Hey everyone. No I didn’t knurl it. It’s absolutely completely unnecessary on something of this diameter. Knurling where it isn’t absolutely necessary is annoying because it is hard on the fingers and gets dirty. Knurl yours if you like. Me no like. No need to keep commenting on that.
I fully understand that, having cleaned a pound of vintage grime out of 50-70 year old knobs on old electronics. With you know what disgusting stuff in it.
At least denture cleaner helps here..
Looks nice, though. If you never ever touch it, that is.
You so smart! You anticipated my comment, sigh, and it was gonna be [one of] my 1st comment (s).
Great job. Love your channel! Not a machinist, but my grandfather was an engineer with Martin (before Lockheed!) and had a home shop filled with Craftsman™ machines. I wonder how they'd stack up against affordable Asian machines of today. Sadly he passed long before I had even a clue what machining was... sometimes I get a little misty watching you and thinking, "if I only knew then, what I'm learning now. " 😢
Thanks again
Fair play to Precision Matthews for sending the replacement shafts
Do you think they would send such perfect parts to us "normal" people too?
@@seananderson5850I have nothing but praise for Matt and the crew at Precision Matthews. Any time I have had an issue, they were prompt in getting back to me with a fix, whether a part was faulty or something that needed adjustment.
I purchased one of their 12X36 lathes as well as a bench top mill, the model Quinn had before the new one.
I want to say that I really appreciate your putting the “why” into these videos. Even if I never make a crank handle, some day that idea of drilling deeper for a set screw so it can drive with something other than friction will be valuable.
Is it weird that I have never touched a lather or milling machine and still watch every video? Its fun to learn how this stuff is made even if I wont do it myself.
I _hadn't_ ever touched a machine tool until I found this channel. Now I have a small 8x16 lathe, and it's safe to say I learned to use it almost entirely from Quinn's videos 👍
Just last week I hit my first dimensions to within a few hundredths of a millimeter. It feels exactly as good as Quinn makes it look! 😊
Same here!👊
One use at school in 1984 - made a nice aluminium and brass dice/holder - then nothing more. So no, I don’t think it’s weird at all. I’ve watched every episode as well and most times on the day of release.
Me, too. To the best of my knowledge, I’ve never been in the same room of any of this gear at any scale. I am confident that they would recognize me for the cower I am and kill me on sight.
Not weird at all, these are just great videos! I'm on the other end of the spectrum, I do this stuff for a living and I still watch these every Saturday!
I love your subtle sense of humour and your videos. Thanks for the many years of interesting videos
Quinn: can I just say (because we do become accustomed to such good work) THANK YOU - it’s easy to forget how much work goes into these superb, GENEROUS, healing, relaxing, informative, inspiring videos…so I offer you 🌺 and lifelong thanks.❤
Glad you got a handle on the problem.
As Quinn would say: 🤦♀
ISWYDT 😂
Super work!
I love how thin and delicate the narrow end on the spinner sleeve gets, but once its assembled you'd never know it. Beautiful.
I always learn something I can use in my shop from these videos. Since I work on much larger parts and have the room, the shop is filled with good used machines including a Rockwell Mill that is about 2/3 the size of a Bridgeport, highly prized by home machinist. For a small shop those small import machines are the way to go.
Gotta love the ocean sounds setting. I always half-expect to hear a seagull or two whenever I turn mine on.
That was a tricky piece of fault analysis and I struggled initially to picture what the issue was. Excellent video as always and the new fine feed handle is really classy.
Yay! It's Blondihacks time!!!
Your opening reminded me of how I used to talk to myself when I was drinking!😂❤ never could quit until, you know, I quit.
I have it on good authority you can find pristine Bridgeports, Deckels, and Schaublins for bargain basement prices in the aisle over from the unicorn saddles. Free shipping too.
Nice.
It's so cool that you show us how stuff works.
Wow, didn't that sound sophisticated. Oh well.
Hey, did you think about knurling the...
Thanks, and Meow to Sprocket.
I felt that screw drop deep, deep in my soul. When I need one screw I buy or make 4, because I will drop and forever lose at least one, but sometimes two and rarely three of the bastards.
I just consider it to be Metallicor's share of the project. He demands blood and swarf and fasteners and will not be content until He receives what He is owed.
😂👍
Thanks for the lesson in troubleshooting. Being able to identify the root cause of a problem makes it easy to fix (assuming you have the tools).
China's manufacturing skills are amazing, they can build anything you want to any price point. The only reason it's synonymous with "junk" is because the Americans (yes all occupants of north America are Americans in my book) keep coming back and asking "okay, but can you make it even cheaper??" They build what's asked of them. They can make water OR wine, but they can't turn water INTO wine.
Should have left it right there. 😂😂😂
Turned out awesome 👌😊
I talked to my doctor about the runout in my shaft. He assured me it's very common and nothing to worry about.
Big Thanks for all tips. I wait for this moment every week...... Keep the 3D drawing in the upper corner, good for understand the movement (EMCO unimat 3) Gratings from Sweden.
We're in a beautiful point in time where companies are making tools for non-professionals, even down to small equipment We're not forced to buy the tool that would last years for someone using it day in day out, but instead budget items for folks who would use it intermittently, that'll last years in their hands too!
That is SWEET! I am definitely copying that for my 728. Thanks!
Nice new knob for the fine adjust feature Quin. I think it needs diamond knurling on the outer edge to make it really classy. 🙂🙂🙂
My thoughts exactly, I kept watching, thinking she would knurl that edge.
Not needed and I hate knurling when it isn’t needed
Excellent work, as usual.
Doubling up set screws is fairly common in manufacturing as well. After you've been called out to the same machine 6 times in one night because the infeed table height hand wheel came off you'll throw a second set screw behind it so your radio finally shuts up for 5 minutes.
Love your work Quinn 💙🇺🇸👍
Love that handle, makes the mill look twice as fancy ;)
Regarding Chinese stuff:
I lately almost exclusive get that stuff for electronic test and measurement equipment, also at work .. for exactly the same reason. For what that stuff costs, it is plain and simply amazing. Yes, the software and UI tend to be a little bit clunky and not quite as polished than the big western brands .. but they cost a third or even less. And many of the features that are options with the big name brands and tend to double the price are included in the base package. And yes, people using 100k equipment (they didn't pay for, of course) give me a bad time about it.
Those brands have learned though .. they now sometimes sell the same thing, with their label stuck to it. I obviously won't name any company here, but anyone who is even remotely in the business knows which brands I'm referring to.
Excellent content and explanations.
The cheap Asian made machinery has been amazing for the hobbyist, before these machines were available the model engineer normally had to do all their milling on the lathe which would normally be a Myford, Southbend or similar machine and they would usually have had to build most of the tooling as well as there was relatively little available and it was expensive.
Currently its a great time to be a home based machinist, we have the Internet for spreading knowledge and information quickly and easily, cost effective imported machinery and tooling, cheap used industrial machinery because of the decline of industry and its move to almost all CNC based.
Cheap milling machines have been around since the late 70's/early 80's at least. I have one from then, many people do. A company called Rong Fu builds them in various guises, RF25, RF30 etc, actually pretty good machines and one my Father acquired for model engineering himself. I believe you can pick up an RF25 nowadays for less than £2k or thereabouts new. Not quite as large as Quinn's, but the table on mine is deeper in the Y axis so allows for more flexibility in hold down options on larger parts like road wheels for traction engines and steam rollers etc. I know these weren't particularly expensive machines to buy new as lots were used in colleges in the 80's and 90's as training machines which is where he got his from (and worked at teaching people how to use them.) I don't mean to be contrary to you for the sake of it, my point is that although they were available the internet has made them far more accessible to a much greater extent to many more people that otherwise would not have had access to, or knowledge of, them and that can only be a good thing for all of us... but they were out there. lol
For me the frustration of the oriental kit is that often they have made such a good job, to stumble on the last like bit is just a shame.
Nice fix Quin. I have big brother to this mill. It has the same head, but with the knee instead of the column adjustment. I will be looking out for these issues.
12:46 * Giggling reaches panic levels *
Giggling aside, another thing the import machines give is standardization; accessories that fit many machines makes for better price and selection for them.
16:30 I cant wait for the new 2025 aluminium next year 🙃
Thank you 🥺
ABOM MENTIONED!!!!!!!!
People underestimate how much stuff cost to make when they look at used machines. For example a Deckel S1 grinder which people say about that it is built extremely sturdy for what it does cost about as much in the 60s as one to one and a half single family homes.
I now know what a Dutch Angle is. I have a few Dutch friends, who make fun of me (and the English in general) for drinking tea with milk in it, so I now have another weapon in my arsenal for winding them up in retaliation. Alongside going Dutch, Dutch Courage, Dutch agreement, etc.
16:56 Satisfiying pop. 😀
“I’m tempted to leave it right here” gave me horror movie vibes every time you said it.
24:21 early 2000's Yamaha sound pad effects!
Instead of the spinning wings of death, could you have made a fixture, or bored the work and then completed the rest of the turning on a mandrel? Those spinning jaws scare the 💩 out of me on the rare occasions I use my 90 year old 9" South Bend.
Re: your comments on modern hobbyist machines - My old 415-Y South Bend may be the 1934 equivalent of today's hobby lathe. It was $94 USD back in 1934 which calculates out to about $2200 today. It was/is very rudimentary compared to the bells and whistles on todays lathes, but IMO it was more precisely and carefully made and still does good work within its limitations. I also have a '50s-'60s Benchmaster mill, and I'd dearly love to have a mill like yours! (I'd keep the Benchmaster though!)
I know it's a lot of work putting these together for us, and I sincerely appreciate your high-quality videos.
Maybe a splash of orange marker/paint stick on the spinning wings?
But but but Quinn!!! We need to be browbeating everyone who doesnt have a 20000 dollar 1960s bridgeport and a shop big enough to fit it! If we aren't grouchy and hostile towards newcomers, how will anyone know how cool we are??
Personally I like it when people do that, now you know really quickly who to avoid 🤣 Seriously though, if you have the space and the drive to restore an old machine it can be a cool project to start with old iron, I like the way Inheritance Machine has shown his restoration projects, but I know I don't have the room or time to restore old iron, small import to make parts today for the win, now I just need a garage and a small import tool for projects.
How about powder coating the wheel? Nice job , also good on PM for sending the parts !
Yes, thank you for doing this! I love my 728, but the fine feed stinks.
I hope that you don't delete this comment. It is satisfying watching aluminum being milled. Great job on that adjustment wheel, it looks like it came that way. I love you.❤❤❤❤😊
You might have better luck with your comments not being deleted if you don't tell people on the internet you love them...
Knurling? Maybe Knurling on the outside of the aluminum part of the knob would be an additional benefit.
Not necessary
I was considering making a wheel for the fine feed of my own mini mill which currently uses an Allen key. Often quite awkward.
Looks great! But why did you omit some kind of jimping on the out side of the wheel? Time investment? Mechanical reason? Preference?
Not needed
Nice job. I agree with you. If you sink that kind of money into a Bridgeport (or any other brand), you really are going to want to make money with it. That moves it away from being a hobby.
That knob could have been about 8" in diameter and made of transparent material. 😊
1:30 * Juvenile giggling intensifies *
How about putting a thick felt washer behind the new knob to remove the play in the shaft...
Wrong axis of play
You could add hex on center of new handle to move it with poor man's power feed
Looking good, however I was sure you would knurl that knob!
Same.
Not needed
Quinn, do you have any recommendations for a Sensitive Drilling attachment on the Precision Matthews? I need to drill some really accurate laid out #80 holes so the dro is really helpful.
Honestly I find it isn’t necessary. I drill a lot of 0-80 holes and because the mill is so small, it has plenty of feel in the quill for small drills.
@@Blondihacks Thank you!
Hi, maybe a straight knurl on the outside might be nice. 😁
Not needed
Superblondie, this time you copied me telepathically 😂 I made it two years ago on my bf 20, very convenient.😉😋🤗
damn youtube keeps restarting... wait...
I'm tempted to leave this comment right here
That particular comment of the deletion variety is sadly common in other hobbies as well. It was super common when I was heavily into air rifles and pistols. "It's not German! It's not British! It's Asian junk and you guys turning them into awesome things are just stupid!" Blah, Blah, Blah. In retrospect, that hobby introduced me to hobby machining and maybe it is just machinists who are responsible?
I think the issue with Chinese stuff isn't that it's all cheap cr*p, it's that they will make you whatever you want and will pay for. Mostly we want cheap stuff so they, mostly, make the low-quality things that we love. It's our fault.
Of course, if you want really high quality, you're then fighting the law of diminishing returns, and you're at risk of being sold a fake. At least PM seems to be a half-decent company -when it comes to dealing with Quinn, anyway.
3:35 🤣
kind of expected you to knurl the outer rim to improve finger grip..
Not needed and I don’t like knurling unless it’s absolutely necessary
Cumulative of errors
i think professionals often underestimate the amount of bullshit hobbyists are willing to put up with to be able to do cool things on a small budget
2nd. Lol.
I'm the first to comment 🎉🎉
Good video Blondihacks
