They seem to run in spurts for me also. I still am on the lookout for a 6900 and a 7700. I don’t think I’ve ever seen either one in person.I'm not sure what has happened with the big saws. For years I have found one here and there and long time between them. About 9 months ago i found a 8500 that was nice and never had anything done to it, i have not even cleaned it. So when I turned 77 last June i had the crazy idea to want a 7700. Seems like the saws just started to find me. This is what has found me. 2 8500 makes 3 a 8510 in a box of parts, a 6900 ,5400, 4900 and my 7700. I have enough parts to make another 8500 but would have to get a decal set for it. I'm not looking for anything else but a wood permit mid June.
What does a wood permit allow you to do?
