Is there a jig for the Tormek T7 that caters to cambered hand plane irons or do they just have to be sharpened freehand?
you don't need a jig....use the regular square edge jig and when you get to the end of the pass and half the iron is off the edge of the stone....grind a little extra here. Then do the same at the opposite side. Also press a little harder with your fingers when at either of the edges.
This will produce a symmetrical camber allowing you to surface plane or cross grain plane without corner dig in.
For a normal camber, I agree with Rob. You can actually affect the edge geometry quite a bit just by paying attention to where you apply pressure.
For a radical camber such as a scrub plane, you can make one yourself like this:

Nice Mike......just the letters LN get me all gooey inside :-)
Thanks Rob and Mike. Looks like a great result Mike, and the jig looks good too for more radical camber.
