    Wooden Puzzle Lock For Secret Door

    NICE!!! I see a few extra combination suggestions to make this more secure, since currently it wouldn't take long to try all combos, but I would suggest:Changing the L- joint for a gear and teeth; so that rotating the knob would move the pin left or right instead!This could be added to the current design even after being built, would give way more combinations. And has the added bonus that it could be changed (lift gear, slide pin, drop gear) in case anyone works it out by watching you!Obviously add numbers/symbols round the knobs as your code :-)Just a thought, great as is though.
