Thanks for "clearing" that up for us Bob.On my mills the line size is around 3/8.
But what is more important than the line is the size of the drip or bar holes which is 3/16 on one mill, 5/32 on another and I think its 1/8 on the small mill.
Max flow rate through an orifice is proportional to the radius to the forth power (r^4) so if you need lots of flow the size of the hole is very important.
Temperature effects on viscosity are typically inverse exponential but it's exponential on the Absolute temperature (Kelvin) not the Fahrenheit scale so the effect is not as great as changes in radius.
I typically run my oiler so I can see a small pool of oil on the bar. This means I usually refill the aux oiler tanks about half as often as the saw oil tanks.
I am now thinking I really want a clear tank for the oil, . . . .
Presumably so you can see the oil level? This is not needed if you use a vertical sighting tube which is very easy to attach using black irrigation pipe fittings.

Irrigation pipe fittings another area I need to look at when I am at the hardware store. However I really don't care for the sight tube option all that much I would rather stick with KISS and avoid the extra connections, points of failure and snag hazards. I am sure it works fine for you guys but dunno just figure a clear container would be less hassle in the long run.
My 8 year old sight tubes are still working, have never leaked and never caught on anything.
Some clear plastics may react to oil and turn opaque over time.
BTW silicone/epoxy may also react with the oil and not seal all that well if that is all you rely on to make the connection. Epoxy also does not like vibe if the container is flexible. A physical connection e.g. threaded connections that screw firmly into or against the container work better,
. . . . I am thinking of just using blocks and railroads ties to make a milling platform to get the log up to a comfortable sloped height, I think I may try to do it right next to a sidehill I have to so I can drag the logs up the hill then just roll them onto the platform that way I don't have to lift them with equipment.
Yup the one end I plan to have lower, but the slope will not be the high point, since then you would have to bend down at the start of the log or cut a trench into the slope to walk in.Good idea. but don't make a level platform, use the natural slope to advantage and mill the logs the down slope. That way you should not have to pus much or at ll
