    Default Thru-bed material clamping and machining

    I’m considering removing a section of the aluminum bed on my Desktop so that I can cut mortises or tenons in the end of long(ish) stock. Has anyone done this before that could share advice on how to go about it? Methods for vertical clamping?

    It would be great if SB offered a rotating joint for the spindle so that it could be rotated up to 90 degrees (manually) to hit ends of long stock. Aspire would have to offer a way to program it too. Seems like it could be worthy.

    I do it all the time on mine off the end of the table.

    Currently building a machine dedicated to those tasks

    Nice setup. But I just figured out this isn't possible with the Desktop. The sides of the gantry are connected with a plate that runs underneath the machine, and it would hit any material mounted vertically through the deck. I'm glad I took a closer look underneath before removing my spoilboard.

    Bob Dodd WAS working vertical clamping for aluminum by taking the first extrusion off with his older Desktop(with single Y screw running down the middle like mine) see #32 ;

    I know the new Desktops and Max's have dual ball screw on the sides for vertical clamping. And Bill Young is actually working with a factory made jig.
