another thing i just thought of. Seeing that i will use the lumber i mill for building furniture. Im concerned about the bar oil and oil from the aux oiler soaking into the lumber and causing finishing issues
It probably depends on the wood but most all of the oil comes off in the sawdust and you really have to lay it on thick to have finishing problems. If you are finishing mill cut wood with oils or waxes a slight amount of oil won't make much difference anyway. If you are finishing mill cut woods with anything else one might ask why. If you are looking at using polys or epoxies then the wood should probably be at least sanded
This is how much oil I like to see pooling on the bar in dry wood.
The most likely place I get oil on the wood is on the outside of the log like this.
Given the size of the log I probably have the oiler up a bit high to get this much spatter.
By the time the wood has dried most of the oil has evaporated or bound up in the wood in some way so that it does not affect the finish.
