What I like about this discussion is that guys are pointing out the different aspects of the hobby that appeal to them without finding fault with other's preferences. To people who aren't into the saw thing, saws are saws. But when you think about it there are some distinct tangents that you can focus your energy on. Old, new, stock, modded, 100cc muscle saws, 50cc screamers. 70cc work saws. Ugly saws for firewood and collector grade saws that you hate to get dirty. It's a more diversified hobby than would be apparent to those on the outside.
Modding saws is just one of them, and even when doing that, there are variations as to how sophisticated you get and how much time you can allocate to building a saw. I passed on a free lathe a couple years ago, cause I was having fun with the basic mods we were doing and didn't want to go the next step which I figured could double or triple the time involved. But it was also a matter of being happy where I was and not wanting to change it.
I think I get the most fun from the dead saw salvage "junk pile" projects that Walt and I started out with 6-7 years ago and continue to do. Stock at first, but then we began working in some mods. Saws like that Jonny "636" I mentioned earlier. It's not just how much power you can get out of a saw; sometimes it's as simple as how much
work you can get out of a saw. Especially one that's been left for dead.
And I'm also into some of the old stuff that doesn't get much mention on this site, but I suspect there are more guys who share this interest. After my Huskys and Jonnys, I'm into the McCulloch and Homelite American classics. Have about a dozen of each. I've always read a lot of history so saw history is a natural fit for me. As you move back on the timeline to the Jonsered 70E's and Husky L77's, you are going back to an era where the Macs and Homies still outsold Husky and Stihl by a wide margin. At least once a year I like to drag out some of these saws and have a vintage cutting day. Fun to run something different and these saws have a few unique exhaust notes that sound great echoing through the woods. Walt and I are planning a day where we take some of them into the woods and get some of these classic saws on video. Better in my mind to enjoy some old saw experiences than to just tell old saw stories.
