In sawmill equipment, babbit boxes (bearing housings) require proper clearance between the mandrel and babbit shells to allow smooth rotation; when the equipment warms up during operation, thermal expansion can increase this clearance, potentially affecting performance, so operators should monitor and adjust tension accordingly to maintain optimal cutting efficiency.

All right, I'm just showing you the feed works over here. We put a little tension in our chain, played with the alignment. All that holds the motor down is some big carriage bolts sandwiched through like that. So, we just loosen her off, slide her on that big wooden beam.
Bob's your uncle or maybe John. All right, welcome back to the sawmill. It's Sunday morning.
It's what about 9:30ish.
It's nice and cool and overcast.
>> 10:30ish.
>> 10:30.
>> 10:40.
>> 10:40. Thank you, sir.
>> I hear 50.
>> We spent a bunch of time cleaning up the husk, dealing with the sawdust, getting things clean, so maybe we don't get a face full of sawdust the whole time we're sawing. And uh everything's been lubed up. We've got a big black locust yard tree that's scanned up clean. And I want to make some of these stakes for myself. Multi-purpose stakes out of locust that will last a really long time. So, we're just going to do that.
Inch and a half by inch and a half.
We'll stack and whack and we'll see how it goes.

All right, you guys saw it hopping, >> so the proof will be in the pudding if it doesn't hop. But David got a bar under the mandrel and there was a whisker whisker too much clearance in the babbbit. We could move the mandrel relative to the babbot shells. So I took just a little bit of more tension on the shim pack.
Um, I don't know. Would would that situation because it's warm now and we were good in the winter. Would is that the way it goes? Cuz I get dyslexic about things. Should we have to tighten up the clearance? Now, >> David's saying he doesn't know.
>> Well, if it got warmer, it gets bigger.
The clearance gets bigger. But I don't think that's significant in our our application.
>> We'll make like a cut or two, then we'll shut down again. We'll check heat. But what I want to show you is that the saw The saw spins freely and coasts. So, I haven't increased my babbit tension to the point of uh >> right.
>> Yeah. Slowing it down.
>> Okay. Um I'm not going to I'm not going to sharpen it because that would be changing another factor.
So, we'll try it. It It's It's fairly sharp.
It should cut that. Okay. This log is still pretty wet. See that?
