I have a boatload of 6×6 posts that need to have the corners chamfered (but not the entire length – chamfer starts and stops mid-post). I know I saw a homemade jig and technique at some point in the past in FH, but I’ll be darned if I can find it now when I need it. Anybody know what issue it was in or where I can find details on such a jig??

I should think you can just stick a chamfer bit in yer router and have at it- use the bearing or yer edge guide. Mark stop and start lines and approach them slowly.

Yup. I'll sometimes nail a stop block on with 18ga brads if I don't trust myself to stop a router in the appropriate place. The scrap stop block usually pulls right off over the brads easily enough and then I just yank 'em with end nippers. First time the posts get wet, the brad holes are gone. I'm assuming we're talking exterior here with the 6x6's.View Image
skib,
I did a house that had 24 6x6 exterior posts that needed chamfering.
Since they were all the same length I made 2 "U" shaped jigs that slipped over the posts and clamped in place. The jigs were made up of scrap plywood and ran from the end of the posts to where I wanted the chamfer to start.
No measuring after the first one, I just aligned the jigs with the ends of the posts and clamped, routered and with one roll of the post and re-clamping the jig and repeating I was done.
You can chamfer with the router riding on the side of the posts, but you end up with asymmetrical start and stop cuts, because the router bit is wider at the top (obviously).
What I have done in the past is to make a jig that straddles the corner of the post and use a flat bottom mortising bit in the router. The jig is such that the router rides down into the cut to start, and then rides up out of the cut at the end. The bottom of the bit does the cutting.
If you're a real Victorian purist then you use a chisel to cut the start and stops, so there are no curves.
