Does anyone know when the Mac's and Pro Mac's started production? Some use similar numbers and in searching for parts I am unsure if some of the bars, spurs and sprokets are interchangable? The new McCollochs after the brand name was sold use different bars, pitch and gauge. Completely different saws. Second question is anyone know of sprokets or spurs 3/8 inch pitch .050 gauge and bars that fit these old McCollogh chainsaws?
I was tryig to lower the gauge to .050 with 3/8 pitch. and increase the sprokets size to 8 or 9 to speed up the chain and increase the speed of milling. I have a McColloch 650, 1-40, and a 1-52. They all use 7 pin sockets .063 guage and, .404 pitch. I use the 1-40 for some chainsaw milling with the small Alaskan Mill with a 20 inch bar. Slow going due to higher torque with lower RPM's. The other two I had different plans for, but never found the bars and parts for it. Pulled them out again. The 650 and the 1-52 are 89 CC's and 87 CC's.
I would just opt for some new saws, but the cost is high and I plan to go with Bandsaw milling instead. I had a good amount of stored exotic hardwoods taking up 75 percent of my backyard. I want to just have the ability to continue to take in logs and mill as I go every now and then.
