I am experimenting with making woodworking jigs using the Microjig clamps in which the clamp foot has a dovetail cross section. A jig requires a grid of channels that match the 1/2" 14 deg dovetail. Within SketchUp, the perpendicular intersection of one dovetail channel with another causes Push/Pull to stop. Is there an easy way around this problem?
A second issue I am having is how to draw the stopped dovetail slot that will accept the clamp? The steps in making this channel (or slot) is as follows:
- route a 5/16" diameter stopped slot
- route a 1/2"-14 deg dovetail stopped slot, 3/8" deep
- route a 7/16" dia by 1/4" deep 3" long
I was able to draw this channel but it was convoluted and required a lot of erasing of extraneous geometry. First, I divided the length of the part in half so that I had a flat surface to use follow me on half the dovetail profile. Next, I used Move/Copy and Flip Along to create the 2nd half of the jig base with stopped dovetail. The 5/16" wide stopped groove was then created with Push/Pull.The next step was to widen the 5/16" wide channel to 7/16" wide to a depth of 1/4". The last step was to create the 1/2" diameter entry hole made by the dovetail bit. Thete was a lot of erasing of extraneous geometry. Generally, one can draw something quicker than they can make; it is not true in this case. I am looking for a simpler way to draw this type of geometry.stopped dovetail clamp slot.skp (44.8 KB)
