So I'm going through the Atlas mill finally. when I got it, the entire gear box was gutted and missing, the lower u-joint for the table feed was broken and the handle was broken off the back gear knob. I got a gear box a while back but have been procrastinating on the project due to the back gear knob mainly. It's a concentric knob that rotates the back gear in/out and they are a common breaking point being pot metal. Mine had fused to the head prior to my owning it, I'm assuming that's why the handle was broke off. There's a seller on eBay offering newly machined knobs for $80 or so but I figured if I could get the bushing out, I could make one myself god cheap or free. It took me a while to free the frozen, fused knob from the head and get the shaft out without further destroying it. Once I got it out, I quickly came up with a plan. I found some bar stock close in diameter to the knob's bushing and turned it down to size in the lathe. After I got it sized, I cut it to length(over) in the band saw and faced it on the lathe. With it sized and faced, I offset it in the 4 jaw chuck the same distance as the bushing, center drilled and drilled to size and reamed. It fits, it works, now I just have to cross drill it for a roll pin that hold it to the shaft in relation to the bushing on the other end. I'll have to come up with a collar with ball bearing detent or something to hold the two factory positions indented into the head. More to come, hopefully have this thing running this evening.
