    ; I am trying to figure the picture out, my screen is seven feet from my face (my problem).

    Is this post fix or doing the fix.

    Either way, thanks for posting.

    Now please describe the operating. Chuck jaws right? Interrupted as heck, internal cut?

    Splain yerself please JR

    Ohh! The JT! Duuu. Solly. Still. love to hear the op. JR

      The Gib seems straight by the way.

      Good answer Thats cool and thanks for posting the how to. Unfortunately most of my machines have cast iron I think..

      Now go feed yer dog. JR

      I have had a bad go around with gibs in the last 20 years. Breaking, wrong size, wore, dropping in hole, losing and on. I take machines apart and find broken gibs sometimes.

      Gibs are my bain.. JR

        I agree, prolly a component rather than a grounding issue. But just like you know engineers dont always account for ground as well as they could. JR

          The alternative is the horrendous costs and suffering associated with motor vehicle accidents.
          Humm. Sounds about right. studs are a common place item where ice is a constant danger. Chains dont do as well as spikes.

There are no safety inspections. I used to hear people driving around on them in the summer, they were bloody loud.
            Yup, I remember hearing the studded tires on dry roads (Oregon and New Jersey) and it was tearing up the roads. Thats why they are not used much. Irresponsible folks. Plus, we are not talking about the Baltic conditions here 73 today in Calif. JR

              It goes about 115mph.



              Nice! Is that electric right now? I used to fly a bell 47. JR

                Yes, Electric Ducted Fan. 25v battery pack, draws about 100 amps. Split flaps, retracts, lights.

                • I made up a MT3 holder for a couple of large center drills I have that was used in Face & Center machines at Eaton. The way the flats was on the drill would not let it center in a drill chuck. The problem was I was a bit lazy and drilled the hole instead of reaming it. So the drill floated and wiggled when used. So I bored it oversized and made a bushing. Here is the video

                    Sweet looking plane ! I played with glow ducted fans several years ago. I have a friend that has been into gas turbine models for several years, his are the 40lb thrust class, think he has 3 now.

                    • Took the new portable bandsaw found to a friend's - well, it is portable - and made short work of taking off the ends of the tubes that made a handle on each side of the monkey bars in his kids' climbing frame. One kid had grown tall enough that he was about to brain himself on the dangerously finished tubes. Hacked 'em off, deburred and sprayed it with a rattle can just before the rain set in

                      The put together a foot switch for the bandsaw. Just need to make a table and some sort of vise mount now.

                        Turned a scrap piece of 10mm rod in a lathe so that it runs true, tighten the drill chuck into rod, bore the internal tapered hole to run true.
                        Sort of backwards method to solve runout but that is only way I have seen and wasn't able to figure out better method either myself. Grinding or turning the jaws would need some clever way to preload them.

                        Edit: to embarass myself before anyone else points it out I admit that I considered 3 equal sized blocks placed between the jaws and preloading against them but I didn’t have anything suitably sized stock at hand.

                              The faster they go, the better it is to be big, so you can see it! That EDF of mine gets tiny very quickly, hard part is keeping orientation. If it was twice the wingspan, would be twice as easy to fly. My gas turbine will be a larger one.

                              • I was gathering parts for some time and trying to get the shop ready for some heavy fabrication. After running 400amp service to the shop the next stage was to adapt to three-phase. I found a brand new Baldor 40hp motor in Alabama from an EBay auction for cheap because of a missing fan shroud and a cracked cooling fin, probably damaged in shipping. It spins nice and easy and i see trashed three-phase motors littered all over around the quarries I haul in and out of so it's just a matter of time before I find a fan shroud. Another piece was when an extremely donation was made to the cause in the form of an old American Rotary 40hp control panel was given to me by an extremely generous individual. So the next step was to weld together a cradle to marry the control panel to the Baldor motor.



                                I really hate this Snap-On/CK MIG-welder. I can't get the settings right so it burns in right without popping. I really miss my old Millermatic 252.




                                Next was a trip to the local auto parts store to find rubber isolators in the form of motor mounts. It pays to know where the old-timer auto parts store is where they have patient old dudes with books instead of a kid that's lost when you can't give him a year and model of car to type into his computer.




                                With the isolators bolted into the cradle, the cradle bolted to the floor and the motor bolted to the isolators, what's left now is to wire this all up.
