Awesome video for the beginner! I’m retired and have always wanted to design and build things and after 12 months of doing some of the things I’ve wanted to do I realize I can’t afford to keep running to the Machine shop in town. This video has covered everything I need to do at this point! Thank you!

I think this video is meant for people who don't know anything about running a lathe. For that audience (which includes me) I think it is fantastic. Well done!

For a guy that has never run a lathe, very good instruction. Thanks

I am in first year Mechanical Technician CAD/CAM Program and mid terms have arrived. This video was very well done. You expplained it so well. Thank you.

My #1 Utube machinist class. Thankful for this great tutorial!

[@smithheart360]

These videos should be a requirement to view before purchasing power tools if your not a machinist by trade. Probably saved my fingers in the future.

[@utubetommy]

Ran an engine lathe exactly like this one years ago. Small lathes like this one are the ideal size for a home machine shop and what you can do with one is only limited by your imagination.

[@ydonl]

That's a Monarch 10EE - one of the most precise (and interesting) lathes ever made. Not exactly typical home machine shop material! But your basic point is quite valid.

[@ydonl]

​@@TheRjjrjjrSorry, I have no idea! There should be a lot of resources on the web.

[@dougrowell7817]

Geez it doesn't look small to me! I'm looking at a hobby lathe.

[@utubetommy]

@@ydonl I ran engine lathes for years at G.E. Burlington, making parts for Gatling guns. Engine lathes we're classified by size... LES (Lathe, Engine, Small), LEM (Medium), LEL (Large) and LEX (Extra Large). The Monarch in the video I commented on was classified as LES, hence my comment. That said, I've operated smaller lathes, but if you want a machine tool that has any usefulness in a home shop, this is the size engine lathe I would opt for. I've done numerous things with lathes this size, and as I said it's usefulness is only limited by your imagination.

"there is no industry standard so you will find, no consistency" I lost it.. hahaha!! he's doing such a good job explaining things in a professional manner and I feel like right then he really wanted to swear. Great Job!

[@warywolfen]

When reintroducing the tap, I suggest doing it with your fingers at first. Don't attach the handle until you're a good way in.

[@crazymanmichael8386]

i am only an absolute beginner metal mover but i also noticed that he didn:t use a thread gauge and a scratch pass to cross check that the threading operation was set up correctly to produce the desired tpi.

[@charlesseitz1659]

Ya, these videos area great but I have noticed a few very important topics missed. I just saw him check the diameter of the part with a caliper for instance. That is crazy imo. Also, as a modern day manual machinist, the idea of constantly playing with the angle of the compound or tool holder just seems like way more work. Also, they never mentioned setting zeros on the machine and how to gently creep up on a desired dimension. Which to me seems like one of the most important things.

[@armstronglaborde]

@@charlesseitz1659 Notice that someone said that the teaching this video and others on the same topic is a great difference. I enterpret that as superior. However I believe that he didn't want to go into more detail in this video and may choose so in another video on cutting threads. Anyway their are many great videos on cutting threads on a lathe out there. His advantage is his use of his technical vocabulary.

[@Fenderak]

- How much cutting fluid should I use? - Yes.

27:20 you didn't spin the machine to check for obstructions -----I hope your proud of yourself !!! lol

Wouldn’t moving the stock after drilling the centre risk the stock not being clamped in the exact same spot and potentially cause a taper to be turned? Unless you were to use a 4 jaw and indicate it first…

[@Imco1201]

What about indicating the in?

So, Monarch EE Lathe. Ya, Been there done that. but, overall, not bad for internet stuff.

[@MaineMachinist]

One of the big drawbacks of this video is how he uses only commercially produced tools. The average hobby machinist may not have the finances to purchase the amount of tool holders and carbide tools shown in this video. Its better to train people to grind their own HSS tools instead of showing the commercially available inserts. A real Machinist can - and most often does - grind his own tools.

[@armstronglaborde]

Remember that these demos are taking place in an MIT prototype development shop for robotics etc; so he would use commercially produced tools. He did however showed us alternative methods to do things especially in the earlier videos. We would have to focus on the principles and be creative with our improvisions.

[@dougrowell7817]

To be fair, what else can he do? The videos sure look to be aimed at beginners, but not necessarily hobbyists. Buy as you go. Erik is talking from MIT o be fair. He shows the real McCoy but you can improvise I guess. The lathe is certainly not a hobby lathe. :)

[@imranarif1164]

threading shouldn't look like that at all.

[@nakternal]

Making threads with that machine is more difficult than programming in assembly language.

[@miguelcastaneda7236]

we old guys used to use point to point..binary to program now thats hard ...for you guys and 36t fanucs..with everthing in there

[@MrBloodred12]

That seemed to be a harder way to tap then I’m used too

[@berockization]

The knurling info is total crap.

[@Satchmoeddie]

b-rock Why? That screwed up knurling looks just like those high end tools I get directly from China on eBay. ;-) All he needs is more loose chips, sharp edges, and some nasty dirty oily residue, and his work could be worthy of gracing the shelves any Harbor Freight store in America.
