Goto your local Auto-Parts store, get some Lucas Oil Treatment, add it to the oil, I use it in the gearbox oil and on the side gears on my Clausing, made the machine WAY way quieter!!! Makes the oil more "Sticky" and it grips and hangs on the gears longer - you wont believe the difference between that and regular oil with no Lucas in it

There's no doubt about it, if you've a problem you fix it. Good Job.

Great build. This would have many applications. Jere

That's a very good idea. And the filter and the magnet makes it even better.

Definitely one of the most clever things i've seen in quite a while

Noisy gears remind me of stories about ol' timey used car dealers putting sawdust in the gearboxes to quiet them down for a 100 miles or so 😆

Your solutions to problems and resultant custom devices are a wonder to behold Winky. I wonder how the oil quietens the rattle down. The heavy weight oil probably means its cushioning the slack between cogs. That probably means that the cogs are relatively loose to reduce friction while sliding past each other. Also perhaps, meshing is deliberately loose to overcome any profile deficiencies to keep gear machining cost down. I know, too much detail and probably wrong, but fun to consider!

Maybe in the future you could build a cam actuator for the pump and eliminate the manual operation. In my opinion, lubrication is always an added benefit to just about any machine. You get two "atta boys".

Mark another excellent project both in design and craftsmanship. Just thinking out loud, it would be interesting to see what kind of noise comparison you would have with something like spindle oil. As the gears mesh together the compression is what creates the noise. With the thicker viscosity oil does the compression increase and noise level increase? Or just the opposite with something like spindle oil. Surly it would be easier to pump. Again, just thinking out loud. Your ideas and execution are always Top Shelf. Thanks for taking your time for all of us here.

As always, your creativity and ingenuity are cool. People like me have less vision. I’d likely would have bought an oil pump or something. Great video, thank you!

Very nicely done!

Works great Mark, Well done. Thanks for sharing.

Always coming up with great ideas... Good one Mark !

I also like it. Nice design. Very well done. Dave.

Great video , very innovative

Great project, Thanks for

Awesome idea, years ago in the machine shop at the mill I worked it, they would use STP for their gear cases in the machine shop.

Nice! Pretty ingenious ingenuity.

Good lubrication,Mark.Thank you.

Very smart thinking thanks.

Pretty nice! Good job👍

Great idea Mark!

I used to have a S.B. Lathe just like yours, My Father bought it in 1960. I'm still kicking myself for getting rid of it!

Interesting bit of engineering going on there. There is another product that I tried that was recommended by another youtuber called Motor Honey that worked pretty good. Thank you for the video.

Thanks for sharing

Now that's one heck of an idea, wish I thought of that. May do something like that to my sb9

Hello Mark, Great build, thanks for sharing... I was thinking maybe a future enhancement would be some sort of cam powered for the motor that moved the pump handle... Take care. Paul,,

Good idea Winky.

Good job Winky, consider a cam setup with a roller to pump the handle whenever the spindle is running. Should make another great video. Cheers!

Great job, beautiful workmanship. only comment I would make, (have many years experience with cantankerous grease guns) I would have tried to have the pump submerged. Good luck and thanks for sharing

Perhaps a good future project would be to get a set of gear cutters suitable for that pitch and cut a new set of gears on the mill with a dividing head.

I like it, no I love it.Great job….

You might try chainsaw chain oil. Similar to STP, but it's typically not as viscous. However, it's typically made with tackifiers that make the oil really cling to the moving parts it's on. Now that I think about it, perhaps you could adapt a chainsaw auto oiler pump to drive from the lathe

Great idea! I think the “air” is due the fact that grease guns typically have a spring that force feeds the pump the grease and the high viscosity of grease doesn’t force the grease past the threads on the barrel. I think you are drawing in air around your barrel thread (at least above the fluid level) essentially losing prime to some extent. You might try your pipe dope between the the barrel threads and your steel slug.

buen trabajo amigo

That's a I need to do that.

That’s a clever design. I wonder if having an electric pump that turns on when you turn on your lathe might be best. Then you don’t have to worry about it and it stays quiet.

I am trying to remember the oil test display that used to be on the counters of auto parts stores. It had a hand crank and 3 gears behind a lexan view port. have you tried that oil?

Great job, chain saw bar oil may be an option, very sticky

I wonder if you could make a foot pedal to pump it so you can pump while you’re machining. Nice job sir.

U need a check valve between pump and mana fold because when it is a grease gun the end of the hose the coupling is the check valve

Did you try thread tape? Air can pass between the 16tpi, without a good seal

Winky, it's a Friday night, uh ...actually early Saturday morning. Lets call it nearly 1 AM. The Twilight Zone will be rapping up and Alfred Hitchcock will be coming on. My daughter lives only 7 miles away but I haven't seen her in months. Sounds depressing? Well, it isn't. I multi-tasked and watched your latest video! Thanks!

Winkey you could have rotated the chuck to test the thread 😮😂😊

I would experiment with hypoid gear oils, say 90 wt. The oil you are using looks a bit thin. Also think about putting a drain plug in the bottom and a magnet. Keep us updated on your progress.

I use engine assembly lube , stays on the gears alot longer.

Does one have to be cautious to make sure that the oil selected is compatible with the plastic used for the gears...????

Great idea? Do you still put some oil on the wheel axles or does it splash enough to take care of that? My clock repair background snuck through. We call gears "wheels."

Was the noise from the metal gears really that bad?

Great job as usual, but I've got ask, why did you put the lever at the back? Are you thinking ahead to when you add a cam to operate it?

Hold the handle and turn the Chuck to thread it on?

The air is getting into your pump by threads of your slug you turned. You should have included an print or thread sealer

If you want total quiet, throw all the gears in the garbage and do a Clough42 Electronic Lead Screw installation. Makes easy one button threading both imperial and metric. Brings your lathe into the 21st century!

🇨🇦🤓🤟

What about mounting the pump lower than the reservoir? This way it will not suck air and will always be primed.

I’ve been using Mac’s open gear lube spray from Napa on my Atlas lathe gear train for years, works great

Hi, what sensor do you put in the Spindle?

Next add a foot pedal linkage so you can just use your foot ???

try power punch, that will give you some good results.

Nice, but that’s why helically toothed gear exist.

Try chainsaw bar oil, it will quit the gears

You could have just cut off the original grease tube and welded a bottom on it to get your reservoir.

Just hand spin the chuck to try it.

Now you can spend " more " time with your Wife ? She can pump the oil as you work ?? Sharing Hobbies is Quality Time !! 🇨🇦🤓🤟

Model engine oiler ratchet type

sounds more like you don't have enough clearance between the gears.
