Any nearby Square grinders?

[Lonewolf74]

I’m looking to see if there is anyone in Wisconsin that has a square grinder for square ground chain?

I hand file square but it seems no matter what after several sharpening’s I have different length teeth and of course I’m a little better at one side than the other.

So I’m looking to see if there’s anyone around that I could send a few chains at a time to get sharpened and more importantly set back to identical from time to time…let me know if anyone is interested or might know a guy?

Thanks for you time and help,
Joshua

Hit them with a round grinder that is set up at 90°,then file them. Be sure to leave the shelf in the side plate/ gullet junction to help hold your file.
They aren't perfect off a grinder, but closer than most will ever make them. Make sure you set your depth gauges with a progressive style guide.

Thanks for the help so far guy’s!

Chipper1, I don’t have a round grinder either but I suppose it would probably be pretty easy to find someone to do this for me.

Another idea I’m playing with is buying a new Simmington square grinder and see if I could get some business sharpening square ground for local guy’s to help pay for the machine.

Anyone be interested or think there could be a market for this? I know there’s a number of loggers and tree services around.

Kevin @huskihl was grinding chain for hire until his porting backlog grew too long to mess with it. The market is limited, there are plenty of chainsaw dudes that have never seen or heard of square ground chain. I'll just add that shipping a square grinder is risky business. Factory packaging is expandable foam. It might take half an hour to open the box.

Where in Wisconsin are you located? I have a Simington, but I don't use it much.

 

[Lonewolf74]

I’m in central Wisconsin near Berlin

 

[kurtz]

I’m in north central wi. I’ve got a Simington. I don’t want to get into the sharpening business but I could sharpen a few chains for you if you would be able to wait a week or two for me to get the time.

 

[Lonewolf74]

Kurtz I definitely appreciate the offer and yes waiting a few weeks would be perfectly fine with me. I’m not looking for this to be an all the time thing but just to get some chains straightened out here and there and hand file in between. Once I have 4-5 chains I want ground I’ll get ahold of you and figure out how to get them to you and all that if that sounds good to you?

You can get a fair amount of chain in a postal flat rate box.

That works for me. I’ve got a raker grinder also so I can set them wherever you’d like too. For felling and limbing I’ve set them at the same depth as the stihl file guide and it works out pretty well.

Kurtz, thank you again for the offer I really appreciate it. Farminkarman has offered to help me out occasionally as well and he lives pretty close by so I’m gonna go that route for now but I’ll keep you in mind should something happen.

Alright now for a question I have based on a response I got in this thread.

What is a progressive vs (non-progressive?) depth gauge? The raker guides that you slap in at an angle to sit under one tooth and on the cutting edge of the next tooth like the one attached to the husky roller guide or the WCS guide is the only type I’ve ever used.

 

[huskihl]

The ones that lay down on an angle are progressive. It’s been proven that .025 on a new chain cuts much better than .025 on an old worn out chain. There was a fella from Australia who had quite a milling operation and realized that 6–7° of down angle from the cutter to the raker works better than a fixed number. So the further the cutter gets filed back, its raker needs lowered more yet. .025 rakers on a new chain cuts similar to .035” rakers on a chain worn back to the witness lines. Progressive gauges take that into account

Also worth noting that a properly maintained chain that is filed back to the witness lines with those rakers filed down lower so that the saw feeds on its own like a new chain, cuts a whole bunch quicker than new because of cutting a narrower kerf

 

[Duane(Pa)]

The forward lean on the side plate angle on square ground chain has a substantial affect on how the chain feeds.

No problem. You’ll be in great company.

Bought it a few years ago from Laona Machine. It’s a real time saver.

This is the first time I’ve read an explanation of a progressive guide that made sense to me. I even bought one a while back but didn’t really understand the strategy of it. I gave it away because it was awkward to hold and fit poorly onto some chains.
