    My three point finish mower had a seized spindle. Once I got it apart I replaced the bearings and seals, but it still wouldn't turn freely. Besides the bad bearings the shaft was damaged. So time to head to the shop and see if I can make a new one. Success! 3/4-16 left hand threads on both ends, bored and counter drilled a grease channel, tapped for a grease zerk, and milled a keyway. It took me two tries and two days, but my deck is bad in service, so I'm thrilled!

    “Two tries and two days”.......hard to maintain the mystique in the face of such blatant honesty.

    Good job, anyhow!

    Was old shaft bent?

      Very nice.
      Two day's worth of work is probably still cheaper than an entire new spindle.
      Especially if it's painted green!!

        Thanks! Yep, shaft bent and no longer available. I'm still learning, but I'm having more successes than failures now in the shop so I'm making progress.

          Great job. The beauty of having a home shop and the ability to make replacement parts should put a smile on anyone's face. I made a complete spindle and housing for my swisher tow behind a few years ago, and the only thing I wish I did different is that I wish I made 2 more for the other ones at the same time lol.

              Great job. You will have a smile on your face while mowing. Hint, pick up the rocks before mowing next time!

                I took my bent shaft to a machine shop to get a new one made. They let me watch while the machinist mounted it between centers in the lathe, heated it to red hot, and then pushed it straight with a roller tool. Ten minutes done.

                  The learning experience was worth a dozen spindles bought in a shop. The more you do, the more confidence you will have to take on projects. Making scrap is one of the best ways to learn.

                    Maybe it was Confucius that said, "Machinist with not big scrap pile no try hard enough."

                      I turn all of my mistakes into piles of chips, and then pretend like I meant to do that.

                        One of my first lathe projects was a mower spindle to replace the one on a Yazoo mower. Dad had already had a friend make one, but he did a poor job. My first one was scrap too. The second one's bearing fits were eh, but good enough. It's still in service. My biggest regret was making it 3/4-16 instead of 3/4-10. Not many 3/4-16 nuts in the drawer and they were all crap.
