Nice!! How many hours do you estimate to complete all the links?? Are you going to make new pads as well??

Just an estimate but I think I have about 22-24 hours. I have a good bit of unnecessary machineing, like changeling my retract heights and feed heights that I could even get time down more. I don't have a tapping head so I'm tapping them by hand. But that is pretty easy and just a couple seconds per hole. I am not planing on making new pads and am still debating about cutting two small reliefs for links in them. Just like the 1:1 machines. The links curl fine but they don't curl backwards any because links hit. Not a big deal but it would be a simple thing to do.

Did you program the "Y" axis wrong or locate? I see some holes that look like they're in the wrong place. Or, is the tiny drill bit wondering off center from sticking out of the chuck so far? If so, add another event with a spotting drill or center drill that is more rigid then come back and finish drill.

Steve, in the first pic the divots are in the vise jaws. I drilled .05 past the part. And the jaws are only about 75% of the width of the part in order for the other jaw to clamp onto them. So if looking at that pic it looks like they are off but they are in the right location. The second pic shows parts in the jaws and were machined where they should be. And the orange strip is just a piece of vinyl tape to take up any slight difference in part sizes so all parts were held firmly in vise jaws. I did use a spotting drill 1/8" 90^ point at .04 depth so not to enlarge the holes for the #50 drill. The holes came out perfect, no wondering of the bit. At least from where I'm looking . Lol!!!
