Surface finishing belts and deburring

How new is the talc belt? Searching the incredibly slow 3M site reveals almost nothing. The only info I could find is the link below. Click on the item just takes you back to the main abrasives page.

Purchased 2x72's from TruGrit and had them delivered to EconAbrasives in Frisco, Texas.

Econ has the equipment to produce a flat seam and seal the split longitudinal edges - they make belt under their label to sell.

Excellent workmanship, excellent.

Sent Don B and Mark R their belt(s) about a year and half ago.

Have (1) unused 1x42" here in my office - if you need or want it let me know.

R S Hughes may have a stash some where in their system? 

The 3M rep (who ever he/she is?) can order for individual accounts at very reasonable prices when their distributors do not stock.

Mr. Rupert, have you ever done any tests to try and figure out if, or how well how well these belts deburr without abrasive compound?

Are the belts just basically a soft, fuzzy material like a polishing wheel? If that is the case, I assume their major function is as something to put compound on. Soft fuzzy stuff doesn’t have much impact on steel!

I, HAVE NOT DONE ANY TEST - zero.

The nap is short about like one days face growth for me - how long is that?

I suspect they may work for you -

They have worked for me  - again no "Grepper" scientific testing - zero.

Look at your PM box

May depend on the steel and that burr Mark says fell off.

Again I like marks diamond rods system - the radius of round rods may be better than my Spyderco 204 flat (triangular rods) the diamonds are long gone at the corners.

I've been using 3M surface conditioning belts for many years. I have them all. Even a couple talc belts from Mr. Rupert.

They aren't for deburring. I haven't even heard of that, except for the talc belt. I thought it might work, but it didn't. It straightens out a burr like a clean buffing wheel.

I thought I might have the perfect compound for the talc belt. I've had a bar of 16u diamond buffing compound for years. It's very expensive, as it contains a very high concentration of diamonds.

I'm sorry to say that didn't work either. I really wanted it to work, but the belt wouldn't hold the compound long enough to make it cost effective.

Surface conditioning belts do their job. They do a good job of re-conditioning scratched up blades, sometimes making them look like new.

I haven't found them useful for anything else, especially for the cost.

Surface conditioning belts are cool!  I've made some beautiful satin finishes by using a coarse belt for depth and then finishing with a fine grit belt belt for a smooth satin feel finish.  That type of finish adds grip and also resists fingerprints.  

Using conditioning belts, it's possible to create some freaky optical delusions.  Check out this thing that I did on stainless tubing.  When the light hits it, it appears to be horribly bent and askew as though it was run over by a truck.  Actually it's perfectly, absolutely straight.

   

I did it by grinding each of the the tubing segments at opposing 45° angles.  Using a clock face for reference, from left to right the top half is ground from 8:00 to 2:00 and the next lower section is ground from 10:00 to 4:00 and so on.  Even under close examination the illusion delusion confusion conclusion of the mind's eye persists!

   

Who knew abrasive belts could be so much fun?  It would be fun to do that on a knife blade.  Awww... too bad your nice knife got all bent up dude!

OK, never seen that before.

That is pretty cool Mr Grepper!
