Bandsaw deep cutting issues.

[Woodworks]

Don't know whether here or the milling forum would be best for this but I need a bit of help.

 

I do quite a bit of re sawing on my vertical bandsaw. When I say deep cuts I mean up to 10"-11" max. The problem I get sometimes is the blade develops what I would call an oscillation leaving a coarse herring bone type pattern on the sawn face. This can happen with a brand new blade so I don't think it is down to sharpness. I have never really understood the cause and have tried different tensions and blade types but never really seen a clear correlation. What do you recon?

Personally I find it unavoidable on deep cuts. But 10" maxes my saw out. It was suggested to me to cut slower but only improves things a little.

The guy at tuffsaws ( Ian I believe) is very helpful with all things bsndsaw, and it May be worth talking to him. He sells a super tuff fastcut blade, which is ace, cutting very clean thin kerf on seasoned wood. Recommended for veneer etc. I can't recommend his blades and service enough, all superb.

I feel your issues can only be blade related.

Those blades sound perfect. I used to get some nice thin kerf ones good ones from Truecut but they gave up. I have just put a new blade on and had an absolute nightmare in some beautiful walnut which I have just made a pigs ear of. I have been on the phone to the supplier as this blade is worse than the old one I just took off.

Thanks for the recommendation.

 

I've been having some supply issues with bands for my Ripsaw mill, which is essentially a chainsaw-driven, horizontally-mounted bandsaw. The quality has been poor and I've had re-weld everything. It was very encouraging that Ian's website guarantees to re-weld any band which fails at the weld (I'd say 90%+ of the ones I have bought fail there, but when I re-weld them they don't).

 

Had a very useful conversation with Ian, have ordered some bands and will see how they go.

He certainly is a top guy, I struggle to even see the welds on the blades I've had from him.

A big thanks to you James

 

I have some Tuffsaws blades from Ian and they are a revelation to the ones I have had in recent years. I was doubting my memories of being able to cut veneers on a bandsaw during my training but this is now a doddle with these blades.

 

Thanks again

An issue not mentioned is blade set. Even with new blades the set is often dire. Even just one tooth out of set will cause the lines that you are describing.
