But for now..
First you get a saw set or plier like device which can be set to bend saw tooth. To start with you adjust it to one tooth, then go along sqeezing on each of the teeth, to make sure that they all bend out the same amount. Other than finding out that your saw blade isn't consistent at all, it's fun. You don't need the big hammer and anvil type which are used for big two handed saws. These are easily picked up in top shape for a few dollars. On ebay check collectibles, tools, woodworking, saws. Good deal!
Only then do you run this jointer along the blade, to get all the teeth the same height. That's when you look at half of the teeth randomly having flats on top, as they were all different heights... Slick and I paid just a few dollars. A person could just use a long flat file run along the top.
Then you check if the rakers are all the same depth below the teeth with one of these - again just a few bucks. I guess you could use spark plug feeler gauges. I haven't used one of these yet and dread what I will find.

So so far tools are cheap and you can get decent ones. The bad news is that clamp on filing jigs are expensive, so i want to see what I can do with chainsaw filing guides. Saw vises are cheap and neat but shipping kills, so I'm going to have to use a slot sawed in a log and tiny wedges.
The thought on most people's minds is that is getting a bit silly in terms of being time consuming. Just sharpening the uneven teeth with a piece of emery wrapped around a piece of broken hacksaw blade will show LOTS of improvement, though. We'll see about consistent tooth set and height set to optimum later. I saw lots of hard wood, so it might be worth it to me.
I have seen a Veritas saw jointer and edger in the axminster catalogue and I read in Leonard Lee's book on sharpening some very good information on sharpening saws, well it gives good info on sharpening just about anything.
Well worth the nothing that it cost to borrow from the local library
