Lawn mower blades
My lawn mower blades get dinged up real good by sticks and small rocks.
Grinding them takes me a long time, 2 blades, 4 edges. Is there any reason why I couldn't set up the angle in the mill and clean them up with an end mill? I would think this would be a lot faster. I could always grind in the final edge. If this isn't a good idea, then everyone should forget I asked a stupid question. Wayne D. |

I saw one of those programs on cutting devices, and the blades for those machines that eat anything were sharpened with some very simple grinders mounted at the proper angle. But then, how would one test the proper angle on an actual lawn, and how would you know when you had it just right? I'd say that close enough would be close enough, even with a hand held sharpening device. At that rpm, even a blunt edge would cut, but definitely anything with any angle would leave a little cleaner looking lawn, and perhaps even produce a more shredded mulch. Steve |

I think the op's complaint about grinding is precisely because these blades ARE so tough! Milling, I think, would be fine, but my lawnmover blades seem to have some complex angles and twists. But if you can set up your machine to do it, and it doesn't eat up yer end mills, then it might be a good strategy. Mebbe clamping the blade in a bench vise and having at it with a 4 1/2" angle grinder would be effective, as well. As time alluded, you don't need a chef's edge here. -- EA trying to get the World's Sharpest Edge on one's lawn mower blade may just be a waste of time after the first 100 blades of grass get cut. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com Do you need to implement control loops in software?

My guess is it will take longer unless you got a nifty quick way to mount at an angle. Of course, I have a nice six inch bench grinder with a coarse stone. If you got a smaller grinder, the mill may come out faster. |

The wheel isn't quite as cool-cutting as a coarse wheel on a bench grinder, but it's so much easier to hold the right angle, and to see what you're doing, that the job goes much faster even though you have to let the blade cool after every few passes. Not that the stuff they make blades out of is likely to suffer from some overheating, but I just hate to see that blue color on steel while I'm grinding it.

If this isn't a good idea, then everyone should forget I asked a stupid question. Actually, it sounds brilliant! I once spent almost two days standing in front of the bench grinder making a blade from scratch out of a piece of spring steel, 3" x 1/4" (about the size of a mower blade). But I admit I'd be a little reluctant to cut spring steel on a mill; but ordinary A36 or even O1 should be a snap. And you could get that "hollow ground" effect by using the right size of ball end mill. :-) Have Fun! Rich |

As fast as they spin, the balancing is important, also. I've
seen mowers out of balance, it's not fun. I put a nail in the wall, leave an inch or so unpounded. Hang the blade on that. Side to side, like a bow tie. Let go.

Slightly off-thread:
I once had a 30" Gravely mower with a monster blade: about 3/8" thick by 3" wide & 30" long. As the end kept getting narrower and narrower from sharpening and I put off buying a new one ($$), it occurred to me that I could make it into a flail mower by cutting off the narrow ends and bolting on short flails. Those flails could even be pieces of 21" mower blades, which could be had for no cost (dump). I sold the mower before I had to do anything about the blade, but would the conversion-to-flail have been a good idea? Bob |

I think you would waste a lot of blade material by milling. The problem
that I have is that the tips of the blades wear away faster than the rest of the cutting surface. So one straight cut won't do it. I have 2 old Cub Cadets with 3 blades each to sharpen. I simply use an old 6" bench grinder. That way, I can sharpen the worn tip by following the worn edge by eye. BTW, if I am feeling particularly cheap, I heat the tip and forge material from the back side of the tip toward the front to give me an extra year or two of use--- just like they used to do to "sharpen" a plow share.

: I think you would waste a lot of blade material by milling. The problem that I have is that the tips of the blades wear away faster than the rest of the cutting surface. That's why the acceptable profile may include an angle from inside to tip. Yes, you remove more metal by milling than by "selective" grinding, but there are advantages. One: once it's jigged up the first time, it takes only two or three minutes to mill the ends, and the blades are usually spot-on for balance after. Two: A "hollow grind" was suggested here... that's wrong on a mower blade. When so done, the edge wears faster, and the "shoulder" at the back of the hollow erodes quickly if there's any sand in your mowing field. Three: It's what Oregon recommends for optimum cutting with their blades. I get roughly 30 acres per sharpening -- that's five mowings of the area I mow weekly. A blade lasts through about 10-15 sharpenings. So, I get more than a whole year's worth of mowing from one set of blades, and a new set of three is about $40. For me, at least, it's worth it to get that "golf course" look in the front of my property. I have three "working" sets used in rotation, so I don't have to stop for sharpening, if I decide they need it. It only takes five minutes to change a set of blades on the Scagg 61" deck. Except for dropping the blade bolts out of the spindle bores, it's all done from the top of the deck, with no removals or loosening of any other components. LLoyd |

There are days when I can't leave the windows open because of the more-or-less continuous noise and smell from the landscapers. 5 guys with leaf blowers and giant riding mowers to deal with a 50'x100' lot (with a house on it) is pretty excessive, but that's the norm around here. I mow my lawn in about 5 minutes, using a hand trimmer to get around the trees (another two minutes) and I'm done. People ask why there are more birds and butterflies in my yard than in theirs. They don't seem to understand the evils of monoculture (see Irish potato famine) and chemical herbicides and pesticides. One neighbor (across the street) just planted tomatoes in front of her house. Very nice, but they are in a garden bed that her landscaper poisons every week. Sheesh. She's also a couple of weeks early putting in the tomatoes - the nights still get pretty cool here, but she'll learn.

I'm just fine with that, quite frankly. Among the highest form of comedies is people who move to a desert and then spend money trying to grow a green lawn. Recreational farming is, I guess, fine. My vegetables would likely fall into that category as well - I don't really grow enough to make a significant dent in my food budget and the economics probably don't work out well, but I don't keep track of that money. However, if one is going to go to all the trouble of maintaining a lawn, why not put that effort into something that's useful? Lloyd flies model planes off his lawn, and that is (to me) the best reason to have any sort of lawn (I have to drive 5 miles to the local model airfield). But as far as something nice to look at? If I had property that large, I'd probably till the whole thing and scatter mixed wildflower seeds and let it run wild. Easy enough to mulch a few paths out to sitting areas to avoid having to wade through the brush. There are places in th US southwest that now have unbearably high pollen counts because of morons who moved there and brought their lawns and trees and flowers. The real (tragic) comedy is that many of these people moved there for the LOW pollen count. Just to muddy the topic a little more, this just came in my email: http://www.rdmag.com/News/2011/05/Ma...ce-for-rubber/ The “Russian dandelion,” Taraxacum kok-saghyz (TKS), is being domesticated at Ohio State University’s Ohio Agricultural Research and Development Center’s (OARDC) Wooster campus and produces high-quality natural rubber in its fleshy taproot. Its performance mirrors the natural rubber produced from Hevea brasiliensis (the Brazilian rubber tree). According to its developers, natural rubber provides performance characteristics not available from synthetic, petroleum- derived rubber for trucking, construction, and aviation tires. Natural rubber produced from Hevea is the only commodity volume source for tires and rubber industrial products in the world. Current shortage of supply has driven a six-fold price increase since 2002. Tests of TKS rubber produced in Wooster have found the material to be of comparable quality to Hevea rubber. An important additional product of TKS cultivation is ethanol. The project was announced by Ford on Tuesday, and company engineers are testing the substance to determine its durability. Initially, the research will focus on the substance’s potential use as a strengthener for impact plastics. “Managing weed problems is essential to developing TKS as a commercially viable domestic source of natural rubber in the U.S.,” said Bill Ravlin, associate director of OARDC. Ford could potentially use the substance as a plastics modifier, to help improve the impact strength of plastics. The material might then be used in places such as cupholders, floor mats and interior trim. Ford has previously used sustainable materials in its vehicles including soy foam seat cushions, wheat straw-filled plastic for interior trim and recycled cotton from blue jeans as sound-dampening material A collaboration including the Ohio State University, the University of Akron, Oregon State University, Cooper Tire and Bridgestone Americas received a $3 million Third Frontier Wright Projects Program grant through the Ohio Department of Development to develop a new industry based on this renewable, domestic source of natural rubber. Most of the funding was targeted to building a pilot-scale processing facility on OARDC’s Wooster campus that will generate 20 metric tons of rubber per year for industrial testing. “It’s strange to see weeds being grown in perfectly manicured rows in a greenhouse, but these dandelions could be the next sustainable material in our vehicles,” said Harris. Before the dandelion-derived rubber can be put to use, Ford researchers will assess the initial quality of the material to evaluate how it will perform in a variety of plastics that are used in vehicles and to ensure it meets durability standards. Besides the dandelion, the team also is looking into the use of guayule (a southwestern U.S. shrub) as a natural rubber, which is provided by OARDC and can also be grown domestically. |

Suburban people spend money on little machines and irrigation and chemicals to plant, raise and harvest a tiny crop--that they don't really do anything with. But they have fun with the challenge, and it keeps them in the suburbs where they belong. Eventually I plan to move to the US desert southwest, and my lawn is going to be rocks and dirt. I'm just fine with that, quite frankly. that's the way mine is. 0 maintenance. i just use pre-emergent or roundup on the gravel driveway. Among the highest form of comedies is people who move to a desert and then spend money trying to grow a green lawn. they sometimes just use green painted rocks. if you squint your eyes real hard, you can pretend it grass. in a couple of extreme cases, i've seen green painted concrete for the entire front lawn. regards, charlie phx, az |

I'm just fine with that, quite frankly. Among the highest form of comedies is people who move to a desert and then spend money trying to grow a green lawn. Recreational farming is, I guess, fine. My vegetables would likely fall into that category as well - I don't really grow enough to make a significant dent in my food budget and the economics probably don't work out well, but I don't keep track of that money. However, if one is going to go to all the trouble of maintaining a lawn, why not put that effort into something that's useful? Lloyd flies model planes off his lawn, and that is (to me) the best reason to have any sort of lawn (I have to drive 5 miles to the local model airfield). But as far as something nice to look at? If I had property that large, I'd probably till the whole thing and scatter mixed wildflower seeds and let it run wild. Easy enough to mulch a few paths out to sitting areas to avoid having to wade through the brush. There are places in th US southwest that now have unbearably high pollen counts because of morons who moved there and brought their lawns and trees and flowers. The real (tragic) comedy is that many of these people moved there for the LOW pollen count. olive and mulberry trees are the worst in this area, and were banned from being sold for quite a few years now. a lot of people pay a bunch every year to have existing trees sprayed so they don't produce pollen. regards, charlie phx, az |

My yard is nowhere near big enough for that sort of play, but we do have a paved- runway model field about five miles away. As for wading through the "weeds," it's easy enough to mulch (or mow) paths through a meadow. To each, I guess, his own. |

When it gets around to raining it greens up and when] it's dry its brown. Have to mow a few time a year when it's dry and maybe every 3 weeks or so when it's wet. :-) Front yard is some desert plants and some concrete product called "Tuff Turf" 18 x 24 inch blocks 4" tck with a hole pattern and filled with sand.

@newsfe17.iad: Maybe you could take a picture and post it next time you have it setup. Wayne D. I'll try to remember to. I have a sharpening coming up in a few weeks. We're in a drought right now, and I haven't had to mow in three weeks. LLoyd |

Wayne formulated the question :
My lawn mower blades get dinged up real good by sticks and small rocks. Grinding them takes me a long time, 2 blades, 4 edges. Is there any reason why I couldn't set up the angle in the mill and clean them up with an end mill? I would think this would be a lot faster. I could always grind in the final edge. If this isn't a good idea, then everyone should forget I asked a stupid question. Wayne D. I haven't pulled the lawnmower out yet. So I haven't given it a shot yet. Wayne D. |
