Hi I've been reading the forum for a while and also some of CNC zone..
I've found some really helpfull info especially on the flex of the Sieg X2 column on here.

I had no metal working experiance and wanted to make some lights for mountain biking, so i went to my local Axminster tools and came away with a Sieg SX2.

The SX2 comes with the belt drive conversion, 500w brushless motor and varible speed control.

The first mod i did was to add DRO's to my X and Y axis, please ignore the vice in the pics below. That was one of my first buying mistakes, I now use a 3 inch precision tools maker vice as in the pic above.

Here's some of the lights that I've made so far

Thanks

Welcome GD - very tidy job on the lights!

Been there, seen that.
My 3" toolmaker vice came without side slots, too, and was 'temporarily' mounted on the mill like Your is. Five or six years later I finally got around machining some proper clamps to fit the holes on the sides. It took no more than half an hour of work: I wonder why I waited so long.

Nice work on the lights, GD. Are those LED or incandescent? wEc1

Cheers Guys, Rudy..
All my lights are led.. The ones with tripple leds have batttery monitoring and thermal protection. So if the light gets to hot it will drop it to a lower level.
Here's how bright the top one is..

So where do we get details and circuitry for those lights then?

 

[Goldigger]

Here's where I get the circuit boards.. George had different boards, you just pick the one that is suited to the max drive current for your leds. Choose a buck driver if your battery pack has a higher voltage than what the leds forward voltage is.
Boost driver if your battery has less voltage than the vf of the leds

So in one of my lights I used cree xml leds which have a vf of about 3.3volts and a max drive current of 3amps. My battery pack is a RC lipo pack 14.8v 5800mah.
So I used the H6flex driver as it allows me to set my max current to 3 amps and reduces the voltage to the correct vf of the leds

The two small lights use 3 up xpg boards from here, there leds engines - driver and leds combined

Anyway maybe you know all this already..

Those lights are better than my car lights ;D
Thanks for sharing.
