As I intend to build my own grinder, I would like to hear what the most popular belts are (size/length? Manufacturer?) to purchase on the web as they would probably be the cheapest ones. According to the belts – I will design my machine. Where do you guys buy them will also be good info. I will be glad, of course, to hear any other tip or idea in case I have not thought about something or so. Thanks a lot – Michael.
 
If you can go for it a 2" X 72" grinder with a 10", 12", or 14" smooth wheel and a flat platen say 2" X 7" over laid with ceramic glass will work very well. Buying cheap belts to me is like throwing your money away. Dull belts not only don't cut the steel but actually destroy any good work you have done be they in course or fine sizes. A cheap belt just wears out in a hurry. I use 3-M, Norton, and Hermes. The sizes are 35, 60, 120, 65, 40, 30, 16, and 5 or 6. Frank
 
2"x72" has to be the most common for knifemakers.

Like Frank said, cheap belts are not worth it. A good belt will last much longer, when you factor out how long the belts last you are actually paying less for a more expensive belt.

I now use Norton and Klingspor belts. But from what Ive heard here on the forum, Im switching exclusively to Norton and 3M. I buy my belts from Trugrit.com, another common source a lot of people buy from is Supergrit.com.

As said above, 2.x72 inches is the knifemaking standard, but:

Considering where you are from, if you build to that you are committing yourself to buying from US sources forever.


In your area of the world, metric sizes are probably the norm, and it may be easier and cheaper to import metric goods locally.

Contact your local industrial abrasives supplier and discuss the belt types you want and the sizes available.
 
2x72 is a very good size to start with. Having said that I have been using a 6x48 for the last 9 years and it works very well. I use it for surfacing also since you can lay it flat. 6x48 also has a very large selection of belts too.

Also consider that you can cut down a 2x72 to 1" and it is very useful.

I forgot to check the OPs location. Maybe Israel has both metric and english available, but I would imagine more metric. As opposed to Canada where they got both, but tend to stick with Metric.

Or the US where we know metric is easier to use, but we still stick to english.:mad::rolleyes::confused::eek:
