IMPOSSIBLE Miniature Internal Keyways and Worm Gears

This video shows the machining, fixturing and assembly of the worm gear mechanism inside the miniature lathe apron. The keyway in the worm gear is VERY small, but you'll like how it gets done. TAKE A LOOK !!!

At 17:34 while HAMMERING on a CUTTING TOOL in the MILL CHUCK, Joe said "I'm going to get a bit more aggressive." It should be noted that the tooling in question was 1/16 X 1/16 X 3/32. You wouldn't want that to be taken out of context. Another awesome job on parts so small they give me a headache.

[@ferrumignis]

A thing of beauty is a joy forever! When you were adjusting the broach with a punch I was thinking the cutter would bend sideways somewhat more easily than it would forwards (despite the relief), so it would be easy to accidently widen the slot. I suppose you just need to check alignment carefully before taking the next cut.

[@joepie221]

It did side bend once. I caught it on the next pass.

Never be afraid to push your limits or fail. I believe its how you get better at anything. Although this series is somewhat advanced, I hope the thought process and philosophy I incorporated can be applied to simpler projects. Thanks for your continued positive comments. I appreciate it.

[@garrattfan]

When you were making the broach it left me wondering how this was ever gonna work until I saw you bend it. Dear me, I never expected you to make a sacrificial tool. On making the L-key I think it would have been much easier to simply file it. As a modeller I have learned to file within 0,02 mm (7-8 thou) tolerances and I have a very small machine vise to hold it (1 in). But as to machining it your method was again ingenious to say the least.

[@joepie221]

The sacrificial broach worked very well, and the completely blind machining of the key was fun. You have to trust your numbers.

As I was watching, I was thinking about how much I have learned watching this build. My question is, and it's not a rhetorical one: What, if anything, have you, Joe, learned, while building this kit?

[@joepie221]

I had limited knowledge of these machines when I started. I really like the reverse gear setup and the feed worm designs. I have a better appreciation for the intellect of the 1800's engineers too. My steam engine was my first functional scale model and it was just a build. I took my time, but this lathe has my heart. I am going the extra mile on every step. So maybe I've also learned a higher level of patience. Good question.

Thanks again, Joe. Time well spent watching your videos. I am currently rebuilding my 9x20 bench lathe saddle so in a sense I'm doing something similar to what you are doing, on a larger scale. all of the holes in the cast iron for the gear shafts were worn so I reamed out the holes and installed offset oilite bearings, that I made, to adjust the backlash in the lead screw, feed gears, and rack and pinion gears. All in all, I modified & installed 3 bearing sets and the set screws to hold the offset adjustment and also installed new oil feed channels so the new bearings won't wear like the stock ones. Watching your project was a good inspiration for fixture methodology and had a myriad of good tips and pointers for general machinist practices. I'm looking forward to the final assembly of your lathe and watching that bad boy going round and round. As you say, "it's a thing of beauty".

Where I went to school, all the engineering students had to learn basic machine shop skills, on manual machines. Always thought that was a great idea, but never knew why. Now I know why.

2:01 There is a easy trick to get it run fairly straight in 3 jaws and 4 jaws -I loosely put it in chuck and then use a peace of wood/plastic/sometimes steel back end of knife-or whatever is avalable according to material i am going to cut hardness and i put it in a knife holder and slowly touch it while machine is running.Just make sure that peace you are using in a holder is above the center and that clamped peace isn't too loose or it may jump out . Works very well ,simple and fast.Some people made holders with bearings but i am way to lazy to bother with it.
