DIY LAWN MOWER BLADE SHARPENER "THE BUM-BEE"-Detailed Drawings

[@robertskerke4855]

Thank you for this bum-bee. I am so glad they’re are people like you in the world who share their talents with the rest of us. Thank you again. Robert 👍🇦🇺🙃

[@BumBee22]

You're welcome.

[@BumBee22]

You're welcome and thank you

[@farisal-salihi3780]

Thank you for the innovative design. This is exactly what I needed.

[@BumBee22]

You're welcome, have fun with your build.

[@DanneyOgle]

Wanted to add my Thank you to the author of this video. I've been looking for a simple but reliable lawnmower blade sharpening fixture that I could use my hand grinder with and this certainly fit the bill. The horizontal design was exactly what i was looking for so I could easily access the grinder's on/off switch as well as keep everything in a low profile for storage. I proceeded to build the part that supports the grinder first so I could make any height and width modifications as needed for my brand of grinder. I then built the 30-degree angle section that supports the blade with a little large base so I could adjust it to fit exactly on the centerline of my particular grinding disk. My only addition was a 1.5" thick board in the rear to give me a solid place to put a 6" clamp to hold fixture this to my worktable. Finished the whole fixture in less than 90 min with your helpful photos and prints. Came out great. Finished sharpening my (4) lawnmower blades in no time. Nice Work!

[@BumBee22]

Fantastic, the author of this video is me, BumBee22....LOL By the way, what brand of grinder did you use?

[@DanneyOgle]

@@BumBee22 I mounted my vintage but reliable 12-yr old Ryobi hand grinder to your Sharpening fixture I made. The handle holes on my Ryobi are drilled at an angle which required a little finesse to drill the bolt hole to secure the front of the grinder at a level position but manageable. I positioned the blade back support about 1/16" from the face of a 4-1/2" dia. 60-grit grinding flap disc.

[@BumBee22]

Awesome, I'm glad this worked for you.

[@Nous3rnam3haha]

Works perfectly and saved me a minimum $300! For anyone else trying/thinking about making one, realize every grinder is different in shape and size but are relatively close in design. These drawings will get you into the ballpark but be expecting to fine tune the stand to your grinder the best you can to fit these designs. Thank you for these designs BumBee22!

[@BumBee22]

You're Welcome! I am glad this worked out good for you.

[@jedivlix]

Awesome! Had to do a few minor mods for my grinder. Amazing results on my blades. Anyone who wants to do this, it is worth it! Thank you for the design!

[@BumBee22]

I'm glad, you're welcome.

[@robojim5585]

Great video nice drawing

[@BumBee22]

Thank you very much.

[@Doodad2]

Thank You! It doesn't get any better than this! Excellent drawings BTW, I'm a retired machinist and have had to work off of some really old and crappy drawings. Good job on all accounts!

[@BumBee22]

Good to hear from someone from my old world. Made drawings manually at the start then onto CADD systems. I am retired as well. As a new owner of a twin blade riding lawn mower, I looked into buying a Lawn Mower Blade Sharpener. The ones I saw on the market were too complicated, bulky and expensive. Here we are, glad to share what I came up with.

[@scarey2me]

That is brilliant. Thank you.

[@riverbottomband]

Thanks and you earned a subscriber because you don't try to sell me anything but give it away free. Thanks a bunch.

[@BumBee22]

You may wanna go look at my lawn mower blade sharpeners videos. You might find something simple and easy to make. It will do the job just as good as this one without having to adjust this and that.

[@xptwinksxp4086]

YAAAASSS!! IM GONNA GO MAKE THIS RIGHT. NOW. NO more free hand🥲👏👏👏

[@BumBee22]

Awesome! Which one are you gonna make?

[@hc7190]

I just finished building mine with a couple of necessary changes . First off my grinder when bolted down didn't lie perfectly flat and I couldn't find a flap wheel that was flat either . So I changed the angle of the cut so I could get the 30 degrees that I needed and it works just fine . I needed to buy the grinding wheel , other than that it was for free as I had the material needed for the build . Thanks for a great idea and sharing .

[@BumBee22]

You're welcome. I am glad you made it work for you. I suppose you used a different brand grander?

[@hc7190]

@@BumBee22 Yes it was a cheap harbor freight grinder but it works just fine for what I am using it for . I did some blades today and couldn't believe how sharp they came out .

[@BumBee22]

What did you do to stop the grinder from rotating on the 5/16 mounting bolt?

[@hc7190]

@@BumBee22 I found a metric bolt at tractor supply that fit my grinder but when tightened down it didn't lie flat so that is why I had to make an adjustment to the angles . To keep the grinder from turning I put two wooden stops at the end of the handle . I have an old toro wheel horse mower also and the angles for that were way different than for the xmart . I made a set up for that too and use the same base . Works Great

[@georgebenevides]

@@hc7190 People are saying the blades are not suppose to be sharp like a knife cuz the blade get dull faster. I know when I brought my blades to a dealer, the blades didn't come sharp. Enough to cut the grass well though. Has anyone tried sharp blades and sharp blades using a file but not very sharp. Any differences as to how long the blades stay sharp.

[@hc7190]

Great work and thanks for the drawings .

Thank you, Thank you very much, ah-huh-huh.

[@nerraw117]

I know it has been awhile so I am hoping you will share the updated drawings of the 4-5/5-5 version? I LOVE that setup. I know your worried about liability and I can sign a waiver.

[@BumBee22]

I just updated my ancient computers and I do not have the 3D software in it. You'll have to get the piece part dimensions from this video. You either take screen shots (use snipping tool) or make sketches. With the new 32" monitor, I can see the dimensions on the drawings clearly.

[@nerraw117]

@@BumBee22 i see the dimension drawings for the horizontal model but not the updated version that you used to sharpen the machete also. Thats an awesome design

[@gregphillips6699]

Excellent jigs! I would love to have a printable snapshot of your blue print with the vertical mount. Do you think that is possible? Personal home use only. I’m tired off free-handing with grinder. I almost always lose the correct angle. Thank you.

[@BumBee22]

You'll have to freeze frame and use the snipping tool to capture the image, then print it, or freeze frame and make sketches. or, here is a shortcut: %windir%\system32\SnippingTool.exe Copy and paste to your pc screen and execute it. I use this a lot.

[@gregphillips6699]

@@BumBee22 Got it! Thank you so much for this info…👌. I will only refer others to your KZbin site if questions about your product arise…

[@markward38]

Your timber work and drawings are brilliant. I’m going to try and build this ,but I don’t know if I will be able to replicate such great timber work

[@BumBee22]

I used 3/4-inch-thick plywood.

[@FastEddieQ]

Any way you can disarm and give specific dimensions🤔🤔🤔🤔 your diagram shows everything but not sure what is what😁

[@dennisdavila1045]

Thank you, excellent drawings, just what i needed. I just started sharpening my own blades and doing it free hand is not easy to keep the 30 degree angle. Can you tell me which brand of grinding disk are you using, the Harbor Freight ones that i bought have an angle, they are not flat. Thank you again for sharing your invention.

[@BumBee22]

Look for TYPE 27 grinding disc. This will have the flat grinding surface in all brands.

[@dennisdavila1045]

@@BumBee22 Thank you, that's the ticket. If anyone is going to use the Harbor Freight Bauer 8 amp grinder, the bolt is metric, M8-1.25x35

[@pismo_beach_life1780]

that is pretty

[@BumBee22]

Pretty is good thang...

[@tonywang4286]

Thank you for posting the video. What grit do you use on your flap disc?

[@BumBee22]

I use a 60 grit. A 40 grit will take more metal in one pass then the 60 or 80 grit.

[@FastEddieQ]

Thanks

[@ShaunTarves]

For those of us making to fit a different grinder, it would be helpful to know the finished distance from the flap pad to the chamfer on the bench piece.

[@BumBee22]

1.Use a Flap Pad that has a flat grinding surface. A T27 2.Make this that the Flap Pad is not grinding the Blade support piece. 3. You have to make adjustments so the grinder you're using will work.

[@randyplotts2435]

Would you sell one of these? I’m not that handy with things like this

[@BumBee22]

Nope, just sharing my design.

[@richardp948]

Nice

[@BumBee22]

Thank you

[@joeszymanski6936]

Great jig. Why do you have two different positions for the grinder.

[@BumBee22]

This allows whom ever decides to make one, they will have a choice of horizontally mounted grinder or a vertically mounted grinder using the same base.

[@hc7190]

Looking at the design further the only thing that worries me is the wheel pulling the blade down and jamming it between the jig and wheel and possibly throwing up the other end . I do realize there is very little space for it to be able to do that . Have you ever experienced that feeling while sharpening your blades ?

[@BumBee22]

No, and I have not heard of anyone have the experience you mentioned. I don't think it will get jammed unless the blade is intentionally jammed in. I think it will just stop the disc from turning.

[@hc7190]

@@BumBee22 That is good to hear as I am in the process of making one .

[@hc7190]

After building and using your design it works perfectly and no pull at all to the downside that I can tell .

[@Russell731]

In your opinion, of all the sharpening jigs you’ve made and put on KZbin, which one worked the best getting the blades sharp?

[@BumBee22]

I have not paid much attention to them lately. I could not tell you which one does the best job sharpening those blades.

Just sharing my idea on how to make a Lawn Mower Blade Sharpener.

[@kodak_jack]

You showed the first drawing as an overall drawing and we can stop and make a screen shot. After that, you're constantly moving around the other drawings and that can't be done. Do you have drawings available to download or for sale? If any of the viewers who were successful can make them available. it would help. Thanks.

[@BumBee22]

No drawings available, download or print. If you have Windows operating your computer, there is an app; "Snipping Tool". find this and learn how to use it.

[@mdlanor5414]

You have to the by far have the best and appears the easiest to fabricate a Lawn Mower Blade Sharpening Jig that uses a angle grinder (Blueprints /Schematics for measurements.) I’m asking for your permission to use your blueprints/schematic in this video? To make my own lawn mower blade sharpening jig?I will never duplicate your Blueprints/Schematics and or try to sell copies or make any videos and play them on any social platforms. I would like to use the blueprint/schematic that is in this video for a one time only private use for myself. I’ve over 20 blades for my riding lawnmower that are dull but not worn out. I want to be able to sharpen them properly. Your Angle Grinder Lawn Mower Sharpening Jig. Is just what I need. I do know to use a flap disc on one of my angle grinders and i always wear safety glasses , gloves and a mask whenever I’m grinding anything.

[@BumBee22]

Thank you for asking. Yes, you have my permission to make your personal use Lawn Mower Blade Sharpener.

[@mdlanor5414]

@@BumBee22 👍

[@PGSTARR]

I wish you would scan your drawings and attach them as a PDF we could download. I'd even pay you for them.

[@BumBee22]

That is a good suggestion, thank you. In the main time, FREEZE SCREEN and you'll have to make sketches to make this jig.

[@joecnc3341]

Full- screen - Pause the video - use the snipping tool to copy and paste the screen into Word or WordPad. I took the measurements off the screen and modeled it in Fusion 360.. drawings are next.

[@BumBee22]

Excellent, I use the snipping tool too.

[@edmorie6032]

How do I get a drawing

[@BumBee22]

You have to use the "SNIPPING APP (free)" screen shots of the drawing I show here in my video. Save them to a file and then print them. If you have windows 10, it's in your computer already.

[@acts16.31saves]

I would like to purchase these

[@BumBee22]

I don't sell them or the drawings. You have to make it yourself. Use the SNIPPING tool to capture images of the drawing.

[@Stratman48]

how much plywood do i need to buy to make the horizontal one...

[@BumBee22]

Cut three 3"x8", cut two 2"x1-1/2" cut two 1-1/2'x8" and cut two 3"x5-1/8'

BTW - Very Nice job on your prints. You must be a designer, engineer, or machinist. What CAD software did you use?

[@BumBee22]

Started out as a Draftsman (manual) then to CADD systems. Mech Designer, Pro-e Creo 5.0

[@opichocal]

Never seen that before. I’ve been cutting grass for 35 years now and just step on the blade over a bucket and use a 4.5” grinder. I bet I have sharpened 10000 blades that way and never balanced a single one.

[@BumBee22]

Awesome!

[@kicko61]

ALWAYS un plug grinder BEFORE changing discs

[@joecnc3341]

What grit of Flap Disk are you running? 120? 60?

[@BumBee22]

40, 60 or 80 grit will do. I prefer the 60 grit for it usually does the job with one pass.

Do you sell these? I have no wood working equipment to build one. Thanks 👍
