Thread: Flap wheels part 2

As it turns out, the chattering I was getting with the flap wheels was partly due to the fact that I had my Dremel on 4 rather than 1, like I thought I did.

So my next question is this: How do you sand the actual blade with these things? I don't have any trouble doing the toe section, but the tang seems to get in the way when I try to do the heel. I am using a flexi-shaft. I'm trying to keep the entire length of the wheel on the blade and rotating off the edge so as not to catch it.

Thanks,
Josh

Josh,
Is this in place of doing the sanding by hand? At what point do you decide to use the flap wheel as opposed to doing it by hand? And what grits are you using? Sorry about the questions!

Thanks
John

Josh,

I do it first parallel to the blade and then perpendicular .....

It gives me faster sanding.....

On the back side, I have no problems as it's fairly natural. On the face side, the first 3/4" or so of the heel has to be sanded with the wheel rotating into the edge. That's very dangerous and you have to be extra careful unless you like getting hurt or even worse, damaging your razor
John, flap wheels are good for cleaning up major rust and minor pitting of your blades. It's much faster than hand-sanding and the 400 grit will give you a rough satin finish, that's passable. I left some of my blades like that, and I finished others by hand in higher grits (600-2000). Hand sanding is for the true perfectionist, even though Dremel finishes also look great (take a look at Jason's work). It really depends on your equipment, patience and expectations. I don't have the patience to spend 10-20 hours hand-sanding a blade lol.

Thanks Ilija,

That makes all the more sense to me now, and I can add some more items to my shopping list

Ilija,

OK, I can work with the wheel rotating into the blade; I'll just stay away from the very edge.

To clarify, this is a hollow ground W&B 6/8. There's a stabilzer on the heel, and I'm having trouble with the handle of the flexishaft hitting the tang and stabilizer when I try to work on the heel. Is there a trick for working on the heel like this, or should I just keep at it slowly?

Thanks for the help so far,
Josh

Just do it slowly. I actually go into the edge when I'm cleaning the stabilizer area and enough of the heel part to put the wheel down flat.
