Au contraire, mon frere!! That is not dog food, but rather bear bait!!

Here are two pics. I didn't put feet on it because I just wanted to see if it would work and I am probably going to take it to the cottage. Does it work? In a word yes. I have that string to a point that I ususally take my strings, tighter than a ducks aaaasssssssssssssss LOL!

The string is so tight in that picture that it makes loud noise when you run your finger nail across it. I am absolutely sure you can break a string, I said you, cause I don't like the fuss my wife made when I broke a dacron string. She thought a gun went off!

are those jigs for doing servings only or, can they be used to make strings?

Hey John. After the string ends are done you have to put tension on the string and twist it at the same time making the string the length you want by twisting. After that you take the string off and fold it in half and mark center. You can then put it back on the jig to serve the string. So yes it is for making the strings but only the end process and to serve the string. Its hard to understand unless you've made a string.

Has anyone tried to make this contraption yet? If so what do think?
One thing I forgot to mention is to lubricate the threads with something. Anything will do. I use neversieze or coppaslip, both are antiseize or anti-galling agents. The purpose is to not wear out the thread too fast. Just a tiny bit is needed.
For anyone making strings too lubricant will cause other problems. Too much will allow the string to unwind. If it does just attach a large pair of vice-grips on the unthreaded part of the hook shaft and angle it so it catches the frame.
