Hello Everyone,
I am currently working on a 10" Chopper made from 3V. I took the edge down to 0.040" and hand finished to 400 grit, befroe sending it to Brad at Peter's Heat Treating. The blade was HT to a RC60. I shapened the edge and did some testing, after chopping thru 6 or 7 2x6's and about 15 nail, the edge still looked perfect. Impressive stuff!!
The problem is I wanted to finish this blade with a 600 grit hand rub. I started at 220 and got no where. I then when thru x100, x65, x45, and x16 Norax belts at full speed on my grinder. Back to the 220 hand rub and I am working like a dog to get a straight scratch pattern.
Anyone else try to hand rub this stuff? What were your results? How did you finish?
Thank you,
James
