Well here's some videos that I threw together talking about how to use a belt sander to sharpen a sword. this method works just as well on eastern and western swords so long as they have convex edge geometries. if you have flat or concave (hollow ground) edges you still need to look elsewhere. sorry.
I put these videos in the sharpening stickied thread but I thought I'd post a thread here so we can discuss and ask and answer questions.

Thanks Tom, that looks a whole lot easier than by hand

Thanks, Tom, I have one of those and it does make it a lot easier. With this tutorial, I see how I can improve even more on my technique.

Great video Tom! I've shied away from using my belt sander to sharpen. This was a great demo for people who haven't tried it yet. I have a bigger model that doesn't have a slack area like that, great for removing wood, but won't do my edge geometry much good. I must go grab one of those small models soon. Thanks Tom for the walkthrough.

I have got to get one of those slack-belt sanders! With luck (and co-operation from the Australian Customs Service) my wife will be bringing me two Windlass cutlasses back from New Zealand this evening, and I'll be putting edges on them the old fashioned way, stones and paper. This is so much faster and easier! I love that you get the correct edge-profile automatically. I wonder how much machines like that cost here in Oz?
This is a great resource you're providing for our whole community, Tom. Heartfelt Thanks! (& karma, of course...)
Oh, btw, what you call a "wire edge" was called a "burr" or "burr edge" when I learned sharpening as an apprentice cabinetmaker back in the Pleistocene. Dunno if that's a British/Aussie dialect difference or what.
Cheers

yup "bur edge" is another name I have heard. this machine came with a table and a plate to go behind the belt to hold it flat, and I will use it when I need to sharpen a flat ground sword like my type XVIII late spanish by Windlass until then I have it removed.

Great turorial man, I would also like to ad that eye protection and gloves should be worn when working with any type of electric sharpeners. Also you want to be in a well ventelated room or working area.

Tom, you will get much better control and not risk rounding the shinogi if you grind edge up, In fact in some cases you might be able to make the shinogi much crisper with this technique. It also helps when you can look right at the edge while working. Feel the blade go into the belt, let the blade sharpen itself against the belt using the geometry that is already there, if you muscle it too much you will steepen the edge.

Thanks and +1 Tom. And protection should always be worn when using any power tools,take the word of a scarred, one eyed,old carpenter whose first words are usually, could you repeat that please!

Yikes! you must know a lot more about this than me, being a blacksmith, but this seems like the slightest miscalculation would result in the blade edge grabbing into the belt, ripping the belt, leaving a huge damage to the edge, and possibly yanking the sword out of your grip

Tom, great video, I was sharpening like this, except I use a cardboard wheel at the end instead of the belt strop, but I also learned that I am not using fine enough grit belts. Karma to you for those great and informative videos ;D

Contrary to what you might think, and unless you are pressing WAY WAY too hard, the edge will not bit into the belt and grab hold of it.
