water lubrication
« on: February 08, 2020, 01:21:30 PM »
I have a Woodmizer LT 28. I'm having trouble regulating the lube water. It seems as though I get a pretty good stream of water then back it off the slightest bit, the water stops.  Should I try a different type of valve?

Blow out the valve and line with air hose sometimes just funk in the line and valve.

The valve on the tank on my LT 35 was plastic.  I replaced it with a brass hose bib. It works way better and has finer adjustment.

I had the same problem with my LT 27. I use a gas pilot swing valve in the feed line closer to me. I use that to regulate on and off once the main valve is set. This has worked well for me. Getting the plastic valve flow just right is a problem sometimes.

  Did you crack/open the air vent on top? If it gets stopped up it will prevent proper water flow too. Just a thought.

An idea I had for this was to install a small low current draw water pump in line before the valve so there was always pressure against the valve and wouldn't plug as easily. Just a few pounds would do I'd think (5-10). That way if it did plug, just a quick blip of the valve would clear it and flow would still be regulated with the valve as usual.

Another advantage would the constant pressure. As the water level in the tank goes down so does the pressure(head) in the system. A little pump may solve that problem.

One of my mills is the older (1990) WM Lt40 HD. It has the gravity feed water lube tank located on the top of one of the masts. Works well but when I raised it an additional 10" up in height, water pressure also increased, big plus.

On my lt35 I added another valve beyond the first one. I then use that one to regulate the flow, and use the first one to turn the lube on and off thus not changing the flow amount.

There are many ways to vary the flow; windshield washer pump and a hazard flasher.  smiley_headscratch  smiley_idea

My vent is open so it is not pulling a vacuum.  I like the idea of using a hose bib type valve.

When we had an lt-28, we opened the plastic tank valve to the proper amount of flow for what we were sawing and had another brass valve in line that we would open at the beginning of the cut and close at the end.  Occasionally the screen before the tank valve would need to be cleaned/blown out.  I spent the last 30 minutes looking through my gallery but was unable to find a picture of it.

I added a second valve also that I could reach from the same side of the mill I operate from. Set the top one to flow how you want it and the second one is just an on off.

I think I plumed mine just the opposite!

The valve on the water jug opens the flow, and the one right near the control console adjusts "how much flow"!

I also have a solenoid valve mounted under the platform that the fuel, and the water jug sits on!

It's wired to ground, and to the #2 lug on the feed drum-switch!

Water only flows when the sawhead is going forward, when it stops or backs up, the valve shuts the water off!

It's the same valve that's used in the Wood-Mizer Lube Mizer system!

I don't have any pics!

I mounted the solenoid valve on the underside of the fuel and water platform, and ran a line from the water jug to the valve, then across to the point where the water drips on the blade, then installed a "fine adjustable" valve in the line near the console!

It's a very basic setup, but it really works well!

Sounds like a nice inexpensive solution, thanks.
