Scrap Built Rotary Table (Part 2)

- In the second part of my scrap built rotary table, I make a hob, hob the worm wheel, and make the worm.

I promise I'll still mostly make stuff out of rusty junk and not just buy shiny things with your money.

"but, this handle looks phenomenal now..." My only regret is that it's taken me this long to find this channel...
Do you get a free tetanus shot where you get your material?? 🤣
Oh thats some really nice scribe lines you’ve set into that soon to be formed worm gear … 🤔 0.005” per pass finishing at 0.045” ok 9 passes 😓 thats a lot of effort but were finally ready right? … ok now just 71 more to go 🥺 … after a total of 648 Passes -> ok lets finally get to hobbin’ this worm gear 😵💫
Watching these videos just cracks me up sometimes as a little too relatable to my own experiences. 👍
The problem of tearing the threads as you progress is down to the starting diameter of the workpiece, this is larger than the finished root diameter of the threads so the thread count on the surface is greater than at the root of the thread, being two different diameters. I generally partially cut the groove
esess in the workpiece first on the lathe, then the only cutting is just over the depth of the threads and nearer the finish diameter, it also allows the hob to contact more of it's diameter so not loosing track. Still a good exercise, and enjoyed watching it.
Wow, that is one ambitious project, well done, and the filming & editing on top.
I'm tired just thinking about it 🥺
so,so much more interesting that you make the parts to make the parts (and reuse scrap!) instead of the more usual "I bought this from ..." thank you and please keep the projects coming :-)
Could you have used some small ball bearings to measure across with your mike? Kinda like 3 wires
Cut 2 pieces of round stock and place them in the threads ans use the outside mic to measure the total diameter. Now subtract the diameter of both pieces of round stock and you have your diameter.
Где такой материал то нашли? Он с Титаника что ли, на 16::00 видно особенно.
17:09 I also tend to strategically resize many parts, always down, as a project progresses. Great minds think alike I guess. 😆 Awesome job, awesome video, and awesome positive, chill attitude towards the difficulties, mishaps and hard working. The videos maybe don’t give this perception , but a project like this is very VERY hard work, that not many people would tackle as gracefully. I’m turning in a huge fan! Keep up the positive attitude and awesome work and stay safe!
Instead of solid pins to "secure" the gear, it would have been better to use a set screw or some such, as to stop, not only twisting, but also movement along the cylinders length.
There are anvils for micrometers that are round tipped blades. They reach inside the threads.
The groves in the hob need to be on at least a 20 deg spiral so as to track.
Nice. I enjoyed. Onto part 3. Man, I'm really liking this build.

when making the worm wheel it would have been better to have cut an annular groove with a radius = to root dia of the worm for more contact area when in use and during the hobbing process. 100% for effort and persistence. binge watching your other videos

Good job Jeremy, you have a lot of foresight & Eye for detail 👍👍👍👍👍👍👍
Thant handle does look phenomenal 👍👍😂👍👍. Very inspiring work here.
Wow! Home hobby hobbing. I’m in the right place for sure.
Very impressive. Thanks for sharing.
Definitely came up with some interesting scrap to use
👍👌
Looks like your live center is wobbling ! Is there a rigidity issue there ?
The lathe is old and worn, but the tail stick rigidity is good enough when I’m not asking it to do something it wasn’t meant to do.
