    Default sandvik mitre box

    I recently bought a Sandvik mitre box (called a box but would more correctly be a guide).

    However when I got home I found no instructions (what sort of dimwit would need instructions anyhow.

    The trouble was that on closer examination the vertical saw guide is actualy a couple of degrees from the vertical and I can't for the life of me figure out why.

    Has anyone experience of this type of guide or know why the so called vertical is not?

    G'day Denn,
    I have one of those, although it appears from your pic that it is made of plastic - is it? Mine is alloy and I bought it primarily because I couldn't cut a square cut to save me life! I only used it to cut framing studs and noggins so I guess that a couple of degrees wouldn't be a problem. It is designed to be used with a crosscut or panel saw, just holding it against the timber with one hand while you saw with the other. I haven't used it for years because I can afford to expend those little electrons as well as being inherently lazy.
    Cheers
    Graeme

    Oops, why isn't it vertical? On mine, the angle is locked by a pin on the swivel locating in a hole in the base. If there is stuff in the hole preventing a full seating, then the blade guide will not be square.

    Yes Graeme,

    I reckon that mine is exactly the same as yours, I like to use hand tools occasionally because I have more control over the result.

    Okay I am presuming that they are the same. Now I can guarentee that the swivels are seated correctly.
    If you set the guide at any angle (use 90degrees for the sake of the exersise) and then set a trysquare against the upright, is the upright vertical or not? Mine is a couple of degrees out of vertical.

    The pic was a lazy mans effort (I pulled it from the Sandvic site) and is not great so if you wish I will take a better pic tomorrow that shows my point - it's too late for me tonight.

    G'day Denn,

    This is probably way off the mark but there is a school of thought which under cuts miters so that the top surface will always close up fully making it look better and also easier to adjust an ill fitting joint. I don't have one of these jigs so this is a guess re your problem.

    You also mention that it doesn't match your square - not trying to be funny but have you checked the square - many in the shops are not exact but require tuning before use. If you are unsure of how to check - mark a line on a piece of timber which allows you to scribe a line as long as your square, flip the square along the same edge face and check the line - the line and the square should be the same.

    Hope it helps.

    Regards,
    Bob

    Thanks Bob, your first suggestion did enter my mind but not for long - the amount that it is off vertical is possibly 2+ degrees - much more than could be pulled by a clamp. That also answers your second idea - at that amount it is visibly off vertical evan without a square, the square just verifies the fact.

    I'm off to the shed to take a picture of it.

    See what you mean - that to me would appear to be a complete waste of time.

    You say it was bought recently, So I guess you have a couple of options,

    Email your pix and text to Sandvik and ask for an explanation as well as instructions which were missing which could possibly outline some adjustment or tuning - would be interesting to hear their reply as Sandvik used to have a good rep - not sure if it still is today.

    Return to place of purchase for replacement or refund as it does appear to be faulty.

    Last option - bin it and chalk it down to experience - neither satisfactory nor solving your problem.

    Regards,
    Bob

    I think that if I don't get anywhere on the forum, I shall write to sandvik (now Bacho) because I don't believe it is a fault, after all the thing is cast alloy so once the mould is set all the castings are identical. I rather think that it is a deliberate offset for some reason or other.

    As you say Sandvic are/were good tools, I have some of thier chisels and am more than happy with them.

    Thanks for your suggestions
