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!

MagSwitch in the V8 Development Series

With the 2013 series of the V8 Championship about to get underway, and in a new format with multiple manufacturers finally able to participate once again, the development series is also kicking off.

On car #35 in the Dunlop (development) Series, driven by George Miedecke, MagSwitch has made a reappearance down under by becoming one of the car’s minor sponsors.

Their logo can be seen just behind the rear wheel.

Welcome back MagSwitch, we missed you! Time to come full circle and appear at the woodshows, and/or bring out more innovative products. We’ve liked all the ones in the past, and there is still plenty of scope for further developments for woodworking products. (Still haven’t seen my MagBroom!) I know MagSwitch is still available in Carbatec (among others), but a limited range, and I don’t think it has been actively promoted since the last time I was demo’ing it at the woodshow.

There have been some new products, mainly for industrial products. There is a larger MagJig now, and MagLatches (I got a very early version of it a few years back) are now available, just not down under.

Still want an I beam in the new shed, with a chain hoist, and I’d love to have an MLAY lifting magnet to attach. Not sure what I’d lift with it, just cool to have! Being able to swing the tablesaw around the workshop perhaps!
