Hi Folks,
once again, all my current projects came to a stop, because I wanted to build a tool (to build other tools, that will build other tools, ...you know the drill )
This time its Jerry Howells Highspeed Spindle:
http://www.model-engine-plans.com/engineplans/bookshelf/millspindle.htm?47,17
I ordered the plans, and started building...this is the result:
I modified the design to accept the small steel collets from the Proxxon Micro-Powertools (Almost like the Dremel ones, but made of hardened steel and ground)
Fits into a 20mm collet, the motor is a cheap size 540 Type, but I am looking for a DC Servo with a bit more grunt.
Tested it with an ATX Pc powersupply, works great for engraving and endmills smaller 2mm.
Here a short video (bit blurry):

And the result:
(If you wonder, "CNC-Ecke" (cnc-corner) is a german forum about cnc/manual machining...)
greetings
Stefan
