    Default Combo Plane

    I bought the Veritas combination plane. I was disappointed only in that the blade reaches no further than 3/8 of an inch. Lee Valley keeps telling me I can make it go further. It was suggested I raise the skates but it appears to me one would have to take the plane apart to do so. They have not been able to explain this to me in a way I can understand. Does anyone have more information.

    can you post a photo?

    I don't really understand the limitation of "the blade reaches no further than 3/8 of an inch".
    Typically I'll only have less than 1/32 of an inch of blade exposed on a plow or combination plane.

    Combi planes should plough, bead, rebate, etc. easily 3/4" deep.
    My Stanley No. 45 can probably reach a depth of 1" or more before its stock and handle becomes its final, inmovable, unyielding depth stop.

    When you say 3/8'' do you mean past the skates? As Ian said the blade only has to be just proud of the skate. The skate is for all practical purposes the sole of the plane.

    There is also plenty other info online on how to setup and use a plow plane.

    I do not know what you are wanting to do. When using the Combo ... or any other plough (plow) plane ... the blade needs to be extended by about 1/16" - 1/32" past the skate. Anything more and the blade will dig in.

    I have not measured my blade extension, but it if were "only" 3/8", this will last you a long time (unless you are in the habit of grinding excessively). I hollow grind once, and hone on this. Grind once every few years.

    I thought I should be able to plow or clean a 1/2" groove as an example. But the scate stops the blade from reaching that depth and that's before sharpening it. I don't understand why Lee valley mentioned the number 5/8.

    Have you adjusted the depth stop?

    From the Combination Plane instructions
    The combination plane consists of three main parts: a body, a sliding section and a fence. The body includes the blade bed and depth adjustment, and the tote. The body and the sliding section have depth stops with a capacity of 3/4",

    sussertown,
    I think you are a bit confused as to what the skate does. Imagine it as the sole of the plane so the cutter edge just pokes out past it the depth of a shaving. The skate rides down in the bottom of the groove just like a plane sole on any plane rides against the wood. The depth stop/stops will stop the plane cutting when they reach the top of the groove giving the set depth. The narrower cutters are only used with one skate. Perhaps that was you'r problem. There is a bit of a learning curve getting a plow plane working but when you get it well it feels pretty good. Read through the instructions (even us men have to read them now and then)a few times and watch a few youtube clips on plowing. If you still have problems then post some pics of the setup you were using so we have less guesswork to do.
    Regards
    John

    1/16"? Was that a typo and you meant to say 1/64" - 1/32"?
    (I don't think even The Schwarz could manage a 1/16" depth of cut; and that's Arnold, not Chris!)


    Susertown; have a look at this picture of a Record 044 and a Veritas side by side:

    The red line on the Record indicates the max depth of cut; it is determined by the depth of the skate plus the cutter protrusion. My Record 044 has 5/8", my Stanley 45 has 13/16" and my Lewin 6-15 gives me an almighty 15/16" skate depth.
    The blue line on the Veritas represents the depth of cut set by the depth stop.
    The green circle on the Record represents the cutter protrusion past the skate; around 1/64" to 1/32" (or 0.3 to 0.8mm if you're Imperially challenged!)

    I don't own a Veritas combi or plough; but I would imagine that the blade could probably get around 3/8" past the bottom of the skate; if this is your complaint then I'm afraid you are trying to use the plane incorrectly. As others have pointed out, you only need a small protrusion past the skate. The total blade extension past the skate represents the amount of usable blade available that can be consumed through sharpenings etc. As Derek rightly stated; 3/8" of blade will last you a long time.

    Actually; it is permissable to extend the blade beyond the skates to deepen a groove but only after the tool has reached its maximum depth of cut first, and all the OEM literature that supports this method states that the subsequent finish on the bottom of the groove will get worse the deeper you go. Plus there is a real possibility of snapping the cutter; particularly the thinner ones.
    Nothing succeeds like a budgie without a beak.

    Yeah, 1/64" !!

    1/16" ... Good Grief!

    I re read the instruction manual and found nothing relating to 3/4".

    you sure?

    Page 2, 2nd paragraph
    The body and the sliding section have depth stops with a capacity of 3/4",
    scoring spurs for cross-grain work, and bevelled skates to permit the use
    of beading, reeding and fluting blades.

    But the question remains.
    How far are you extending the blade below the bottom of the skate? 1/64 to 1/32 of an inch or much much further.
