First off it’s good to be back after my injury to my back which I twisted a little while ago.Thanks to those of you who asked after me God Bless all of you for being really wonderful friends to me over the last year or so,it means evrything to me as my shops are apart from my wonderful wife of almost forty years Bronwen and my sons Alistair Russell and Ewen and immediate family,including Lucie and Reuben Jay my darling wee grandson whom I adore.Alistair

My woodshop saw man has not been around for about a year .I live in the HIghlands of Scotland by the sea and my nearest big city is a car ferry ride and an hours drive just to get there through thick traffic.This is both time consuming and expensive when you add it up it’s becoming easier just to buy new blades when my expensive blades get dull.So I am saving them up.I recently saw a device for sharpening blades on ebay I have facilities to make a similar device myself and intend to.I just want to check what part of the blades get sharpened ? I know you never relieve the thickness of the teeth so that they always remain the same saw kerf when cutting.I just don’t know if you do underneath where the blade meets the wood or also on top.any advice or a site covering this would be helpful.Alistair

That is a Very Good link!

With some jigs, one could make-shift a way to do it in the shop!

Good to hear that your are doing better!!
First, I would suggest that you ship them to a shop that is equipped to properly sharpen them for you.
But….If you would prefer to do them yourself, I’ll to to give you a brief outline on how it’s done.
The face of the tooth is ground first. The key to the success is to remove the same amount from each tooth. The grinding equipment that I have used, uses the face as a reference for the next step. Next grind the top of the tooth. It is very important to take the exact same amount off of each tooth.Taking different amounts from each tooth will change the height of the tooth and effect the quality of the cut.
A carbide blade is engineered so that each tooth will make a controlled cut, any variance in the tooth size will affect the cut.
You are right, the sides of the tooth are not ground during a regular sharpening.
I hope that this brief explanation helps.

Glad to hear you are back with us. I have a trick back, but mostly it just limits the amount of time I can stand up. But I have been where you were with the back. Ouch.

I have never considered sharpening blades since I have not been that heavy a user. Easier for me to buy new ones… no info from me on the subject…...I am betting no one in Alaska sharpens saw blades.

Alistair glad to see you back. I was wondering whether the recent floods in Scotland had anything to do with your absence on LJ. A few days back garden tender jroot posted a forum topic on his visit to Scotland with a beautiful slide show. I very much remembered you after seeing it and was about to send you PM but lo, here you have shown your presence. Pl take care of your health to finish your pending projects. With love to all members of your family.

Glad to hear you are better Alistair and now back online. I guess a lot of us older guys have bad backs from overdoing lifts and doing all the work by hand that they use machines for today. It’s a curse but not a killer, so we can be thankful for that at least. When it comes to blade sharpening, I have to agree that for an inexperienced person, it is probably better to send it in the post to a professional. However, I can appreciate your desire to do it yourself. If you decide to give it a try my suggestion would be to try it on an old blade you don’t really need, and see how it performs before risking your best blade. Good luck whatever you decide.
