@@procalcosmx1142 Hello ! I think you would have to use a hexagon shaped block instead of the square one I used. Thanks for coming by. Cheers Neil

@@NellsMechanicalManCave ok parece buena idea voy a probar y te cuento gracias

@@Streetduck my email can be found at the end of my newest videos

Good call Victor! Sometimes you cant see the wood for the trees, as the saying goes 😊 Cheers Neil

Might be a good idea to watch the two other uploads. The third and last video with +50k views shows how it works. It's very simple and basic but works. Thanks for coming by and commenting. All the very best to you. 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

It works well 😊😊

Hi Steve and thanks for the kind comment. It was an out of the head idea and design. Works well but as others have mentioned, the ratio needs to be increased. Cheers Neil

Thanks for coming by! It was only done to make life easier for me. If it helps anyone else, it's a massive bonus 😊 Thanks so much for commenting. Cheers Neil

Hi there ! Sorry my friend but I don't work from drawings. I design everything in my head as I make each individual part. That's why sometimes things dont quite work. Think of this as a balance scale or a seesaw. There is more weight on the side that touches the cutting tool so it stays in contact because of gravity. The pointer is directly above the pivot hole and needs to be a minimum of 4 times longer that the distance from the pivot hole to the point where the cutting tool touches. This gives you a ratio of 4:1. That's it really. Make a small seesaw on the table and move the pivot point back and fore. You will see how it can effect the amount of travel. 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

@@NellsMechanicalManCave Oh, that's much better. Thanks for posting that.

It was only an idea floating around inside my head. If you read some of the comments, you will see that we all decided on a shorter arm that sits on the tool and a longer pointer. Greater ratio so more accurate. Thanks for coming by, Cheers Neil

Hi Bradley. No, I'm afraid I dont know the bearing numbers. It was 1942 and details are very limited. When I'm well enough, I'll take a trip to the workshop and pop a bearing out. I will look for numbers or identifying Mark's and post my findings. Cheers Neil

@@NellsMechanicalManCave Thanks Neil, I hope you feel better soon. If all goes well I'll be picking one of these beasts up tomorrow for about 150 pounds, seller says it just has to go and the headstock is a little wobbly, not sure about the bedways though. Is there anything you can tell me to look out for / test before I buy it? Thanks once again.

​@NellsMechanicalManCave Hi Niel, sorry for the second message but do you know where those axis wheels you have came from? I can see they're quite nice and have obvious divisions for somewhat accurate tool movement but the one I'm looking at has generic handles and no divisions? Thanks once again

That sounds like a great idea ! Cheers Neil 😊😊

Hi, Think I went for a 300 grit. I did a Google search and read a thread in practical machinist that said over 150 and below 500. Over 500 requires water cooling and 1200 gives a mirror finish. Cheers Neil

I did 😊😊 In one of the earlier videos of the build I gave credit to Harold and also Kev who introduced me to the great mans work. Cheers Neil

Hi Scotydog. Us taffy's are a rare breed on here. Been trying to get a 57 year old project (me) operational for the last months. I hope that all the failing bits will be sorted soon and I can get back in the shed and share some ideas. Cheers Neil 😊

@@NellsMechanicalManCave i hope so to mate 🙏🏻🙏🏻 wishing you good health for 2024

Hi Graham, It works well and is quite easy to make. Cheers Neil

I just watched your video on drill sharpening. I see how this block can be used for drill bits. Very clever idea you have 👍🏻👍🏻

If you look at the 2 other videos, it will show you all the parts and how the feeder works 😊😊😊

Sorry,, cant translate your comment 😕😕

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 😊

Mark !!! That's excellent.... So pleased that one of my ideas has helped someone. As you said, setting a new tool to height is unbelievably quick using this simple tool. Thanks for letting me know, you made my day 😊😊😊 Cheers Neil

Hi Grey, As stated,, increase the ratio between the arm and the indicator pointer. Other than that , it works great. Thanks fir coming by 😊 Cheers Neil!

Hi David. It works well but,,,,, The ratio between the arm and indicator needs to be greater and a real bearing used at the pivot point. When I get back in the workshop I will make these changes myself. Thanks for coming by and commenting, Cheers Neil

I'll look now for you.

Ty, I got it

Hi, The idea came from a book by Harold Hall and Mr Factotum ( Kev) did a few videos on the design. I don't know the exact name of the book but Kev mentions it so it's easy to look up. 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

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

@@NellsMechanicalManCave The engine speed is not for the diamond cup, but the speed for the cutter when it is in the robot

@@Сутьділа 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...

@@Сутьділа Small cuts at high revolution speed gives good surface finish. Coolant or light oil also helps with finish. Cheers Neil 😊😊

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

Hi. Sadly this is something that I can't help you with at the moment. I can't go into detail but I have been taken ill and it could be months before I get back in the workshop. I can do a drawing if you like which will allow you to make the parts and get it welded locally. Email me and I'll forward what I can. Cheers Neil

No problem Neil. Please get well soon! All the best, Adil

Hi again. Yes, these machines are available on Amazon UK at 220 to 240volts. Hope this helps. Thanks Neil

Hi Keith. Look at one of my more recent videos and the email is shown. Cheers Neil

Or, go to my majn page and click on "About"

@@NellsMechanicalManCave will do thank you

Hi, Yes the one I bought is 240v. I got it off Amazon UK

Yes it was. Got my sander from Amazon UK. It was the only type available here. I will be moving that switch off the top. Cheers Neil

Hj Mick! If you make one, keep the hammer arm short and the indicator needle long. The higher the ratio, the greater the accuracy. Good to hear from you, Cheers Neil
