Hello Peter,
nice to see you here also!

My Burrly Sane for Woodworkers has notchable pieces only. The level is 138. I believe this is the highest level for notchable 18-piece burr designs. You can find the design on http://puzzlewillbeplayed.com/18PieceBurrT/BurrlySane/Woodworkers/ . It needs three kinds of wood and a routing pattern on t...

Hi Scott, There's nothing wrong with what you're doing, as long as you respect the intellectual property of the designer of the burr you make. If you are making multiple copies to distribute, you should ask the designer for permission. By the way, where can I find the Facebook page you mention? Rega...

I think you have two puzzles:
- the 12 (!) identical pieces are an Altekruse 12 puzzle;
- the other 6 pieces form a standard chinese cross puzzle.

Best regards,

I really would love to take another up to date photo of my collection now, but it just takes so much effort to get them all out into one place and then back again.

Light conditions are normal, just inside light in the house. In two years time I haven't noticed much dec...

I always like a challenge, and a challenge it is to name your top 5 of puzzles! My choice might not be for the most difficult or lengthy puzzles. I appreciate the uncommon, the surprise a puzzle offers. Where does that lead to? Most certainly Cutler's Blockhead is on my shortlist; I've often enjoyed...

So many beautiful puzzles!

Full level is 7.4.4.5.1.2.1... or 7.4.3.5.2.1.1...; it depends on the order of the pieces. BT searches for a shortest sequence of moves to free the first piece. So, the starting position for further analysis can vary.
