Hi, Dean.
I bought a Jred 670 parts saw from you via eBay auction. Smooth transaction. We communicated on (self-edit, you know, the other site).
I have some (dumb?) questions. Before I ask them, I want everyone to understand that I AM NOT trying to start a saw builder pizzing match. That is the last thing that I want. And I AM NOT questioning Dean's work; I'm simply curious. Maybe the numerous Saw Wars soap operas here did affect me after all. If you decide that this is a potential can of worms, & don't want to respond, I understand 100%.
That said, what sort of gain can be expected from the modest modifications that you mentioned? I realize that we're speaking of woods saws, not race saws. Please understand most of my comments are based on what I've read here & on other sites, not from personal experience. I've also read that a small gain will seem more significant in a smaller saw, less so in a larger saw. I've read that different saws have different requirements, & will produce different outcomes. Can the gains be expressed (generally speaking) in percentages? Such as 15% gain? 20%?
With all of my apologizing & explaining, I hope that my questions make sense.
Chris J.
