View Full Version : A good oil for open gear lathes

My lathe is open geared (Sieg C6 / Grizzly G0516 / Hare & Forbes AL-60 ) and you can see it running with a new gear oil CRC TAC2
that I applied 6 weeks ago. Open gears can be a little noisy, this oil has made a big difference to the sound of the gears. You can
see the 'web' that this sticky oil makes in the video below. That's there as soon as I start the lathe and its been on now for 6 weeks.
I'm not sure how long it will stay 'webbing' but that was just a couple of seconds of spray. Incredible stuff!




Here's the video of the 'web' that is created by the spray oil -

looks like what you get when you mix so Lucas Oil Treatment to the gearbox oil which is something like ISO 68 hydrolic oil. I put it in my RF-45 type mill and it did quiet the gear box some.

Looks like the CRC Tac2 is working well. I don't believe it's available here, well at least not by that name. Over here it's called CRC Open Gear Lube. Gotta love those marketing guys.
There are a number of open gear and chain lubricants much like the one show here. The secret to their success is what are called tacifiers that make it sticky and thus less likely to be flung off.
I've tried the Lucas Oil Treatment cocktail that Loosnut mentions also with similar results.

Look after that hand, looks like that could have hurt.

My Jet 1024 gears scream at high speeds. An occasional dribble of straight Lucas oil stabilizer quiets them right up.

Thanks Willy.

The hand was my silly fault trying to hand hold a 4"x4" sheet of thin steel and drill through it. When the inevitable happened and the drill caught, the metal spun around and I copped 12 stitches. Worse thing was there was a bench vice a foot away!

The local NAPA (auto parts store) carries a store-brand open gear lube. (Probably the same CRC stuff, just relabelled.) Works great on my little lathes.

How is this for getting dust, swarf, & miscellaneous crud stuck to it? Regular oil is bad enough, how does this compare?

Mickey I don't get much (really any) swarf in my gear box end. I have covered up most areas where it entered a long time ago.

It does seem it is for sale in the States, the can hasdifferent graphics on it, but there is a large CRC headquarters in the U.S

Jim, maybe a regional thing, but I haven't seen that particular product, here at least.
Perhaps a marketing focus thing but this is what I've seen here (http://www.crcindustries.com/ei/product_detail.aspx?id=03058).

Wily, reading the marketing claims on the can on the link you posted. It does seem like it's the same product as the claims are virtually identical on the Tac2 can.

Willy

That's what I thought too Jim and why I chuckled earlier about those marketing guys. LOL
If they could drop the B.S. then maybe they could drop the price of the product at the same time. Oh well it is what it is.

STP oil treatment will give you that same web. (Scientifically Treated Petroleum).

Just use chainsaw oil if you want something to gather dust and make a grinding paste. The best oil for change gears is nice thin ATF frequently washed off with thinners when it looks dirty. You don't need so much that it sprays off it is a lubricant not a coolant.
If the noise of machinery bothers you take up knitting.

I thought that's what way oil is for.

The lube looks pretty good to me - but I'd check Machinery's Handbook for gear clearance.

I use this oil from Machinery House (Hair and Forbes) in OZ for just about "one size fits all" as a pretty well universal lubrication oil:

I've even thought of using good chain saw oil on exposed gear trains.

In the past I have used clear silicone sealer mixed 50-50 with oil as a lube it quietens the open gears and doesn't set and sticks to the gears. Depending on the make of silicone and oil you may have to experiment with the mix ratio.

What is clear silicone sealer?

malbenbut
10-23-2014, 03:20 AM
It comes in tubes for holding glass in frames or filling gaps in it smells of vinegar usually 1 for a 12" tube in the UK, can be applied with a mastic gun. A lot cheaper than spray cans.
Google clear silicone sealer.

Malbenbut: how do You mix silicon-paste that tryes to cure from the moment it leaves the packing with oil? Just stir or?

Just mix together you may have to experiment with ratios. In two years mine hasn't set

JME but I'd never put anything like that on a geartrain, but admittedly my lathe has a ~60 lb cast iron cover over the geartrain so little noise comes through. I just add a drop or two of detergent free 10W to the drip tubes every time I use the machine and make sure I pull the cover every few months to add a few drops of oil to the Reeves drive. Personally, I'd suggest folks are over-oiling their machines if theyre getting a mist flinging off the gears, and I'd be looking into a better cover if the noise is annoying.

Hi Jim!
How does this lubricant behave when at rest, does it drip or run off, or does it stay in place like grease?

Hello Thomas, yes the lubricant stays absolutely put and does not even slump down.....no drips, no flinging off.
