There are a lot of factors that can cause saw chatter. The type of wood, your sawing technique, and the condition of the teeth are chief among them, in my opinion. Is your saw new or old? You said you filed the teeth to a rip pattern, are you cutting with or across the grain?
If you have a new saw, sometimes the saw arrives over-set (too much lateral offset between the teeth). The Spear & Jackson saws Paul recommends are notorious for being over-set at the factory. Paul has videos on relaxing the set of the teeth. If your saw is old, it’s also possible that some of the teeth are taller than others, which could cause chatter. A couple passes with a file on the top of the teeth will solve that problem. If you are forcing or “muscling” the saw through the cut, that can cause chatter as well.
Attack the problem systematically. Make one adjustment and test it out before you make another. Eventually you’ll figure it out. Good luck!
In his post, Paul also recommend
– removing the anti-rust varnish (for a new saw);
– lubricating the plate.
– don’t force, let the saw do the work;
– keep in line, otherwise the plate might rub in the kerf which might excite the vibration;
– change( lower?) your speed (stroke/min).
A new saw with teeth spacing precisely made by a machine might enter in vibration more easily then a hand sharpened one (minute variations in the teeth geometry).
Anyway, Paul shows in one of his post that even a new saw benefit from a two minutes sharpening.
Hello every body.
The saw is a old sandvik with plywood handle, originaly was also a rip saw. I filed the top of the teeth to be sure that all are at the same level and after 2 strokes in each teeth. I made like Larry recomend me. I reseted the saw again whith the set plier (nº8) then I relax the set with to hammers.
Now the vibration is less so I think that know is some thing with my technique.
Thanks for your help.
