Re: OT: Building in isolated location

You got to be happy Bill....almost just about practically nearly in there now!
I look forward to seeing the new improved super-duty Garage Mahal when you get your toys moved in.

Re: Hydraulic/Hydrostatic Oil/Fluids?

I would avoid ATF's like the plague. In a application that is designed around a particular ATF....yup....use it, but other uses, take care. Extreme care. There are, and can be problems with coefficients of friction,ie; type F's vs Dexron, and seal compatibility. ie; Dexron & Dex/Merc with Viton seal...

Re: Hydraulic/Hydrostatic Oil/Fluids?

They also object to zinc and sulfur. The 'Z', in ZDDP is zinc, (zinc dithiophosphate....if I spelled that right) but I their primary whine if I remember, was the 'P' phosphate part. Sulfur, and lead.....are known enemies of the EPA Gods. The old SCL type EP gear oils got on the hit list years ago. ...

Re: Hydraulic/Hydrostatic Oil/Fluids?

The only AW additive in motor oils I remember the EPA going after, was ZDDP. I think it was mostly due to the phosphorus in it, as it damaged catalytic converters. I think it happened sometime in the 90's. Many motor oils still have it, but only in some API codes, and they cut down the amount used t...

Re: Hydraulic/Hydrostatic Oil/Fluids?

FYI....it also works better than ATF', C3 types, AW's, and TDH's in power-shift transmissions.

Re: Hydraulic/Hydrostatic Oil/Fluids?

Many of the additives in motor oil are there to deal with products of combustion and so are useless in hydraulic systems. Many useful additives cannot be used in motor oil due to EPA regulations that do not apply to hydraulic oil. Motor oils are also optimized for high temperature operation and low...

Re: Hydraulic/Hydrostatic Oil/Fluids?

Oils with more anti-wear additives are better.
Motor oils have more anti-wear components than AW hydraulic oils, and tractor hydraulic fluids.
Because of the increased life motor oils provide, that's what I have used for many years.

Re: Cutting plastic

Edit.....

I have used hole saws. Kind of rough, but easy enough to clean up on the lathe if necessary.
Annular cutters work a lot better.
Keep it slow, and melting is not a problem.
I have made many thicker discs for linear bearings, using round-stock, and parting. Slower, but prettier.

Re: 8hp vs 16 hp

Not in the weeds....just equipment nomenclature..... Hydraulic drive refers to fixed displacement systems, ie, generally; gear or vane pumps & motors Hydrostatic drive refers to variable displacement systems, ie; piston pumps using either fixed or variable displacement motors Torque converter, is a ...

Re: feeling stupid

Earlgo, I use mine in for work in my vise, which is where I cross drill about all of the pins I make. I dial in the vise, toss the first pin in it, and let it overhang, and use a end stop, and find center. Need the overhang to drill through anyway. For some short pins, I let it hang over to zero to ...
