Using Paraffin On a Bandsaw

I think the use of wax is much cleaner than oil. genius idea. You're a smart person

I have no experience using common wax, but the wax sticks made for the purpose work very well. As I understand it (and as I do), you don't leave it in contact with the blade. I usually start the cut and let the teeth rake through the wax (tube held in my hand) as it starts cutting. This makes a small deposit of the wax on the material just ahead of the cut. As the blade heats up a bit and cuts through the wax buildup, the blade gets at least a few passes through before it's all gone. For common structural materials, that's likely the only application it will get. Longer cuts, every so often it gets another application (if I think about it). As I understand it, the wax (additives?) coats the blade and continues to provide benefits for some period of time.

And it may just be the K&N fallacy, but it seems to cut easier and faster, and the sound seems to be noticeably "smoother"(?) or less "raspy" when the wax is in use.

Does the wax have any adverse effect on the drive and idler wheels?

The sticks I use are intended for that use, and I've seen no problems resulting.

I have used the wax from the grocery store canning section and I have not noticed any adverse effects from it.
(Study of one.)
