Most efficient method for climbing to 500 grit

Hey everyone,

I'm looking for improvements to my methods on climbing grits.

Right now I'm going with trizact belts from A160, A65, A45, A30. The problem is that once I try using the A30, it doesn't cut nearly as well as the other belts. It takes a long time to get anywhere and burnishes almost immediately. I dress it often with a file card, which removes the loaded steel, but it happens so fast that I'd have to dress really, really often. It still doesn't even cut that fast. I've tried various speeds and pressures with no real luck.

So far to get to 500 grit, hand sanding is just faster for me. There's got to be a more efficient method though. I'm not concerned with sharp bevels or plunges since on my kitchen knives they aren't really part of the design. My goal is just to get the whole blade to a dirty 500 grit finish faster and then get a clean finish by hand. Any tips?
 
I stop at A45, then hand sand if I want. I know the A45 needs less pressure and a slower speed. I just gently move the blade over the belt and let it cut what it wants to. I typically only use the cardfile when I start.
 
Don-

It's a simple answer bud (just not so simple to do)....

Start getting more time in front of that your 9" disc sander!!! :p :thumbup: :D

Grind your blades with a 60X on the 2X72, go up to a 120X if you want.

Move to the disc with 120X Rhyno, then 320X, then 500X with a rubber or cork backing between the disc and paper. Once the paper starts to dull, hit it with some abrasive belt lube.

You'll be able to start hand sanding with 500X.

In most cutlery grade steels, the cut-offs from making the discs will be enough (or at least close) to hand sand your blades to a clean 500X. :cool:

If you're using CruForge V, 3V, etc. then you might need another 6 sheets or so. :eek: ;)
 
Thanks for the advice!

Nick do you find the disk to be even more effective than trizact or other belts? A fresh rhynowet cuts really, really well but it does dull up pretty quickly. I need to get some more belt lubricant - would any in general work well for that?

One thing I have a lot of trouble with though is figuring out a better way to differentiate previous grits. I change the orientation of the blade in relation to the disk, but sometimes it's still a little tricky.
 
Do, perhaps the Norax engineered CERAMIC belts would be of use to you. I have a reply to a thread just below a bit. Frank
