    Removing a Broken Bolt in Motorcycle Cylinder Head

    This video shows the effort that an experienced machinist goes through to fix a baffoon's boogered up handicraft.

    Nice video. That Abom79 guy has lots of great videos. He's a master craftsman for sure.

        what could be better to watch on a Saturday morning? ...'course I wandered off to "Haas Tapping tips" and then drills and then drill sharpener comparisons...A nice break from the epidemic.

          When you say "machine shop" a lot of folks picture what I would call an aerospace shop.
          Perfectly clean, big tool room with all the latest tools in every variation and CNC everything, cranking out parts to some theoretical exacting spec.

          A job shop is nothing like that. There is a LOT more sausage factory going on in a job shop.
          In a job shop it doesn't matter HOW you get the job done, the end result is what matters.

          This guy does stuff I disagree with, like in this video he is cutting into that head and the swarf is falling into the valve springs. NOT A GOOD THING! (Abom is a machinist and it doesn't matter to his job, the guy putting the bike back together might want to know about that) where all he had to do was ram a rag down the hole to catch the metal filings... but he didn't.

          Have you met Old Tony?

                Yeah I watched on of his the other day... a 6 cylinder jug made with not a lot of tools. Reminds me of the guys that used to work for me in a tool shop (press & Injection tooling). They certainly had some (under appreciated) skills

                I've always put helicoils in with red loctite to stop them backing out. I noticed he didn't. I wonder what's best practice....

                  His library of vids is a bit poorly catalogued.
                  What was the source of the head and cases and tranny? A KZ1300?

                    I didn't watch that bit yet... only how he made the jugs & the crank. I believe the whole thing was cut & shut from 2 engines.

                      Going by what he's done with previous stretches, to use off-the-shelf parts would be too easy.

                        Cipher, yes, you need to search for videos

                        No, he has a video showing how he made the head and one on the barrels. He takes 2 four cylinders, cuts them up and creates a 6
