7/8" Pitch Bands11/6
We have always run 1 1/4" x 1" pitch blades (for perhaps 15 years). Last batch of blades through a Morse distributor gave us some trouble, several broke on the weld, some broke clean on the weld after the first resharp, and some were cracked on the weld before the first resharp, and they wont warranty a weld break after a resharpening. Never had this trouble before (same supplier) but... The issue got me looking around at other blade options and Im seeing some really aggressive pricing on 7/8" pitch blades from a few sources. Some are 7-8 dollars per band (or more) less than we are paying. We are sawing all green hardwoods (poplar on up, appalachian region) and are in the low HP range (20). Im thinking of switching. Only issue is we have a full profile sharpener (full grind on the rake, hook, and gullet) that was a chore to setup (supposed to be "automatic" but in many years of use have JUST gotten it to a point where we can leave it unattended through a full band).
I feel like my fighting with the sharpener to this point I know it well enough to get it quickly dialed in to a different blade geometry but wondering if anyone has any input on the drop to 7/8"?
Will the closer tooth spacing cut nails and barbed wire better? (har har har.. that was a joke of course)
Any input is greatly appreciated.
Mark, from my usage and reading I thought most were 7/8 spacing.....kinda sorta...
...actually most lower HP sawmills run the 7/8" spacing due to lack of power. as the 1" spacing is a little more aggressive (it can hold more sawdust also). What may be saving you is the poplar being a little softer (that is my opinion NOT by facts)
Thanks Tim. We saw a mix, of course a ton of Ash with the EAB issue, Oaks, Cherry, Hickory, etc. Like I say we've been running the 1" pitch for 15 years or so.
I guess I'll just try a box of 7/8 and not fool with the sharpener until we see how they run. My concern is that with these small mills they are already slow enough and was worried the 7/8 would slow it down more. That would make the 7-8 dollars a blade savings on the 7/8 not so great.
Thanks for the input.
