You can't have two pivot points for the curl motion.

you can avoid it if you're willing to exclude *hand grips*  

 
edit: if you turn the diagram 90deg that fixes it too

next time you invent a machine try this method vince

This fella has a unique perspective about arm training. Google his youtube videos.

That doesn't refute my statement. My members tell me all the time how good the equipment is. In 1991 I attended the IRSA convention in San Francisco. You should have seen the equipment on display. Well, I returned to Australia determined to build a machine that was better than anything I had seen there. I designed and built a Hack Squat machine. It is simply the best such machine in any gym that I am aware of. This is just one of many original machines I have built. I use quality components, too, such as plenty of stainless steel, linear bearings, large pulleys, etc. The Hack Machine below is also a sliding calf machine.

to be fair those do look like decent machines vince. durable looking, and well made
