I like a drip of soapy water on the band

I have a tank on the mill for just that. But this is a fresh poplar log that came with its own cooling and these are just practice boards that I'll cut into stickers later. Once its all set up and running the way I want it, I'll use water and soap to cool and lubricate things a bit
The bigger white tank is for cooling the cut and the little orange 3 gallon one for fuel
