Turning Celtic Knot Baby Rattle Compliant With Safety Regulations

https://www.AsWoodTurns.com

After a club demonstation on baby rattles, I decided to turn my own. Club demonstrations are a great source for inspiration to expand or refine my turning repetoire.

More than a plain baby rattle, this rattle features a three loop Celtic knot following a process I developed several years ago. My three rules for Celtic knots are:
1. Perfectly index cuts;
2. Perfectly maintain stock orientation
3. Perfectly replace removed wood.

My process allows for any number of loops opposite the common 2 or 4 from square stock and it adapted for table saws and band saws.

However, government safety regulations also apply to baby rattles to prevent fatal accidents with babies. Both section 1501 and 1510 must be followed. 1501 is a test for small parts. 1510 is a test specifically for baby rattles.

I 3D printed a test fixture for baby rattles. It is downloadable from www.Printables.com (https://www.printables.com/model/4388...)

My rattle is 4.5 inches long and 1.5 inches diameter, finished with beeswax and mineral oil. Popcorn kernels provide the noise source.

Enjoy.

p.s. If you would like a more in depth demonstration than my weekly videos, please contact me for an IRD (Zoom Demo) on this or other topics.
