Tool Test: Knew Concepts Titanium Fretsaw




The truss system of the backbone
appears to be like curious, however it works gangbusters.

The loopy design of this titanium 5″ woodworker’s fretsaw from
Knew Ideas is, I feel it’s honest to say, the very first thing you
discover. However use it and also you’ll shortly come to understand that
the construction helps to make it light-weight and inflexible, and the
intelligent tensioning mechanism snugs up the blade tight – and
retains it there.

This body is a redesign of the corporate’s earlier titanium
woodworker’s fretsaw, the body of which was  a steady
piece of 1⁄eight″-thick titanium (the identical design because the aluminum
woodworker’s fretsaw at present out there). However in an effort
that was initially meant to scale back supplies waste and take
benefit of extra available 1⁄16″-thick  titanium,
designer Lee Marshall got here up with a riveted truss system for
the noticed’s backbone that’s much more inflexible than the unique (he
calls it a “birdcage noticed,” in honor of the Birdcage Maserati).
The backbone is riveted to  1⁄eight″-thick titanium arms.

Additionally worthy of be aware is the blade-clamping and tensioning
mechanism. On most fretsaws, the blade is pinched between two
plates at both finish. When a noticed is correctly tensioned, these
plates want to carry the blade tightly; they sometimes don’t
(and it’s fairly irritating when the blade comes free within the
center of a reduce).

All Knew Ideas saws have a small plunger and anvil mechanism
that grabs tight on the blade with little effort; get the blade
positioned accurately within the blade slot, then flip the orange
knobs to lock it securely.

And the tensioning mechanism is simply as easy to make use of; it really works
extra just like the tension-release lever on a band noticed than the
typical thumbscrew association. Set it simply wanting excellent by
turning the knurled brass screw, then a cam clamp results the
last pressure. Flip it towards the noticed’s arm, and you’ve got a
tight blade that may “ping” properly for those who pluck it. When the
noticed isn’t in use, launch the stress to increase the blade’s
life.

One other intelligent function is that the blade-clamping mechanism can
swivel left or proper and lock in detents, from zero° to 45°
(although 90° can be good) – fairly useful when eradicating dovetail
waste in the course of a board that’s wider than the noticed’s
armature. And whereas the noticed I examined was a pre-production mannequin
and didn’t embrace this function, Marshall tells me he’s added
indexing positions to maintain the swivel in place when pressure is
launched. Is huge deal? Probably not, however it does imply the
noticed will keep in the identical orientation you final left it, so
there’s much less fiddling.

At $225, the Knew Ideas titanium noticed is definitely an
funding in your work – however it’s also the most effective fretsaw I’ve
used. The corporate additionally gives a tremendous aluminum model (with a
steady body) for $95.
