Use the same idea to build something like it.
I take tension off my blade every time I quit cutting for the day and retention it again next time I fire it up to work. Haven't had a blade crack yet. Not sure those things are connected...I'm feeling way behind in the game here LOL.
Oh well, someone has to be the amateur I guess.
Saw some pretty sparkling coming from a blade guide today.
Turns out my blade was trying to cut a bearing in half. I saw a few tiny sparks yesterday but figured it must have been something on the wood.
I just happened to have a replacement bearing in the car from when I originally was getting this sawmill ready to use. Easy replacement.

Cutting my fourth 6x6" the blade started to wobble. Turns out I cracked another blade. That's how the original went. Cracked badly.

Am I doing something wrong? The blade is tensioned by feel because I don't have a spec for it, but it's as tight as I dare put it. Almost no movement when pressing up and down on a length of it.
I take more slab cuts than I need to so as not to push the mill hard (because it's old). Ok, part of the smaller slab cuts might be because I don't want to push ME too hard. I'm old too
Except for one large tree I split in half I think the thickest slab I've cut is 2".
I don't set the blade guide width to each log diameter. I kind of used a general average. Am I leaving the blade guides too far apart? I closed it in after putting a new blade on.
Do I need to be re-tensioning the blade every day? I did notice the first replacement blade I put on (which cracked today) was starting to move back a bit on the guide bearings as it got dull and less efficient at cutting. Today I set the guide so the horizontal bearing is a sheet of paper away from the blade. It wasn't much more before, just enough the blade had to move back a little to touch that bearing.
Or is it normal for blades to break often? I see they get dull quickly, but cracking??
I was trying to estimate how many cuts I made with this first replacement blade. I am averaging 3 cuts per side per beam. That's 12 cuts per beam x 30 or so beams. Is that the life expectancy of a blade?
Hoping for some opinions.
Thanks for sharing the article Mr. Gordon.
What a great example of how one's interests can transform into something with meaning Mr. John_Mc.
Enthusiasm can be a potent catalyst.
I also did that for years, then my friend who has the same model mill as mine, said he never does, and he's had his mill for many years too.I take tension off my blade every time I quit cutting for the day and retention it again next time I fire it up to work.
