Hello everyone.
A few days ago, I ordered Viel S-5-M 1/3HP. This is my first 1X42" belt grinder.(It has not arrived yet)
So I have to choose belts. For the grit belts, I think 3M Cubitron recommended by grepper is the best choice. But I don't know about strop belt.
The easiest choice is this.

But I'm also considering a linen belt or an another leather belt.
I want to hear your recommendation.
Thank you.

If memory servers me correctly, the Viel knife rest uses edge leading sharpening. I'm sure you know this already, but just in case... NEVER use a leather belt edge leading with belt rotation into the edge. ONLY use edge trailing with belt rotation away from the edge. Edge leading into a leather belt will instantly catch the edge and at best immediately cut the belt, and most likely pitch the blade back at you.
Having a freshly sharpened blade pitched back at you at 100 mph could could cause severe lacerations, epidermal leakage and necessitate reorganization of your plans for the day.
Thank you for your recommendation. The Surgi-Sharp leather belt is looks good, and price is good too.
May I ask what's your favorite compound or paste or spray using with this belt?
I'll lay down Viel S-5-M horizontally, as Steve B. did.

I use a leather belt for deburring, and so except for special circumstances I don't use compound. Compound is simply a very fine abrasive poorly adhered to and unevenly applied to the surface of a belt and except for polishing I rarely have need for it. I would suggest that if you wish to use compound you get two belts. Use one for compound and keep the other one clean. For me at least, if I want a fine abrasive belt I'll just use a commercially made one. Commercial belts have abrasive extremely evenly applied and well adhered to the surface.
I do break in a new leather belt by applying a thin even coat of light machine oil to the surface. After that I don't do anything to it. I always use the rough side for deburring.
When it comes to compounds I'm not a very good person to ask. A lot of folks like to use compounds and hopefully someone who is more knowledgeable about them will be able to respond with helpful suggestions.

Recently I realized the value of a clean leather strop. It doesn't roll the edge, even if it is used with free hand, and effectively removes oxidation.(I tested with paddle strop) So I will use two or more belts, one of which will always be clean.
Applying oil to a leather belt is a good idea. It will also improve the life of the leather.
What's the commercial belts? Can I ask you for a link?

Sharpco,
Keep in mind that you can have the motor of your new Viel, either fixed speed or variable speed, wired with a reversing switch. If you are not comfortable doing this yourself, a local electric motor shop can do it for you.

You're right. With variable speed and reversing switch, Viel will be one of the perfect sharpening machines. I'll consider it when I receive it.

Seems like I just read Mr. Grepper is pleased with the finest Scotch-Brite belt. Would that be the white one? I tried them, but I'll have to try again.
As far as deburring compounds go, I think plain old 1µ boron carbide works best. I don't think it makes a big difference, but I'll take leather over linen for positive deburring. You will probably want to add tooth after the BC, which is easy.
That was my sharpening solution for the rally this year. No complaints.
