Can you get a 600 grit belt at, say, Lowe's? Or do I have to go online to get that? I haven't been down there yet, I just got the belt sander yesterday at harbor freight and I didn't see any belts fine that 120 grit, but considering that I can get up to 400 grit paper at Lowe's, I'm holding out hope that I can get the belts too. (Might just be a fool's hope, we'll see.)
I kind of figured it would sand really quickly, so I was planning on starting with an old rusty knife that I don't care if I destroy, maybe see if I can find that old rusty machete to start with. The palm sander works a lot slower than the belt sander, so would the 400 grit paper be reasonable on there?
I can get a reasonable edge with stones, and I don't even have nice ones, I just don't like to work that way because I'm really not the greatest at holding a consistent angle between different stones. I'm not terrible, just takes a bit of concentration and it's kind of a PITA for me. I kind of figured this might be the shortcut that would make it easier, other than putting down the money for a system that hold the knife at the right angle.
On that note, are there any videos that show how those systems work, I've always wondered how they worked, since the knife doesn't have just one straight edge, they always have curves in them that require moving the knife.
