    Has anyone seen (or even better, used) one of these jigs to do square grind on their chain grinder? I’m a novice when it comes to square filing and it’s been proven to me time and time again that whenever I invest the time to do it, I rock my chain pretty hard after the fact :hair: I much prefer the performance of a square ground chain to round, so this seems like a good solution. I can’t justify buying one of these jigs, but being a toolmaker by trade I can make one. I already made the 45 degree angle piece. Before I make the rest of the components I’m looking for opinions. Thanks FHC crew.

    I still haven’t heard or seen anyone using this. After discovery, it just kinda fizzled away.

    The chain I rocked yesterday needed a ton of work, and it was already worked pretty well from converting it to square file from round. I ended up going buck wild with a Dremel to clear out the gullets. By the time I got the carnage on the top plates to disappear, they were considerably shorter. I figure this could be a good chain to experiment with.

    If you would want a chain ground on my Simington to have, just say the word and I’ll get you one. That might ease the curve getting your wheel profiled.

    Thanks, much appreciated. I may take you up on that offer... There are quite a few online videos on how to use these jigs, and I'm no stranger to form grinding, but this is a little intimidating.

    Dude on AS was building it and looking for feedback a year ago. Seemed honest and open to ideas/perspectives. A couple guys on our fb sharpening group use them. Limited angle adjustments and manual wheel dressing, but it’ll make a square chain with a round grinder with some practice

    Thanks for the input. I think once the wheel geometry is dialed in, the way to go would to be turn a wheel in the lathe and send it out for borazon coating. Either that or make some kind of norbide stick wedge-shaped dressing contraption for standard grinding wheels.

    Merry Christmas to me :whistle:
    Seeing it firsthand I’m glad I didn’t spend too much time trying to reverse engineer it from internet pictures. There’s an added angle (about 5 degrees) that I would’ve completely missed had I continued on. I’ll give an update once I get into it and become successful at grinding square chain.

    I was going to ask you about this a couple days ago. The YT vid showed up on my suggested the other day and remembered you were talking about building one. Keep us posted. :yes:

    I would like one, but our Super Jolly grinder has the hydraulic clamp...
