Cutting Half LapsBase frame attachedBase Frame Attached

Here at 2Sand.com our Downdraft Sanding Center build finally moves forward again! Things have been very busy and the build was put on hold for a bit, but since I think Santa will be bringing us some cool new casters for Christmas, I wanted to make sure that the carcase was ready by adding the base frame for the wheels.

Continuing with our theme of inexpensive construction, the frame was made from “two-by” stock, jointed and ripped to 1 1/2″ square stock. Since we know that the downdraft table top will overhang the smaller cabinet body, I wanted to insure that the wheels be set beyond the cabinet front and back to add stability.

So two of the frame members are 24″ long to extend a few inches front and back. The other two are 32″ so that the sides and back of the base are positioned on top of the base frame members for maximum support. These dimensions allow for the fame to be half-lapped together. Half Laps are simple but very sturdy joints that will take the stress of rolling the cart around and working on the top. The ends of the longer parts get half-lapped and the shorter parts are lapped 3″ in from each edge or 18″ on center.
