Understanding How To Use Change Gears For Threading On A Grizzly G0602 Metal Lathe: Part 1

- I wish that this video had been in existence when I procured my lathe a few years ago. It's a bit of a mystery, and fairly simple once someone has explained it to you, or you've spent enough time messing around with it to figure it out like I have.
For Metric, Standard, turning, and a brief Glimpse at the left handed thread modification, and another modification.
This is all good info (and reverse thread option will work too) for the Shop Fox m1099 which is apparently a clone of the G0602 with slightly larger swing and longer center to center.
Thank you! I could not figure out what they were trying to tell me with those charts!
Great video. Really! Great idea about the last idle gear for left hand threads. However, normally one could use any gear size for the reverse motion. That gear does not contribute to a ratio because it is a single gear. So, for instance, for a complete revolution of the "a" gear so many teeth will have passed (45 in this example). Then, the idle gear will turn so much that the same number of teeth will move along its arc (45 teeth) and the same goes for the middle "c" gear, namely, 45 teeth as well and regardless of the size of the additional idle gear (as long as another gear could fit in the setup). At any rate, this is a great idea and gain the whole video is really good. Thanks.
Yeah, it doesn’t matter in that sense. However, if I’m going to have a backup gear, it might as well be one that I always use. It’s also the biggest gear that I use which is useful since the structures that hold the gear need to be pushed far enough away to not interfere with everything else when not in use.
Yes, that makes a lot of sense! Thanks for the reply.
Thanks for the vid. I have this model and only use it when i need to make a part which isnt too often, and i am VERY green when it comes to machining. Haven't had to make threads but knowing about it, kinda makes me want to turn some bolts.
thought this was going to be a mark felton video
Thanks....great instructions....😎
VERY useful video, thanks for posting it. I would like to mention one thing though, and that is your setup for reverse threading. You don't need to go buy a second 127 tooth gear because any size gear (that will fit) will work. It is what is called an idler gear, and its size or number of teeth will not affect the ratio and torque values between gear 1 and gear 3. I know this might sound wrong, but trust me I know gears...I am a clockmaker. Another advantage of using a gear there smaller than 127 teeth is you can find one that will let you close the door.
@@HarderThanCalculus I’m already aware of that. Smaller cogs can’t be used because the center isn’t pushed out far enough - the mounting device for that gear wouldn’t be able to be located in an empty space.
Excellent! I just bought this model. Thanks for the video!
