Found a nice one from the headstock end. And even with a 6 mm wire sticking out the chuck it can become bad quickly. Amazing, considering that such a machine probably weighs a bit or more! .... When you think "I probably should not do this!" then don't.

Not the point! All they might be after is a list of 2000+ fools and their shipping addresses, launching the next more elaborated scam (or just doing tailored fool specific advertisement). Using $$$pal :cool: :cool: is probably a honey trap for data theft anyway (different story). Just because I...

Yes, valid reminder! Not careful it whips and is gone into the chip tray. (if the unsupported part is big enough maybe it gets even dangerous) To avoid whiping the skinny end could be fed into a tube that is held by the drill chuck in the tailstock.

Maybe they are simply after your E-mail address and shipping address they can sell those for a dollar or two. If you never receive anything, what are you going to do. Hire some lawyer to chase down 60 USD? So everyone who bothers with a 60 USD mini lathe, is highly probably an easy victim to...

Is there a risk, that soft steel becomes a cork screw if a long piece is driven from the chuck end? I ruined some dies, when trying to thread the end of a skinny soft rod. Does a Swiss lathe re-chuck the work on the driven side? I had to make a long skinny piece a while ago, so I purchased a...

Ah now I get it. The pendulum is not making the signal, it is just rotating the other disk. I thought you needed also some display. The Stepper solution is very handy for doing things automatic or semi automatic. :)

Questions: Do you want to use it in two or one orientation? Parallel to the X or Y table as A or B axis the pendulum thing would work. If you want to use it flat as C axis not so much. required accuracy, 5000 line encoder good enough? Indirect reading with the encoder on the hand...

Why would a vetenerian need CAD? For the cat? (pun) p.s. oops the spelling got a little out of hand. (F+)

At work we use FreeCad (for the occasional simple part, then ordered from outside maker). It is quite good at opening files to just look at. (never had issues with looking at customer files) Private I use a paid software, that would have been "free" initially, beforer they dumbed it down to a...

I just have some of these in mind. I guess they cannot cost more than 1 or 2 stellar bucks. Happy programming. :cool: There seems to be never a video where a real part is made. I guess, because all we could see, is coolant mist or oil fumes.

For small parts you could use a small vise upside down. Then after clamping the small vise goes into the bigger one. I hope one can get the idea from my quick sketch. Ofcourse the angle is reversed 90° - x. Greetings Timo

Just so that I understand, you work in a museum that makes parts for historic race cars? :cool:

Yes scanning is similar to the photo method and these proposals give new ideas. The scanner has something like 2400 dpi, I should try to find one of those microscope rulers. But .... a typical gear cutter is difficult to put perpendicular on a copy machine 🥹 The angled tip makes it difficult...

Small gear rack. Who can spot the indexing mistake? Naturally last pass, :-/ but at least on the end of the rack :cool: The indexing was quite tedious. (even with DRO)

I see where this is going and it makes sense. I was thinking for measuring a disc cutter from the side taking a photo might become difficult. After first experiments, I realized that measuring the tip is probably my least problem :cool:. I realized that I do not need to measure the tool. A...
