"Spike" sneak peek... (first machined body)

[Jaime Vallés]

Dear RED Team,

Stop with all the good news. You're going to make everything else in my life look bad.

Quote of the day, man!

 

[Eugene]

We are looking at Invar for much of the lens mount. Great properties for expansion (lack thereof) with heat. It is heavy so we are working out how to use it with minimal quantity and maximum efficiency.

If you need outside help with specialty metals, Carpenter Tech might be the company to got to for advice and materials.
Carpenter Technology Corp. (CRS)

"Carpenter Technology Corporation engages in the manufacture, fabrication, and distribution of specialty metals and engineered products. It offers specialty metals, including stainless steels, titanium products, high temperature alloys, electronic alloys, tool steels, and other alloys"
They do ceramics too.

The finish will be textured powder coat. Unless we change our mind.
Jim

Textured, but hopefully not rough - the better to clean it!

Jim said : The production body has been changed to aluminum... but again, more changes are possible.


Question to me : My " R " is not a same material to match my RED one ?

At least to me that It 's a logical to use the key and the lock with the same material made.

Any reason not using the Material made of " T " as used in the US Space shuttle ?

Aluminum is a good heat conductor

Jim mentioned a while back that heat was an issue they were working on (as in, circuits generating too much of it). I don't know if it played a role in the decision or not, but one possibly relevant factor is that Aluminum has about 10x the heat conductivity of Titanium.

See for example, http://www.engineersedge.com/properties_of_metals.htm

I doubt the Space Shuttle uses titanium in any place where they want high thermal conductivity. Ti is good for strength-to-weight ratio, but Al has lower density and far better thermal conductivity. If your camera shuts down after a few minutes due to overheating, you'd probably be unhappy with it, even if you can still use it to pound nails...

and about 10x cheaper..

 

[Dave Valiket]

and 1/2 the weight

 

[Brook Willard]

and about 10x cheaper..

Yeah, but this is the film industry. More expensive means better.

 

[Finner]

Yeah, but this is the film industry. More expensive means better.

In that case I guess by the time you have saved up for a red you will be happy that it is 3 times the price.

 

[jbeale]

Yeah, but this is the film industry. More expensive means better.

You better believe it! Look what $85,000,000 can buy:
