DIY knife parting tool from an old table saw blade

 






















Tools and materials I propose:

Angle grinder

Metal cutting discs

Drill press

Flat file

Propane torch

Belt sander

hacksaw

Chisel set

Block plane

Spoke shave

Mini machinist’s lathe

Jeweler's saw


In this video I make a knife parting tool out of an old table saw blade and a piece of mahogany. This tool is used to part off thin pieces of wood when woodturning. 


I begun by cutting the blade to size with my angle grinder. The angle of the front is 45 degrees.


I then used a file to clean the burrs. 


On the drill press I drilled all the holes needed. 


You can flatten the sides with sandpaper glued on a piece of a plexiglass. But using a belt sander is much faster. You should dip the blade in water from time to time, to avoid over heating the blade. I also used a wood block to help me keep the blade at 90degrees. 


I hardened the tip of the knife. With a propane torch I heat it to red hot level and dipped it in oil to harden it. 


Then I made the handle and glued it with 5 minute epoxy. I made the brass pins on my machinist’s lathe but you can buy ready made ones. 


I shaped the handle using a chisel,  a plane, a file, a spoke shave and my belt sander.


I finished the piece with mineral oil.


It worked really nice. But that was it see you soon with a new project video.
