On reflection and my long journey and many dollars spent I would not start with using a jig because things have changed and sharpening a flat blade is so much easier these days because of it. I would never criticise anyone for using a jig but using the hollow grind/mini bevel method I don't think it is necessary. When I was honing the whole bevel I had to use a jig but the hollow grind has made it redundant.
Go to Derek Cohen's site and look at his hollow grind set up and method, a bench grinder with a suitable tool rest and a CBN wheel does the grunt work and the primary angle is set with that. Place the blade on the stone of choice lift slightly so the heel of the grind is clear of the stone, lock your arms and in effect start rocking back and forth with your whole body. Yes, you may stuff up the first attempts but don't get to carried away and throw the chisel at the wall because you are working such a small bevel any mistakes can be rectified very easily, five seconds on the grinder and you are back at go again. To repair a full rounded bevel caused by bad technique would take a lot longer than that.
The aim here is to get it sharp, the slight lift and the angle that you sharpen at are not critical. You could put a magnetic digital angle indicator on it if you want to get some idea but I never have and my results chop wood nicely and cut fingers equally as well. Go to Derek's site and have a look at his set up, it works and that is all that matters and when you get the practice it is the fastest way to sharpen a blade from scratch.
