How to sharpen your bandsaw blade in one minute.

Dull blade making the bandsaw vere to one side? Use diamond sharpening cards to sharpen your blade.

[@rsc4peace971]

just came up on your video and this certainly makes a very logical yet not intuitive method to salvage a dull blade. I will definitely try this to extend some of my resaw blades that are no longer cutting straight on wide boards

[@4kbirdpalace628]

On a 102" blade I literally sharpened every tooth on a 6tpi blade like a swiss army knife saw blade, a high alternating bevel...took almost 3 hrs. but there are few blades on earth that can compare in cut quality. No more offset teeth that are not razor sharpened. I'll cry the day it finally breaks LOL.

[@chrisstewart8259]

It makes sense in a way. But this method only removes any dulling on the extreme upper edge of the blade. It doesn't clear out any hooking that may be in the gullet of the tooth. It'd be a good quick fix sharpen to get a job done or to get the last few hours out of a worn blade if the local wood shop is closed. But if it works, it works!

[@STMwoodturning]

I’ve used this technique before and it helps. I’ve also used Richard Raffan’s method and it works better but neither are as good as a new blade.

[@EJ42955]

Is it really 'sharpening' the teeth, or raising a burr on the point of each tooth? I would be curious to see a magnified image.

Nice tip. Thank you for posting. I use a small (75mm X 15mm X 30mm) fine stone that I keep for just my bandsaw and use it as you used your diamond plate. Works good, too. It's also handy for applying to the rear of the blade to get rid of sharp edges thus allowing (especially for some of the smaller blades) ease when cutting small circles. Regards Doc from Australia.

''...i don't need a donk, i've got a band-saw....'' Atta boy Doc !

[@JackWilson-b4f]

Thank you. Great tip for an emergency sharpening while waiting on a replacement blade.

[@chris_thornborrow]

And that the key - it works temporarily whilst you wait for the new blade - its NOT a long term fix.

[@jimbo2629]

Really interesting video. I have in the past used a diamond stone to correct drift. If you overdo it you lose too much kerf. Best solution is to keep a second new blade in the workshop. I guess it’s comparable to honing planer knives in situ.

[@derekmccullagh7866]

Thanks ,great tip . more please looking foreward to seeing you again.

[@chris_thornborrow]

More to come!

[@MichaKrasowski]

I love your content! Keep up the good work Chris

[@chris_thornborrow]

❤ nice to see yoi here Michal- I know your family has experience with KZbin so Im honoured.

[@johne7100]

Thanks! I'll certainly try that.

[@ypaulbrown]

new subscriber here...wonderful,,, cheers from Florida, USA....Paul

[@johnford7847]

If I understand correctly, you're sharpening one side of each gullet. Do you have to repeat, tilting the plate to dress the other side also? Any tracking issues after sharpening in this manner? It does seem like a useful technique. Thank you for sharing.

[@chris_thornborrow]

Its useful as is, I only dharpen one side and you get a terrific burr on each tooth.

[@pathardage1880]

Thanks for the tip.

[@chris_thornborrow]

No problem!

[@alandisomma-od5fz]

You can clean the metal off your diamond sharpeners by wetting with lapping fluid and an ordinary pink school eraser.

[@chris_thornborrow]

terrific, thanks

[@petersack5074]

....or soak in strong vinegar, overnight.....

[@davidmiller6010]

Method I was shown was to stone the sharp side for a couple seconds. I'm guessing this is actually adding some sharpness back in. I've got no excuses really, since I tend to keep 10-20 assorted blades on hand, and just stop being lazy.

[@totterdell91]

having sharpened many hundreds of bandsaw blades with a dremel and a diamond cutoff wheel, I'd have to say "brilliant effort" and I see no reason not to give it a go. I will also add though that if you give the teeth a clean beforehand, it will make a difference. A blade with dirty teeth from cutting say acacia melanoxylon will heat up a lot and blunt the teeth much faster than a clean blade. I use a cordless drill with a brass wire wheel chucked in it for cleaning. I run the direction of the wheel "with" the teeth, from both sides. As it happens, I will be in a position to test this technique out tomorrow on a couple of laguna 14" machines which have both hardened steel and bi-metal blades installed. I imagine Richard Raffin might put in an appearance, so I will get his opinion on whether he likes the result, while I am at it

[@bjornpeck268]

There are many tips on how to clean blades, including strong solvents. For most hardwoods you get very good results if you put the blade in hot water a minute and brush off the dirt. Often it is the sugar in the sap that makes it stick and it is easily revoved with hot water. The wheels are also cleaned with hot water, a brush and a piece of wood with an edge.

[@user-wl7rb5ri5m]

Someone was thinking.

[@debralegge8513]

Great tip. Thanks for the video.

[@sharonbrown3666]

Great tip, thanks

[@lancelanphier9509]

It would be nice if you could Pan the camera so we could see what you're even doing

[@chris_thornborrow]

yeah I need to get better you are right - sorry, please bear with me.

[@johnduffy6546]

THIS, I've gotta try

[@Tony-o1b]

Nice little trick

[@joberthalib9951]

Great tip my friend. Look forward to seeing more from you.

[@chris_thornborrow]

My next one is a donut chuck !

[@alessandrosuppini943]

Thank you for sharing! 👍

[@chris_thornborrow]

No problem 👍 more on the way!

[@bentontool]

I wish I could get my bandsaw to runs backwards, then do it under power!

[@zapa1pnt]

Just turn the blade around.

[@bentontool]

@@zapa1pnt- I am a lot duller than I realize... I should have thought of that! 🤣

[@Jestey6]

Done manually just appears to be a lot safer🤕

[@bentontool]

@@Jestey6 Yes... agree...

[@magicone9327]

Sharpening the back side of the tooth?

[@WiresOutMyEas]

are you not just sharpening the back of the teeth with this?

[@ianthemonkeyhangerturner]

i would say that is all wrong you get a better job if tou use a dremal tool and run round the gulet to sharpen them

[@Gazr965]

Can't see it working very well, may buy you 5 mins of sawing.

[@RobRobertson1000]

Yes, it is the surface inside the gullet that actually does the cutting. Like yu say, helps for 5 minutes at best.

[@chris_thornborrow]

Like I said in the video, Ive ordered a new blade but this gets me through until it arrived.

[@natewu2442]

The volume is way too low. I couldn't hear half of the dialogue.

[@JS_Precision]

It takes two to tango. And to have a dialogue.

[@AA-69]

I let my children do this ,But easier if you wire the motor to go in reverse 👍

[@michaell397]

Well now, I have these exact low cost diamond stones for ruffing. thank you for the tip. will be using it today. ;

[@ZOEng99]

Fairytale wood. Fairytale solution

[@chris_thornborrow]

I prefer to think of it as Magic.
