  • A little jig

    A little something I knocked up.







    A virtual pint for the first correct guess as to its purpose.

        Looks to be a cute little 70~90 degree angle plate setup.. Not sure why that saddle part rotates it seems...

        Whats up with that blue metal?

          You mean bu**er Paul, you've just cost a Chiwanese a bowl of rice and fifty tool gloaters 200 pages of moaning about the demise of the "Old" manufacturing industries.

          Good simplistic and effective toolmaking though.

          Regards Ian.

            It was cold in the workshop.

              Funny, it doesn't look pregnant yet.

              How do you plan to set the angle?

                That would be giving it's use away.

                John is the closest so far.

                  Some time long ago, I built a jig like that to do second spark plug holes on the mill.

                  Mine was a lil different thou, I fool with older junk with a five hole head.

                  You see the jig to hold the cases "off mill table" to make up for boring for a big bore kit? them are old pre-evo junk too.. someday they'll hit the junk truck with a thump.

                  I have rode Harleys since I was 18, my first being a BiCentinial shovelhead, my current a Evo, I have worked on them evos and they have a few quirks. One of the best engines HD has ever built. I am not a fan of the twin cam.

                  If it was the 1900's I'd be touting the advantages of a leather belt drive tho. I still want a Hayabusa. For a day. or ??
                  Excuse me, I farted.

                    Are you going to doing your own valve jobs ( cutting seats ) ?

                      Yes, but not with this setup.

                      Try again.

                            Intake or exhaust jig... to either open up or drill mounting studs. Or mill the fins away for contouring from a shop built piece.
                            Wow... where did the time go. I could of swore I was only out there for an hour.
