Resawing - cut results - one face smooth, the other face rought

Post by poihths »

So I'm working on my resawing skills, which are as limited as my resawing experience, i.e., very.

Got a pretty good cut on my first try as far is getting through the board really pretty straight.

On examining the cut, it was really striking that one cut face was quite smooth, the other very rough - as if something was happening on one side of the blade that wasn't happening on the other.

Any hints on what to look for?

Just guessing here, possibly your fence is not aligned or your blade is twisting. That gives one side a smooth cut while the rough side has incomplete contact with the blade. Usually an imbalance like that, or just one side of the blade sharper than the other, results in the bladed traveling off the line but if the wood is forced place by a fence and feather board you might get a straight cut but not with both sides coming out the same.

I’ll always run the stock through my thickness planer after a resaw. I’ve found both sides of the cut need it to bring everything into square and smooth the cut surfaces.

In my past experience with bandsaw blades , if the kerf on one side is not the same your cut will not be true and it will be very tough to keep the cut on the cutline or the blade from binding . moisture content can also effect the cut . most blades will not clean the saw dust from the blade and or want to follow the grain unless the wood is dry . not sure what blade you are running / TPI etc / or the size of the stock you are using but normally you will want the biggest blade you can use . blade tension is another important thing .

Same here. Both sides of my resaw cuts are rough so I need to run them through my thickness planer to make them useful.
If one side of your blade was much different from the other one, the saw wouldn't cut straight. It would pull to one side during cuts.

I just got a new bandsaw (1995 era, but still in original box) and I want to resaw wood and I WANT both sides to be as rough sawn as possible to mimic barn wood. Any recommendations on how to achieve that? Use as coarse of a blade as possible? or any other suggestions?

I want rough sawn look, that you tube video is for weathered or barnwood. But thanks, anyway. I did find a YouTube video that says take an old table saw blade & slighty bend one tooth.

Opposing teeth will make both sides 'rough'.

Copy that , there is a tool that sets the kerf on some blades , hand saws , band saw blades and such , I have never done it , it wouldn't be beyond my experimenting capabilities to find a used one and a old blade for the band saw and gently adjust a couple teeth , my guess is that if you do not do it evenly than the blade will not cut straight. not sure I would try it with a saw blade on a table saw, those things spin rather fast compared to a band saw and balance is quite necessary .JMO https://commonwoodworking.com/sawset-guide/
