Hands up all those who have heard of this serious abrasive, which comes in sheet form or belts made up to any dimension, with grit equivalent rangeing from P120 to P2500…..
Hands up all those who have used this , and what can you say about it?
I recently went on an abrasives recce, being tired of the inferior stuff (Usually Norton, made in Australia, to a standard below what I was familiar with)available in the typical hardware store.
I was given some to try and have found it to be most impressive.
Scarey sharpsters take note: this could be beyond your wildest dreams-be careful.

The company I work for have some (limited) of the belts for the Dynabrade belt sanders. Use them to break the edges and finish the titanium parts after machining that go in aircraft. Best use is on tough and hard materials like Stainless and Titanium.
Not sure of their use on the typical metals woodworkers play with. My bosses don't like to let the employees take samples home to play with. Can't for the life of me understand why.
I have used TRIZACT extensively for polishing solid surface counter tops (Corian). A gloss finish can be achieved without compounds. It uses diamond abrasives suspended in a plastic base. The surface is shaped like pyramids which continuously exposes new abrasive as it wears. It works best wet, so I have never used it on wood. It clogs very quickly when used dry. It would probably work well to polish finishes to a gloss.
Any idea where one can buy small quantities of these?

I suggest you Google Trizact abrasives and go from there...Philip Marcou
I did that yesterday but didn't have enough time to really get serious.

Hi Philip
I just saw your post.
I have a couple of belts for my bandsaw from a local manufacturer (he probably buys in the belts in rolls, then makes them up).
This dates back a few years when I built jig for the beltsander to grind plane blade bevels. I also obtained a few belts for sharpening, 1200 and 2000.

2000 grit sandpaper used in a SS setup is capable of a very fine edge for a blade. When this is moving at 1400 rpm, it is like the grit has been made even finer! I was getting excellent edges off this setup - a true sharpening machine rather than just a grinder.
The reason I stopped sharpening (as opposed to grinding) with the beltsander was that it took too long. There were too many belts to change ... 120/240/600/1200/2000 .. even if each was only used for a few seconds.
The Trizact belts are very durable. I still have mine and they are fine to use after a year of use.

"I was getting excellent edges off this setup"
You see now...I am waiting for my belts to be made up.
I like the stuff-compared to silicon carbide papers held in the hand or on blocks this stuff is light years ahead. No more self destructing after a few seconds use.....No more bits of expensive paper all over the place...
Derek, why don't you make a simple three wheel belt grinder for high speed honing purposes that takes these belts?Philip Marcou
