@@gm-lb9oe hi. I got the wheel off ebay. It was about £30. Can't remember what grit it was, think it was 200. I did a Google search and on there it gave diamond grits and what they are best used for. Cheers Neil
Thank you for sharing your design. It looks like a nice and simple solution for sharpening. It should also be useful for re-sharpening drill bits. I really like the alignment shelf. One change I would suggest is to use a collet block.
Thanks Wiz Rom ! It's not my idea, but I have modified it to simplify the design. If everyone shared ideas which is my way, everyone would be some much more prosperous 😊 Thanks for coming by. Best regards Neil
Gday, brilliant idea machining the shelf in to pick up centre height, I really like this setup, simple and effective, thanks very much for sharing mate, cheers
Hi Joel ! What would make me pleased is this little 6 minute video makes life easier and more affordable to people like us 😊 With an almost zero budget I've managed to make something that could save 100s over time to anyone who copies it. I sincerely hope I've explained it well enough that anyone can follow. If one person benefits then I've achieved my goal😊 What can be more fulfilling than making someone's life easier. Thank you so much. Neil
It will never beat a properly sharpened or new end mill, but it saves a shed load of money replacing slightly blunted or chipped tools. Thanks for coming by, Cheers Neil
Well done buddy, a very nice conclusion to a worthwhile project. Next time I come round I will bring the first installment of all the end mills I need you to sharpen 😁😁
Morning Neil. 👏👏👏. You brought the plans from Kev to life - brilliantly. Your subtle tweaks likewise make this tool very easy to work with. As far as the little black dot - I see a real-time lubrication port. 😏 Now how do I send 75lbs of dull end mills to your door in an inexpensive manner? LOL. To quote Marty Feldman in the movie “Young Frankenstein” “he’s going to be quite popular” meaning I predict new friends dropping by with a bags of banged up end mills. LOL. Well done - you should feel very proud of what you completed. All the best Dan
Thank you Dan ! Come to the UK on vacation. Put the end Mills in your socks! Remember The Great Escape movie 😁😁😁 Also, if anyone wants to come by, they would be made more than welcome! Cheers matey, Neil 👍🏻👍🏻
eyup Neil Some nice little extra touches added there, to my little extra touches, to Mr H.H's. great little T&C sharpener, thanks for the shout out. see you next time take care Kev
Wouldn't of happened if it wasn't for you! All credit goes your way !!! Mr. H,H may have created it. You modified it. I turned it into mutant 😳😳😳 Thanks Kev, you've inspired me again 👍🏻👍🏻👍🏻👍🏻 Cheers Neil
Hi. Wish I could say that it was my idea, but it's not 😊 But, it is a great idea which was well worth sharing with everyone. Thanks for stopping by, Cheers Neil
Hi Neil. Beautifully engineered and a great solution. Makes my Chinese Deckel SO clone look clumsy in comparison. Getting the endmills parallel on the Deckel clone is a hit or miss nightmare. Your “shelf” is a godsend. Can I think of a solution for my machine? 🤔 Thank you for sharing. 👏👏👍😀 Andrew
Andrew, you are a very resourceful man! I planted a seed and I know your brain cogs will be turning. Thank you for such nice a comment, I just like making life easier, imagination take very little energy! So, I think I'm lazy by design 😁 All the very best, Neil
Fantastic job. Is there a way to gage the angle of the face cut for the primary and secondary facets or is that a trial-and-error process? I'm thinking it is accomplished by the height or slope of the base plate on the jig.
Hi Jasper! Yes you are correct. You change the angle on the table for the clearance angle. If you go to Kev ( Mr Factotum's Workshop) there are a few videos there explaining how the table angle works in relation to a 6" grinding wheel for both cutting and clearance. The idea started with Harrold Hall. A quick Google search will find this genius 😊 Thanks for stopping by, not been uploading much recently but will once my mobility improves. Cheers Neil 👍🏻👍🏻👍🏻
Great little sharpener you've made there Neil. I need to sort something like that out for my workshop. Not sure if you noticed, but there's a little black dot on the top of your otherwise beautifully made thumbscrew! 😜
I had this funny feeling that it was going to be you 🤣🤣 Watch this space ! In construction there's a saying. "Always make a feature out of a f#@k up" I have a cunning plan 😏😏 Cheers Neil
Thanks Ken. It's a great project and money saver. I'm not a machinist and have less than 100 hours running the mill or lathe so technically I'm a novice too 😊. Most of what I do are tricks and tips off other RU-vid channels, Joe Pie is my go to for most things. Great to hear from you. All the best, Neil..
I bought a ftv-3 mill and a microtor d360 lathe...to push me forward..am a studying gunsmith...thought it would make life easier....lol.. now have less time for actual work... and more time to study new toys.. it is a strong learning curve... I studied at university 30 years back .. never used one since... bun now old...er....... have more patience ... take no prisoners... you can learn faster as you get older I found...the possibilities are endless..
Abom79... mrpete2222.. and many more.. .Tony.. .. but british vids I like more.... Mr Crispin, a brit who makes some informative vids..he's cool..., in a language I understand too... Support our own too is important..
@@kenjohnson6338 Mr. Crispin 😊 Hes mad as a box of frogs 🤣 but the guy is a genius! I used to watch Tony but he went CNC and away from us common folk in little workshops. I couldn't learn anything much off him then. There are many out there who are great though. Getting materials to work with is hard here. Ally and steel has tripled in price. I used to make heavy duty bipods but I cant afford the materials now.
Looks great! How is your power feed holding up? I already have all the parts but no time during the semester to build it... Just out of curiosity: How important is the alignment of the cutting faces with the shelf? Because if you align them with a broken/dull face the angle does not match 100% and by grinding deeper into the endmill, the cutting face will not be at 90° anymore because of the helix. I am sure that it is negligible in this application and your cutters work great. But i am wondering how professional grinds are achieved and how companies would compensate for it. Jonas
Jonas, good to hear from you ! Firstly, now I have installed the relays to cut the power to the magnet, the drive works without any fault. I'm sure the auxiliary fan is helping but under normal conditions, it's not required. My mill has a 3mm pitch lead screw and it would be more suitable to fit a motor with a 30rpm output. You do the math 👍🏻 Second point. Set up the best visible face on the shelf. If you noticed in the video I picked the wrong one. The second cutting face I tried made contact not the one I set. Its a little trial and error at first. After an initial cut you can do a reset and cut again. This is no way a $2000 sharpening machine, it's a $50 modified bench grinder that will give you cutting tools that work again and if we talk cheap cutting tools, better than new. Cheap tools use pretty good materials, the sharpening and finishing are the problem. Usually they are seconds or substandard. A quick trim can give them a new life at a fraction of the cost. If you are stuck with anything, email your number and if needed we can talk on WhatsApp. A willing to help out anyone if I can. All the best Neil
@@NellsMechanicalManCave I agree, a reset and second cut with a minimal depth will improve the angle. For 50$ you have build an awesome tool, with current prices for decent endmills you only have to sharpen a few to make profit! Currently i am planning to build the power feed without any fan. The most difficult part is to find a way of transfering the torque as there is no keyway in the lead screw. Also fitting everything onto the small stub shaft requires some more planning. Thank you for the update!
Usually one try's not to use a high speed diamond wheel on HSS cutters, the diamond abrasive will oxidize with the heat. Diamond lasts a good time on a slow speed grinder...
Hi Larry, that's very true. Luckily in this application no heat is generated. The contact area is very small and only kisses the the diamond wheel to produce a sharpened edge. It would be no good at all if used to try and form a tool. If I do a follow up video, I will point this out. Thank for reminding me and pointing this out. Cheers Neil
Hi Neil, not sure how we have missed each other (apologies if you have been to my channel, I can't remember what I had for breakfast most days now🤔). Just subbed etc, great job on the end mill grinder. Cheers, Jon
Hi Jon, I have watched videos of yours and liked but I didnt subscribe (I have now though). The problem with suggested videos is, you dont know how or why they are suggested. If there was a link to Olly, I would have tapped the sub button because we have common interests other than Olly, of course. Great little community we have going, I'm not a machinist so never show that side of things, but I'm full of ideas suited to people who wish to make life easier. Cheers Neil
@@NellsMechanicalManCave Thanks Neil, I am (or was 25 yrs ago) a machinist, you would wonder at it sometimes mind! Spent the last 3 years re-learning old skills, and try to pass on as much as I remember with a blend of modern industrial experience where appropriate to help the home gamers out if I can. Cheers, Jon
@@jonsworkshop ah ! First time I drove a lathe was at 2am in the morning during a breakdown in the steelworks. Nobody there to do the job, so I used a bit of intelligence and a lot of luck😊 Still getting my head around precision engineering. Perhaps precision is the wrong word, close engineering is better😊. As I said I only offer ideas, I'm a very " Out of the Box" type person and once I've proven a concept I get bored and look for something else to solve or make easier. Off to look for your email if its posted. Need to solidify our subscriptions if that's ok with you! Cheers Neil 👍
Hj. I got my wheel from a company in the UK called RDG Tools. Their Web address is www.rdgtools.co.uk Go to the search on the site and look up flat diamond grinding wheel. They are on Ebay too. Sorry I can't do a link, I tried and failed Cheers Neil
The only problem with that end mill sharpener is that.... It's in the wrong garage. I want one. I have quite a few mills with damaged teeth. That would be perfect. Thanks for the great video. Regards. Steve.
Good afternoon. We protect ourselves from dust with surgical, disposable masks. And when we sharpen our incisors, we also wear them. A colleague wanted to ask you at what engine speeds do you process metal with these cutters?
Hi. This bench grinder runs at 2800rpm. I was careful to buy a diamond wheel that had a higher maximum speed. To my best recollection the wheel is rated at 3500rpm. Thanks Neil
@@user-yd7mp1py2x there are charts on the Internet to show rotation speed of the cutter and also travel over the cutting surface. A lot depends on the size of cutter and also the material being machined. I am not a machinist and mostly guess
@@NellsMechanicalManCave The cutter is 16 mm, the metal is regular black steel, grade 3, and steel 45 is not hardened. Manual feed is slow. And another question, the smaller the cut, the higher the speed? Thank you, I'm just starting to master the router...
@@mughalsons2254 to be honest, these diamond wheels are designed to sharpen and Horning cutting tools not shaping or grinding. There is quite a bit out there on the Web advising not to use them to grind as they can break up! There are circular saw blades available that will cut steel. Perhaps this might work. Again though, I have not tried this and research would be advised. Chars Neil
Found the translate now. Yes you can sharpen 5 cutting faces. You would need to machine a 5 sided block (pentagon) to hold the cutting tool though. Same goes for a 3 flute cutter. Cheers Neil 😊
Sorry to hear that. I bought from a company in the uk called RDG. They do mail order and sell on ebay. Prices have gone up but are still under $50. Look on Ebay you might get lucky. Cheers Neil
Try this link, $50 on ebay www.ebay.co.uk/itm/265256180553?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=m1PNtpB0Tsi&sssrc=4429486&ssuid=12o7hixpRZS&var=&widget_ver=artemis&media=COPY
Sorry, can't find a way to translate and sadly I'm not that clever enough to speak or read any other language. Britain isn't that great in all honesty. Many thanks Neil 😊
Sorry Eddie, Didn't see your comment. I think it's a very basic tool but can save money in a small shop. Things are very expensive at the moment and any saving means spare money for other items. Hopefully things will get easier and I can buy materials again soon 😊 Thanks Neil
