I was inspired by https://www.youtube.com/user/ThinkCleverAndSmart/ videos about LEGO pinsetters, So I made a LEGO Technic compatible Rake Board modeled after the Brunswick A-2 Pinsetters.
The Rake Board should fit perfectly inside a 22 stud wide gap. I believe this is the spacing used in the videos from what I could figure out. But not 100% positive..
Hope you enjoy! Maybe someone will find some interesting uses for it other than for a LEGO pinsetter. Would love to see it pics of peoples makes!
Here's an awesome video ThinkCleverAndSmart made showing off the design! https://www.youtube.com/watch?v=dJAQhi5RD6s
