Chain sharpening...

[Albedo]

When you think about it Mr Wisewood I bet you've done your five strokes with a file and can't see a straight edge. Brush your file over the top and bingo ... there it is. Loads of chain saved by not keeping on filing, and just a quick debur.

 

I have a question for Treequip though.

 

What's your preferred method of deburing, and should we be doing the sides? which I don't do at the moment.

I've got City and Guilds fabricator welder qual's but have forgotten all this.

 

I've been a tree surgeon for 18 years or so and didn't know all this about chrome and steel in chains etc.

 

I have found this thread very educational so thanks to the OP and all the posters who have put some thought into this.

 

Oy! Get your tongue out of my a***!

Right, call me Mr Thicky here...

But, if I de-burr like our teams old man does by running a piece of wood across the chain after sharpening, then why does de-burring not AUTOMATICALLY take place when the chain touches its first wood after a good sharpen...?

If you get a burr developing just push it off downwards with a gloved finger.

My guess is that the direction of travel will whip off the bit of dangly chrome exposing soft steel, so not self deburring. I think the bit of wood is skyhucks weapon of choice.

 

Thanks for the reply Treequip I never thought of that and it will be quicker as I always wear gloves when sharpening due to loads of skinned knuckles.

 

How many r's are there in deburr /deburing by the way?

If you take the burr of upwards the chrome can break at an angle which makes it less durable, breaking it downward onto the tooth body creates a squarer edge which lasts longer, its a small difference but it does make a difference.

I generally use the file handle to de-take the excess chrome off, sorry cannot spell de burr either.

Another way of thinking of it - imagine you have a piece of cellotape stuck on to something. When it's stuck down end to end it's really hard to peel it off. However, if you have an edge of the cellotape sticking over the edge, it's easy to peel it off. The chrome plating acts like the cellotape and peels/chips upwards if too much is sticking out.

Cheers everyone, the mist has lifted

I had no idea cutters were chrome plated, I thought they were just polished tool steel! I understand the benefits of de-burring edge tools like chisels so I guess it's worth doing the same with chain too. Cheers
