I'm not sure if these have been brought up before but thought I'd put a plug in for them.

I normally shy away from the more expensive products but was in the mood to try something different and also wanting to step down in grit size. I was using 50 grit Norton Hoggers which remove alot of material but then spending a heck of along time removing the scratches that these belts left behind. I went to the 3-M Cubitron abrasive grain in a 80 grit and I'll never go back. They also say you'll get double life out of these belts, I find that to be quite the understatement. I'm still on my first two belts but have mainly been using the first one. They were priced at just over 7 bucks each but I was able to get a break with 10 belts so it brought the price down to just over 6 bucks. I'd say even at 10 bucks each there still a deal, but I won't say that cause they'll most likly raise the price..... Thought I'd share this, if this is old news just ignore it...
 
Raymond,

Thanks for the recommendation. I just ordered a set. What I didn't know is that they are a structured abrasive. Although you implied it. Can't wait to try.

I guess I need to change the order in which I surf the net. I finished up placing my online order for belts, THEN came to the forums and read this post. Oh well, next order. Thanks for the info.
 
I got curious and found this on Cubitron:

Metal oxide modifiers (La2O3, Nd2O3, Y2O3 and MgO) are added to these particles by the impregnation of their respective nitrate solutions. These particles are then calcined a second time to remove volatiles prior to final sintering at a temperature between 1300 and 1600°C.

Actually there is a little interesting stuff in there about grinding with it:

I agree,I was useing the 977 and was having a very hard time getting the scratches out so I tried the 967 80 grit and they are alot eaiser
to get the scratches out with them
 
I really like the Cubitron belts.. I think the 80's work just about as fast and as long as the 60's.. In any case I like em..
 
I have been using these belts for awhile and I won't go back either, I like the 967, 60 grit. I get them from Pop's too.:D
 
Great thread. I don't even bother with 36 grit anymore--way to hard to get the scratches out. I am interested in the 60 vs. 80 grit in cubitron. Are you all using something before these, or are your initial grinds done with these grits? Also, what do you clean these up with in terms of both grits and manufacturers?

Thanks,

John
 
John,
I use the 60 grit, then I switch to a Klingspor 220 grit J flex belt then to a 400 then to a worn 400 with belt grease, from there then you can hand sand to a satin finish. This works for me. :D

80 grit 967 to a norax x100 to a norax x30,then to hand sand
you will be hard pressed to find a better belt to take
out scratches than norax belts.sometime if the 967 is worn
I will go right into the x 30,it saves alot of time and alot of money.
 
I agree about the Norax. I primarily flat grind and never did have much luck with Trizact belts. But the Norax are great.
