Thanks Chris, glad you like that jig!
I forgot to mention that I use the jig to put a
secondary bevel on my drawknife. If yours is really beat up, I recommend hollow grinding first. I grind to almost a feather edge before I hone. Peter Galbert (again) has a really good homemade dry grinder jig for doing this. He has several versions:
Here is the quick and dirty version, which takes about 5 minutes to put together. Chris, I know you love your dry grinder, so this should be a natural.
Here is a much fancier version that I've never tried, and
here is a video of that version.
A number of people have mentioned that a drawknife is really easy to hone freehand, once you've hollow ground. It totally is. I made the jig because I think it's faster, easier, and safer, and if you are drawknifing for 5 hours and stopping every 30 minutes to hone, speed and repeatability is an issue, and not having to think about cutting your fingers is nice too. But to each his own, of course.
