Oh it's so nice to see a new mill (I can see Jack drooling allover himself)... I see shes cutting wavy... when I first started out that was a constant battle for me. Couple of things helped me over come the wavy cutting issue:
1) Add a little regular Joy dish washing soap to your water lube - Joy is some slick stuff...
2) Run the blade tensioner a little tighter than what WM recommends. With the blade guide all the way open "pluck" the blade it should sound close to a musical C note. Watch the gauge and tighten when it loosens up.
3) Slow the forward head speed down, the blade should sing a song as it cuts through the log and there should only be a slight drain on the motor in other words keep the motor RPM up there and don't try and run the head through the log too fast. Increase the forward speed a little bit as the boards get narrower, slow the speed down the more wider the boards are. Keep the blade singing... If you hear a "swish, swish sound" change the blade.
4) When you change species change the blade. Don't expect to cut a hickory log, then a maple, and expect anything decent from the maple. Cut all the same species then switch the blade when you start a new species.
5) Always saw clean logs, mud, rocks and debris will dull a blade in a hearbeat. Not to mention what a nail will do... When in doubt hose off the logs or peel the bark and use a metal detector before you place it on the sawmill.
6) WM may not like me for saying this (but I never really cared much what people think anyways) For
hardwood use
Monkfors blades or
Lenox Woodmaster C blades. Buy them from Coleman Sawmill Supply in Orleans, IN, phone 812-865-4001. Coleman Sawmill Supply has great customer service and good prices.
7) For
softwood (Pine/Poplar/Cedar...) use WM 10 degree blades.
8) Adjust the drive belt tension - oddly a loose drive belt will make a wavy cut.
9) when all else fails change the blade.
Running the sawmill was about 1/4 of the work for me, socializing, logging, stacking and stickering, repairs/maintance, delivering and bookkeeping made up the rest.
I really prefer quarter sawing over flat or book match sawing. Quatersawn lumber is generally a better quality product and preferred by most woodworkers.
