The hydraulic clamp was the only issue with the 620. The 520 works but I like the lighter springs on the Oregon 410 and Tecomec Jolly Evo.

@squarejig ah. The issue was probably that little raise to the chain it does right at the end. It's a little inconsistent.

@callinbos5945 Hello, I checked the website on our end. Couldn't find any issues. You could try refreshing the the page and if it's still not working you can call in an order. Thank you. 206.850.2700 Have a great day.

Currently they are $320 for the Squarejig and $220 for the Tecomec Jolly Evo Grinder.

Hi Bryan, the 45 degree jig is our number one seller. We're working hard to make more. Should be back soon.

Can wheel with a flat face. Best way to go.

CBN wheel. Stupid phone.

Definitely, the jigs work really well. This video was made before I figured out how fast the cbn cuts. The pink wheels are not really for heavily transforming the tooth. Kind of figured that out later. The vitrified wheel and the CBN are much faster.

Hi Josh thank you. Books could definitely be written about saw chain. It's pretty amazing stuff. CBN wheels are on the way. 40 degree holders are on hold right now until we get some more steel in. Might be a few weeks.

Thanks. I've used the USG and the Simington. They're good quality machines. It's too bad Silvey went out of business. Those are some of good machines too. But yes, the Squarejig setup is quite a bit less and can square grind chain just as good as any.

I try to use a quick tapping to mitigate heat. You're right though. The teeth do soak up a lot of heat. The coarse wheels cut faster and are more forgiving with heat.

Exactly. 120 is the voltage. The 410-230 is the EU version. Same grinder with 230v motor/plug

The 10 degree setting on the dial does not translate exactly to the same angle when the Squarejig is attached. I think it's about 20. It's actually 17 degrees. Just checked. Just past the 2nd notch is 20 degrees with the Oregon 410-120. This may be different with other grinders.

@@squarejig thank you

Hi John, we just received a shipment but have sold out again. Should be back in stock in a couple of weeks.

Hi Robert, the hydraulic clamp on the super jolly I don't think allows the Squarejig to stay held in place. The Tecomec Jolly Evo works great though.

@@squarejig ok I do have a Oregon 511a I think that similar if I’m not mistaken. I did look on the website any idea when the products will be off back order?

@@Robert-in5oq I have not tested the 511a grinder. The jigs should be back in stock in a couple weeks.

Hi Dustin, This is precision made with domestic stainless and cnc machining in the USA. It does cost a lot to make. Would you be interested in a non stainless version at a lower price?

​@@squarejigI'd be interested in one made from even something like Mild Steel or aluminum or something as long as it's still solid and accurate if it'd reduce the price 40-50% I understand there's a TON of overhead and costs in a project like this especially starting out but I'd bet that you'd probably triple sales with a lower cost jig. It's hard for many lower-income folks to justify spending more than it's costs for a grinder just to get a jig to achieve a better tooth shape. I'd bet that people would pretty much quit buying the current variety however

I built one out of 10 gauge sheet metal 4 in squair cut in half at a angle 2 bolts 2 nuts and 2 washers for in-between the triangle cut plates washers need to be a little thicker than your drive links

Yaaa make it half the cost but I stil want it to be accurate either buy a silvey or simington or this fellas American made jig to go along with a 400-500 dollar grinder and ur at about half the money of a square grinder machine so

Right on, thanks Casey. Yeah, the Simington grinders are great. The blue wheels make a nice finish. I've heard the salmon colored wheels are good too but I haven't used one yet. My guess is they are a coarser wheel. The universal grinders have a bunch of different wheels and grit available as well. Anyway happy cutting my friend.

I get them from Madsen's.

Quite a few options on eBay as well - I prefer Vallorbe - seem to be the smoothest cutting. Models 2279, 2276 or 2270.

It's definitely smooth and fast cutting.

I think the USG will require modification for the Squarejig to work so it may take a while.

Gibt es bereits 😉

​@@stephanfrenger1547 servus kann man das bei dir im Shop kaufen?

This is a wheel built specifically for the Squarejig setup. They will be available soon.

@@squarejig are these wheels available yet?

@ss229er7 We're sold out at the moment. There are more on the way.

Hello, yes, the .063 jigs work with .058 chain.

I use a diamond file.

Right on Kirk! Much appreciated thank you.

Thanks! www.ketten-schaerfen.de for most of Europe and Squarejig.com for everywhere else.

It likely makes hand filing easier and may prolong the life of the file to remove the gullet with a round file prior to square filing. However, I don't think it's required to remove gullet prior to hand filing. I like to leave at least 1/8th inch for chip flow on square ground chain or enough that it acts as a paddle to push chips to the bottom of the kerf. I think this helps push chips down to the bottom of the kerf so the rakers can do their job raking out the chips. If the gullet is completely removed chip flow may go toward the rivets and create more drag on the sides of the chain. However, if the gullets are never cut back they could become wider than the kerf and create more drag. This is why I think a happy medium is good. At least 1/8th and not too much that it is wider than the kerf.

Hi Mathew, Yes the jigs are $320.

Right on IndianaDoug! I'm always looking for new and better ways to sharpen chain. You have a pretty cool channel. I'm checking it out right now.

Thanks JK!

Hey Joe, how are you? Anything I can help with?

Thank you John. There will definitely be more video on the CBN wheels. Hope you're doing well.

Right on brother! Love the support. Looking forward to testing this one out at Tazapalooza.

I would just like to say I enjoy my square jig very much and am wondering went the cbn wheel would be available

@@justinr6200 Hi Justin, great to hear. It may be a few months before we have them ready. I can let you know as soon as they are.

Hi David, I did try one. I wish it did work. It requires modification to create consistency on left and right hand cutters.

They're currently $320 + shipping at Squarejig.com

Hi Donald, Yes it will cut right hand cutters to 40 degrees. But left hand cutters will be 50 degrees. Unless you have a grinder able to tilt to 95 degrees for right hand cutters. I think there is a Maxx grinder that tilts both directions. I haven't tested one though.

@squarejig I had a better idea , I have An angle cube (knife sharpening) I can set both sides at 40* by adjusting the base in the grinder clamp.

@@donaldobyrne8309 Yeah, that works too! Very cool.
