Sure glad t see you're coming out with more videos, you're likely my favorite machining KZbin channel. Appreciate the knowledge you pass on!

[@strykerentllc]

The level of detailed explanation and instruction Stefan goes to in every one of his videos is nothing short of excellent.

[@qualified_monkey8813]

I really liked the subtle welcome message bite into another well known KZbinr machinist 😇

[@risfutile]

He's become quite the advertisement channel... 🙁 Loved the older stuff where he made large machinery replacement parts, his own tooling or any fabrication really. He has a great work ethic and does things one way and only one way: the right way. But it's just become too rare that he applies his skills to meaningful work. I'm not wishing him unwell. It's his channel and it's cool he gets endorsements. It's just not for me anymore. Really digging Cutting Edge Engineering Australia though!

[@Deebo1812]

He wasn’t referring to Abom.. it was Adamthemachinist I heard.. Unless I missed it which is distinctly possible..

[@kundeleczek1]

[@larryw5329]

Oh be nice. Even Stephen has shown home improvements (yet he kept it captivating) but he hasn't monetized his RV and bbq.

[@davesmith9325]

@@larryw5329 why be nice ? At Abom's level, youtube isn't just sharing your passion its a nice revenue stream. Maybe that's the root of the problem, the money changes priorities for some creators. But philosophy aside : Abom isn't providing his content as a charity, he is trading our time for his revenue. Padding out the slightest thing over several videos is just wasting our time. And when the interesting machining content drops too low .. we should just stop watching. Stefans joke at the start "blah blah..not really this is a machining channel" hits the bullseye. That's why people interested in machining hang on every word from Stefan and lost interest in Abom. .. .. Plus of course Stefan is also one of the most skilled craftsmen out there (none of us should try to choose between Stefan & Robin) .. we learn SO much just listening to their calm elaborations of what and why. This is what we came for. Distilled wisdom. THANK YOU FOR SHARING STEFAN.

[@bkoholliston]

The micro-machining was fun! Also to those who don't like using the carriage to drill, ream, tap, die cut, etc.--how to they think it works on a CNC lathe? That worm-drive chuck and floating reamer holder are made for the CNC lathe world. Some people are just stuck in the past I guess. I always enjoy your channel--so good.

[@Gottenhimfella]

Anyone who wants to exceed the usual drill chuck grip without shelling out for a CNC worm drive chuck could consider a second-hand Jacobs Ball bearing Super Chuck. I regularly power tap up to M16 in stainless and occasionally M20 with my 3/4" capacity one of these, and it has never slipped. Nor broken a tap, because I made up a passive (ie free spinning) spindle which plugs into the (Morse #5) tailstock taper, which I can prevent from rotating using the steering wheel off a go-kart (quite big diameter), which I can easily hand hold at opposite places on the grippy rim, but allow to slip the moment the tap binds or bottoms out. (Like an extreme 4WDer, I never put my thumbs through, as the spokes might remove them.) When I engage the reverse clutch of the headstock drive, I can also hand spin the tap to rapid retract. It works better than I hoped and probably better than anyone reading this would imagine.

[@albertmagician8613]

I had a drill press where the Jacobs drill holder was dropping out constantly . The easy fix was to run the press while holding the Jaobs and a litle bit of grinding paste. It has never fallen out since.

[@georgewocosky]

Excellent ! * When machining , excellence should be the aim ;) ( Stefan is absolutely one of the best YT channels to watch for gaining practical knowledge of this fine art ! ) Add me to the list of those who love your long format videos - the mixture of processes is extremely well presented !

A previous owner of my Bridgeport clone somehow managed to sheer off the drive pin and i've been running it for years with no drive pin, i often do very heavy cuts and i've never had any problems with it spinning the r8 in the spindle

[@Steve_Just_Steve]

A series 1 Bridgeport with an R8 taper? I didn't think they had a drive pin, but an alignment pin.

[@Steve_Just_Steve]

@xman charl It's not a "drive" pin, it's an alignment pin not a drive dog/pin. Series 1 don't have a drive pin. I have a Series 2 with 40 taper spindle, it's has drive dogs.

[@MachiningandMicrowaves]

Previous owner sheared the pin off in mine. I fitted a new one. Nice easy job. Whether it does anything useful I rather doubt.

[@markshort9098]

If i remember right we used dykem applied @ like .0005" to .001" and permatex @ .001-.0015.... depending on the seal angle among other features like torque make up on threaded connections and shit. I know it's another world but everything has its place. We had bluing blocks that were nothing but gage blocks with different finishes or micro steps across one plane which u then applied a dab of either bluing and swiping it with a matching block that came together with the bluing blocks as a set revealed the ideal/proper display of how the correct thickness visually looks after being applied correctly.

I use one of the Andonstar "microscope" camera things for making parts around 1.5 mm diameter on my old Colchester 1800,, but I miss the 3D view of the optical binocular scope I use for electronic component assembly. After seeing yours, I'm tempted to get a cheap Amscope binocular scope with a 0.5x lens extender and make a mount for the lathe.

[@StefanGotteswinter]

Yeah, I was thinking about getting a cheap optical microscope for beeing used on the machines, the Leica is a bit expensive in case of a crash event.. :D

Blimey this guy is resourceful!!!. Makes me feel quite incompetant.

[@FinnoUgricMachining]

Stefan, thanks for another very good presentation on precision techniques. Squeezing down to essentials is a form of art. One thing that made me think over Your setup. How did You initially ensure that the flange of that ISO holder was concentric with the ISO taper? It does not need to be. I quess that in that case it was concentric as the taper was running true when You turned it around. I have done some ISO 30 tapers myself and I always "turn" the tool attaching surfaces in the milling machine to be sure that they become parallel/perpendicular. P.S. You need a hair cut 😀 Edit: Ahhh ... already done it seems. Edit #2: Man ... it seems to be back so ...

[@Gottenhimfella]

Anyone watching who has a more badly galled or worn taper than we see here, in an otherwise good machine, might consider hard chroming as a way to regain size. I just had this done to the outside diameter of a worn and pitted lathe tailstock barrel (the taper was fine). It is quite a big diameter, about 65 mm dia (Morse Taper #5 inside) maybe 400 long, and it only cost the equivalent of about USD200 including grinding to size, so merely building up such a small taper should be only a few tens of dollars,
