      • Shaft from annealed D2 tool steel, 2" Dia. X 110" long with a 1.500" +- .002 X 3 1/2 long journal on one end and a 1.437" +-.002 X 7" journal on the other end with a 5/8-11 threaded hole for an eyebolt to allow dipping in vertical quenching bath. It is hardened, straightened then centerless ground to 1.999+.000 - .001 after hardening.



        After facing and centering.

ID:	1860338 Made a new cursor for my spin indexer. Also ground it a little closer to parallel and perpendicular. I did it back in the mill-drill days, but this is better after the surface grinder. I'm going to key the hole plate to the spindle, also.
            I cut it off twice; it's still too short

            • Not today, but Wednesday night I made some tie down plates for some can-am Linq brackets for an atv. Scanned the brkt and drew some lines to follow the casting. Some scrap aluminum, Simple 2.5d program, 2nd op facing to 0.25", and some scotchbrite. Tapped the hole m5, but only had 25mm long screws. Found some 10-32x1/2" ones though, so was all good. Just a quick and dirty gov job for one of the guys at the shop next door. The only request I got was "can you make a hook or something on here I can hook a bungy to?"

              • Another project from the recent past is some more expanding collets. Made 2 of these guys. Main body was the same size, but collet dia's are different. Collet and wedge were 4140-ph, but the body was just normal 4140 I roughed out and send out for hardening, then hard turned to final dimensions. I love hard turning . Only the pilot for the wedge and body dia's (sits in a vee block on the main fixture) were "critical". Made a special fixture to hold the collet and prevent chatter and cut them in a haas 4th axis.

                All manual turning/machining aside from the collet slots. There is a 3/4"-10 shcs up the middle to draw the 4* tapered wedge down. Also a couple 1/4" dowels into the face of the body, and the side of the wedge to prevent rotation. I didn't design it, just made them to print.



                All setup and ready to cut the first one. You can see on the tail end the centering lip I cut to register the collet body. The end plate is reversible for the different diameter collets, but on the face plate I started with the big size, and then recut it for the smaller one.

                Finished the 2nd one. You can check your math over and over a hundred times, but it's still relieving when the 4th comes around to finish the last slot and it's where it should be and not on the same side as the first one lol .

                        • Made a couple of seal drivers for installing seals in my transfer case. I just made them for the two 2-part seals, which are annoying to install using large sockets as you need to switch between two different sockets all the time and risking damaging the seal by pushing in one part too much relative to the other one:

                          One is flat, the other has a lip as the inner seal isn't flush with the outside seal.

                          • Made some bushing/bearings for the street clock and polished the shafts that fit in the bushings. Ordered 250 feet of 1/2 x1/8 steel for another project. I am sure glad I have a shop to work in as we avoid other people. The added benefit of getting paid to hide in the shop makes it even better.

                            • Hi Stepside,

                              You are still being a BIG tease without pictures of what sounds like a truly awesome project.

                              Pic's Please

                              • I got a bee in my bonnet last night fairly late after dinner and did a bit of lathe work I've been meaning to do for quite a while.

                                My main press is a Dillon 550 that uses a particular Dillon powder die. The Lee dies I use come with a shorter powder die that I can't use directly.... But NOW I can...

                                In the first picture below a regular Dillon powder die is on the left. In the middle is a typical Lee powder die with the three parts. And on the right is the Lee die modified with a glued in bushing which is now compatible with the Dillon flaring insert seen on the left. I did three of these last night.

                                Operations to adapt the Lee die is as follows and which you can see in the second pic of my shop design book for the project. Steps were;
                                • Drill out Lee bodies with 9/16 drill bit just a little shy of the bottom nose to match the Dillon dies. This lets the Dillon flaring insert fall in the proper distance..... but not out the end.
                                • Bore out the threads in the top of the Lee body out to allow the tail of the new top bushing extender to fit. These were glued in place with Loctite 680.
                                • Set up a regular cutting tool and a wide slotting tool to produce the bushings from some 1" leaded steel bar stock I've got on hand. There's some scribbles around the bushing showing the first "0" cut for the grooving tool and then shifts from that to obtain the other sizes. That made producing the bushings a nice quick and repeatable job without needing to sneak up on all the measurements.
                                • Drill through with 9/16".
                                After that I glued the bushings in place had a bit of pie for late desert, watched a bit of Netflix and then went to bed knowing I'd done good....
