Getting started in chain grinding

A good machinist/tool grinder can sharpen anything !!! Except a dull mind ...

 

If it is who I think it is, he's an idiot. I'd never do some of the stuff he does, just a total waste of time. LOL

 

Probably right, you wouldn't drop a barn on yourself would ya?

 

Not more than once! Some guys will do anything to get off work.

 

4th picture down... the green grinder is the tecomec? We had that same one at the shop I used to work at always seemed to by pretty straight forward, who knows if I was doing it right. I asked the other day does the direction of wheel rotation matter ? As in grinding into the cutter or out of it if that makes sense?

 

You went ....there?!?

 

No the Nielsen is the green one. It is used for rakers only.

The pics after the Nielsen are the Tecomec conversion. In the 2nd & 3rd pic you can see the "before" pic of the Tecomec.

The Silvey is bi-directional and you should get a better grind by turning into the working corner, but it is not the end of the world if you don't. If the wheel is turning towards you it is also throwing dust and metal shavings at you too. The saw shop I frequent has two Silveys and they run both away from the operator and have a PVC pipe hooked up to a vacuum system.

 

Well the door was open, might as well kick a man when he is down. He is a pretty strong farm boy and that would be the only way to get the best of him.

 

Man!! Tough crowd here tonight!!

 

Remember, I still went to work the same day. 5 days later when they said I had broken Vertebrae I decided to lay down for a while. LOL By the way, Nice talking today with you on the phone and good to be getting back. we're just having a good time here guys.

 

Loving the input from everyone so far. Life got in the way of grinding progress.
I've also used up my .043 Pico chains to grind on. They were borderline used up and I made scrap of them but learned alot.

Only ones I have left still cut wood and that's how they will stay till the new year.

Lesson learned. Don't try to create hook on chain designed to not have hook....at least not as a noob.

Here's a 50 50 bourbon and coke for y'all.

 

In this pic are you working on the rakers? I would say try to "learn" on your 3/8 chains. Everything is slightly more demanding on the smaller chains. Less room for error if you will...

 

Is the drink to quench and temper the hot cutters in after grinding?

 

No. I was just drinking. No grinding.

I am taking your advice. Gonna try a 3/8 and not go so deep as mentioned earlier.

 

I like Duane(Pa)'s advice. Master your most popular choice, and then modify/adapt to the others. 3/8 chain is everywhere and easy to obtain

 

Hey fellas. Since this is for the noobs trying to get into sharpening chains, could you tell us a little about machine brands and prices to get started.


(I'd like to get into sharpening, mostly because my favorite dealer ground half the cutters away on a like new chain last time I got one sharpened)

 

I have this one. Same as an Oregon 511. Seems to do a decent job.

I would buy a full sized one and stay away from the "mini" sharpeners. All are pretty much the same thing and are made in Italy by a company called Tecomec, (including the Oregons). They clamp on the driver below the cutter which is the basic flaw to the design but in the grand scheme of things isn't that big of a deal. All spin a wheel and as long as the angles stamped on the vice are reasonable accurate you will be fine. A person who is adept at hand sharpening will pick up grinders real quick, the concept is the same thing regarding how the file or wheel meet the cutter face.

 

A thing to remember is be gentle with the grinder. They are pretty flexible and forces on the handle can have a big impact on consistency tooth to tooth. Also if you want to try "reverse rotation" use a air hose to spin the fan in reverse, when it's going good flip the switch.
