Topic tags/keywords: blade

So, I have some discarded lawnmower blades that I’m looking to cut up for use in homemade tools. Now, these are no ordinary little push-mower blades, these clearly came from something heavy duty, as the steel is 1/4” thick, maybe more.

Is that too thick for a plane blade? I was thinking of using it for a Krenov-style scrub plane. (I’m also considering a drawknife, but I think the thickness is just fine in that application.)

Follow-on question… would an angle grinder with a carbide cut-off wheel be enough to cut this stuff up? I gave it an obligatory attempt with a hacksaw, but that is clearly a losing proposition… I’d be running through a ridiculous number of blades.

Metal cutting abrasive blades will cut it, but beware of the heat generated. It will affect the temper and hardness.

Mower blades are usually not very hard because they have to withstand huge impact loads without shattering. Nobody likes to see chunks of mower blade coming at them at 200 mph.

The thickness will not work in most planes that I know of, but you could make a wood body plane to hold whatever thickness you have, I suppose.

Should make a good froe.

Have your say...
