RE: Bandsaw Blades4/11
For a 30” bandwheel on a bandmill, what is better to run, a 1 1/2” or 2” width blade with a custom built mill, that has an 87 hp diesel engine. This blade is cutting on average 24” to 30” diameter logs of Northeast hardwoods (primarily red oaks).
What would the optimal tooth pitch be?
Also, what optimal tooth spacing would be needed?
And would you use carbon steel or bi-metal blades?
With that much hp and 30'' wheels I would have to say 2'' band. Bigger band should mean more board feet per day.
That's some serious power on that mill! As much as blade width, look at the thickness. You might want to run .055" thick blades, especially with that size band wheel. I would run 7 degree hook angle with .020 set to start out. Tooth spacing (pitch) at least 1", 1-1/4", if you can get it, because those wide cuts will be pulling a lot of sawdust.
Your limiting factor will be the gullets filling with sawdust from the wide cuts and high feed rates. When that happens, it won't cut straight, no matter what blade you use.
Steel blades. Bi-metal will chew through nails, but they're more expensive & in my experience, don't cut as smoothly.
