Jointing on the Shaper


I need to make a lot of 3-1/2" X 36" X 3/4" out of poplar.
I am thinking of mounting a piece of flat 10" X 96" X 1/2" aluminum to my shaper table to be able to power feed the poplar to straighten it. I would feed with concave edge next to fence and since each end of the board would be in constant contact with the fence ( holding it in position) it would seem to be able to straighten the board.
Any thoughts ?

i do this all of the time with a spiral head in the shaper and an offset fence. used to use a clamp-on straightedge, now i use the Aigner digital, adjustable offset fence. it's a good way to get a terrific finish and a consistent width (... if you don't have a moulder).

If you need a lot, get a straight line rip to get the one good edge.

Yup, a great and safe way to do this. Remember if you're using a shear cut rebate block for this, it will leave a slightly convex surface on your edges. Not sure if that would matter for what you're doing or not.

Jointing short pieces on the shaper should work well.

1/2" x 10" x 96" aluminum is not the best choice. You are looking for stiffness in two planes. As a fence and in bending across the shaper table. Your 1/2" piece will probably sag. You would be better off to simply joint a piece of hardwood like maple and use that as the fence. Glue a thicker piece to it outside the powerfeed to make it stiff in bending. Definitely wax it.

Stiff shop made fence 6 ft long
1/16 laminate on out feed end with cutter adjusted to outfeed end.
Power feeder . Production edge jointing all day long.

Thanks Adam; I was re-thinking the aluminum as well. I was considering 3/4 baltic ply but I like your maple idea better !
I just happen to have some.

You are welcome. In all of my years I've never jointed parts on the shaper. We've sized a million feet of stuff but never jointed.
Thank you for that idea.

If you need rigidity, make the fence a box section, not a single board.

make a plywood sled whatever length you need. Mark a straight line underneath and attach a strip sized to engage the miter slot in the shaper table. Cover the top with durable coarse sandpaper roll. Center the feeder on the spindle. The pressure of the feeder will keep the piece from moving, clamping or fence is not needed to guide it (although set the fence just out of play for safety). Cheap quick and effective, especially for the short pieces you are machining.

Jointing works well to a long out side fence using stock that has been cut over sized. We have a straight line rip saw that is very good BUT some lumber has built in stress that is relieved when sawn and results in a crook.

a 36" long piece could easily be done on a jointer. If I were going to try that on a shaper I'd use an outboard fence. In that way the contact edge against the guide isn't cut off on the first pass and might result in a straighter edge.

Might be better to use the same principal but with a table saw, long outboard fence and a power feeder. Your pieces are short, should be easy enough to do.

    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).
