Nice work. We shared this video on our homemade tool forum last week 😎

Thanks for your comment,glad you are sharing,hope it is usefull to others,thanks for watching the video.

[@RustyInventions-wz6ir]

Interesting. Very nice work.

Thank you for your comment and thanks for watching the video.

Great video Harold,I like this method and will try it out tomorrow.

[@popperkeg1234]

Thanks for watching the video,yes give it a try I think you will find it ok,just be carefull moving the tooth rest though.

[@lexdavis2179]

@@popperkeg1234 One thing that I am not sure about is how to dress the side of the wheel that does the relieving, should it be dished in or flat?

[@popperkeg1234]

What you need to do is dress the side of the wheel so it is slightly hollow,not much but you need to make sure the edge is reasonably sharp,it will grind like a cup wheel,hope this will be of use.

Hello from Aus. Well acted instructions and video production. Keep up your work. BC

Thank you for the the nice comment and thank you for watching the video,all the best for the new year to you all down under and have a happy Xmas

[@FredAmnit]

My grandfather was a tool and die maker and I often wish I'd followed in his footsteps. Alas, now I can only watch and admire. Beautiful work sir! Thank you.

[@popperkeg1234]

Thank you for your nice comment and thank you for watching the video.

[@RoyShillinglaw]

I thought i was the only person doing this... Thanks for sharing this cutting tools are expensive bieng self reliant like this can save soooo... much time and money that grinder is nice like and subscribe

[@popperkeg1234]

Thank you for your comment,glad to know I am not on my own in making them this way ,I still think it is ok using my old drills ect,hoping in the near future to try and improve the a grinder a bit,need to get some micrometer dials made,thanks for watching the video.

[@RalfyCustoms]

Cheers Harold, stumbled upon your channel, subbed, thanks for sharing buddy

[@popperkeg1234]

You are welcome and thank you for watching.

[@jackk7030]

G day Harold I haven’t given it any thought until I spotted your video thank you all the best for the festive season 🍺🍺 cheers

[@popperkeg1234]

Thanks for watching the video and all the best also for the festive season.

[@hullygully-3599]

Very informative, have re-watched many times and your videos have motivated me to try and get an old machine myself. Other than Alfred Lyon there is very very few experienced cutter grinding hands on KZbin. How do you re grind normal drills please? Some history and explanation of your home made cutter grinder would be unique if you have the time.

[@mr.picklesworth]

Ypur videos are so insightful. I would love if you did one on making a tap in hobby machine shop. Your videos on making a die were great.

[@popperkeg1234]

Thank you for your comment,might do a video on making a tap would be an interesting video as I have made special taps in the past,keep a lookout,and thanks for watching the video.

[@daveharriman2756]

Nice job, it cuts beautifully too

[@popperkeg1234]

Thank you for watching the video,and thank you for your comment.

[@johnwp111]

Another great video Harold. Maybe next time you show how to grind something, consider using a texted to colour the edge being ground to give contrast when your grinding so it shows up better on the video.

[@popperkeg1234]

will defintaly give it some thought,thanks for the tip and thanks for watching the video.

[@GoCreatehms]

Very interesting video, I've made counter bores from silver steel and drilled/bored the face to fit a pin to act as a pilot, so the pilot isn't in the way when grinding or filing the cutting edges prior to hardening. I'll be giving this method a try, it'll be an interesting exercise. Thanks for the instruction, much appreciated.

[@popperkeg1234]

Thanks for watching the video,glad you found it of interest.

[@haroldpearson6025]

But you need a tool and cutter grinder. Its easer to make one using high carbon steel and harden it after.

[@popperkeg1234]

True and I have made many with tool steel and it will be easier if you do not have a T&C G,but for me with lots of old drills I prefer my way,thanks for watching the video

[@MrUbiquitousTech]

Nicely done!

[@popperkeg1234]

thank you and thank you for watching the video.

[@frankward709]

Very nice. I can come in awful handy Thanks for the video

[@popperkeg1234]

glad you found it of interest and thank's for viewing the video.

When I was training in mid 1970's, we were taught to just drill slightly short of counter-bore depth (by about length of chisel / drill point) then use a second drill bit ground square and off hand grind clearance. I still do the same to counter-bore for 6mm Allen head bolts, most have about 9mm head so 10mm drill bit is much cheaper than a 'proper' counter-bore particularly as it isn't something I use very often. It's interesting to see how it 'should be done' which is pretty much as I imagined. Tool and cutter grinder is something I should have made or acquired years ago, don't really have space for one though (don't have space for anything more than a mini bench lathe and mill) Really miss my big old Colchester. I'll check more of your video's.

[@popperkeg1234]

A good method you descibe and have done the same myself in the past and works well with a little care,thanks for watching the video.

[@philnewcomers9170]

it looks like you make steam hydroplanes from those brass components on the bench .the wheel for back off had a 60 degree angle foe the under cut .iwould say you need a little more clearence but maybe its visual thing geting counterboars to cut is tricky to say the least i used to do it freehand and the components were in ally .The trouble with this is doing it within the bosses time scale. Im glad im retired from all that stuff ttfn&ty

[@popperkeg1234]

There is really enough clearance,it could be the camera angle that is deceiving,the tool does cut very freely,thanks for your comment,appreciated and thank you for watching the video.

[@UncleKennysPlace]

Harold, it's worthwhile to get your music volume and narration volume very close to even, and also consistent, throughout the video.

[@popperkeg1234]

It's the bane of my life is volume narration and and music control,just can't seem to get it right,I am afraid it will have to until I sort it out,thanks for your useful comment and thanks for watching the video.

[@larrymatsumoto7730]

Excellent video Excellent video ,did you make that grinding machine I'd like to get one..

[@popperkeg1234]

Thank you and thanks for watching the video.

[@popperkeg1234]

sorry for the delay in replying,I made the grinder from odds and ends many years ago just to regrind some end mills but I now grind what I can,even beleive it or not some limited surface grinding,not that good though.

[@diggmore1362]

Nice work . Did you make the stent from a Kit

[@popperkeg1234]

No,it's not a Stent,this is a put together contraption made many years ago well before the Stent made an appearance, the base is made from an old mini lathe turret atttachment and the grinding head is an old Swedish bench grinder it does look like a Stent but no,thanks for your reply and thanks for watching the video.

[@lagunafishing]

What's the difference between a counterbore and a countersink please? flat bottomed?

[@popperkeg1234]

More or less the same thing,counterbore has a pilot the countersink is usually angled for countersink screws, flat bottom drills usually are used in pre drilled holes same diam so do not need a pilot,thanks for watching the video.

[@lagunafishing]

@@popperkeg1234 thanks very much :)
