Title: Grinding Wheel Moisturization
Post by: RutherfordbHaye5 on August 12, 2018, 01:24:43 PM
I am pretty new to the cab cutting scene and I decided on the lortone combination unit for my first machine. I know that the grinding wheel needs to stay pretty wet, so I got a gravity powered water system. However, the drip system only gets about half the wheel wet at any given time, leading to faster wear on one side of the wheel. Any suggestions on how to fix this?

Water seeks water. One solution to your situation is to take a sponge and as the wheel is spinning use the sponge to make sure the entire surface is wet.  Secondly you are moving a wet stone back and forth across the surface of the wheel and that is carrying water across the stone.  If you are leaving a white or stone residue streak on the wheel, you don't have enough water or you are not moving your work across the entire face of the wheel.  You can attach felt, or plastic scratcho pieces or whatever to the top of the hood to help disperse the water, but its your job to make sure that you are using and "wetting" the entire face of the wheel.  Don't just work where you see water.  I hope this helps.

I kind of like the idea of using felt to disperse the water. Ill give it a try! Thanks!

I never liked drip systems and use 2 squirters in the tray on which ever wheel I am working on.  They are pretty inexpensive and they keep the wheels nice and wet.

I've used drip systems at shows but they don't provide as much water as I think you should have.  A recirculating system either with a small bubbler under the wheel or cascade system with pump will give far more water on the wheel and can allow for warm water as well.

 I use a 5 gallon bucket mounted above and to the side of the machine.An aquarium air hose is used from the bottom of the bucket to the cabber. I drill a hole above the wheel and the tube delivers water through the hole. I hog off rock quickly with a 30 grit sintered wheel and this system provides lot of water to the wheel and the water volume can be easily dialed back by using a valve on the tubing line.
