Grinding Rest Part 1 for Bench Grinders to Sharpen End/Slot Mills (Modifications) "mr factotum"

[@steved8038]

Interesting project and as you say very useful to most hobbyist that don't need and can't justify the expense of a T&C grinder,looking forward to next part.Thank you.

[@MrFactotum]

thanks steve appreciate the feedback, see you on next part cheers Kev

[@AmateurRedneckWorkshop]

That is certainly a useful tool. Thanks for the video.

[@MrFactotum]

cheers Harold appreciate the feedback take care Kev UK

KISS. Looking forward to the mods, I like how you Sandwiched a slitting disc behind your white cup disc, I’m going to have to make a lot of space for all these wonderful ideas I see on these channels.

[@MrFactotum]

hi ian you need to build upwards🤣🤣🤣👍👍

[@MattysWorkshop]

Gday Kev, thanks very much for the shoutout, I’m glad the stickers have finally arrived, I like the general idea of the grinder setup, as you say it just needs some light changes, I’m looking forward to part 2, cheers

[@MrFactotum]

No problem 👍Matty take care Kev

[@KevinWoodsWorkshop]

Great idea Kev, anyway to help grind cutters can only be a good thing.

[@MrFactotum]

thanks Kevin yes, extends there life, saves money, it works well for me. thanks for the feedback, appreciated. Making the mods coming in part 2, how it fits to grinder and performs part 3, soon take care Kev

[@TheKnacklersWorkshop]

Hello Kev, I have been waiting for this series... I am a big fan of Harold Hall's work, he is/was an extremely clever engineer... I have just sent you an email with some links to more of his stuff... See you in part two. Take care. Paul,,

[@MrFactotum]

Hi Paul Yes, i have gathered he is a great engineer from reading the book i worked to, it saved me a lot of headaches 10 years ago, when i was in the process of starting to make my own design, so on finding the book i took the easier option, and i have used it ever since. thanks for the info i will take a look. take care Kev

[@tom_tom_go]

That revolving bench grinder table of yours is a great idea Keith!

[@MrFactotum]

cheers ttg thanks for feedback Kev

[@hullygully-3599]

Great. Thanks for taking time out to do this topic. Been waiting for it

[@MrFactotum]

hi HG thanks for feedback , modifications in part 2 soon, then fitting to grinder and demo in part 3 cheers Kev

[@andrewdolinskiatcarpathian]

Hi Kev. Great introduction to what promises to be an interesting series. Looking forward to seeing how your ideas develop and are accomplished. Good luck. 👏👏👍😀 Andrew

[@MrFactotum]

thanks Andrew all revealed in P2 mods & P3 Demo cheers Kev

[@retromechanicalengineer]

Really nicely made kit, Kev. I need to find room for a bench grinder, your carousel idea is genius! Best wishes, Dean.

[@MrFactotum]

hi Dean thanks for the feedback, its appreciated, it's a great system where budget and space is premium. part 2 soon for the making the mods, part 3 for a Demo cheers take care Kev

[@RetroSteamTech]

Hi Kev. Very interesting, I like simple ideas and that cutter grinding adaptor is great. From what you have said your mods should make using the thing much easier. Cheers, Alan.

[@MrFactotum]

eyup Alan Thanks for feedback , appreciated cheers Kev

[@houseofbrokendobbsthings5537]

Thanks Kev. That’s the book I have as well. Looking forward to see how you get along. All the best Dan

[@MrFactotum]

thanks Dan, great book, it works well for me, modifications in part 2, and fitting to grinder and in use in Part 3, soon take care Kev

[@MyHeap]

Hi Kev. I know I am a bit late commenting on this video. I have that book by Harold Hall too and it was a great read. I have purchased all the bits to make the grinding rest in the book and just recently got the ball fro the joint. I got 1 inch nylon plastic balls. I hope that works. My offhand grinding skills can use all they help I can get. I am hoping this will be one of my projects to do when I get back in the shop. Which, by the way, I hope to be soon. I think I am done with the remodeling for a while and now that the hospital is well on it way with the transition to the new owners, I hope to have more time for personal stuff. Thanks for sharing. Joe

[@MrFactotum]

Hi Joe Nice to hear from you, yes it's a great book from a great engineer, but i just had to do the modifications that were irritating me, glad to hear your going to have time for yourself, life's too short!!!! so make time!!!!! See you soon then Cheers Kev

[@NellsMechanicalManCave]

Good to see you back on your feet Kev 😊 Been looking forward to this for a while. Do me a favour! Take the adjustable stop apart so I can see how you made it. It would work great on my diamond sharpener I think. Cheers Neil

[@MrFactotum]

Hi Neil. Thanks for your usual support, full details are in the next video, then how it operates / in use in the video after that, but if you want me to photograph the drawings and email them to you before the big video release🤣 thats no problem at all. cheers Kev

[@NellsMechanicalManCave]

@@MrFactotum Kev, if you have time for the photo, that would be great !!!!!

[@MrFactotum]

@@NellsMechanicalManCave Hi Neil I think i have emailed them in 4 emails to you, as a link may be, if you don't recieve them i will photo later and re email, when i'm back home cheers Kev

[@NellsMechanicalManCave]

@@MrFactotum I think it's a link on your pc so I can't open them unless I'm sat at your computer drinking tea with you 😁 No worries mate, cheers Neil

[@MrFactotum]

@@NellsMechanicalManCave Ok Neil this techno dinosaur is on to it, bear with me. cheers Kev

[@kimber1958]

Looks like another project for me I’ve been needing something like that ever since I got the grinder

[@MrFactotum]

hi kz. you need a good project to get your teeth in to, now "big grey" is sorted, thanks for the feedback Kev

[@jonsworkshop]

Hi Kev, interesting video, looking forward to seeing it in bits and then with the mods etc. All your planned mods are well thought out and will make a big difference to the ease of setting. I need something like this but I think I am going to look into the blocks you can get for use with the surface grinder. Cheers, Jon

[@MrFactotum]

cheers jon It's only took me 10 year to modify it!!!🤣🤣👍👍 yes if you have a surface grinder, make use of it, take care Kev

[@MattChiversWorkshop]

Interesting idea… a)think I’ll go hunt that book down as I have many milling cutters that need attention, b) I have a spare bench grinder not doing anything. All the best, Matt 👍

[@MrFactotum]

cheers Matt, go for it and get grinding!!!🙌 regards Kev

[@rjordans]

Make sure to have a look at Harold Hall's website. Het has pictures and drawings online for a lot of the projects in his books

[@MrFactotum]

@@rjordans Hi Roel Thanks, yes i've been told by a couple of people, but thanks for belt and bracing it for me, appreciate the feedback, hope all's well at your end. take care Kev

[@Jims-Workshop]

Kev, I will be looking for part 2. I have a T&C grinder with an endmill attachment, however this looks far more usable for the quick and easy touch up on the Primary and Secondary angles. Your modifications to improve the useability even more sound like a good idea.

[@MrFactotum]

Cheers Jim Not be long for part 2 then part 3 it will all become clearer then. and it's now simple to use with the mods. Also your sticker will be going up on the board soon. take care Kev

[@BensWorkshop]

Whilst I do not have that book, I do have Harold Hall's book on using the mill which has a different design for a grinding adaptor though you would need a mill to make it and it has dovetails. Good work, looking forward to seeing what you come up with.

[@MrFactotum]

cheers Ben all to be revealed soon. take care Kev

[@FWSwart999]

Hi Kev, Been following your channel for a while now. I have had the grinding rest project on my list for some time now so will be following this to see the improvements you have planned. I have collected most of the books in the series and the ones by Harold Hall seem to be the best written (in my opinion). Mr Hall has these drawings (and others for lots of projects) on his website with detailed instructions and photos. Keep well, Francois

[@MrFactotum]

Hi Francois Nice to hear you've been following me, it's appreciated, yes the workshop series books are great, Hope you get the grinding rest made, it works well for me, next video showing making my modifications, then the one after will be showing how to set it up and how it performs. see you next time take care Kev

[@chrisbangemann1792]

Hi I’m Chris I’m new to machining and found your video on making your grinder rest very helpful I was wondering where I could find drawings plans for your simplified tool sharpening tool rest Thank you for the great information you share

[@MrFactotum]

eyup Chris nice to hear your learning machining. the plans are not mine, i just did some user friendly modifications to the grinder rest. The plans are freely available on the internet from Workshop Practice Series 38 (loose plans) simple grinding rest, designed by harold hall. There are a few different ones that are more involved to make but they are all there free to use. As for my modifications i have no plans but i think my videos will give you all the info, required. Any questions at any time feel free to ask my "Grey Cells" Thanks for watching and for the feedback regards Kev

[@chrisbangemann1792]

Thank you for being so helpful Please continue to help others like me Best wishes

[@SteamerEdge]

Hi Kev, I'm following this with keen interest. I wondered what measuring tools you use to set up your grinding jig when changing for the required angles for sharpening different milling cutters or Drill bits ? Maybe you will show us at the end of the series.Thanks for videos Paul

[@MrFactotum]

Hi Paul thanks for your interest. I have not used it for drill bits, but i'm sure in the book there is a method, but for end mills and slot mills, If you make all the parts accuratly to the drawing, (part 2 for that) on a 6" (150 dia. wheel ), set it acurately to the bench grinder initially (Part 3 ), thats it, the primary and secondary angle fall in to place automatically each time they are moved from one to the other, if you want the drawings before part 2 (shown next week), i can email them to you. Check out my about page and my email is on it, then email me if you would like the drawings, it's no problem at all take care Kev

[@SteamerEdge]

@@MrFactotum Thanks Kev, much appreciated, will send an email

[@paulmorrey4298]

Thanks

cheers Paul appreciate the feedback👍👍 atb Kev

[@amcbi05]

Great videos series Kevin. I just received the Tool and Cutter Sharpening book by Harold Hall but it did not include the plans for the simple version that you show in this video series. Do you know where I can get those plans?

[@MrFactotum]

thank you amcbi appreciate the feedback, Good to hear your having a go at the endmill sharpener. Yes, when i acquired the book 2nd hand i think the plans were on loose folded a4 sheets, so somone must have included them Harold Hall has a free website with loads of different projects, try this www.homews.co.uk/page121.html and it should take you to them. If not send me your email and i will get a copy to you. Hope you include my modifications to it as you will find it helps the ease of use kzbin.info/www/bejne/iniyaZumbdtjoc0 good luck and let me know how you get on with it ATB Kev

[@ianbertenshaw4350]

The biggest problem with this style of sharpener is that any lift of the cutter being ground above the centre line of the wheel changes the angle of contact and the angle of the resulting ground surface - they work better with a cup wheel where the cutting surface is flat . An easier way is to set up the rest so the centre line of the tool holder ( the piece you clamp the cutter in) bore is level with the centre line of the grinder spindle and then use a spacer under the tool holder to raise it up a pre determined amount ( a cad programme makes determining this easy ) to give the correct cutting angles - it may be something like 10 mm for the primary and 25 mm for the secondary , maybe more , maybe less ,

[@MrFactotum]

Hi Ian Yes, you have to adhere to the correct dimensions when making this rest with the position of the arm and table holes, and combined with 25 mm square stock for the cutter holder it then always ends up on the centre line automatically, all will become clearer in next video. Its worked for me for the last 10 years. thanks for the feedback and watching appreciated Kev

[@davej3487]

I am wondering if these blocks could be made to hold a common R8 collet. This way you would not need to make 10 different sizes of inserts to fit the 3/4 inch hole. Maybe use 40mm square stock Just take your 3/8's R8 collet and 3/8's end mill, put in the square holder and lock it true to the table. The square holder should be long enough for a cap screw in the back to crank the R8 collet back into the hole, locking the end mill tight. The square holders round hole would not need to be tapered for the R8, just pulling it into the holder will squeeze the collet down on the end mill.

[@MrFactotum]

eyup Dave. I've skimmed over your comment without putting the detailed thought in to it, due to my time contraints, and i'm sure there are many possibilities to modify it to suit your needs, just like i modified the original concept. However just off top of my head i think if you use a larger block from the 1" square, it will change all the angle relationship with the grinding wheel and grinding rest to the cutter and therefore the cutter angles may be changed. Just a thought, to play around with. Let me know what you come up with, as i'm interested, my brain can't multi task anymore🤣🤣and i'm fully immersed in another project at the moment. keep in touch BFN Kev

[@mercerengland3392]

Hello Kev, I’ve watched most of your videos which are brilliant. With the cutter grinder in mind, are the plans for making the simplified versions or your modified version available? I’d truly appreciate a copy?

[@MrFactotum]

Yes, absolutely me3392 thanks for the feedback, all the drawings by Harold Hall are freely available. the one you want should be in this link, just copy it then paste in your search bar homews.co.uk/page121.html then just apply my modifications to the original if you want to make it more user friendly, there is also a more involved grinding rest, just look around Harold Halls projects Index page. regards Kev
