Would anyone share the proper method for grinding double edge dagges?

I have a Wilton Square Wheel. I am a descent flat grinder. Have not yet aquired the knack for hollow grinding with my set-up. I have made a few "San Fransisco Style" single edge daggers of the flat grind variety.

How do you go about getting those beautiful, even, double edged blades???

I would also appreciate any tips on hollow grinding single edges blades. I believe I have an 8" wheel for my Wilton. Can the hollow grinding be done using the existing work rest or must it be free handed?

First you have to make the work rest 18 inches or longer. Set the angle of the rest so it grinds the angle you or looking for. I start with a steep angle and as I grind decrease the angle to the finial angle. Clamp one or two pieces of one inch angle iron to the blade. The angle iron will help keep the blade steady on the rest. As I get closer to the center line in the blade I go to higher grit sanding belts to slow down the grinding. It took 3 aluminum practice blades before I got the hang of it. Good luck--Ray--
 
not being rude here...but the same way you get to carnegie hall...practice...practice practice...if you keep your grind on one side even the other will follow....in my opinion they are one of the hardest things to do in grinding....cause you have to be super careful and right on to have it come out right.....of course you run a line down the middle right?!...get the template right too....the best way is just make one side and then they will be the same on both sides.
i freehand everything...i think thats the only way you can get the curve right...

i should add...dont try to keep it straight at the end when grinding the first side.. follow the template..then when you grind the other side exactly the same the line will end up in the middle....a little thinner.. down to the tip.
 
I realy don't do daggers that have the grinds "touching" each other, down the lenght of the blade.... I do double edges that the grind lines have to be perfectly even or the knife looks like $%*&#!
I use Dykem Blue and scribe centerlines and grind height lines. I do everything feehand and when I get close to being finished, the layout lines keep everything even.
As Tom said, practice is the the best answer! I've stuck a few ruined double edgers in the tree outside my shop.. in disgust.... usually on my way in to get a beer and watch TV!!
