my 404 presets showed up today so I'm making some headway on my 404 vs 3/8 project... will be using the 661 as the test saw
28" tsumura with a 404 tip
3 types of chains - Stihl 404 RS, 2 experimental chains..
middle chain - take a Stihl 404 RS, break it at every 5th DL alternating between cutter and tie strap taken out. Then put it back together so it's a half skip. Probably have 4hrs and 2 bags of presets into it. I need help I know. lol
bottom chain - take a Stihl 404 RS, grind off every 3rd cutter - you basically get 2 cutters (Left and Right) followed by two open Drive lengths. I call it a Double Skip. heh
I also made the same 3 chains in 3/8ths ...well i'm working on the half skip. i need more presets.
close up of the half skip
close up of the double skip - nice grind job. Special thanks to Big T Double
3/8ths vs 404 404 is huge but I'm betting the 661 has the balls!
