    Plane chatter

    My #4 plane (copy of a Stanley) is working pretty well, but I get a bit of chatter in some spots. Am I correct in thinking that moving the frog forward to narrow the throat will help?
    Cheers,

    Are you waxing the sole?

    give it a try. you may not have enough of the blade supported. try shallower cuts as well. do you notice any difference in the grain where the chatter occurs? That can also be a factor.

    Also try adjusting the chip breaker closer to the edge.. There was a pretty enlightening thread a day or so ago on SMC in the neatherthal haven about that - "Influence of the Cap-iron on Hand Plane" search google shows the video.

    Thanks! I'll give it all a try. The cap iron is less than 1/16 from the edge of the blade, but I haven't waxed the sole lately.

    Roger,
    You didn't say what wood the plane is chattering on, or what type of grain. Figured woods, or very hard ones often cause chatter. Among the domestic woods, figured maples (birdseye curl, quilting) are among the worst.

    Most of what you've been told already is good advice, although I've never felt that waxing the sole reduces chatter. It does make the plane easier to push, though.

    1. take very light cuts.
    2. if the wood has figure in it, or 'reversed' grain patterning, then try planig from different directions.
    3. try wetting the wood slightly - just a light spritz, or a wipe with a wet rag.
    4. keep the plane's mouth as tight as possible.
    5. keep the chipbreaker about 1/64" (~0.3mm) from the blades edge
    6. sharpen often.
    7. Since you don't have a high angle frog for your plane, try putting a 3~5 back bevel on the blade. This, in effect, will give you a higher planing angle which iften helps in hard or figured woods.

    Roger have you ever tuned up your #4. If so did you check that the chipbreaker part of the cap iron is making contact with the blade across the full length of its contact area. Also how tight do you have the lever cap screw that enables the lever cap to exert clamping force on the whole blade cap iron etc. If its not securly held and you come across testy wood that too will cause the chatter.
    cheers
