Re: Custom Tennant Sonic Build-Assembly Drawing
I wasn't suggesting parts be clear anodized, as that changes the color of the material and is more expensive. Treatment with alodine is less expensive by far and doesn't change the appearance of the material, yet stops it from corroding and eliminating the problem you mentioned earlier here:
"Aluminum certainly would be better for machining and allot cheaper than stainless steel, Aluminum will tarnish over a period of time in the hard to clean areas, that tarnish is called aluminum oxide, due to galvanic corrosion, stainless steel will look the same as it did the day it was first manufactured.
I know the prop was made out of aluminum. Only the transmitter will be manufactured out of 440 stainless, the rest will be aluminum.
The real prop was not intended to last, it to has galvanic corrosion in some parts of the transmitter housing, thats the gray and some black marks on the inside of the transmitter housing, thats the part of the transmitter that is hardest to clean, that's were you get the aluminum oxide forming the most, the other parts can be cleaned easily."
