  • gear cutting fun

    Probably not as perfect as someone could have done with a dividing head but should work well.

    So what did you use? it looks good,

    maybe have a little character sound when running, like a yahninininyahninanahyahninininyahninanah

    can actually be very soothing...

    and sandals and machining? excellent choice

        HAHAHAHA yeah it will probably have a little character when running as i'm sure its not perfect.

        I basically used a bolt in a sort of jig to index the original gear. I centered the gear using the gear cutter and then moved the bolt / indexing thingy into position. This allowed me to then spin the gear after each cut was made and index the teeth. Kinda hard to explain but cheaper than buying an indexing head or filing them out by hand.

        One of these days ill come across an indexing head and not need to perform these hacks to get by.

        Anyways it should work and is kinda the poor mans answer to gear cutting

            It doesn't matter what you use4 so long as it does the job to your requirements.

            No need for an expensive rarely used dividing head as a good rotary table stood vertically will do the job just as well.

              yes it's interesting, I think the guys are going to want you to go through the procedure a little better esp. if it's dirt cheap to make...

              I just thought of something, what about so many holes drilled about 3/4 radius part of a gear, and then a solid mounted plate with holes in the same radius except one more - like the way porsche used to use very fine degree's to adjust cam positions ---- just a bolt hole calc. on your DRO and you can quickly build both - Im sure you would learn a pattern real quick for your spacing although would have to be figured for number of gear teeth and if the offsets would match up...

                OK.... so I'm not gettin it here..... how did you do the tooth spacing? Eyeball it?

                Or is that a brazed up repair, and you just indexed off the good teeth to cut the others?

                In that case, how did you get the spacing from the last good one to first to be cut? I can think of a few ways, some probably better than others.

                  It's OK Boomer! I've only have 9 toes, we can start a p toed machinist forum. It'll be worth cutting one off just to join!

                    Ill try to get some additional pics and better explain my process. Like I said it probably isnt perfect as you would get using a dividing head but should work. One of these days ill run across an affordable dividing head and not need to build one off fixtures for making these darn things.

                    At least this time I used an actual gear cutter.

                        Yes the brazed part is what I repaired. That area had missing or broken teeth, so i took a carbide burr and cut everything down to virgin metal then built up with braze.

                        Ill try to get better pics but yes I use the good teeth on the opposite side to index the gear for cutting.
