I am no expert but it seems to me that the circumference of the piece to be knurled really needs to be some multiple of the repeat pattern of the knurling wheel otherwise it is inevitable that ghost repeats of the pattern will be developed. There is no way to get the first pass around the rod to create a deep enough impression to force the knurl to follow it second time around. I have not seen any knurl lessons say this but it seems to me to be what happens.
@@Hereford1642 You are correct. The straddle knurling tools do a better job at applying force to form the metal. Sometimes when the two diameters can't mesh correctly, the tool will "cut" material away. When that happens without flood coolant, you typically see a rough looking knurl.

Really nice to se fully formed beautiful knurlings! Most knurlings I see here at youtube looks like shit.Theese looks really good! Well done!
Thank you. The straddle knurling tools are relatively forgiving.
