Great shop project, thanks for. Sharing with us. Loved the out takes.
Great project! Really sparking some ideas for me.
Very talented machinist! You definitely know your way around the shop. And I approve of any criticism you throw at us crazy Americans.
This was very inspiring and get many people thinking. Thanks for sharing your thoughts and progress. 🇺🇸 🍻 🇩🇪
Thank you. You probably refer to metric vs. imperial: no criticism intended at all. People just like to use what they are used to use (3 x "use" :-) ) The size of the base unit doesn't really matter. The main advantage of the metric system is that all derived units are multiples of 10 (e.g. 1 km = 10*10*10 m). Thia makes conversions so easy.
In the machining world expressing thread pitches in threads per inch is advantageous in comparison to what is usually used in the metric world (mm per thread revolution): thread dials work much better (no special gears required) with the TPI system. (Of course you could do the same in the metric system, i.e. expressing thread pitches in TPM (threads per meter)).
@@HaraldFinster no,no, I was only joking my friend. By criticism I just meant you can offer critique and it would be a valuable insight that one should see as a good thing. I was not at all trying to offend you or the metric system. I was only kidding. There is nothing wrong with the metric system. It’s an ongoing poking fun back and forth between us that’s all.
Sorry to offend you. My machines are both metric and imperial and it often comes with some poking fun at me when I share some of my experiences and operations.
This is the first time I’ve seen your content and I was just trying to make a little joke and support your channel by leaving a comment. No ill intentions harbored my dear friend.
@@jasonhull5712 Hi, no worries - I didn't feel offended at all. Thanks for your kind comment. I agree: there isn't anything wrong with either system, meters, inches or bananas (the latter seems to be the favourite measuring unit of my favourite Australien machinist (CEE) 🙂 )
How does it hold up against the stick slip effect? I had the much simpler idea of moving the table against a piece of wood thats stuck between the table and the floor. Someone said its more effective to tap the table as to overcome the friction little by little, rather than create tension/compression force of a screw or piece of wood... what are your thoughts on that?
Until now I just tried to adjust the table with the 1/100th mm (1/2 thou) indicator and it was pretty easy to hit the desired value.
I used the device in such a way that the table was lifted. Thus gravity helped to keep the mechanism under slight tension/pressure and eliminates and play/backlash in the mechanism.
Thanks for the idea.my first thought,this device represents a lot of care and hard work. My second was how would I do this? My mill has a fixed table, but the head can be rotated and angles set from an enormous protractor scale on the head, but fine adjustment with a strut operated by raising the X would be perfect. Excellent.
Just tried to adjust the table using a digital dial gauge with a 1µm resolution and I am pleased to tell that I was able to adjust the table within plus/minus 1 µm. (about 1/2 ten thousands of an inch)
Hey I think your calipers are broken.. they are reading funny looking numbers.. 😮😊😆
Why bother making your videos in German. English is a Germanic language. 😂
The German version was on special request of a friend :-) and there is a quite large German speaking community ("zerspanungsbude")
@@bobweiram6321 I’m grateful he does an English version, my German is dreadful, mercifully most technologists in Germany have at least some German. I once had to do a corrosion lecture in Germany, the lab was packed with factory staff some of whom had less English. The laughter was genuine as we all stumbled to an understanding of the evil nature of the chloride ion!
