Thread: Buzzer blades

Hi John
For years I have used a grinder with 80 grit aluminium oxide wheels, but getting dead straight free hand is not possible. Recently I have tried a method described in various places including FWW. I have fixed various grits of abrasive paper ( 80, 120, 150, 320 I think) and use that to sharpen. Works surprisingly well. Must get some silicon carbide paper though.
I use the 2 wooden sticks method (common). I have posted a discription here in answer to a previous query if you want to read it.
Cheers

Mate I take it your talking about the blades in your Lab30..
I too got sick of paying big dollars to have them sharpened, plus I was not impressed with the quality of the job I was paying for. So sharping my own blades was another reason why I bought a Tormek sharpening system. Not cheap, and it will take me a while to pay it off, compared to paying someone else to do it. But the quality is up too myself and I can do them as often as I like instead of waiting for someone else. I use the blade setting jig that was supplied with the machine. But I wasn't getting good results & also didn't realise that, until I took a little more time and care one day when I was setting them, this was after myself once slipping while setting the blades and then needing several stiches So was probably a blessing in disguise....?

Oh one little hint, dont over tighten them grub screws!!! Don't ask how I know either

Cheers

Thanks for the tip on the Lab30 Shane,I have a spare set of knives that I had cut down from a 15" thicknesser that I sold off so dosen't leave me stranded until I get around to sharpening the old ones.
The knife grinder is one heavy sucker with the knife set in a jig that slides in a lateral motion whilst winding the grindstone up to meet the knife blade which has a cool running 60 grit white wheel which also keeps Er'indoors happy as she reckons she'll get all her knives sharpened now,but I told her steak knive don't handle too well on this machine and so she will have to find other means to cut up the Visa!
Cheers

A tip for sharpening.
The grinder you have will be fine, but you need to finish the edge. I use a wooden jig that the blades sit in on edge. It has a ledge for a stone to run along set at hone angle needed (actually have three jigs with different settings)
As you carefully hone you will also notice if your grinding is acurate. If high or low spots appear you need to ajust the way you grind (its in the feel and the eye)
To set the planner I have two ironbark sticks graduated with 1mm marks that give you excellent indication of blade setting.
Keep sharpening! its the secret to great results.
