I’m peering over that slippery slope of saw sharpening. I bought a MF saw set along with some other paraphernalia. In the MF box were these shop-made, apparent “angle jigs”. I haven’t measured the angles yet. I plan on sharpening a couple of 12 PPI cross-cut saws at 15 degrees, and I’m pretty well set up to do that. How are these jigs used in saw sharpening, if at all? The size may suggest a lower PPI saw, say 4 PPI rip. Just a WAG.

I don’t see your entire tool set for sharpening, so I’m poking in the dark here. I consider a saw vise as important as the file. If you don’t have one, get or make one. That would be one of the first things.
Then read as much as you can about saw sharpening. LJ “Brit” is an expert and he just posted a short “to do” list for sharpening. He will answer any question.

Saw sharpening is one of those areas where a little knowledge leads to misplaced confidence. It’s what you don’t know that will sneak up behind you and smack you in the head. So spend a lot of time with differences in sharpening options: rip vs crosscut; fleam, hook and other filing angles. It takes a LOT of practice to do it well, so be patient above all.

Those little widgets found in the box remind me of gauges used on forestry saws. Being home made it’s really hard to know what the maker had in mind.
