I've been looking at the jigs that are currently available for drilling holes/pilot holes for the European cup hinges. Most are just holes drilled in plastic so that they'd wear out rather…Continue

At one point I had misplaced my Kreg Screw Selector Wheel. So when I finally found it again - carefully tucked away on a shelf to protect it - I decided to create a couple of tables that contain the…Continue

Calculating Screw Penetration Depth

Based on an earlier post I spent some time trying to determine how to calculate the screw penetration depth given the screw length. This is what I came up with:Penetration Depth =SIN(RADIANS(75))*(ScrewLength-(0.073/SIN(RADIANS(75)))-0.48)The formula is shown using Excel format, which also works for Google (Docs) Sheets.This is the depth 90 degrees to the material surface - not along the angle of the screw, assuming that the Drill Bit Depth Collar is set by placing a U.S. nickel (5 cent coin)…See More

Suggestion: K4 Drill Guide Pin with Square Drive

I have a K4 Kreg Jig Master System. With the Dust Collection Attachment in place I find it almost impossible to loosen/tighten the brass (?) knurled screw (Drill Guide Pin) that holds the Drill Guide in place at the correct height setting, and I find removing the Dust Collection Attachment for each adjustment to kind of a pain.If Kreg was to sell a replacement Drill Guide Pin with a square drive inset added - which would allow me to use the screw drive bit to loosen/tighten the Pin - I would…See More

Festool Domino 500

The first thing I will do is set price aside and focus on the tool and why I bought the Domino.
