Vermeer Yellow Jacket Stump Grinder Teeth Sharpening with Diamond Wheel
Вставка
- Опубліковано 22 чер 2022
- New diamond plated grinding disk made for Vermeer Yellow Jacket teeth. purchased from Thorvie International. I am not sponsored or paid to make this video. the reason for this video was to post something so others can do this as when I searched for some help....no videos available.
Excellent video. Had no idea a wheel like this existed. Have only seen a flat wheel used and the result from a flat wheel is inconsistent on the radius. In the USA, there are guys who advertise sharpening yellow jacket teeth. Simply ship the teeth to them and the return sharpened. The cost of the sharpening is good, but the freight is significant due to the weight. I have used a local sharpening guy for quite a few years, but the marginal results and cost have made me look for alternatives. I tend to run the teeth a bit too long and have lost the ability to sharpen both faces on enough teeth to simply make up two sets of teeth that can no longer be indexed to the second face. Thanks for providing the source for the wheel.
Good video. Thanks for making it.
Cheers
Man this i must have thank you for taking the time to do this video i live in the UK so i may have problems finding one thx again all the best
You're welcome. Glad you got something out of it. Cheers
Thank you sir
This has convinced me to go with green teeth if I get a Vermeer. I use the regular Leonardi teeth on my current grinder and I can sharpen all the way down to a few mm left of tungsten tips. By the look of these there would be at least half of the tip on either side still there and you would either be compromising its strength or hitting the pockets instead of the tooth...
I don't know what you mean. The tip could never wear down so it hits the pockets. Maybe you don't know how these teeth work. However use whatever teeth floats your boat. I use yellow jackets have for 15 years and have had no issues with them breaking, sharpening etc. Go green if you want.....they are simply sharp teeth. Cheers
@@jimmygreen50 around the 4min mark when you find the example of a tooth that is worn down too far to sharpen, looks like you have about 10mm either side of the centre line, I would be wanting to use that down to 2mm either side. To do that you would have to grind the tooth back as far in as the mounting pin, which would cause the compromise in strength or end up hitting the pockets instead of the teeth. Leonardi have similar tip and body shape, but as you wear and sharpen, you just pull more of the tooth out of the pockets to get your distance from the wheel and pockets. If I can find some pics of mine that are really worn vs new I will try upload and tag you or comment here
@@jimmygreen50 just uploaded a clip for you to see a brand new tooth vs a worn tooth, I would even get a few more sharpens out of the worn one. Should be on my account in the shorts
Sharpened those stump grinder teeth years ago. Used a big silicon carbide face wheel on a large twin spindle grinder
I have used the green wheel in the past and it works but it takes some time and accuracy. The diamond wheel is dummy proof....yes much more.expensive but shouldn't have to replace in a long time.
Appreciate the info just got a SC30TX Vermeer grinder. So trying to figure out a few things
Nice machine but heard a bit underpowered. I like the tracks tho. My 362 has been a workhorse
@@jimmygreen50 just talking to a friend of mine that's putting a 35 horse vanguard on his Sc252!! Might do the same with mine
I'd stick with Kohler honestly. Briggs has been ok so far but not as smooth running. My old 252 with the Kohler was never an issue. But so far vanguard has been a good engine
@@jimmygreen50 yes, he has a bigger Kohler I would like to do that with
Hi Jimmy do yellowjackets need to be sharpened to a specific angle?
I stick to the existing angle on the tooth. I think as long as it's slanted as before you should be good to go. I have not had any issues to date. Sharpened teeth are about 90%. Not as good as a new tooth but pretty close.
Hi again Jimmy
Could I please ask you to measure the the inside diameter of the cutting grove?
My yellow jacket are 0,77 inches wide but the webside states the whell is made for tooth that are 0,75 inches wide.
And are you happy with the gritt marks on the tooth after grinding with a 40 grit diamond abrasive?
I wonder if 60-80 grit would be better. But it would mean longer grinding times.
I'm from Denmark and I will have to order from a company here in Europe. The import fees from USA to Denmark are unfortunately just to crazy.
Kind regards Max
Hi Max.... I did not measure it but it is slightly smaller than the stock size tooth....I'm assuming this is to resize the tooth to sharpen it. Mine seems to fit slightly tighter when starting the grind which makes sense. I would also assume the disk does wear over time and become wider so the tighter fit compensates for this. As far as the grit goes....it's fine...the teeth come out sharp and no heavy grit marks.....I have not noticed any issue with the end result. I will say the end result after grinding the teeth is very acceptable. I will also say I grind about 30 stumps a week on average of all sizes and have not had any issues with unsharp teeth. As with any blade they don't last forever. So I will replace teeth after 2 sharpening max.
@@jimmygreen50 thanks again. I appreciate your help and advice.
Hi friend, thanks for the video! Would you happen to know the name of the teeth holder and the model of the grinding wheel? Thanks!
Go to the website. Thorvie.com I believe. They are tooth specific wheel description. It's a 6" wheel made for yellowjacket teeth.
Hi bud, where do i purchase this wheel and tooth holder jig from?
Thorvie.com.
Looks like its working ok. How many teeth do you think the wheel can manage to sharpen before it’s worn down?
So far I have ground about 120 teeth give or take double sided and minimal wear on the wheel. So if you add up the cost of these teeth less the price of the wheel it's paid for itself 2.5x already with lots of life left on it. Really hard to say but I would expect 400 plus maybe more?
@@jimmygreen50 that's sounds pretty ok. Thanks 😊
@Max Nielsen no worries. Fyi i had all the same concerns when looking for an alternative to buying new teeth every time...simply based on the cost....very expensive but worth it in my opinion. It's saved me at least $1500 so far and could go 3 to 4 times that.... depending on how long the wheel lasts. We will see. Also I paid for it with my own money....I have no affiliation with the company. Cheers
Where did you get this wheel for cutting yellow jacket teeth
Thorvie.com
Has anyone suggested you grind carbide wet?
Breathing that dust is a bad habit
You can run it wet yes...but I'm sure it's a mess. Need a special tray for that. I use a respirator when grinding.....just didn't when I made the video. You are right carbide dust is not good to breath in. Always wear a mask and eye protection when sharpening. Cheers
good day! how many stumps are approximately enough for a new tooth ?
I can usually grind about 10 to 15 stumps (30 to 40 cm) with a set of teeth depending on if there's rocks etc....sometimes more....larger stumps depends on the soil....but I have ground some big 100cm stumps without hitting anything and teeth stay sharp.
Is that holder piece really $600+ or does it come with the wheel?
The holder and diamond disk comes as a package for around 650 usd .... The wheel can be bought separately for around 75 less I think. Check them out Throvie International. I have no affiliation with them....just found it by googling around. There are 2 companies selling the same disks it seems around the same price.
What grinder wheel is that? I didn’t see it in the link.
Just ordered one for myself. $985 CDN. I figure that’s about 160 teeth to break even.
I haven't added up what I have saved but I have sharpened about 20+ sets of teeth so far. At $260 a set that's about $5500. Worth the money! Still going strong ... I have minimal wear so far. I was thinking it's rediculously overpriced but in reality it will save you thousands in the long run. Cheers
Ahhhh, it's a NO for me. Going to take that tooth, place it in the vice, take a flat file and work the rounded backside and then give a few passes to the top portion until I have a sharp (90?) on the tooth and that will be good enough.
Lol. Well have fun. Might take you 10 x longer but have at'er
Ive tried to get to their website but it seems to be blocked by IP2 Location Country Blocker whatever that is, does anyone have an email address?
