Let the Speculation Begin

Cap merely went by what Adams' article intimated linked below...

"The CNC router we've chosen for this project, by the way, has a 3 HP router capable of producing complex 3D shapes from blocks of plastic, wood or aluminum. CNC routers are the opposite of 3D printers: they remove material from blocks of wood or plastic, leaving behind the precise shape that you want. "

Unknot your shorts everyone.



Wood is too easily distorted by water, plastic and alum have undesirable properties that leech into water...some forum trolls have some pretty funny motivations.

Cap, wrong is wrong.  First you interpreted the affirmative statement by Adams of materials that he works with as an all inclusive statement of what any CNC gear can work on.  Amending your statement to say that Adams' equipment can't work on materials other than he mentioned is not supported by any fact.  Adams may choose not to work with harder metals for the simple reason that it takes longer to machine and wears bits faster.

As to materials for holding and transporting water, you are again wrong.  Hardwoods can and have been used for centuries for water passages and containers.  Wood resists bacterial growth.  Certain plastics leach unhealthy chemicals into water, others do not.  PET is safe by itself, but is not a hard plastic.  The problems with water bottles have been with hard plastics.  You can check with the Natural Resources Defense Council.  Aluminum in contact with water forms a layer of AlO3 that stops further interaction with the water.  Aluminum can leach when the water is either too salty or too acidic.  It would not be a first choice for acidic substances such as fruit juice.  But for water with a pH of 7-9, leach rates are negligible. 

And finally no matter what your opinion or someone else's may be of the suitability of a particular material for conveying or holding water, it is only Adams opinion that would influence what he might and might not use.

You take leave to call others trolls, but the statements not based on fact are coming from you.

|Again to clear up the intentional confusion...wood warps plastic leeches toxins(unless hemp based) and alum  is unhealthy.

The CNC issue is a belabored moot point of distraction.

To get back on the real topic...any guesses as to what Adams is up to ?

Here is a excerpt from that site...

"The polymer implants exhibited a mild tissue reaction..."

This type of "plastic" is likely the same as that used in hernia reinforcement...which turned toxic and had to be removed from those who survived the toxic shock manifestations.

This will be my last off topic response to master baiters here.

Moving forward.

Could you be any more disingenuous?  Let's see the complete quote that you chose to truncate:

The polymer implants exhibited a mild tissue reaction with the same characteristics as the control. Local tumor formation, bone osteolysis, and surrounding muscle necrosis were not seen. No pathological changes compatible with systemic toxicity by Delrin 150 were observed in the study of the organs. Delrin 150 in solid form did not exhibit local or systemic toxicity and is therefore biocompatible by this study. Powder implantation studies should be performed to simulate tissue response to wear particles.

The control was 316 stainless steel.
