Double Bypass Tavern Puzzle

Great item

Now that I know how to work it there is a point where even if you know how it's difficult due to the shape of one of the parts. If the part corresponding to the "bow" on the iron heart puzzle was shaped like the part on the iron heart puzzle it would be easier to work. The steps wouldn't change but the process would be easier. As it is I can't work it without the parts binding up and requiring a good bit of force, which I don't think was the intention. Maybe I'm just missing something though.
