truing an import slr

i've got a 2012 grizzly slr. it appears to be the same as the entry level oliver, cantek, extrema, etc. model. it does a pretty good job of straight lining, but the blade is cutting slightly out of square. i measured the run-out and we're .001" so this isn't it. with the blade over design, i'm guessing there isn't a way to adjust an tilt of the blade or arbor. the only other idea i have would be to see about adjusting (or thoroughly cleaning) the race/chain, in order to make it square to the blade. grizzly isn't any help and there is nothing in the manual about adjusting either the blade or chain. i'm only taking about 1/64" or so on 1.5" - 2" thick hardwoods.

has anyone done something like this? any other thoughts (beside upgrading to a diehl - i tried but it is simply beyond my budget)?

Well, see how the motor or trunnion is mounted. Maybe there is a place where you can insert some shims.

I have very little knowledge of the machine but there must be a way to adjust it. Shimming the blade arbor (trunnion) sounds like a good thing to investigate first. I would be leary of adjusting the guides unless you had reference manual for it.

Perhaps you could buy a Cantek manual? They might be more helpful.

Good luck!

thanks for your replies.

i had the same thought about shimming the arbor housing/mount shortly after i posted this. we're going to explore that later today or tomorrow.

another thing that seems to be happening every now and then - we're getting either snipe (like snipe) about 6" on either end, or the saw is cutting a convex cut (opposite a hollow cut). i don't think this is tension release as the same convex cut has been on either side of the same board. would this have anything to do with how we tension our hold down rollers? i don't think they have been adjusted from the factory, but we bought the machine used so i really don't know. would increasing tension give us a better cut? we have an in-feed and out-feed table so i think the pieces are adequately supported.

You should be able to adjust the fence ever so slightly. If it is tailing off towards the rear of the board, move the front of the fence just a little. Do not shim!

google:

One thing that occurs to me is that if you are just buzzing the edge of a board that thick, perhaps the blade is dishing because it is not having equal force applied to both sides of the blade.

Does this out of square occur if you run the board through and have the blade cut, say, about a half inch off of the edge of the board? If the out of square edge is acute from the top face of the board when just buzzing the edge, that may be the reason, and that may account for both of your problems, the out of square and the "snipe".

One thing to check as well is to see if the blade is properly supported by the arbor flange and the arbor washer. Make sure that they are both the same diameter, because tightening a smaller relieved washer into a larger one may cause the blade body to dish, thus causing all sorts of problems.

Hope this helps.

tony - thanks for the thoughts. we're normally cutting away 1/2" + worth of material on either side of the board. i'll double-check this, because that might be part of the inconsistent results we've been getting.

Talk to several saw blade makers to see what type of blade they recommend for that machine. I know that with the Diehl machines, the blades were important.

However, the "glue line quality" typically comes from the tracks/chains and how they are capable of holding the lumber.

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
