i was looking a an avergae bench grinder the other day at sears, maybe 45 bucks. the guide is totally adjustable to get the proper angle on the blade.

what is the advantage of a $200+ model?

do you mean the RPM of the wheel? or is it bigger and easier to work with?

did you ever get portuguese? never heard anything?

i run 21" Lawnboys 99% of the time. a few unbalenced blades have destroyed the "drum" on top that the recoils grabs. litterally cracked them. i have now added a big washer under the nut to stengthen it, but i still perfer an optimal balence anyway. here, its cheaper to buy a new balde irather them have them sharpen them... trying to weigh my options this year, maybe buy a nice sharpener.

I have a 12" wheel, 1.5 hp Oregon that spins at almost 8000 rpm. I can do a trashed blade in like 2 minutes or less. Since I do like 40 of them a week, it's important to me...so I can do other maintenance things as well on Saturday.:)

You will definately feel a unbalanced blade on a 21" mower much more over a 60" Z for sure.

Only time I use an angle grinder is to do our brush hog blades...I prefer my bench grinder for the Z's and WB's.

It seems an angle grinder is harder to put a nice edge on with and wrong slip and your taking a chunk out of the blade.

me, being a penny pincher..have tried other methods of sharpening blades. angle grinders, drill attachments.. with the so called guide. major pain the azz, and never "right".
i may jump in to a good grinder. i may sharpen at most 5 blades a week... so it will sit uneasy for awhile:hammerhead:

You can put a decent edge on a Z or WB blade with a angle grinder...takes longer vs a big bench grinder...slip and take a chunk out of a brush hog blade and who cares? 5 minutes into the next job and they get beat up as it is.

Very accurate and worth every penny it costs.And so are their blade sharpeners.We have two magna matic sharperners,you get a perfect angle with the cut off edge as a guide, and very rarely blade burn.

i understand the magnets hold the blade and you can spin it/ right? how do you know if its off slightly? i could never get it up to the operating RPM by hand spinning it??

I forgot it was Yankee Stadium. I should know since my grandfather was a home plate umpire during that era.

Something that I forgot to mention was the single blade on a 20 inch or so mower acts as a counter weight for the flywheel btw...that is why a balancer is so important for that size mower.

i hear ya, i remember trying to start a mower once without a blade on it. i can't remember though, if i shut it right down, cuz it ran so bad... or if i couldn't even start it. i just have this lesson in my head that says, "don't start without the blade on.." i'll go with my gut on tht one.

No no don't spin it, just place the blade on the balancer and pull the magnets to the blade and let go.The blade will spin on its own,when it comes to rest and the blade is balanced the blade will be in this position ---------.If either side dips, that side is heavier and needs a bit shaved off.

I have some pictures of a jig we use to sharpen our blades at work. The blade is set in a clamp like device that slides back and forth across the wheel. The grinder itself is attaches to another sliding mechanism that allows it to be cranked in closer to and further away from the blade. PM if you want the pics.

rod or 6'7 -

with your dedicated blade sharpeners, say you have blades from 3 different mowers that you're using, do you have to adjust the guide on each type of blade?? Or once you're set up, you're set up??

I'm talking about regular straight blades, not the "2-tiered" mulching blades.

there is an adjustment on the top that allows me to raise or lower the wheel according to the pitch of the blade...takes seconds.

Adam,

I can't believe someone was taking potshots at your daughter. That is just ridiculous! Cheap & uncalled for! Why would anyone do that when it's so much more fun to pick on you? :D

I have a run of the mill bench grinder and usually find it easier to sharpen with a hand held angle grinder. I'm doing about 24 blades a week, and that number is probably going up.

so Rod, these dedicated grinders are easily set-up for any particular blade? Is there a "holder" that sets the blade at the right angle, or are you required to hold it like you would with a bench grinder?

With the maga matic , the work platform for place placement has a cut off edge,you use the cut edge as a guide and you get a perect angle .The magna matic turns at higher rpm's, and blade burn is very rare.We have two magna matics and the one in the image will handle all straight blades.

It only takes a couple of seconds Mark to set the correct pitch for a blade. Just set the pitch and feed the blade back and forth. This Oregon that I got spins the wheel at just under 8000 rpm's do sharpening doesn't take but a minute or two.

OK Rod, I guess that's what I wanted to know. So instead of having to feed the blade, and hold it at the proper pitch like you would with a standard bench grinder, you only have to do the feeding, and the pitch is controlled by a rest... correct?

rod,
there is the Oregon model i showed you in that link.. there is also, another step up. for another $50, there is a Oregon model, with the same size wheel (8") and hp (1/2), but has an adjustment knob for the wheel to lower and raise. is that feature helpful, or just bells and whistles.

To be perfectly honest Adam, if you use relatively only one size blade on your mowers, you don't have to spend the money. In my case, I have blades that range from 21, 52, 61, and 72" size. So for me it's worth it since I am lowering and raising the wheel frequently.

It's your call if ya want to spend the extra 50 bucks my friend.

its not so much a $50 dollar increase so much. how much is that really if you're investing in a tool?
but i've learned over the years, that the simpler the set up, the less parts to break and replace:hammerhead: ... example: ever have to replace a heated car mirror, compared to the "old style"? you have to go through your insurance company:laugh:
doesn't the wheel "elevator" compensate for wheel wear?

I have a RBG model made by Wall Enterprises I bought about 6 years ago
that sounds like this one with 1/2 horse.It uses an 8" diameter wheel that is 1"
thick.The pitch adjustment works the same and I can grind any size blade on it.
My god,the 1/2 horse is good ,doesn't 1.5 rip it out of your grubby little hands and throw it through the shop wall?
As to balancing blades ,several years ago we had a 21" commercial Snapper
someboby bent the crank on slightly.We decided to run it as is and it totally
tore that mower up in a season.The vibration wore every wear area several
times faster than normal.I keep all blades balanced cause in my limited
mechanical knowledge I have always felt unbalanced blades can tear up spindles in bigger mowers-especially high lift blades.Spend the $50 and
sharpen some blades for hire!That $50 will be pennies or less per blade
sharpened and WHAT IS YOUR TIME WORTH?

Just bought a magna 9000 and this blade sharpener is fantastic. I mean it cuts a perfect 30degree angle, and will sharpen a blade in about a minute if your angle is already 30degrees. the picture belowis of two blades, the one on the left is when we use to sharpen with a hand grinder, the blade on the right is when we used the magna9000
