Thanks for the video, you made me laugh with the center hole/divot issue 😂

What grits and type of wheels are you using? Thanks. Enjoy watching!

I was watching intently about center drilling M2 with Carbide. Anytime I have cut bearing races, it was a squealing contest.

Really cool project. THANKS

Excellent video,thank a lot.

for extra points - helical spiral flutes for chip clearance

You sure know your stuff! I enjoy your videos, and I always learn Very clever thread grinding setup.

Well done. That is a bucket load of work young fellow. BC

What is your grinding wheel that you used for the thread grind? I am guessing that it is a fairly fine grain wheel to get the narrow point of the V to hold up. Very cool build, thanks for sharing.

Nothin but NICE!

Wow ! Huge project, thank-you so much for your efforts ! Do you ever lap your centers ?

Very cool, what a fun exercise. I’ve always wanted to see thread grinding being done.

I love this stuff. Thank you so much for the video.

I`m a simple man - I see a 3 flute drill and i`m willing to check it out... There is nothing like a good 3 flute drill, except for a solid carbide 3 flute drill... Fucking nice! Best regards! Steuss

Great info! Thank you for putting this together. Providing the right wheels to use and the tip of leaving the center nub are very helpful. Keep these videos coming.

nice video. It is good to see someone who knows what they are doing.

Ive seen others take time balancing wheels. No? Yes?

I'm not quite following your procedure of loosening / tightening the lock nuts on the sensitive work head as you spin it. I'm assuming that the arbor is in a collet in the work head and a center on the tailstock. If they're not pointing at each other, there's "binding" on the tailstock center and when the lock nut is loosened off, the work head will swivel slightly into its "happy place" ? Never seen it done like that before.

where were you when I needed someone to show me how to grind tools 45 years ago. I really like to watch you sharpen tools. nice videos. keep them up. thanks

Excellent educational video thank you 🎉

Hi I have two hybco fixtures and I use one to sharpen gun drills. These contraptions really are worth having. They sharpen taps, drills counter sinks and reamers. I have had them for decades and they keep working. Nice video. I have then on a B&S 13 and a Cincinnati #2. Nobody knows how to run them anymore other than old guys. I enjoyed your video. Keep them up.

Bro, you just like making sparks.

I always wondered how a 3 flute drill is sharpened, now I know. Do most 3 flute drills not have the center "chisel point" of common 2 flute drill bits? So they require a pilot hole to be drilled first? Thanks for the demonstration !

Making my day watching you….Paul in Florida❤

Cool video, I have not seen many three flute drill sharpenings! I am wondering how a true three flute drill would sharpen as this is a non-center cutting drill. Looks to be in effect a reamer. I know they definitely make three flute carbide drills which center cut, so it would be interesting to see those resharpened. Or a HSS/HSCO/PM equivalent.

As Joe Pesci said in ‘My Cousin Vinny’. “Those must be Magic Grits”

Great to see your channel growing…lots of great info…lots over my capabilities and equipment…but one day!…Paul in Florida

I have been looking for an end mill sharpening video for the longest time. Thank you for making one!

Is this the updated brushless version or the brush style motor? And all must remember it's a combo and a compact unit.

Your wife's a champ for filming this. Subscribed. Thank you. Ive got a Harig and a surface grinder. Looking to undersize a 12mm reamer. How far you reckon I can go before I need to re-grind the relief? A few thou off the Radius? Any rules of thumb?

I appreciate the Sincerity with which you talked about trying to set a good example for people like myself who didn’t get formal training in machine shop tools. It would be easy for me to learn bad habits unknowingly and your efforts help keep me safe in my machinist journey

Well done, great presentation. Enjoyed your video.

Thanks!

I think I read somewhere that some reamers are deliberately made with unequal tooth spacing to reduce chatter. Rifle chambering reamers maybe?

Nice. I enjoyed your work.

Excellent work 👌🏻👌🏻👌🏻

Really appreciate this content. Got a kolee couple years ago and the use of machine is a deep subject. Steve summers did some videos on his. Keep em coming!

Nice one! For the future: Inch sized taper pins are usually a taper of 1:48 (1/4 per foot) or 1.193489 deg. Metric taper pins are 1:50 or 1.14576 deg. Clock maker pins and die maker reamers can be lots of different angles.

Great, all these machines came from the factory Guards and possibly other safety devices 😉🇨🇦

This was perfect. Thank you!

Best explanation of sharpening I’ve seen, thank you. Your channel is great.

Excellently explained, loved the video, Thanks so much.

Just one question, is the axial movement designed to accommodate grinding the flanks of the teeth if the wheel is shaped to the tooth profile? I have just discovered your site and am enjoying your videos a lot.

Your clutch must have slipped when you disengaged the feed sins you did not damage the thread at two accounts! As "joergengeerds360" says, Do as Joe Pie does! Thanks for sharing!

Do you not have to redo the leedin chamfer? Just asking, i don’t know anything about machining.

Thanks for this and the previous show and tell! No excuse now for not sharpening my dull slot and end mills. Cheers 👍

These sharpening videos are brilliant. I’ve been entertaining picking up a tool / cutter grinder but haven’t found good info to help me understand what’s involved. Cheers! 👍👍

the camera operator needs a bonus

Thanks!

Another great video! Thanks for doing these--they are great.
