Making Graphite Arms

Just ordered a new Max v2 and also bought the all metal hot end upgrade. As long as this is a new build I would like to add carbon fiber arms to it so I don't have to fuss with it later. I found a YouTube video on making them but it does not disclose what ball joints were used or what adhesive was used to glue them into the graphite tubes. Can anyone help? Or should I just buy them from someone? If so, who?

Most people use the Traxas 5347 rod ends.
In terms of glue, you can use Epoxy, CA glue or gorilla glue at the very least, I like CA glue because I can use a single Jig and get a set within a day.
If you make them yourself, be aware that the length between the ends is a CRITICAL dimension, the length itself isn't really critical but if the rods are not all the same length, you cannot fix the issue in software or by calibration, and you should be aiming for better than < 0.1mm difference across all of them. As I mentioned above I used a single Jig to make the entire set, I've seen some people use a Jig for the set, if you do that be damn sure the Jig is square.
Or just buy a set from TrickLaser.

That said, the new stock arms with the ball/cup mechanism look really great, and might actually have better performance in terms of backlash than the traxxas rod ends. If I were you I'd try those out before opting for carbon fiber arms.

Graham, WA checking in!
You really (and I mean _really_) need to build the machine stock first. I say this because it's much easier to get the machine built and calibrated with the stock parts and you'll be in a better place to decide what you feel you'd like to upgrade if anything at all. (If you want to print high-temp exotics like Nylon, get an all-metal hot end from E3D (no clones!) and if you want to be a god of PLA printing, get a J-Head from hotends.com[*]
The arms do not need upgrading at all, unless of course you either a) like the look of carbon fiber arms or b) hate high-precision injection molded parts.

[*] These won't be available for much longer - the Chinese have flooded the market with J-Heads that are utter shit and have ruined the reputation of the design, thus basically destroying RPW's hot end business. It doesn't help that there's a whole LOT of whiny bitches out there that think $60 for a well-engineered, precision made, hand built, American made hot end is just too much for their precious little pocketbooks. </rant>
