I will look into this. Right now the irons are fairly new and the backs are Reference Surfaces. I could never lap the back as flat as the factory. To my way of thinking, if you hone the bevel side and get a full wire across the edge you are golden. Plus the Veritas PM-V11 backs are stepped. Not sure if that's a plus or a minus. Perhaps down the road when the backs get out of whack by pulling the wire off I'll do it. I'm happy with the edges I'm getting.limestonemike said:As far as flattening the backs of new LN or Veritas tools (or other plane irons and chisels) there is a huge benefit to flattening the backs. Even the best tools need a little work to get the best performance out of them. Flattening the backs is the only way to reliably dial in a sharp edge and will reduce the time needed to regain a sharp edge. I see you are doing some learning through Mark S (wood-whisper), he should be able to explain. I learned from Garret Hack, Rob Cosman and others. Its all pretty consistent though.
limestonemike said:Re the honing angle on the veritas jig, you may just want to use the set-up jig as a rough guide. When you hone your primary bevel, just ensure the jig is set-up so the tip of your chisel or plane iron is in contact with the stone, not lifted above it. The heel of the iron or chisel can just brush the stone, it should not grind against it. If you using the jig to establish a secondary micro-bevel, just ensure it is set up at the correct position before you start (ie not the micro bevel position - that comes last). Lee Valley has a good video on their site on how to use it. You'll find after gaining experience with sharpening hand planes and chisels, you may not need the guides. With time, you'll just sharpen by feel alone.

Take a look at my pictures up a few posts. The MK-II Honing Guide sets the bevel angle perfectly. Slide the shiny little guide on the jig and clamp it tight at the line for the width of the iron. Fit the iron in the jig and move it until it is flush with the guide. Now it's perfectly square. Then loosen the clamp on the jig and slide the iron down to meet the stop on the guide. The stop is set to the angle you want. There are many to choose from. Tighten down the jig on the iron and remove the gauge. Done. Perfect Angle Locked In.
Now, say you want a micro bevel. You turn the brass knob on the axel of the roller. It has stops indexed for a couple micro bevel angles. Done... again
You don't have to look at the bevel on the stone and wonder if it's flat. After your irons and chisels are honed once on the jig subsequent honing will take much less time.
