Parkland College Lathes - The Sheldon Lathe

This is a video aimed at my machining students at Parkland College showing the features and controls on the lathes we have in the shop.

Thanks for taking the time to do this video. This is a great resource for us beginners. Great Job.

AWESOME .... THANK YOU FOR TAKING THE TIME TO DO THIS VIDEO . I have a Sheldon and no-one is around to help me figure it out . I have a job for it already to recut some threads on a Hydraulic gland tractor part . I think I might be able to figure it out now . Thank you so very much .

[@StuartdeHaro]

I'm glad it helped you out. Let me know if you have any other questions on it. Thanks for watching!

Thanks. I have an older model Sheldon, probably mid 40's, some things are different, but I now have some idea what they are for. I started threading, the other day. I'm practicing on copper tubing. Its soft, so I can't screw too much up. I watched another video, on cutting threads, with the carriage moving away from the headstock. I'm not as nervous about running that direction.

bought an old Sheldon off ebay, and this video was very helpful. Plus, I am trying to mentally compare these to South Bend. Seems like these are a little more solidly-made. Exxxxeeeelllllleeeennnnttttt!!!!!

@Stuart de Haro thanks for the videos. How about a maintenance/oiling series? I have a similar Sheldon. I'm sure your students would love it ;)

[@StuartdeHaro]

Thanks, Rasheed. I'll see if I can get something shot in the Fall when school starts back up.

I can't thank you enough for this video, its helped me tremendously with understanding my Sheldon lathe. Speaking of which, I have just purchased a 10x30 UXL-56-P and I want to make sure everything is properly oiled and lubricated before I start playing with it. How do you recommend going about oiling and lubricating prior to use? Went through quite a few forums and one Practical Machinist post stated the best oils and lubrication's to use with these older lathes so per the post I picked up a 1 gallon jug of Mobile DTE-26 hydraulic oil for the gear assemblies and a 1 gallon jug of Mobile Vactra No.2 way oil for the ways.

[@StuartdeHaro]

That all sounds good to me. Don't overfill it with oil or you'll end up with a bunch of oil on the floor. Most of these machines have a small oil sump that has a simple mechanical pump (like an oil can) or just a slinger to get the oil towards the top. The belt drive ones are even simpler. You just need the oil to the level of the bottom of the bearing. Any more and it will just leak out.

This was really helpful. I have a Sheldon lathe and wasn't sure how to use it, so thanks!

[@Heirieh61672]

Ditto, thanks for the help

When you change the belt from high to low (about 2 min mark), you know you can just use the lever that lets you change the other four speeds to make that a lot easier, right? No fighting with the belt, no need to rock or hand turn the pulley.

[@StuartdeHaro]

Actually, I checked on that and you can't. That lever moves the motor and jackshaft pulleys as a unit. That's why the one pulley is flat instead of v-shaped.

What model Sheldon lathe is this? When I got my Sheldon EM-56-P, the half-nut was not engaged with the leadscrew; it was rotated away. Is there a reason for this? Can the half nut ride on the leadscrew when it is not being used? Thanks

[@StuartdeHaro]

I'm not sure of the model and I'm not teaching this semester so I can't check. The half nut should be disengaged unless you are actively threading. If it is engaged, the carriage will start feeding as soon as the machine is turned on. You also can't freely move the carriage when the half nut is engaged. There is supposed to be an interlock in the apron as well that prevents you from engaging the half nuts and the power feed at the same time, so if you cannot engage the half nuts, you need to find which lever switches between threading and feed mode. Thanks for watching!

[@howardtoob]

Any idea what the spindle taper size is? Thanks

[@StuartdeHaro]

I've never had the chuck off of that lathe, but from the size of it, I'd be surprised if it was bigger than a Morse 4. I'll try to check tomorrow night.
