great overview!
She took a cue from you at one point and talked emphatically with her hands. I was confused because I heard her voice and saw your mannerisms.
All the hand-talkers learn from Tony. I spent 6 months in his mountain-top monastery machine shop. Mostly hauling stock up and chips back down again. He assured me it was a spiritual lesson.
@@Blondihacks Did he teach you how to karate chop steel to size!? the ancient techniques!
Sam Coote I saw The Cast Iron Gypsy punch out a metal disk with one blow of her hammer just the other day ;)
Blondihacks was it Ave or TOT? ;-)
Can we all stop for a moment and appreciate that Quinn is providing both imperial and metric degrees for all the angles mentioned in the video? ;)
I can't wait until she graduates to gradians.
Missed the bit where it changed to milliradians? Makes sense as way more accurate than old fashioned degrees ,minutes and seconds!
@@andrewwilson8317
Thank the Sumarians
Прекрасный, познавательный и полный урок по работе на этом станке. Огромное спасибо, с нетерпением жду следующий урок!
Having worked with people who are not very good at teaching has made me very appreciative of those who are. Excellent job on this tutorial!
Back in the late 80's, I worked at a company that made steel type for embossing/debossing the codes on the bottom of food cans (now these codes are printed with an ink-jet printer). I would cut the characters into the steel type pieces using a 3D Pantograph. The cutters we used were created by grinding away half of the end of a 0.250" carbide blank (just the one you had) using a cutter grinder similar to the one you have, then grinding a conical shape with a 0.010" flat tip. The resulting single-flute cutter would cut a 0.020" wide path in the into the steel to produce an embossed character.
Did very similar but we were using the tools on the Taylor Hobson pantograph to cut very fine gates and runners in injection moulding tool die sets. The pursuers were very high so everything had to be perfect. Solid tungsten carbide was used to make the bespoke cutters. Think there still some in the odds and sods drawer in one of my toolmakers toolboxes! Might come in handy some day....
Me during the previous D-bit grinder vids: "Yeah, this is cool, but I don't really see the point."
Me during this video: "HOW WILL I LIVE WITHOUT ONE???"
Great video as always. :-)
I enjoy your videos because they have the same clear-headed sense of purpose as the 50s-era technical films, but with much higher quality recording and the odd interjection from Sprocket.
hands down, best D-bit grinder explaination on youtube
This is a clear, concise, erudite (I googled that), bloody excellent presentation.
You put a lot of thought and effort into this presentation ... and it shows.
Top job - Thanks.
That was a excellent tutorial and went some way to demystify this amazing tool. Thanks Quinn.
Great to see that machine working! All that hard works pays off. Love that demo of the surface finish. Great imaging!
I have watched a few D bit grinder videos but this was the most informative as to how they are used. Thank you.
Really well explained Quinn....now that whole restoration makes sense
I am amazed at the time you spent learning about the various configurations of the similar but different makes of grinders. Thank you for doing that!I have had mine sitting on the bench for over a year but I will now how to at least start to use it. Not only did I learn much, but I finally subscribed.
This was an amazing introduction! I've got a Deckel S1 and almost everything translates very well to this machine.
MASSIVELY helpful to understanding the parts you were disassembling during the rebuild. Thank you!
I am not worthy of being in your presence. Totally impressed with this machine and your knowledge of how to use it.
Timing of finding this was pefect took my new cutter out of the box today! Very Very Helpful. Thank you!!
A really great explanation of an incredibly complex (to me at least) subject. It still eludes me a little, but I feel I've come a long way due to your tutorial. Thank you.
Best instructional video ever! No bs talking all info. Perfect
Hi Quinn. Thank you. This is exactly what I needed. I just bought a D-bit grinder and need to learn how to use it. I learn better in the show me type lesson. Thanks again.
I looked in my bit box and found A-Bit. I've got some learning to do to get to D-Bit. This is a good start!
Great Vid as always, nice clear explanations of complicated stuff. And A-Bit of humor. :)
Nice tutorial Quinn, when I used these types of grinder we used a coarser grinding cup wheel and then finished with a very fine wheel. Guess this shows how times change.👍👍👍
Wow, what a crazy complex machine! Great explanation Quinn! Super clean video shots and editing!
One of the best videos presented on d bit grinder set up and use I've ever seen . Thanks
Most d bit grinder videos I have watched jump around a little but your methodical approach/explanation video was so helpful to simple me. Just got my beautiful old Deckel SO and you have removed the mystery, when seeing the machine for the first time. Thank you so much. One person commented they are fiddly but the process is pleasing to me as I am not in a hurry. Hopefully you will have time to video some advanced uses of the instrument. Cheers.
Thank you for your clear explanation on creating a D-bit tool. I have read the various manuals that I downloaded after buying a Chinese copy D-bit grinder but could not get my head around how to properly setup for each step beyond halving a broken blank carbide bit. Now I understand how to give it a try. 👍😀
Excellent overview of a complicated and often confusing tool. Thank you, Quinn! I have a couple similar machines and your explanation and examples have helped tremendously.
By far and away the best tutorial. These machines are very detailed, and can be very confusing to set up and use. I've been grinding my engraving cutters on a lovely old Scripta - bought via eBay - and no manuals or tutorials were available. So I learned through trial and error.
But after watching this excellent presentation, I take a LOT of comfort in now knowing that the techniques I am using, are in line with Quinn's.
That was really good. Very well laid out and delivered! I would have bet my last dollar D-bit meant drill bit. Thanks for the good info!
Gday Quinn, I didn’t know a single thing about D bit grinder and had no idea how they worked, your overview really made sense to me, I have a lot of trouble understanding things let’s say it takes a lot for me to get the pictures clear in my mind, now I have an understanding of how they work, certainly not an easy machine to master, thank you for explaining this clearly, I really appreciate it, Cheers Matty
Your explanation was so good, i already feel like an expert on these despite I have never used one before. I am now looking for getting one myself. Thank you very much :)
Wow, so that's what all those joints you had to refurbish were for. Very complex but very "right tool for the job". Great video!
All this time while you were rebuilding that machine, I thought it was a drill bit grinder and you were speaking Canadian or something. Even though I already knew there was such a thing as a single flute cutter made from a half round, it didn't click that your grinder was for those. Now it all makes so much more sense! Also, I need a D-bit grinder now, dagnabbit.
You are indeed a great teacher. Thanks!
Fantastic video Quinn! Actually one of the best, and most concise, explanations on the web. I just purchased the Shars single lip grinder and have watched this vid many many times. ha ha. I did make a bit of a bonehead mistake and ground a HSS cutter with the diamond wheel initially which i have since read is a no-no... Diamond for carbide, CBN and Aluminum Oxide for HHS. Thanks again Quinn!
Thanks for making this vid. I own a grinder of this type and have not been able to successfully grind a bit yet. With your helpful information I just might make it happen.
Good stuffs. Thank you for sharing your insights on these very complex bit types.
I have to quit watching this channel. Every new episode reminds me of something else I need to buy.
I own this damn thing because of Stefan’s video, so I know the feeling. 🤣
@@Blondihacks Thought you would do this in a German accent.
This is general problem !
@@Blondihacks I understand the need of the grinder, after I purchased an Alexander panto-graph after watching Stefan channel 3 years ago :)))
But it can be used for a LOT of sharpening and grinding tasks in the hobby shop :)
Great video! Thank you !
I've been seeing that quite often myself, been off work for a few weeks so can't wait to get back on the job to get some of my wants for the shop.
Thanks for the explanation, and great job on the camera work!
Very good tutorial. For a minute there I thought I was watching Robin Renzetti.
The highest praise! ☺️☺️
You've inspired me. I could use a d-bit grinder to shape my right-hand fingernails for guitar picking. Proper shaping is essential for surviving steel strings. I can use any old kind of sander to clearancing my left-hand fingernails for fretting. Thanks!
You are a recent discovery for me, Quinn, and I'm compelled to express my appreciation. You are so cool! You're a clear headed and knowledgable communicator with a sharp sense of humour to demonstrate that you don't take yourself too seriously. How'd you get so smart?!!! Machinists rule. Love from Vancouver. Let's do coffee!
🇨🇦🎉
Thanx for that! My D bit grinder manual is hopeless so your explanation helps a lot.
Some other uses for it are single lip spot drills for tiny spots. If it breaks off in the spot you can usually get it out easily. Tapered hexagon reamers. You are right it is all in the setup. But after some time doing it it is a great tool to have in the shop.
This is the 2nd time I've watched this video. Makes more sense to me now. Thank you.
Another excellent video Quinn. Your videos are very informative. I have been learning a lot, thank you.
Your instructional videos are truly superb. ❤
You do such a great job explaining things and I love ❤ you sense of humor. 🤗
Nice explanation. I learned how to use these at the shop I did my tool and die apprenticeship and we did it mostly the same way you describe except that we did the relief of the bottom of the cutter with a rotation as well so the final relief you did wasn't needed. The main reason we used the d-bits was for work in harden steel and carbide d-bits did a great job even in 50+ RHC hardness steel. These grinders also do a good job of refacing the bottom of an end-mill if all you need to do is get rid of a dulled corner.
Oh interesting! Yes, that would be a good way to do the end relief as well!
A great learning experience. Thanks, Blondi !
Yay!! It's time for Blondihacks!!
@Tom Faigle Same here. I was following Quinn's blog during the Veronica build, but my computer let out all the magic smoke, and I couldn't find it afterward. So glad I found her TH-cam channel.
Holy hell! The basics! D bit grinders are overwhelming
That was a fun video, thanks! I have made a couple crude tools of this fashion on the 4-axis lathe at my work. Surfaces aren't that great (milling instead of grinding) and I'm limited to tool steel at best. I've only used them for odd channels in Delton so I actually just used cold rolled steel. My favorite one (well, this was a turning tool, not a d bit) was a ID thread tool for a 4 lead TR (metric Acme). Same basic process, but the business part protrudes from the round portion and I had to put relief on the lead edge by hand because I was one axis short. Just occured to me, that grinder would be a great way to make that type of tool as well. Hmmm... You could also make some great solid carbide micro boring bars using that thing.
very good machine use this 25 years ago.. can do grinding of single lip, end mill and drill with it.. very usefull.
I appreciate the way you talk through your decisions. You're a very good instructor. I have almost none of this equipment and yet I make stuff. I know we've chatted before about your dad and his reloading well I do that too. And I need to make a debate for making a custom bullet mold. The debate will be basically half the profile of the bullet plus some relief angles. I'm having to cut this pretty much all by hand I don't have a fancy tool like yours but just talking through the angles and emotions makes that all easier. I'm thinking of me make the wood equivalent of a color block to hold the device so that I can make all my angles very repeatable.
I'm in the process of restoring a SU2 as well, so first big thanks to your video on the restoration.
Now on the alignment dot - I think the indexing knob (with dot at 90 degrees) can be independently positioned from the toothed gear (? the one with dot showing thru the tiny window). Therefore, you can align them so that when the red dot is showing through the window, the dot at 90 degree mark is also on the mark.
Great video as usual, think I need to go over this one again to fully understand how to do it 😉
Happiness is a How To video. Thank You.
Thank you Quinn, another excellent and informative video.
You, Quinn, are the reason I don't get anything done! I've sat here and watched/listened to you show me how to grind a tool that I'll never need, to do a job I'll never do, on a milling machine that I don't even have the space for ... Ggrrrrr!!!!!
a man of many parts i think you are too busy grinding your own tool
I have always want to learn how to use one, thanks Quinn!
I have not seen Dbit grinders in use before. This is a great video that I think explains the process really well.
I have a small tool and cutter grinder than has a ball nose end mill attachment. My grinder doesn’t have all the swivel stuff of a full T and C but I wonder I’d I can get it to make a Dbit. As you said I now have enough information to be dangerous.
We have one of those at work to sharpen counter cutter bits. Cool machine!
It looks like a baby Monoset grinder. I used one of those for several years while I was working in the grind room of the aerospace company I was working for. Those were amazing machines... you could do anything on them. This D-Bit grinder looks like everything anyone would need in a small shop. Pretty Cool!!!
Thanks especially for the radius/vernier info. Have been looking for help with that for a while.
So helpful! Thank you! I think now I could get mine to do what I want
If you ever start to teach machining I would definitely sign up for classes Thank you for the videos
Great video, presentation and explanations, thank you!
I have a "DECKEL" Grinder you mentioned....but until now it was black magic for me....(have tried some experementials with it, Resharpening etc)....now i will have a closer look to this great machine....the key is to FULLY understand all the functions, then you can use the Magic of it....thanks for the Vid and regards from Germany :)
Nice detailed description. A big help. Thanks.
Very nice video Quinn, I use a Gorton grinder for engraving bits. same design thank you take care.
Wow! Great tutorial Quinn. I used our Deckel a few years ago, but haven't since. Great to get a refresh, if I ever need it. SUBSCRIBE.
Thanks for the sub! 😀
This is going to be a popular video. I was not aware of how complicated these beasts were.
Got my new D bit grinder out the box last week. Test sharpened a drill bit and found that all the scales need to be set. The scales spin on the machine knuckle and can be set , I didn't know that and I ended up with one odd looking drill bit. Need to spend some time on the machine when I have some time.
Very good video on the basics of the d bit grinder, Thanks Blondihacks
Tidy Threads where did you get your new grinder and approximately how much is a brand new one. I'm here in the UK but I'd still like to know a ball park figure
@@samrodian919 Hi, Not cheap but it will pay for it's self once i learn how to sharpen carbide end mills. I got it from warco. www.warco.co.uk/metal-grinders/303371-universal-tool-cutter-grinder.html
I loved your vid where you sat in a chair and talked about your life's journey...you are extremely intelligent
Knowing just enough to be dangerous is my life motto
Great video, I might look at getting one to sharpen my woodturning chisels... 😁
I have had one of these lying around the shop for more than 10 years. Experimented with it occasionally but never really understood it. Now I NEED to go to the shop and make one of those single flutes :) Mine also has a drill bit sharpening jig. Would be great if you can make a video about using that jig.
nice video, my dad is a mechanic, and had something similar to this (but was for cylinder head valve grinding, ie to reface the stem and anglular faces to repair them). but as a side note, for jewelers this d-bit might be better known as a "Graver" it is a hand cutter used by engravers to cut patterns in metal bracelets, or for the cutter used in a 'rose engine'- what engraves the pattern on a pocket watch dial)
Much needed video - good explanation.
Knowing just enough to be dangerous is my specialty, LET'S GO!
Wow - you’ve really done your homework there - Thanks!
Quinn one way to think of the geometry is like a plane, nose of the plane is the 'front' of the cutter, and the axis of motion correspond to pitch, yaw, and bank, so this is a way of visualising what the angles mean, compounded it is like an aircraft turning, banking and climbing height at the same time!
What a brilliant video Quinn, thank you for the introduction to D bit grinding! Your commentary is precise and very understandable. I wish I could find one of these machines over here in England but they are like gold dust and so expensive. Keep safe!
Heavens to mergatroid, I have been waiting so sooo looong for the tool grinding video. Nice! I'm going to have a sandwich to celebrate. Looks like you got a fist-bump from Tony, too! Sweet! Many thanks!
This video will help so many people. 👍🏼
You kept asking, so here you go. 😁 Meanwhile, your last video got me to buy a 3M deburring/polishing wheel. It works so well!
Your explanation is very good
The D bit comes from looking at the cutter end on, the single flat on the round shank makes it look like a letter D. Simple as that! So many of these out there, I have a Deckel version and it was used to sharpen cutters for a 3 d pantograph engraver. Not used much since going to indexed tools in the five axis mill.
G'day Quinn, I bought a clone recently but haven't used it yet, so this video is perfect timing! I've watched other videos on the topic but never really got it. Now I get it! Many thanks and I look forward to more. Sharpening drills, end mills, taps, reamers?
You bet! More videos coming
I was just thinking while watching, if this You Tube thing doesn't work out, you can be a Hand Model!
Very clear and understandable, thanks
I didn't realize I need one of these until now.
Made a few wheel parts which now has every different wheel its own and changing goes very fast 😊
This was very entertaining. Machine still a mystery, but entertained. Probably never gonna see one in real life anyway.
Another good site on the subject: The Tool And Die Guy.
I have a Shars knock-off. I struggled with setting it up, actually still do. But on many things just using a commercial tool as a guide helps a lot. Also found that exact setting is not required. I can do quick and dirty set, grind and get away with it very often. The drill bit sharpening fixture that came with it isn't worth the time to set it up. You can just put the bit in a collet , eyeball the settings and be done in a short time. Spending a bit more time you can do split points on large bits. Bits cut great.
I had some brazed carbide lathe tools that were dull. Was quick and easy to sharpen. Use dust collection & a mask while grinding carbide. As for lathe form tools, that gets to be a trickier thing. I know that you are not supposed to use diamond on steel, But, the Chinese wheels are pretty cheap and the CBN wheels are more expensive. Most of the time I just leave the diamond on and it has lasted well. I don't like the grit, dust, rapid wear of the Al-Oxide wheels. The very thin cut-off wheel is very fragile!
I bought the Shars when they had it on sale a couple of years ago. The fit of some of the parts is less than ideal. The scales are crude. The instructions are --- worthless, look for the online Deckel ones. I added a second work light on the left, helped a lot. Would I buy it a gain?? Maybe.
Yes, the Tool And Die Guy’s series is what got me started with this machine. I shouted him out earlier in this series. Very helpful videos.
Very well explained.
Thanks for posting this! Now I can watch Stefan’s videos without scratching my chin and saying “hmm. yes. grinding.”
Great video!!👍
With every video I see, I gain new respect for machinists. If the average person could see what is involved in your work, they'd be more appreciative and respectful of things mechanical. 😊💪👏
Amazing explanation, welll done I give you 10 / 10
