I have a complete stock kit here I am assembling.
I am going to move to a 12’ top beam, but I don’t have the right chain length so I’ll be building it at the original 10’ to start as I want to get cutting and learning. Assuming I don’t also change the bar height, and I otherwise was “in a vaccum” accurate with all the other positions of things, then what should someone reasonably expect for accuracy of the stock kit in stock configuration (best case scenario)?
I do realize that accuracy changes near the corners and middle of the top. So perhaps the question should be, if we call those “accuracy keep-outs” what should the accuracy be in say the 3’x7’ “middle” (or is the size smaller than that where accuracy should be extremely constant with the stock setup?). To whit, I can comfortably put roughly 6’6" x 3’6" in to my vehicle with the gate closed, so I’m especially interested in how accurate I might be other that reduced surface.
I’d like to have a baseline so I know what to expect when I pop out the other end, and that I can compare to as I implement suggested upgrades. I’d like to contribute to the body of knowledge on how different changes influence accuracy and I hope to have some time this summer to contribute and do a bit of testing and comparison.
