@@hedning003 Heh, I'm subscribed to both, and look forward to both channel's videos every week. It seems that good content is getting harder and harder to come by these days. I'm subscribed to a LOT of channels, but often find myself scrolling through the subscription feed not finding much of value to watch anymore. This (and rustinox) are one of very few channels that every video is "must watch" and never disappoints!
Better CNC lathes do come up for cheap, or even free somewhat regularly these days. The mid to late 90's machines, which actually have really nice controls, and are fairly easy to 'modernize' with DNC boxes with USB are getting to the age where the controls are starting to fail, and in a lot of cases, the owner will replace the whole machine rather than fix the old one. If you're handy with a multimeter and a soldering iron, they can usually be fixed for a couple hundred dollars in parts (or sometimes way less). Or you can always go the retrofit route, but 90's controllers are good enough to just fix and keep using.
Nice work there mate. I'm impressed at just how well the mini performed tbh. Some think Whitworth is a funny, obscure, standard, but the truth is, Mr Whitworth was the founder of thread standards. Yay! Keep the reggae coming too.
This is a truly great video idea. No one else has done this AFAIK. Most people have no idea of all the differences. Similar to comparing a child's kite with a Saturn 5 rocket.
He should've used the same inserts in both to better compare the surface finish differences, but yes, very great video overall! I don't think many people have a completely re-built to better than factory and CNC'd mini lathe to compare to a completely retrofitted Schaublin. This is pretty rarefied-air content here, and I'm all about it!
That's a pretty realistic comparison. I understand the dislike for the mini-lathe, I'm squarely in that camp, but you can't deny it has capabilities and is far superior than no-lathe!
congrats on 30k man.. i dont think you had alot when we started talking--- well deserved! and that shaublin is a amazing build machine! i am sure you will make it shine with more use
Raise your hand if you thought the Do-All bandsaw fell out of gear at 13:09? Hooray that it didn't! I would find a way to mount the spare screw to the Clarkson grinder, after all that effort, Murphy will come and you'll wish you knew where it was. One might jokingly suggest making a 1/2-12 BSW tap to thread it into a random hole (… … …), but just a little bit of wood or thin aluminum next to the control box or inside the pedestal is how I'd go.
could probably just move the clarkson off the base a little, and chuck the extra screw into the stand - that way you'll always know where it is when you never end up needing it :)
Ooh, you tweaked my conscience, so I've finally subscribed! If only I had such a short to do list on my Clarkson. It was an auction score earlier this year, came complete with all the accessories. Currently its sat in my garage awaiting a full restoration, plus me learning how to use it. I currently use a little Union tool and cutter grinder. There's only room for one in the workshop!
Sir Joseph Whitworth does not have the enormous reputation he deserves. The three plate method? That was him. This man essentialluy invented precision, and those who know about his screw threads mostly deride them. Hes my personal hero.
Not to nitpick, but the three plate method wasn't invented by him but popularized it. He deserves recognition for spreading these ideas and standardizing alot of stuff during the time of the industrial revolution, but the three plate method was known since atleast before Newton, when he polished glass plates to be opticaly flat. However, Whitworth greatly sped up the process of making surface plates by introducing spotting and scraping. Even then, it's debatable if he or Maudslay really invented it.
Very interesting comparison. I tought the difference would be bigger... For the drawing boards: It's been over 20 years now, but back in vocational school we used to use boards from Faber-Castel over Rotring. The quality was way better. But I don't know the situation today. I use mine too til today. Not as often, cause of CAD, but for small, fast drawings it's a nice little tool.
1 thing that would help the mini lathe, flood cooling and positive rake hss indexable inserts. Otomh probably cut the cutting force by 30-40%. It'll obviously take longer make same cuts but would increase accuracy a fair bit
The choice between no lathe and the mini lathe really is a no brainer. I hate to make *that* suggestion, but you either need more "gronk" on the chuck(s) or the soft jaws need to come back... Either way, the slipping from those heavier cuts seems... Too easy. If the scroll is really really stiff to turn when the chucks are apart, it might be smart to somehow wear or lap the chucks movement in.
way too easy. just from looking at it i can tell he's barely tightening those chucks. the ER40 can be tightened to 150 Nm, mark is definitely not applying that kind of torque with a 20 cm lever arm
Not gonna lie. Did a small jiggle when I saw the part move in the chuck. Kinda reminded me of one of my classmates when we did our exam. The pressure was suppose to be 30 on the chuck but it was at 2 ( cause the day before he had turned it down for some light finish turning on a thin wall test part and forgot to turn it back up ) luckily it only costed him like 4 min of his exam time and nothing else
Thanks for the great video, I was convinced one bolt would replace the hex bolt on the other side so they could match, guess it’s not in the spirit of the Clarkson to have matching fasteners 😂
Never grind carbide off the edge (as you did at 17:36) It's so hard and brittle, that it will microchip at the edge. No matter how fine the stone is. Always do this in to the edge.
Good video Mark. I rekon you need a longer t handel on that 3 jaw chuck key. Just so you can crank it a bit more on solid bar stock. On the cnc controller you have a great funky music button. Or maybe you do it in edit. Thanks for sharing
Honestly I was thinking of minilathe recently, since guys at work look for something bigger from Bernardo and some minilathe with their branding appeared in search results. I wonder what quality could it be - I mean, for sure it looks like any other minilathe from China, but at least that one does have metal gears and probably might have some better bearings? They make it sound like frame is standard, with mechanical parts which are important are replaced with better ones, but who knows.
It’s more common to find BSP or BSPT threading inserts than Whitworth on occasions. All are 55 degree Whitworth thread forms. Although, for me, even hand grinding a Whitworth HSS tool is somehow easier than a metric or SAE tool. Must have been all the time as an apprentice make fasteners for fine British machinery and vehicles. Take care n play safe.
Cool comparison. Why not use the tailstock on the mini-lathe like you did with the Schaublin when turning the shank section of the bolt? Also, without it during threading there would possibly be some deflection of the mini-lathe and possibly why the mini-lathe bolt wouldn't thread in.
If the height on the other side isn't an issue, why not use your other bolt on that side so you have all the same? (Sorry if you mentioned it in the video, house is pretty loud, was partially distracted for a bit.
I didn't think about that. Generally, Clarkson used a different sized fastener at every joint, so you already need every tool you have to do anything with it :)
Long time subscriber here. Was shocked to see 30k subscribers, should be 10 multiple of that at minimum.
Thanks your your kind words. Please send a link to your ten :)
i agree - weard that this channel as well as Michel:s rustinox dont have more subscribers

Today i learned that the channel owner can see per-user statistics. Neat.
Nah, I just made that up , good probability that there is a some Michael in Germany, and Peter in Calif who will feel the heat though :)
google is actually quite aggressive about preventing you from slicing reported dimensions fine enough to get individual statistics :)
@@RotarySMP 😂😂😂😂😂
Something I like here I the music too - like your intro
I have a soft spot for reggae :)
Oh boy Mark, I was beginning to worry my Sunday was lost. But it isn't!
Hi Willem, sorry I got distracted this weekend :)
I would also choose the mini lathe. Just like anyone else that didn't win the lottery this week.
And with that, you just passed 30K subs.

That drawing board brings back (Fond?) memories of "Tech Drawing" classes in High School :)
Holding up an imperial tape measure and reading it off in millimeters is next level trolling. I'm oscillating between "impressed" and "triggered".
Calling Standard Imperial is some next level trolling. I'm not impressed.
Nice work there mate. I'm impressed at just how well the mini performed tbh.
Some think Whitworth is a funny, obscure, standard, but the truth is, Mr Whitworth was the founder of thread standards.

The little "polished turd" does a splendid job.

@@gorak9000 Agree!
almost without fail whenever I visit this channel, I start looking for a tool and cutter grinder to buy after watching the video
They are a fun way to waste a lot of time :)
@RotarySMP They just seem to elude me, either too far away or too expensive or both...
@@HeimoVN This one kind of fell into my hands as my mate bought that TOS, I did a video on, and so I made him and offer on this one.

Surprising comparison, actually. 👍 I quite enjoyed the soundtrack of the split screen segments!
Thanks for the comparison video. I'm surprised the mini did as well as it did. Looks like you solidified it well!
Great to see the mini lathe in action again!

I'd gladly take the mini lathe off your hands!
Just got back from Florida an had to leave lots of stuff...
but, three suitcases full of what I could!
Slipping chucks and vises seem to be a recurring theme chez SMP. Sounds like the perfect justification for a small torque wrench for Xmas!
Good video RotarySMP

It is interesting that this very nice chuck doesn't grip so well on this half hard, ground rod.
Great video as always Mark and _Congrats on 30k Sub_ you deserve it! Also thanks for the link to the Drafting Pad and I'm loving the Reggae Music. 👍👍
I enjoyed the presentation. Thanks.

It's so hard and brittle, that it will microchip at the edge. No matter how fine the stone is.
Always do this in to the edge.
The steel is probably 42crmo4 whit the comercial QT . I don’t remember exactly but 42crmo4 (4140) that I have always in stock.
Hi Emil, thanks for that. It is really easy to get a fantastic finish on it.
Say hi to Vasi when you see him. It was really nice to meet him.

Thank you for a very interesting film!
I thought you were not uploading today,panic over😂.
Hi Ken, sorry about the delay.
Hey mate, just wondering why did you program the contour like you did and not in one pass (not when roughing)
I didn't use CAM. I just used the LinuxCNC lathe macros to cut each step.

Huh, I figured you were going to replace that hex head bolt so they all matched.
great work thanks for the video
I think those bolts were missing some airplane facts

Just a joke, but I statisically there is a Michael in Germany, and a Peter in Calif, who will feel the heat :)
Whitworth threads; for a long time I thought that was something like the Yeti or Loch Ness monster..
ive never seen a 1/2in 12 tpi thread before, ase would be 1/2in 13 tpi thread
Yeah, 1/2 UNC is 13TPI; and 1/2 BSW is 12 TPI. Weird thread system :)
Love Schaublin :)
They make wonderful machines.
Have you tried an ultrasonic toothbrush and solvents on the nameplate?
is that the turd "we" polished ? looks amazing. thought we wouldn't get a video today, nice.
Still haven’t finished cleaning that nameplate …… project not complete.
Anyone else notice he didn't use tailstock support on the mini lathe 🙄
Making a bolt with two different CNC lathes 😂
that was lucky :) first here
Hi Luke, good timing. :)
@@RotarySMP No kidding was only up for a few seconds. The mini lathe doesn't seem too bad for what it is
@@LCalleja I am not sure I did the Schaublin justice here. It is a way better lathe than the 7x12.
@@RotarySMPI can imagine there is a huge difference between them but at least the mini lathe is usable :/
Tighten all 3 of the square drive holes in the chuck and go around twice,
Every lathe is a swiss type lathe with enough coaxial pressure!
Watching almost every video, but this time ... i even had to write a comment. Maybe thighten every chuck more. It´s consitent to loose
Are you an engineer in your proffesional job? I wish I had all that expertise....
the inserts look different...
Subscription police. Isn't that a bit Orwellian?
