Thread: Bandsaw sharpening

The firm is Henry Bros.

Hi Shedhand,
Why go to Sydney, when we have McDivens in our back yard.

McDiven Saws, 328 Kororoit Creek Road, North Williamstown 3016. Ph. 9 397 1458.

Wood not go anywhere else. All they do is Blades for Bandsaws.
Ring up, order your blade size & blade of preference, Great Mailing Service.
I just buy a 2375mm 3/8in. x 6TPI for a 14in. B/S $12.50.
Then I Sharpen my own Blades. Takes around 18Mins. Nearly Sharper than a new one.

Thanks for that mate. Just rang them. I will get a new blade or two but they don't sharpen blades and definitely can't do anything with the buckled Resaw King blade. So I'll have to send them all to Henry Bros. 3 blades worth $410 bucks so I'm not tossing them unless I have too. I've used them in total no more than 40 hours and none of them have been resharpened yet. An expensive lesson learnt I'd say - if they are deemed dead. ☹️ Not happy!

Why not sharpen your own blades? It is really easy. I've been doing it for years freehand with a Dremel and a cheap diamond wheel.



I leave the blade on the bandsaw and just stroke the back of the tooth, pulling the blade down. It takes about 20 minutes to sharpen a blade on my Hammer 4400 (17 1/2")
Here is a jigged version ...



An alternate approach (which I used to use) is with a bench grinder, using the side of the wheel ...



Look at the clip, especially from about 3:00 minutes onward.

Hi Shedhand,
We in Vic. Have very competent Bandsaw Blade Manufacturers. So why go to Sydney.

McDiven Saws Pty Ltd, 328 Kororoit Creek Rd, Nth. Williamstown 3016. Ph.9 397 1458.

I have bought Blades off them for many years. Very good Mailing Service
I buy a 2375mm. 3/8in. x 6 TPI Blade, $12.50. My blade is just run of the mill.
I then Sharpen my Blades in about 18mins. & almost Sharper than when new.
That was a lot of money for that Good Blade, so I hope you can get it repaired.

Hey Derek. Well today I tried what you suggested and sharpened one of my bandsaw blades. It was already off the Saw so I sharpened it on my Multitool bench grinder attachment - the 50 mm belt @ 120 grit. I carefully and lightly touched up the back of each tooth and it took about 15 minutes. I then fitted it back onto the Saw and did a test cut on a 125 x 125 lump of river Red Gum. Produced 4 beautiful 6mm veneers. It cuts better than new. $80 saved. Like you said it was dead easy. Just need to be careful that the grinding belt doesn't eat to much. Next task is to sharpen the Carbide Resaw King which is a bit more difficult. Will report back. Thanks for the guidance.
cheers

What the others said, I sharpen mine by touching up the back of the tooth on a bench grinder. Fine for blades around 4tpi or less, would be tricky in finer blades.

Spotted this little beauty last weekend took the video

blade sharpener and Kerf setter just $600 for the two........no I didn't buy it I use my Dremel and diamond stone.

the one I did was a 25mm skip tooth. I had an el cheapo 10mm which I binned. Too many teeth and very worn.

Found this interesting - would like to what those of you with more history or knowledge of new blade quality and sharpening skills think.




BTW Derek, love that method you posted, thanks.

Thanks.

That's one of the videos that taught me the method some years ago. The difference between that that the bench grinder video I posted is that one grinds using the side of the wheel (the one I posted), and the other uses the face of the wheel (yours). When I first started grinding, I used the face of the wheel. It is more difficult - the blade curls up and you have to twist it around to grind accurately. The side of the wheel is easier. But easiest of all is to take a Dremel to the blade while it is on the bandsaw.

Yes, love the Dremel method you showed, will definitely be doing them that way. I was also wondering about his method of testing and the huge difference that sharpening made to a new blade, got me thinking about just how good our new blades really are.
