thoughts re materials.

Heres a quick blurb from the web in regards to HDPE and Acetal (which is similar to Delrin)

Key Benefits of HDPE Sheet and HMWPE Sheet:

Very low co-efficient of friction
Very high surface release properties
High chemical resistance
Excellent impact resistance
Very good damping properties
Weldable plastic
Excellent abrasion resistance

Acetal is the product oggy knobs are made from, pretty strong stuff.

Applications of Acetal Machined Parts:
Precision gears
Bearings with close tolerances
Electrical engineering insulators
Compact bearing assembly
Snap fit assemblies
Parts which operate in water between 60 to 90;C

I'd think they could both have great uses with nav towers. Great to see people using it.
If ignorance is bliss, why arenīt more people happy?????
