You have a gift for presenting these complicated details. I have been a hobbyist for many years and watch a lot of educational videos. Yours are the MOST practical I have ever watched.
Thanks for taking the time to explain tool making in terms we beginners can grasp. I've had one of my fathers old tools in the bottom of my (inherited) toolbox for over 40 years and now I know what it's for - it's a home-made boring bar!
Thank you for your excellent and helpful videos. Yesterday I turned a MK3 taper on my lathe and was quite frustrated because of the poor surface of the product. It was my first attempt to turn steel using "home made" HSS lathe tools. Following your precise description I just increased the cutting angles of my tools - and it worked like a charm.
You are correct about HSS giving a better finish, especially in aluminium and other easy to cut materials. Steel is a bit of a different animal. What I like to do, is use a combination of both. Carbide inserts for roughing (they beat HSS in roughing 100 to 0) and then HSS for finishing when a good surface finish is required.
well done, by far the best explanation of tool grinding I have seen. I particularly liked the wooden models, far better than trying to understand a diagram.
Excellent video I like the use of the wooden enlargements to demonstrate the angels of the cuts.I have used a lathe before pretty much just for cleaning up dies at a plastic factory but didn't do much turning with it. I've now gotten one of the mini lathes to play around with and I noticed that I wasn't cutting the material as clean as it should, after investigation I realized I needed to cut different angles for different uses, your video was just what I needed. Thanks
My new instructor! I knew 5 min into this vid you were spot on. I hope you get 10ft of snow & make more vids (...just kidding) We are all hungry for this type of very clear, complete intruction. Tubalcain is awesome due to his extreme detail and info. Can't wait to see all your stuff & pick your brain. God Bless
Thanks for this video Iam starting to learn how to sharpen bits I have a small nano lathe and it is similar to a Sherline in size of what it can do Their bits are different than bigger Lathes The last bit you showed may help me to make a fine finish on mine Also The bit that looks similar to a thread cutting bit Would be an interesting one to see
Nice videos and Good to hear someone from my old territory of So NH and No Mass. - I have all my students grind a HSS RH tool like I had to do in 1984 and they understand tools much better just from doing it and using it on the first projects they make. It even helps them understand carbide tooling and inserts.
Real newbee here. Thanks for this video - I followed your directions and got it to work the first time. I like the simple approach. Others put too many different angles on the tool that it confuses the beginner. Your single angle method takes all the mystery out of it.
Yup It is much simpler and gives decent results. Best part is it gives a good starting point to experiment with some different angles to get one you like best for certain materials.
I like your way of explaining things. The first part of the angles were confusing though. Otherwise I am looking forward for the next part, especially how to cut your hss bits.
Very good video. Your best so far. Lots of info and common sense. News I can use. Best video I've seen. Btw, I thought of a project... a collet holder. Lots of people who've with mid-size laths still need to do small work. How about an ER40 collet chuck that could be used in a 4-jaw chuck. Why a 4-jaw? For those using sloppy used equipment or the China equivalent. The 4-jaw offers some control in getting things centered up. Why ER40? Good collet size range & easier than 5c. Thanks again.
I made a cutting tool from a piece of 3/8x 3/8 square stock and cut a slot in the end with a hole opposed to the slot with a set screw to hold the cutting tip I install into the slot. I found the I can take a New Carbide circular saw blade and cut the cutting teeth off with my plasma cutter and then file them to fit my square stock. It works Awesome and its Extremely inexpensive to get a Carbide cutting tool.
Great video. I've been getting really bad results and it very well be the scrap metals I have lying around. So I've bee diving into grinders, dressers and such...
The one thing I have learned over time is do not grind down the top of the tool till you no longer have the original sharp corner or top of the tool. If you do that means you have to adjust the tool holder for each tool to insure it is on the piece centerline you turn. keeping the original top of tool you can always be sure if you change bits in that holder it will always be set at the right height.
Good to hear the accent - I used to race at New England dragway in Epping and grew up in Burlington, Mass. - Now teaching machine shop in Florida - good videos
Yes... It's only $25. My comment was partially in response to one of Halligan142's other videos asking for project ideas. An ER collet holder is pretty simple and useful but has a lot of machine operations - turning, facing, taper, threading inside and out, etc. They're cheap to buy but would probably be instructive for a lot of is viewers and I think almost everyone can find the scrap for one.
Hi, Great video,explained well,tool grinding is definitely an art,tried you're method good finish on alloy steel and as well as on mild steel. Thanks for sharing,,,,,
the most important thing is in your first comment, what grade of tool bit. If you can afford a lathe you can afford a good tool bit. As far as clearance goes, for brass, alum ,plastic, more angle for faster feeds, less angles for tuffer materials or interrupted cuts. Clearances and angles are a trade off, more clearances means less stability or rigity. As my maple syrup cooks I'll be watching #2 JIM
I bought a Southbend 9 in lathe and I would like to know how to change the direction of the autofeed, both crossfeed and longitudinal. Thanks for your videos, very helpfull. MB
Blou MichelB Look to the left of the spindle. You'll see a handle sticking out. Depending on your model it may have a plunger on it like the gearbox. Pull it out and you can move it to one of 3 positions. Center is neutral. If it's just a handle with no plunger swing open the gear cover. You'll see a square head bolt holding it in place. Lossen it and you can move it.
show me a tangental grind on Hss !2 degrees angels & in normal; geometry tooling as you use, See the Tangenital dimmed tool holders? whats your opinion. praps a self-build holder.
nice video keep it up im 2nd year apprentice and i thought the radius on the cutting edge would be better than a point, As the point would heat up to quick and fracture
yes boxfords are very popular here all the schools used them so theres loads about. parts are pricey though ebay being the best place. a model A underdrive on a cabinet can fetch prices up to £1000 thats the gearbox model
Thank you for the up load of this video. what addition is this book. I was not able to google it nor i was able to find it in amazon. could you please post some more info about this book. Thanks
Assuming you mean 'How to Run a Lathe' by South Bend Lathe Works, I just found it on Amazon (UK). Many editions (but the same basic data inside), and there are 'used' copies at very reasonable prices.
Hone the tool as sharp possible and it should love the 12L14 or any other leaded stock. Ive never bothered with one, only seen attempts on utube. The theory on the tool, it should love any free machining stock, look forward to your tests.
You make the point that Mr. P (?) has better videos out there and we should check them out. I cannot find anything on grinding lathe tools by Mr. P. Can you give a URL where we can view them? Thanks.
Carbide bits will only cut continuous cuts, if you turn a square piece of stock down it will chip the carbide tool bit, which is another downside of carbide.
Thank you so muck for doing this videos, they are really awesome. But i think you're wrong when you say that other people like Tubal Cain have done this better because i learn more from yours than his! :)
Do any of your vids show how to make the hole in the end of the shaft to fit the tailstock? For instance I want to mount a 1" shaft I don't know how to mark the center and what to cut it out with so it fits onto the tailstock without slopping around? Also if anyone knows a good video on making outside chamfers and chamfer tooling that would be of huge help too. Thanks for any info!
PS I almost didn't subscribe to this channel because the first thing I seen was snow lol. I am so not ready for this winter. Of course I don't know anyone that is we were still buring wood in freaking april.
Any industrial supplier will have decent wheels. Nortons are nice but more expensive. I just use the ones that came with the grinder. I think they're 60 and 80 grit
i would not recommend moving to florida. ive lived in the orlando, tampa, and Jacksonville area. ive been here since 1998. when i 1st moved here it was great. we had a long summer, short fall winter and spring. now its just a hot summer and a super hot summer. its too damn hot. with the climate changing it has just gotten ridiculous. its 95+ degrees & 95% humidity over 300 days a year now. when you go outside its like walking into an oven. from my front door to my car i start sweating! we do have a FEW cooler days a year now, but there is not seasons any longer. i would highly highly highly recommend you come stay for 3 or 4 weeks in july or august before you commit to moving here. i personally am moving to the Oregon / Washington border where its 50 to 75 degrees over 300 days a year. absolutely gorgeous place, you have the mountains and Pacific Northwest forests as well. gets very very little snow just because it doesnt get cold enough, but it does rain most of the winter. id rather have rain over snow any day of the week. Real estate is more expensive in the Washington area, but the overall cost of living is much cheaper than here in florida, and wages are alot more in Washington as well. Minimum wage here in Florida is i believe 8.75 an hour. Alot of places pay like 10$ an hour, ya take the same job out in Washington and your pay doubles. Food servers make around 20 to 22$ an hour in the Washington/Oregon area. Anyway, i very much enjoyed the video. i just purchased a mini lathe from grizzly and i am trying to learn everything i can. Again thanks for sharing this with us.
Hi Jerry ! Seen all your vids, and liked every one of them.... email me when you find the time? We have some things in common related to machining and machinery (I am an electronics engineer and I am somewhat self-educated re machining as well) My main interest related to this ,is live steam/gas miniature engines. Cheers and thanks for the vids ! Keep'em comin' ! Paddy
carbide @ 1200 would be a diameter of 5/8 3/4 tops, even then that's fast, maybe for a small finishing cut, hi rpm/ slow feed I picked up a diamond dremel wheel ebay for 5$ and works great for ever
I think you and many others have a misconception about carbid tools and inserts and HSS tools bits. Did you know they are selling HSS inserts and you can mill or turn hard materials with those at low speeds and feeds. It's possible to machine hard material with HSS with the proper setting and have good quality finish. And I think you're doing something wrong when you use carbide tooling on your lathe.

thank you. great video for a novice like me. thorough and interesting. keep up the great work.
Good to hear the accent - I used to race at New England dragway in Epping and grew up in Burlington, Mass. - Now teaching machine shop in Florida - good videos
Nice! I'm actually very close to Burlington

thanks another great video i have a boxford lathe which is the british clone of the southbend keep em coming
thanks good video really helped me to understand sharpening tool bits alot better.
Thank You for the information, very clear and helpful.
I was wondering why you never turned at higher RPM's in other videos now I know why, thanks.
Thank you for sharing all this information.
show me a tangental grind on Hss !2 degrees angels & in normal; geometry tooling as you use, See the Tangenital dimmed tool holders? whats your opinion. praps a self-build holder.
just wondering, can you add a chamfer with a left hand tool bit or do you have to grind a different type of bit
nice video keep it up
im 2nd year apprentice and i thought the radius on the cutting edge would be better than a point, As the point would heat up to quick and fracture
yes boxfords are very popular here all the schools used them so theres loads about. parts are pricey though ebay being the best place. a model A underdrive on a cabinet can fetch prices up to £1000 thats the gearbox model
do you add a back rake on the boring blank
Loved it thanks for the tutorial. Best Wishes n Blessings. Keith Noneya
