Has anyone come across an issue with assembling the Jotag dolly rubber bow rest? Apparently, you're supposed to dig a channel out of the bow rest to accommodate the nut that attaches to the bold that feeds through the dolly assembly itself. This seems to be a ridiculous design flaw. The rubber is very thick and it's nearly impossible to gouge out enough to put the bow rest back onto the handle after the handle is attached. Any fixes or ideas are appreciated. TIA!
