Screw advance box joint jig plans

The plans include:

I also have a free online article on how to make gears


A peek in the plans

Maximum width of cut is 32.8 cm (12.9"), The jig can cut a whole stack of boards at once. See the specs

The plans are in Metric units, except for drill and dowel sizes, which are in imperial units. You can generate plans in imperial units simply by changing the units to "imperial" in SketchUp under 'model info', but the units will not work out to even numbers like they do in Metric.

Cost: $14 USD or equivalent in your currency

On payment, you will be able to download your plans immediately.
The plans are a 4.5 megabyte zip file (your computer, Mac or PC, already knows how to open zip files)
