Engineering 101 Coping Saw

Received an email today from Henry Eckert, who are the importers of Lie Nielsen Toolworks. It was promoting their new integrated site www.henryeckert.com.au.

One of the items that caught my eye, was the coping saw from Knew Concepts.

Looks just like a saw that could have been designed as part of a mechanical engineering course. I’m sure I designed something like this during my degree in Mechanics of Solids!

That does not make it a bad thing- it is all about load transfer, and this allows significant blade tension while minimising weight.

Add to that the material of choice is titanium, so even thinner sections are achievable while maintaining the same strength.

All this leads to being able to really tension up the blade, and as Knew Concepts claim, to achieve notes unheard of from coping saw blades. (Plucking a blade to hear the note it makes, and therefore get an idea of the blade tension is a common practice). The more tension, the greater the beam strength, so the blade is less likely to twist in the cut, allowing tighter corners and more accuracy.

Allows things such as this exceptional work by artist D.R. Halliday, entitled Masonic Coin

Talk about reinventing a basic tool!
