Today was several projects, I spent a total of about 5 hours in the shop. A rare day for me to get that much time in there!
First order of business was to broach the 6mm keyway on the change gears I'd made and had a fellow PM member cut the teeth. I had borrowed the broach from a shop owner friend of mine. I had pinged Russ via text last night hoping he might be working in his shop today. His arbor presses are usually open and sit near the door, but alas, this was one of his few Saturday's off in some time. Here's the gears and the broach, with the broaching bushing I made last night:

Well, I guess it was time to clear out some junk from the 10'x16' shed my dad had built about ten years ago, just outside the shop. Mostly woodworking machines and supplies in there, plus yard work implements. The arbor press he'd bought back around 2002 is buried in the corner, been used just a couple of times. Here's the arbor press. Not too bad for a Chinese version of what I'd rather own but can't find at an affordable price, a Greenerd!

After I broached them it occurred to me that none of the gears which came with the machine have any identifying marks, so I saw fit to stamp the number of teeth on each one I had made. Yeah, I double-stamped the 70, no big deal because it'll work. And the results:

After I'd got all that done I started back to work on Neil's custom motorcycle pieces. I milled the hex on the long axle I'd made a week or so back, then Neil showed up to help. We had three different length bolts to make, two different thread sizes. I turned the 2 longer ones while he watched, then set to milling the hexes on those while he made the shortest one. These came out beautiful in 316 stainless steel. Though tough to work with, it's gratifying to see how pretty the parts can be. The original steel ones had a concave recess in the heads, so I took a 1" 2-insert carbide ball end mill I have and centered it in the lathe. I put it in a boring bar holder for the QCTP, swept it into concentric with the spindle and plunged it into the ends of the bolts. It did leave a little pip at the center, short work for a round mounted point (grinding wheel) in a Dremel.

The shortest of the bolts was too short to turn around in the chuck to cut off the center hole and face clean, so I quickly made an aluminum bushing and split one wall with a hacksaw. ten minute job, done. If I can get back over there tomorrow I'll change to the metric threading setup, remount the collet closer mechanism and thread the bolts.
