Blade Speed.
« on: March 10, 2021, 01:39:25 PM »
I've been doing some reading and research before I try and build my own smaller, home owner level sawmill.  I've read that people say 4500 feet per second as a minimum. 

But as I've looked at the commercially available mills, those speeds seem too fast.  Most of the homeowner Hudson models have a 4" clutch to a 16" bandwheel.  Others go to a 16" driven pulley and then 19 Bandwheel.  Woodmizer LT15, Timberking 1220, Woodland Mills, they all seem to have that sort of ratio.  With a gas motor with a max 3600 RPM I'm only coming up with 3700-4475 fps even at the max rpm of 3600

Is your machine home made?  What HP motor and what's your width of cut?

Mine's just under 4" driven pulley to 19" wheels and "cuts good" too.  Homemade from a kit.  Max width is something a little more than 2 feet I think.  It's been awhile and now I've forgotten all the particulars.
