the end of the bolts look a bit off. On most bolts the end of the shaft is 
deformed by the force of rolling or cutting the threads, so it looks a 
little dished out.
Nice work, though.  I went through this once before in CAD training on the 
HP 9000 in the early 80s, and took me a week to work out how to do 
screws.  Haven't used it since. ;^)
