  • The things we do for engineers...

    A guy needed 6 holes to press fit these little discs into for spray coating. The discs are very fragile (I broke one on accident), but need to hold in there well. I figured the only real solution was a tapered hole. I don't have a CNC, or a Tree taper boring head, so I did my best with what I had. Got'r'done.

    • Some kind of shafts from 5" X 1" wall steel tubing.
      26" was turned to 4.488" +-.001", stopped at 4.700" to check diameter and taper and it was spot on, the finish was nice for mild steel tubing. 2 parts in total.

      • Spent a bit of time this morning laying out a new countershaft for my Ames lathe. At some point it had been converted over to a single cogged belt (timing belt) with a fabricated headstock, most likely for some high volume work. I'm almost ready to re-attach the original headstock, but since the countershaft was lost at some point I needed to reverse engineer a new one. I got my hands on some cast iron caster wheels to use as flat belt pulleys with some modification, and had to lay out the shaft to make it all work. Hopefully up and running in the next month with this setup.

        • Made 3 simple parts yesterday, 2" OD solid bar stock in 316 stainless, the largest finished diameter was 1.60" X 15 3/8" long drilled 1 1/8" diameter thru.
          This was a rush job so I asked my employer why he did not buy 1 3/4" bar stock which would have been perfect.

          Certified Material Required.
          It was all he could get on short notice, if all he could buy was 3" Dia. stock I would have turned it to 1.6" diameter and would still be doing it right now probably (-:

          • 3D resin printed a B8 control grip for use with DCS World. It's slightly different from most B8's as it added a button to the right of the hat switch as well. Apparently this version was used in Cobra attack helicopters.

              That's a what? Looks like a bong.

              • 3D printed a DS1348 decabulator for releasing the trunion pins that hold a biangular lasomatriculator in position, these are very similar to P-1093 decabulators but do not rely on Lansing wings as the 1804 SPQ does, a much more robust design.

                  I need to paint it.
                  F4 Phantom control stick. Or A10A, F5E, UH1 Huey, etc. The worlds most popular flight control grip, better known as B8.

                      Ol' 3 phase was a programmer, not a machinist. And not from joisey.

                      Bented is an original.

                        you have quite a small toolpost on that machine. what is that, a 1" tool?

                          Bleary-eyed first thing in the morning, at first glance (on a small screen) that's so not what I saw....but then maybe I just have my mind in the gutter.

                          I've finally made progress on repairing my tailstock. Those of you with REALLY good memories may remember me asking about it. I checked, it was only four months ago....quite quick for me! Got the broken casting milled out and a new piece of steel squared up and cut to length. It's a lovely fit. Just have to cut a number of clearances and reliefs so the top part of the tailstock will fit and then test it.

                            Aloris DA, I think that they will hold 1 1/4" tools.

                            Heavy beasties as well, a 2 1/2" diameter boring bar on a hoist because I am a lazy bugger (-:

                            • I am upgrading my security surveillance system. I replaced the DVRs with more modern units that have NTP ( time sync protocol ) and take 4 TB hard drives. I am using this opportunity to hard mount all the gear, hard wire and dress all cables, make it into one unit that can be detached and set on the floor when I need to make alterations. this unit will be mounted low in the back of the rack.

                              as always, mission creep set in. I have extra solar panels and charge controllers set aside for future projects. I have inverters. I have 1 in 4 out distribution amplifiers. I have TV RF modulators which were already part of the system. it ended up with some components on a higher shelf, facing front. the bottom shelf generates and records video, the top shelf distributes it.

                              todays task will be to finish an interface panel for the 1 in 4 out amps. these amps let me split the output of certain critical cameras to a DVR channel, an RF TV channel, and an output on the interface panel. input and output on the panel are a BNC connector and an RCA connector, tied together, so either but not both feed the amp. the output has the same arrangement. this lets me feed my most important cameras directly to my best monitors.

                              today: drill the mounting holes, blacksmith a 90 degree bend into a blank cover plate for a 4X4 box, paint, and populate with connectors. maybe solder up the very short cables to the distribution amps.

                              near future: use a thing called a RigRunner as a distribution point. feed the system with a switching power supply, and with a solar power system with a backup battery. it's all here, just a matter of mounting and wiring.

                              • Started and almost finished this little slide, I was down to drilling the mounting holes for the bearing blocks and then realized I didn't have an M3 counterbore....yet.

                                I just need one more tool,just one!
