#tipblitz19 - วิทยาศาสตร์และเทคโนโลยี
Great video! I love the dead centre tip. But there's a neat trick you left out... th-cam.com/video/KqlcCdSak2A/w-d-xo.html
Whoa, that’s awesome!! Now that’s how you do a response video. 😀 Thanks for sharing! That’s a great tip and I love how you called out the limitations responsibly. Thanks for sharing!
@@Blondihacks Well thank you for the kind words! 😊
@@andypughtube That's true. The work is only being gripped with this method, not physically constrained by the jaws as it would be normally. Yes, you want to take extra care with unbalanced workpieces.
Dang. I knew about the copper jaws thing, and about reversals, but the dead center trick took the ribbon home. Nifty!
I agree, great tip!
Would it be helpfull to use some sort of tap follower so you do not have to readjust the distance to the life center while finding the center position?
I don't own a lathe, but it would be nice to have one I just don't have the space. I totally agree that dead center trick gets the ribbon. That was impressive enough that was going to be my comment and someone beat me to it.
........by a year. 😁
I also liked using that angle metal in the vise for a second bend. No lathe, but I have a vice. 😁
I just recently joined your channel and even though I don't have the machining tools that you do the procedures you show the imagery in your videos and your precise descriptions of your procedures is as good as it gets. Everything makes perfect sense and the added humor is the kicker. This is great stuff that you're showing.
How about a video on improvements to a drill press table to improve accuracy or repeatability.
Another tip for the four jaw that I believe I learned from Tom at 'Tom's Techniques' is to clone your four jaw chuck key and use both keys simultaneously on opposite jaws. This really facilitates matters when truing work.
I was going to suggest the same thing, I use a short small chuck key for the rear and turn both front and back at the same time for large adjustments and getting close. Then fine tune with the main chuck key one at a time.
By this method you can often dial in to +/- 0.0001" TIR within 2 minutes from chucking part up... to dialied in.
I used to hate dialing in a 4 jaw, but now...I never even use the 3 jaw lol since it would take more time to swap out the jaws than to just dial in.
But this is a great video still, she definitely knows her stuff.
Good point. If I did that I *KNOW* that I'd have to put a chain or something on it because I'd forget that 2nd one. Make the handle a giant blaze orange plastic disc or something like that. UFO? Nah, just my 2nd chuck key.
Great tip. Probably could even 3D print it since you won't be using much pressure when doing the simultaneous motions.
For the copper soft jaws i use a short offcut of copper tube/pipe, set the jaw point with a round bar held firmly in the chuck. Once tight squash the sides with grips, you then have to mark and cut the tabs similarly to the way you did but leave the rest closed as it helps stop the softjaws opening up once they have been used a few times. They end up the same as yours but closed at the back part.
Yep, and while she's make the first one you'll be finishing the fourth.
Always get a warm feeling when in your intros you go from badass boss, to speaking with the sweetest children storyteller voice and demeanor. And it doesn't disappoint when your videos always range in between (more like the latter!). Excellent work, Quinn! Forever a fan!
I just bought a lathe, old school Harrison. £250 delivered with a 3 and 4 jaw chuck and "loads of tooling". Wohoo! Can't wait to make something using these tricks :)
I liked the centering up the off center bar trick😊
I like the dial indicator mount on the quick change. How about making a video on that?!
That double dead center trick is great! I would have only thought to use the dead center in the tailstock.
Nicely put together video Quinn. I learn something every time I watch your videos. I tried making some soft jaws out of 14ga brass sheet and it didn’t work out so well. Now I see where I went wrong. Thank you. Keep up the great work. I always enjoy your videos!
I must be REALLY stupid since I found these tricks brilliant. Thanks !
Excellent tip with the dead center! I’ve always used a 100 year old 10 to 1 “wiggly” & my calibrated eyeball, your method is better.
That's a pretty cool trick using the dead center to set up off center work.. Nice one!
Hard to believe someone gave you a thumbs down for this video. Quinn, I never, ever thought to use a center to align a hole for drilling via tailstock. Excellent tip. I have a project coming up using bar stock and this method will improve my accuracy. Thank you and may the person that gave you a thumbs down rethink his/her/its intelligence and agree to trade places so the rest of us can judge their video and rate it. I doubt seriously if it would be more informative.
Now there is two thunb's down. where do these people come from? They must be miserable or perfect in their minds who knows. The video was about basic stuff but if This was around when I started machining on my own it would of saved me alot of misery and time. Quinn does a great job on her videos -- all killer no filler.
@@andyZ3500s Indeed! Some people do not appreciate education. Hence we have the present day democrats in D.C.
Excellent tips, for very small chucks, copper tube offcuts can be used.
Thanks for sharing.
I love the double centre trick. Thank you!
A tip from a 45 year experience machinist: use a wiggler instead of a dead center. Wigglers are spring loaded so the tailstock won't need backing off. Put the indicator tip as close as possible to the work. The farther away the less deflection of the indicator. If you wanna really hold tenths then having the indicator tip 1/2 inch away from the work will not give accurate results. Furthermore, since one end of the wiggler is held in the chuck it won't fall on the cross slide.
All of my 3 jaw chucks are adjustable. If bought that way they are more money than hobbiest folks want to pay. I have modified several of my chucks to make them adjustable. Small chucks can be challenging but I have done 4 inch chucks that work very well. Please let me know if you would like to see how I have done this. I can take some pics. And who doesn't like pictures of metalwork?
Eric
Thank you. Love the centre punch trick
Good stuff. None of us has a shed full of machines and the toys that go with them ,we all have to get the job done with what we have at hand. Anything that makes more use of your lathe is worth knowing.
I wish I could remember all the tricks and tips I've forgotten in the last 35 years... Way to go!
Quinn Thank you and Merry Christmas. I enjoy your videos. Very informative.
I love the 3D printed holder for the indicator...
Quinn another Great video, gets my old mind thinking. Thanks
Thanks much for the info. I've wanted to do copper soft jaws for my lathe and now is a good time to do it. :-)
great tuition, love all your work and videos .
I have used the dead center trick many times and it works great thanks for sharing 👍
Very nice video, even though a lot of these were "obvious" once I saw them, it would have taken me quite some time to figure them out myself standing with the work piece in hand by the lathe. This also very neatly demonstrates why the lathe is the king of machine tools, it's the only machine that can in theory replicate itself.
Bravo! Very nicely done! Thank you!
I once ran a job on a Brown&Sharpe screw machine, about .025 off centre in an off center Hardinge collet. Turned, formed, drilled and tapped. I was new in machinig in an old company, so I thought nothing of it. It took a lot of years before it hit me how many guys would have told me, "Can't be done!"
Very nice work! Definitely an asset to the online tutorial community!
I think I’m falling in love …. With machining 😂
Love your videos, setting up a shop and finding your layout and ideas very useful
The last tip was something I'd not come across in 40 years as a toolmaker, and was pretty nifty to boot. An added bonus to this is that the #tipsblitz19 link brings up some engineering channels I was not aware of so doubly useful. I didn't see a tip from This Old Tony though.
there was one!! hope you saw it.
Fantastic Video!!
Really awesome "stupid" tips here. Very informative, to the point but hilarious at the same time.
Thanks for sharing. Subscribed
I never learned these at school, only when I was working with a toolmaker I learned these. Good work!
Great tricks, and Canadian love too! The full meal deal.
Thanks for sharing Quinn.
Cheers
More great tips! Thanks Quinn!
My dad showed me the dead center trick years ago and it has been a while since I have seen it done by someone else, makes me happy to know someone else does that, works great for making transfer case adapters.
Love your channel. I also like your blog content. I like that you sometimes give some theory as to support your methods. Thank You and Thank You again.
These tips really kept me on my toes!
These tips are pretty cool Quinn! Great video.
Very useful tip on using the dead center for checking runout. Thanks, you earned my subscription 👍
Thanks for the sub!
Thanks for being part of #tipsblitz19. Awesome video!
Loved it! Well done. Thanks
Really great tips. Thanks for taking the time. I have seen copper jaw covers so many times but this is the first time someone is telling how to make 'em.
For the dead center trick, how about using a tap follower to keep the center from falling during the initial eye-ball stage? Edit: Of course someone already came up with that idea : )
Congratulations on project Egress! That accomplishment is forever.
Thank you! It was an honour
They are all good but the last one is fantastic, I will use this a lot thanks for all your hard work
great tips, I had never thought of using a dead center in that manner.
Thanks!
This a actually a treat!
Like your tips. I made a 2nd chuck key for my 4 jaw and found it is somewhat easier to dial in parts using the 2 keys 180 degrees apart. Again thanks.
Awesome just what I was looking for
Thank you, dead center trick will come in handy!
Loved the 4 jaw tricks. Easy when you know how! 😎
Thanks Quinn
Great info thanks for sharing.
Another great video Quinn. I'd love to see "stupid tail stock tricks" at some point in the future especially on your particular lathe. For selfish reasons since my lathe is similar.
Good idea! I’ll see what I can do.
oh thats really nice and clear, as always. the soft jaws are nice. thanks for being a Gem.
Totally useful! I definitely need to get a lathe... and soon
Stephen You do, you REALLY do. Les in UK
Very good! Thank you!
Excellent tips! Thanks.
Nice😃! Really dig that dead center trick. Not stupid whatsoever 😊. Thanks, Quinn😁.
That dead centre trick is excellent - thank you
Great tips! Thank you!
I used that trick with the dead center to make a couple carburetor adapter flanges so the hole would be bored on target (one was offset from center). Definitely making some copper jaw covers for my 4-jaw, but will probably use leftover copper tube (cheaper!) Thanks for sharing!
Thank you I actually learned something 👍
Nice! Your soft jaws are _so_ much nicer and more professional than the ones I just made for the tip blitz.
Great video Quinn, thanks for the upload
Very cool. An easy way to make the copper or brass jaws is to put the material on the jaw and then close the other jaws up tight. Use your favorite tool/hammer to shape it around the jaw.
Quinn! If I could give you three thumbs up I would. Whats interesting is I love playing in my hobby shop and I'm trying to get my wife to do a few things with me. Well you're helping in that area and you just don't realize it. So later on today were going to go out and try a few things together!! WOOOHOOOOO
Yes, quite useful. Thank you.
Alternative: buy a few feet of annealed bare copper wire from the electrical dept of your fav big box store of a size that nestles in the jaw serration. Measure the diameter of your work and cut off a length that will wrap most of the way around. 3 times the diameter is close enough. Make a ring of the wire and slip it over the diameter to be chucked. After a dozen jobs you accumulate enough rings so the need for new ones drops to replacement level.
The beauty of the narrow rings is they allow you to bump the far end of the work so you can dial in the full length very presicely for center driling. The ugly part is if the chucked surface is too smooth the work can slip axially under heavy cuts or drill feeds. The same is true of the design Quinn demonstrated. Axial slip is something to keep in mind unlees the work is blocked or solidly shouldered against movement.
One thing, be sure the copper ring lies in the plane of rotation, preferably in a jaw serration. If it's skewed the part will tend to nutate (wobble so the part axis follows a cone.)
If your four jaw lathe chuck jaws are smooth ie, have no annular serrations, you might consider grinding in at least one shallow groove. Do this in the lathe with the jaws locked on a short slug gripped at the heel. A Dremel or die grinder will do the job. Use a mointed point grinding wheel B-70 if 1/8 shank or A-36 if 1/4 shank. Dress the included angle to 90 degrees symmetrically on the radial plane. Two sets of jaws are handy: one ser smooth, one set serrated
I like the notion of being able to bump the axis true for long (eg shaft) work. I suppose this could also be done with soft steel wire, which would permit of gripping a bit tighter? Hardened C clips from round wire were sometimes used for gudgeon (wrist) pin retention (and can be made by starting to make a spring but changing your mind and cutting it into rings) but I guess these would mark the work, and perhaps not even conform well enough to develop a secure grip?
I knew the four-jaw useful for something other than giving me a heart attack trying to center work in it! That offset drilling trick is great.
Genius, just what I needed, thanks
'Bolt circles on the lathe'
That phrase just saved me having to buy a rotary table. Thank you!
Really nice tips 👍
All great tips! (None were stupid) Thanks for sharing! 👍
good tips, thanks
Wow thank you. Pretty new to machining. Definitely have more lathe than knowledge. Great video
Information well presented. +Thanks +
Best machinning channel ever!
Nice tips, Quinn!
trick # 3 phenominal , i m in r &d for so many years , never thought about that , simply wonderfull
Love it!
The original technique of milling was actually called rotary filing and was done with the cutting tool mounted in the lathe chuck and the work piece mounted on the lathe cross slide.
Great tips. Over the years I've become so machine centric that I've forgotten how versatile the lathe is. Setup is everything and frankly I've become a bit lazy. Well, today was an epithenie! Time to stop and think the work through before committing the tool. Thank you.
A great reminder for me on that same subject was the Project Egress part that I made. I didn’t show a lot of it in the video, but that project was actually about 80% time spent on fixtures and setups. Every operation needed some new work holding trick. Some jobs are like that!
If you use a spring loaded tap follower instead of a dead center you don't have to back off the tailstock when you make your beginning course adjustments...
Fantastic good video
Keep up the good work, great video.
The lathe is quite the amazing mechanical contrivance
The copper jaw thing, I made mine from cheap copper pipe, I cut it lengthwise with a tin snips, then annealed it with a torch. Made it quite easy to work with.
We, the lathe newbies, salute you! Without you and Tony, I wouldn't know what to do with this chunk of metal sitting in my basement, but the more I learn about it, the more I love it.
Tricks within tricks, thanks!!
Hi, the dead center trick is great!
BTW - I saw you struggling on getting the right feeds and speeds on aluminum. Try rubbing alcohol. Any feed / speec will work great. And parts will come out clean.
Nice to see someone using HSS tooling, and also with an appropriate amount of top rake for the material being cut - well done.
Aluminum loves rake. 😉
@@Blondihacks Honestly, it was quite refreshing to see it. It's almost universal that youtuber small shop engineers use totally inappropriate TC tooling to do old fashioned type toolroom stuff. Also, with small fractional horsepower machines, the power required to budge-off metal is much greater than that required to slice it off. I'll keep a watch on your channel. Ciao, T.
Interesting, It all made sense, wasn't sure you could do some of that safely, and the dead center use was genius!
Remember to anneal your copper after a couple of folding operations - will make it much easier to get right folds! Great job!
Not stupid if it works! Great tips :)
Use the live center to press the part up against the jaws using your center punched hole. Lightly snug down your 4 jaws and you have it dialed in pretty close. You can indicate with the dead center after if you need the accuracy. I used that trick to rough in a 4 jaws on existing bores/holes or when I had a center hole already in the part all the time. Usually gets you within a few thou depending on how close your tail stock is and saves time.
Dead center trick is great, not stupid! 👍
