Hi there,
This is Bogdan from Romania.
I'm a mechanical engineer - specialized in the industrial robotic field, 3D designer, industrial designer and, 3D modeler.
For some of my projects, I'm also doing the physical prototype too.
I'm doing product design, industrial design, reverse engineering, ideation, etc.
I have over 15 years of experience working on various systems/devices across multiple industries, from concept to launch.
1 - you will need to press the pile of paper in order to avoid ripping off of the upper layer(s)
2 - will be necessary to have one shaft which to drive all the drill bits at once (this is the real challenge) - and the solution with a single belt is not quite workable as the center axis of the bits is only 0.185"...
3 - would be useful to see more drawings/sketches
btw - there is a discrepancy between said center axis - 0.185" and the dimensions in the pdf - 0.197"... :(
For any more questions, we could chat here, including the whole details of the project, final price, time frame, deliverables, etc, etc...
Regards
Bogdan
