Your smaller machined part ;)

This is mine: tyre's valvle.



Would be cool post also the bigger one!!!

Beautiful work G. You've really got your head around that lathe. Are you making more than one of them?!

Not my work (I've stolen the picture from Thunder Valley F1) but check out those nut and bolt heads on the sidecases at the back of the photo!



I know that they're CNC'ed but how do they make large quantites of them at a time? I can't imagine working that small by hand!

Cool Gio, how do you do that without it breaking off? This is one of the things I am struggling with at the moment. I find when I get under 1mm it breaks off.

I got the same problem until now: I guess some helps would be:

- you see that the thiny bit has a "big foot" with bigger diameters, this I guess help to contain if not prevents vibrations, my thought is that the minor diam. collapse for vibrations, but react well at longitudinal forces

- a perfect tuning of the cutter tool heigh: it must be exactly at the rod's center/axis

- since a thini diam can't afford a big force I used a 45° tool's bit, so it touch the alu in 1 only point

later I'll post some job's step, I seen you'll cut very thin diam (0.2 mm?) but not so long... I'm working on those factor since I need 6-8mm long wires (turned, comples form) by 0.2 mm diam to do....... wire spoked rims
