Adequacy of shaper for stacked tooling

1/17/15

I would like to stack two shaper heads for doing coping on a 1 inch spindle 5HP 3 phase powermatic shaper. (Model 26PS).

The shaper bodies are insert tooling about 5 inch diameter. One of them is a steel head and one is an aluminum head. They are both the same diameter.

I have successfully set up both of these heads individually on a 3/4 inch arbor import shaper in the past. They are currently stacked on a 1 1/4 arbor 10HP SCM shaper. I would like to repurpose this bigger shaper and have the smaller powermatic is presently idle.

My question has to do with the viability of stacking these on the powermatic. Do you think this machine would be stout enough to support this much weight on the 1 inch spindle? We are only removing coped ends, not running big profiles.

Most shaper spindles are stackable.
1'' should be adequate for that size stack and a 5hp motor is large enough for a small cope/tenon cut.

I would check the spindle runout before spending the time of setting the machine up. If the runout is within tolerances and the bearings seem good then you should have no problems.

I would set the cope head as low on the spindle as possible, with the profile cutter just above it. The cope is usually a harder cut, and less likely to whip around when placed low on the spindle.

Check the dovetail ways in which the spindle rides. These are notorious for wearing badly on these shapers, and will let the whole spindle wiggle as a result.

I agree with David, although the Aluminum cutter head would be better on the top if possible, If you use a PanelCrafter for Coping then you will definitely want the coping head on top.

If your Cope & Stick heads are different diameters then maybe you should try to source a second machine with a dedicated sled because you will have offset problems trying to stack mismatched tooling, I would also consider the smallest diameter heads possible to reduce overall vibration and too heavy inertia on a smaller Shaper such as yours.

Good Luck

One of my fantasy set-ups is a shaper with one spindle, two sets of cutters, and one side of the table set up for coping, and the other side built up for profiling, with feeder, etc. I say fantasy because I've never gone further than thinking about it.

Conceivably, two people could work the same machine at the same time. Crack that whip!

The fence is the hard part....

David,

What you are looking for is not terribly complicated to produce. One of the guys on this forum has actually done this for a door company he owns.

Stacking spindles is a great way to reduce set up costs. We've been successfully selling only two profiles my whole career. You can either have it as a shaker style or with an Ovolo. We picked Ovolo over Ogee because most window and door sticking in our neck of the woods seems to be Ovolo.

We have a pair of copes on one machine and a pair of sticks on another. This works well for us because the machines are essentially parked right next to the wall. I would like to drag these closer to the whirlwind because it would better facilitate a three person door cell. I have to move some other machines to make that happen but it is on the list.

Our lumber is fed with a tractor feed power feeder with the lumber passing between the spindle & outboard fence. This allows us to also do dimensioning as we stick. We currently use a vernier scale to set dimension but would like to convert this to positive blocks for repetitive dimensions.

The optimum machine would be set up similar to a castle pocket drill. You would feed the rails into the bumpstop until it engaged the bumpstop. At this point an air clamp would come down to hold the material and another air piston would push it through the cutter head.

    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.
