Hey man I have taken that server down, and after of almost one year of use (and abuse) of the grapple I have made some important changes on the CAD that are not reflected in the drawings yet.. I see you are very close to me, do you want to come and check the grapple? In real life its different than the CAD, and I can make changes if you want. I can also cut the files on my CNC plasma for less if you are interested
