To grind on the side or not? It's a question that is often asked but rarely answered with such simple logic. Brilliant video . As for the precision haircut , I just hope the day jobs going well.
Well done, sir! You are indeed a rare breed. As a machinist/ tool maker with 45 years experience, I have run into only a handful of guys with your skills and temperament. Thank you for the great videos and be well in these crazy times, Your friend from across-the-pond
How is it possible that you don’t have half a million subscribers so far. Your explanations are spot on, your skills as a machinist are superb and you are absolutely entertaining. Cheers Mr. Chrispin.
I liked the idea from the moment I saw it on the piston ring videos, but I hadn't contemplated the trepanning style side relief required. Thanks for the explanation!
I was having a thought similar to this the other day for making a custom tool for making many parts... this has inspired me to give my new grinder a whirl.
This video is a very good description of the basics of hand grinding a lathe tool. Sadly a large portion of today's machinist don't have the skills needed to grind a tool as displayed in this video. I have managed a few production machine shops in this modern world of cnc machines and the "machinists" expect you should just order a tool to do whatever job hits the floor. And it's not always possible or neccesarily cost effective to order a tool to create a particular feature. In fact a lot of people calling themselves machinist don't have the basic understanding of cutting tool geometry and unless you select the tool for them weather it is an endmill or a carbide insert they lack the basic understanding neccessary to select the tool for the job.
Thank you for the demonstration! Your piston ring video gave me the idea to look through the old HSS tools I have and I ran across a small trepanning tool that someone had ground up. I touched it up and cut a ring from an aluminum bar to try it out. Next step is a trumpet chamfering tool when I get the chance!
need those 26 year old eyes these days. great to see ha, these vids, having being a tool maker 40 odd years ago, then went into building as everything closed around here engineering wise, just set up a shop at home, great to try and keep up with you, keep going. thanks again for your knowledge
I sincerely appreciate your efforts in making these videos. I learn a lot by watching your efforts. Sorry you are in lock-down again; this is getting old. Also, I am very glad that you are so young as it means (I hope) that we will have videos for many years to come. Take care.
Thanks. The videos take allot of effort to mak but I am glad they are of some use. People put allot of effort in to helping me when I was first learning so I'm happy to be spreading their word.
Superb hand grinding skill! Amazing you can tease that shape out with a 6 inch abrasive cylinder. The use of this tool in your piston ring video is equally clever. Just describing this shape correctly in 3D CAD would likely take more time than it took you to make it. Your grinding skill is rivaled only by your hat throwing skill. Great Job. You inspire me, I'm going out to my shop now to practice throwing.
Thank you for another great video, hopefully with the coming month’s getting warmer might we get to see some more of your workmanship on your engine build. Many thanks... Phil
What a great video 👍👍👍👍👍👍👍. Thank you Mr Crispin 🙏. Although I am already a subscriber, I confess I haven’t seen much of your content in a while. I need to do my part and devote some binge watching and catch up. I’ll work on that the next couple of days 👍👍😎👍👍
Yes, Joe pi is the reason why I seller out the $ money for a subscription. They had an introductory deal. Not sure what ill do after that. Maybe they will all switch to rumble
A very impressive piece of offhand grinding! Unfortunately, my eyesight now restricts my freehand grinding to larger work. Another very professional and well narrated video Mr. Crispin. Many thanks for your time and effort.
Educational as always. As for the in roll adds. I do not think you need to remove them. I think most of us watching do not mind sticking about 30 seconds longer.
Glad you got rid of all those darned ads that youtube is saturating every channel with. I've hand ground several similar tools for internal dove tail seals. Pretty scary putting dove tails twelve inches down inside a bore on a manual lathe, very little feel.
@@thecorbies I use Premium, no ads and the creators still get some funds out of it (VERY little I know, but I like to think I'm doing the right thing :)
Hi, no unfortunately I really try not to take on any work. I do the TH-cam and home work as a hobby and working to dates and requirements for people makes it quite hard work. Cheers.
My Trumpet is appearing, sounds most painful 😨. Great to see the shadow graph imaging, excellent work, thanks for sharing. Best regards from the Black Country. John.
Are those Jones and shipman grinders I see in the background???. Greetings from an old Scotman living in South Africa . Worked in rolls royce Derby no 6 shop in 1968(toolroom) That 540 J@S would have made quick work of that form tool as long as you had a universal swivel vice.. like your channel keep up the good work..
Hi yes it's a J&S 540 but it's not actually running. I need to give it a once over and re so all the wiring. The machine somewhere next to it is a Dormer tool and cutter grinder. That one is running but I need to make the wheel arbours. Basically I have not yet set myself up for grinding but I will get there. I'm at RR myself. Quite a few of my colleagues talk about days in 6 shop but I think they would have been there in the 70's /80's
No shadow graph. How about a SUB microscope, they usually all come with some simple feature measurement software. I have used them for measuring optical and fibre optic features and they work great and can be accurate if calibrated.
@@DrKnow65 Err,I think subs use periscopes. Parascopes sound suspiciously like magnifying devices used by people who jump out of aeroplanes,even though the aeroplane is in perfect working order.
Very nice, as always! If you are inclined and able, I would very much appreciate follow-up videos on Violin Chamfering and Egg Chamfering Tools. These are definitely not well-represented in the literature! Even just a few tips would be helpful...
A question: While your hand ground tool was quite successful, you made the rings, are tools like this ground/fashioned on a tool and cutter grinder? I imagine a skilled fellow could grind intricate details with such a piece of equipment. Thanks for taking all the time to show what you do. I enjoy learning and hope to soon be putting all these tips bits to use.
Yes a cutter grinder or in this case even a surface grinder would be a much more effective way to do it. Set the sine chuck to the required angles and then just put the required form on the wheel and grind each side in turn.
Thank you.... The content was very helpful..... as a side note please stop taking the stones from my locker. or as a result i will be forced to leave you a pile of the lowest even numerical value on the bottom of you locker..LOL
I don't think there is such a thing as "enough grinding videos" that would suggest that there are enough videos about using a lathe, a mill, a welding torch.... I say: no sir! There is always room for more content of someone showing off his/her/their trade or hobby!

Good to see there is someone else in world who still grinds HSS cutters.
I agree 100% I am waiting for the why don’t you use a wire eroder comment :)
I imagine there are many people that grind HSS tools, not so many that do it as well as this young man though.

Great video again the shadow graft comes in to it own for such fine work enjoy it from start to finish thanks for the effort you but into these video
Thank you so much for showing this excellent technique. BTW, I'm watching this video in the morning (GMT-6), so I'm wide awake, promise :)

Tool grinding is one of those unappreciated aspects of machining because we get so spoiled having tool holders with carbide inserts and whatnot.
It used to be a profession ,people were paid to grind tools all day long.

Curious: What is Trumpet Chamfering used for? Looks neat!
Have a look at my video 'making piston rings'

At 1:11 I couldn’t help but notice the Kerry Super 8 drill! Good taste, I’ve got 2. One I restored in my channel.
I need to replace the spindle bearings actually. Is that something you did in your restoration?
@@MrCrispinEnterprises I replaced all the bearings on mine. You'll need a press and I can send over the bearing part numbers
That's would be great. It's mr_crispin@hotmail.com
Barbers with 6ft long arms are making a bloody fortune!
So what precisely does this do to the piston to make it better than not having it? I would be worried about getting ring flutter.
I just didn't want sharp edges that could damage the piston on assembly.
I don't think there is such a thing as "enough grinding videos" that would suggest that there are enough videos about using a lathe, a mill, a welding torch....
I say: no sir! There is always room for more content of someone showing off his/her/their trade or hobby!
If we're going the have infinite grind videos, may I suggest adding a little "Bump" to the videos. Everybody enjoys a little bump and grind.
