I have been on a quest for the longest time for the most, quietest, silent machine i can build. I have been through many virtual, conceptual builds. Here's my latest idea for a quiet, medium duty, gantry router.
I have on hand a fully functioning K2CNC 14 x 25 gantry frame, a heavy duty 1 h.p. 22k top speed treadmill motor, a variable speed controller, with a speed knob potentiometer, and I was thinking!.
Also, I have on hand a Dremel hand piece, with a 1/8" collet. This has a flexible shaft, what if I mounted it all together? The motor could run the hand piece fastened in a suitable fixture on the Z axis slide and the motor behind the Gantry beam. What issues would this arraignment have? I want to do small plastic parts for my own 1/25th and 1/8th scale scratch building. Part thicknesses no more than 1/8" thick in mostly styrene or proto board foams such as Ren board and the like. What issues would I be likely to encounter with this concept. Comments and constructive suggestions welcome. Thanks
