[PROJECT] X Power Feed

[EdK]

So I've got started on the power feed for my mill and am looking for opinions on making the lead screw adapter. Without modifying the lead screw, I'd need to bore a 3" deep, 17mm diameter blind hole in the adapter to fit over the existing lead screw. That sounds iffy for me so I'm thinking of cutting about 2" off of the lead screw that sticks out past the table and then I'd only need to bore a 1" deep blind hole. That hole needs to be a good fit on the lead screw shaft so it's as concentric as possible to the lead screw so the power feed doesn't bind. Either way, I'll be pinning the adapter to the lead screw with a spring pin. Any reason I shouldn't modify the lead screw and make it easy on myself?
