I need to buy a tool or gauge to draw spiral and ellipse. any info to share? BTW: I bought a gauge from ebay for fibonacci.

The mind boggles: "data mining" ... "spiral" ... whazzup ? You can derive a "golden mean" spiral from the Fibonacci series easily [^].

the neat thing I am looking for is from that Fibonacci gauge: if I fix two needles of it, the third needle is decided. so this can be easily used to do Fibonacci retracement in stock trading. that is in my mind....

Here's how to draw an ellipse[^]. The anchors are at the two focii. As far as a spiral goes, there are various kinds, so you have to more specific. An online search will bring up diagrams and even videos.

The fox knows many things, but the hedgehog knows one big thing.I know how to draw ellipse. but using gauge it is much easier, even quicker than drawing it on screen with computer graphics too :)

Read an interesting take today: fundamentals -> what, technicals -> when & how much.

When I was a kid there was a fantastic drawing kit for this. I think it was called 'sprirograph'. Yep, just looked it up. Spirograph - Wikipedia[^]

Based on the answers one bit of info might be that you should probably define more carefully what sort of "tool" you are actually looking for.
this is the part I am not clear myself. but I did research and find something similar to ellipsograph..

I still have no idea what you are trying to achieve, but, if you want to find some number of equally spaced points on the perimeter of an ellipse, it requires calculus/integration. In my code, I use one of Ramanujan's approximation functions to get satisfactory results for ring/pendant design.

Given the mention of the Fibonacci gauge, I'm assuming you mean 'draw' as in pencil an paper. Depends on how exact you want to be. There are a variety of technical drawing tools that can help like a French curve and a flexible ruler. There are also templates of various sizes that can be used. I think someone already mentioned that two thumb tacks and a loop of string will also give you an ellipse. They can also be constructed with a compass using four compass points constructing each arc independently and joining them. You might want to search for "technical drawing tools" to get a better idea of your options,
