Squarejig

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 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.

Want square chain with a round grinder?

 

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

 

It was YOU that gave me the idea over a year ago
Sometimes these things take a while before the ball gets rolling.

 

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.

 

huskihl Kevin, have you heard or seen anyone using it?

 

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
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.

 

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

 

Did anyone ever get one of these I got one and it definitely works good

 

I cut hardwood so I started with a “durable” grind….there is plenty of room for a more aggressive grind if I need….i wan this chain in my 362 and it cut great!!

 

Also I put the jig on an Oregon 520 and it works great!!

 

How you liking that jug, have you used it much yet??

 

So far so good. I've sharpened probably 2 dozen chains with it over the past year. No regrets.

 

That’s great!!!

First off what grinder do you have it on??!

Mines on an Oregon 520….

What angles you using I started with my base slide at 2, but I have don’t the last chain at 5, it was more aggressive…

I do -10 for right cutters and +10 for left cutters the top plate adjustment….

I haven’t tried the tilt yet!!!
