It's easy to forget about the many variations of sawmills/engines and not take into consideration that there is no "one size fits all" regarding many sawing operations.  Since a run a Diesel, I had never thought about a gasoline engine having to "governor up" and adjust itself to the sawing load.  Yes a Diesel also has to adjust, but because of the torque available, this happens almost instantly.  There is no "hunting".  (At least with mine.)

For several years I was experiencing ~6" of ripple at the beginning of many cuts.  I finally realized that this was being caused by my entering slow and speeding up during that 6".  This ripple was eliminated when I began entering the log/cant at or near sawing speed.  If my engine slows down when I enter a log/cant or if the blade moves/jerks the log or cant, it's past time for me to get a dull blade off.

Everyone has pretty much covered this topic,  but having sawed around 100,000 board feet on a 13hp gas manual mill, then upgrading to a high HP diesel hydraulic, I can tell you from my own personal experience that they are worlds apart. But not in a bad way, but in a technical way.

i should have added to the last post that with the s&w 125 30 hp electric you can enter the log as fast as you want it will either saw or lock the belts ;D if you hit it to hard in the bigger logs   but as mm said there are so many mills/engine/motor combinations only experience can tell you whats the best for your setup :)

7 HP gasoline + manual saw + novice here + almost always dead standing stuff = eeeease into that log to see what's going to happen. If that goes well, try faster entry on the next cut.

I can go as fast as I can walk when sawing just a few inches wide at a time. ;D

There's an old dried out white oak around 20 inches waiting for me to figure out how to saw it. Glad to see some experienced sawyers speak on such things.

Find something to do that interests you.

This is a video of the first log that I cut on the LT40 about 2 weeks ago. I forgot to turn on the lube mizer and the blade was smoking  :-\

Good to know...I wish that I came from the factory with grease zerks on my joints.  Will have to drill and tap my own I reckon, preventative maintainence is unsportant

This is how I saw. 16.5" wide white pine. With Turbo 7s I could go faster.

Dave that's impressive. I want wireless. I had trouble viewing my clamp this afternoon sawing a customers cedar mantle and was trying not to damage the live edge surface (the bark). If I had wireless I could see the whole shebang.

The wireless only works on the head not for controling the hydraulics.  But don't worry the whiz kid we all know as Georgia Mountain Man aka Paul will probably figure it out in his sleep one night

 What he said. Generally, i don't mind that i can't run the hydraulics from the remote. If i had help, then i would want to be able to run the hydralics and Accuset from inside a heated and air conditioned vehicle.  ;D
