The design is super simple. I’m not one for over complicating an item. Just two sides and two dowels make up the base. The flipper is just held in place by the tension on the rubber band.

I made this from resawn claro walnut and 3/8 birch dowels. It flips your coin in the the air and you can either catch it, or let it land. Regardless you’ll get a unbiased launch every time you use it!

The walnut is sourced from a place that sells cut off material in 50lb bags for $9. So there is always some walnut in my shop for these small projects. I just love the look of the grain in this piece.

I used boiled linseed oil to pop the grain on the walnut, and really give this fun piece that finished look!

I intend to use it pretty heavily! It does flip it pretty high, I might have to dial that back a bit!! That is just a matter of a larger band.

Funny use, yet beautiful looking at the same time. The grain really is spectacular.

The perfect gift for someone who has one of everything. Sadly I do not have access to 50 Lb bags of walnut for $9.00, count your blessing on that score!

What I would give to get bags of hardwood for that price. nice use of scraps shows that there really is no such thing as junk wood if used carefully.

so many drinking game possibilities, so little time… you should sell these to college kids.

Great idea and execution Peter. Did you consider making the coin holder slot perpendicular to the length of the flipper? Have you tried enough flips to be able to duplicate results? I saw an episode of “Going Deep With David Rees” (NatGeo) about coin flipping and I think the conclusion was that a practiced manual flip can give you 99 out of 100 results the same. I’m just curious if your machine would have the same results.

I had it lying flat in the in the initial model. More like a conventional catapult. The reason I changed it was because I thought it looked better with the slot. I’ve now played two games with it, and it seems quite unbiased. It also helps that we’ve been catching it mid-air and slapping it on the table. It’s fun to do, and I think it adds a lot to the randomness of the toss.

Great looking toy! Is your source for cutoffs a trade secret that you would be willing to share? I am also in Northern Ca so it might be worth the drive every once in a while if there is anything left after you have stopped by.
