    Could those of you using conditionning belts please enlighten me as to the preferred belt speed to use for best results?

    I'm using a 3M extra fine belt on CPM154.

    Is there any pitfalls I should consider before I get going and also, how fine a grit do you go to before running the blade on the belt?

    Fast! I like them around 4000 SFM. I am using the Norton Vortex belts in coarse, fine and very fine.

    Keep the heat down. They will get the steel hot. Dunk, wipe with a rag and re-apply to the belt. Light to moderate pressure.

    I use them on the 10" contact wheel and sometimes off the bottom wheel on the flat platen. They make a lot of seam noise, (lump, lump. lump) but they can handle the speed.
