My dad has had a B&D hedgetrimmer for as long as i can remember, it is safe to say that is his favorite tool. Problem is, it is as dull as can be. Thanks to your video it helped me get it back to top working order and last time he cut bushes out side you should have seen his face light up when it went through like a hot knife through butter, Thanks again for the video Mark.
I never knew how to sharpen my hedge trimmer blades! I thought this video was very helpful but wouldn't use a power grinder because it's a little BIG! I would my Dremel Power Hand Tool because it's easier to handle and it has many grinding tools you can use for those small areas hard to get at. Thanks for the great video!
Thanks very much for taking the time to add this video. Sure makes it much easier to do myself rather than sending it out to be done by someone else for a lot more money that a mill file costs. Cheers
After giving my brand new $650 (AUD) Echo hedge trimmers 6 hours of hedging today I appreciated this video! Little tip though if using angle grinder with all those sparks flying around I'd empty the fuel tank first!
trustme don't use ANY grinder... they remove way too much material in too much of an uncontrolled manor. unless your a daily metal fabricator and your grinder is an extension of your right arm, then stick to using a fine tooth mill file. Even if you aare competent with a grinder, don't use a grind wheel, use an 80 upto 120gritt sanding flap wheel. This is far better of a smooth lapped surface finish than a grind wheel will give you and will stay sharper longer. But still! You can beat a good hand finish..... With a fine mill file that is. Or even better use a fine oil stone, these can be bought as thin 5-8mm thick stones at around 10to25mm width and 100mm long.
good explanation. i think i will try your methods on my next sharpening process. this will save me some money and a lot of time. thank you for your ideas. regards, martin from gartln.werkln
I used a DeWalt 120-grit flap disk on my angle grinder rather than a true grinding wheel. It really worked well, and left a finer surface. Also, with the blades off, I was able to hone the inside flat surfaces using a knife sharpening whet stone. I can't find any information on adjusting the distance between the two blades, so I'm probably going to try using a 10-15 thousandths feeler gage for the space at each bolt point. Bring on the hedges!!
Much appreciated. We thought we had to buy a new one already. Do you need to go to "by hand" method when you get down to the last couple of blades because of the sparks or is it still safe to use the grinder. Also do you need to put any oil on them when finished? Thanks a bunch. I'll be thinking of your store when I need new ones.
Thanks for the lesson on sharpening ! I have Craftsman 22' 25cc & I wanted to know how to make the blade move & respond with the throttle ? I pull my throttle & my blade just sit's their ! It's oiled & greased & doesn't cut when trigger is pulled ! What is the problem & how to correct it ? Thank you !
@Mitterxyz Most trimmers should be about the same. The only real difference I can think of is some machines will have a small, rounded piece at the end of each tooth. On this style you will only sharpen the inner parts of the cutter and not the outer edge. Thanks for watching! -Mark
thanks for the great info on the video.. I do a lot of trimming and after a long summer the blade gets dull so I need to get a n ew good file to do it.. thanks Mark
And EweTubio, if you are using a four stroke hedge trimmer, the oil reaching the block could be an issue, but most are still two stroke which use mixed gasoline and oil, meaning there won't be a problem with oil reaching the block.
I found the best way to sharpen is with a Dremel. Attach the grinder on and give each tip two quick passes. Dont grind too slowly or you'll warp the blades.
Thanx Mate, great video, i didn't even know if you could sharpen hedger blades, going to give it a shot. One concern, when tipping the hedger upside down, do you worry about the oil running into the block? Mine is electric, so i doesn't matter to me. Cheers, Tas.
Thanks for this. Well done and helpful! I do have a queskin (just teasing) though. What type of oil would you add into the blade assembly? My hedge trimmer instructions just say "fine machine oil". Thanks!
I would never use a grinder ,its extremely hard to control the amount it removes and also the angle not to mention shortening the the life of the blade.
even easier if your dremel has the flexible shaft attachment and for another 8-10 dollars you can add the chainsaw attachment collar to dremel tool. become a sharpening center :-)
Most likely sap and residue has accumulated on the blades. When it builds up on the surfaces that slide against each other, it will eventually bind them. Blades not only need to be sharp. They need to be clean. Even if the blades still move, gunk puts a lot of load on the engine. Regular use of a resin solvent will prevent this issue. BTW. Do NOT use a power grinder to sharpen like this bozo suggests. This will massively reduce the life of your blades even if you are careful.
PA Lawn Guy. You don't seem to be concerned with the direction the power grinder wheel is turning. Does it not make a difference? Can one sharpen the two seperate and reassemble and then hit them quickly to match?
Hi Jerry, it doesn't make a difference on which way the grinding wheel is turning. You can separate them if you wish them match them when they are back together, but this way is much quicker.
