Ergo hand sanding?


Eric Estlund

Recommended Posts

I have reduced my hand sanding time, and subsequent hand fatigue by alternating between mechanical sanding and hand sanding. I only work on smaller blades (12 inches or less) so someone who routinely works on larger blades will have to sort out how to do it. I use the mechanical sanding to go across the blade and the hand sanding inline with the blade at the same grit as just done mechanically. This means hand sanding out 220 grit scratches with 220 grit, a much faster and easier job than trying to hand sand out 220 grit mechanical scratches with 320 grit. I move to a finer grit by machine, a much faster job than moving to a finer grit by hand.

 

So my standard process is machine sand to 220 grit and lay the blade out at the hand sanding station. Still using 220 grit put a 220 grit finish on the blade.

Move back to the machine at 320 grit and take out all the 220 grit scratches. Back to hand sanding at 320 grit and put a nice 320 grit finish on the blade.

Continue upping the grit on the machine and finishing by hand at the same grit.

You take less time and use far less hand pressure. Not to mention I use a lot less sandpaper too.

The 9-inch disc is my primary finish sander.

I'm pretty sure that on a larger blade I could make the 6x48 work.......

I started doing the same thing a couple of knives ago, but I just use my 2x72.

That will work as well. I just find that the disc makes flat grinds really flat.
