Concern about the equal consumption of filaments as a tow is being wound.

The spool may have to rotate at the same rpm as the A-axis (at least for the torque tube and possibly other tapered items). This requirement would be the result of the fact that some of the tow's filaments are being laid down at a slightly different rate as other in the same tow (same problem with width as trying to lay unidirectional tape on a tapered mandrel. This will also probably necessitate that the spool be some distance from the tensioner. A similar situation may exist if the thickness of the tow, which is being laid down, is fairly thick. It should also be noted that if the filament is combed to an increased width, to eliminate the problem with thickness, it will increase the width problem. Smaller size tows may reduce this potential problem.

Hopefully, the taper is too small for this to be a problem. Reference golf club taper.

With a hoop winding, such as used on the torque tube, the back winding may absorb the slack in some filaments that was created during the forward wind.

Spreading (band width) will have an effect on strand length differential within a tow. This is because a wider band will mean that the strands are wrapping around the part at the same radius.

If there is the intent to use this machine to produce a filament wound rotorhub then the clearance about the A-axis must have a clearance of 12" radius.

Consider winding the rotorhub on an additional 'table' attached to end of the current table. The A-axis would be extended outboard of the existing one and the B-axii could possibly be used as a linear axis to serve as a supplemental X-axis on this 'side table'.

This CNC tool could serve for very light core cutting, such as the core inside the torque tube. However, the Clean room / Dirty room aspect will have to be considered.
