Review on Transparent Template Instrument Geometry Woodturners by Oso Mears

This is one of the many examples of a smart device that I first saw in one of the many YouTube videos on woodturning. It is designed to find the center of a piece of wood being turned on a lathe much faster than the traditional method using a pair of spacers. The print is good, dense, the cuts are clearly visible. It only has one major disadvantage: Like almost all copies, it is made of acrylic. Acrylic isn't very flexible, which is a problem when trying to route very uneven pieces. It's also relatively brittle, which means it can crack with use, especially if you drive a nail down the center to mark a piece. Acrylic also yellows over time. The original product from an Australian lathe tool manufacturer is made of PETG which is much more flexible and durable. If you find this template useful for turning, I suggest you look for a more flexible material.
