My Harisson 140 came today John, can't wait to get it running up in the morning man

Glad to hear your love for your tools. Taking good care will help them to last a long time! When I went from regular 15w-40 to 0w40 syn on my MB diesel I picked up 1mpg american.

Thanks John I just ordered some for my Harrison lathe

John, Thanks for another important video. Your headstock wouldn't last very long without oil in it! I hope Debs is doing fine. I'll comment more after your Sunday Night Nitecap. Thanks again! Have a good one! Dave

That was beautiful inside. You had to be very pleased seeing that. Say HI to Debs!

John, Smart... I would love to revisit this in 3 or 6 months or so (open her back up) and take a look at the oil and gears. Best to Deb! Jim

I wonder how this is 4 years on. I really need to clean my lathe more. Nice vid' keep 'em coming.

I have been watching loads of lathe videos recently. I thought my old Colchester Triumph round head lathe was noisy. After seeing this I have realised I have one that is extremely quiet. Not that yours is noisy at all - just mine is like a ghost!

If I had a lathe that nice, I'd be putting in Royal Purple synthetic racing gearbox oil too. That lathe rocks and I'm jealous.

I put a small magnet in the oil way to the front bearing as I had problems with my gear box on the L6 just to catch and filling's

John, NASCAR gear box oil... Be sure and keep an eye on your lathe... It might start going in an oval and only turning left. All the best... Chuck

Harry likes the new juice. That should make him Happy Happy Happy!

At one pointing did a bit of research into gearbox oils for an old car I had. I discovered that sulfur based gear oils for rear diff's shouldnt be used with bronze, but anything without sulfur is OK. Which includes most ATFs. What atf doesn't do for me is a high enough viscosity for my lathe. Thanks for the video, I think I'm going to do the same with my noisy lathe, get some good modern oil in there. Your description of that top oil channel made me think I better go check the leveling of my lathe to make sure the oil can flow to the front bearing right.

You know that yellow protective foam they put around scafolding in public places. I used a small piece of that over the microphone on my mx20 and it reduced that focus on backgound noise, did not effect the general sound, and also cut down wind noise. Cheers

Top job 👍🏻

Very important to change the oil. That it increases mileage is simple, it has less change in viscosity with temperature rise, so they can make it a lighter weight oil while still having it be a good lubricant at running temperature. The hot oil is as viscous as the regular oil, but when cold it is still the same unlike the regular mineral oil, so it absorbs less energy in the box to churn it, and thus the box runs with less losses. Your car box would be running about 10C cooler after a long drive. Less heat generated by the oil churning in the box is less work done by the engine and thus less fuel used. Impressive that they put in the swarf magnet, and that it is still clean. I have found that they will grow a thin film with time of wear particles, so your lathe looks like it did very little work, and not much high speed operation, which would have generated the highest force on the gear teeth.

Royal Purple? That’s actually some excellent gear oil although I would never imagine it used in machinery. How’s it working? I’ve used Lucas in my bandsaw gearbox and it seems to work decent so far.

Glad to hear that John I have a spare clutch assembly for mine in case parts get scarce cheers but I don't have the brake items

Did you make a new work light for this lathe?

Hi John. Did you manage to get a quick change tool post for you Harrison 140? If so does it have a manufacturer and model number on it. Regards. Tony

I bet you love your new lathe! Royal Purple is some super good oil! Though not cheap. You are correct: synthetic oil does improve gas mileage! In any car. Not much, but worth it over a few thousand miles. By saving just a few gallons (or liters) of fuel pays for the extra cost of the synthetic oils. It's more stable over temperature ranges than organic oil. It also increases the lifespan of the moving parts. No gimmick, it is true. The only negative issue with synthetic oils is: it's expensive and it finds any small crack or pore to leak out of (because it is so "thin").

excellent,using a good grade lubricate can save $$$$$$$

Cool John, a racing lathe, or,,,, a lathe to make racing parts with! Spotlessly clean too! ;o] O,,,

Do your chips bounce off of that old door? I have some painful memories of that.

hello John , good videos , you mentioned you had a colchester Bantam which had a noisey ol gearbox , well my tripumph lathe is just the same , get it in high gears an doesnt she go to town !!! keep up doing the videos , all the best ........

sounds nice that john . i dont think ATF would harm bronze bushing they used to use in nearly all rover and quite a few Austin gear boxes from what i can remember i know my SDi run it and it was manual

John I noticed that the chuck takes a while to stop was it like that before you changed the oil ? Or could it be the brake is worn , regards to both of you

I hear royal purple gear oil shears easily and turns into a watery viscosity.

What sort of speed does one use for a wiggler, and for an edge finder. I cannot find a speed that works well with me. The fault might lie in the wiggler or edge finder quality. Norman

Pain all night but its eazzing now

Where do you get the royal purple old mate.

Pozdrawiam z Polski ! -Paweł.

whats that noise 6:54

What do you think of treating gearbox whit www.ceramizer.com/content/view/38/45/ works grate on noisy old cars gearbox makes it less noisy

Anyone know where I can get this product at a reasonable price? Best price I can find is £34.94p per litre including p&p. As much as I love my lathe this does seem a bit steep.

That oil looks thick, we use tellus 68,

Is this available in English?

Well I won't be putting funny oil in my lathe ! It'll be proper oil from a proper oil company - Shell or Esso/Mobil. All oil will lubricate but that's not the real issue. The real issue is compatibility with rubbery compounds as used in oil seals - and using an oil that keeps them supple so they keep working as a seal. Folks like John should know there are about 4 different automatic gearbox oils (Type G (Old Fords) and Dexron II) are the two that come to my mind and I can't think what the real difference is other than caring for oil seals. Apart from viscosity.

Is there a version of this video in english???

I wish this video was in English.

OK love been in pIn all night but its eating now u and alin and kids OK xx

Bugger off, Dude, you must add captioning.
