Are you Mecha-Done?

One of the most exciting mounts to come out this last expansion (personally) is the Model-W. This wheel mount comes in two variants, new and rusty. The rusty edition is dropped from Rustfeather with a 0.5% drop rate. The Model-W is a shiny edition that comes from a fairly lengthy bunch of achievements. I have been working on this achievement on my Alliance Warlock for some time now and thought it was time to look up the remaining portions.

(Note: Comparing achievements with my alts, it appears the meta-achievements are BOA. My son has Making the Mount marked completed, yet hasn't completed the quest chain.)

You can find the achievement under:
Character > Achievements > Exploration > Battle For Azeroth

It has 10 meta-achievements included in it. I believe the very first achievement "Unnamed Branch" is from completing the main storyline which concludes with killing King Mechagon in the dungeon "Operation: Mechagon". (update: as soon as I completed the dungeon on Monday, this achievement is now marked completed).

Rest In Pistons involves killing rare mobs that spawn all over the island. These rares can be divided into about 4 different categories; 1 spawn on a timer. 2 spawn during an event or quest. 3 requires the player to 'do' something to spawn it (cast lure, use a quest drop). I have a few of each still remaining.

All of the rares via Wowhead comment (plus my notes):

I've done most of the obvious quests for this meta-achievement, found that those that I had remaining are mostly tied to the same visitor. The daily quest "Clues Abound" results in a different follow-up quest depending on the item that you find. (ref by Wowhead user Fyeina)

1. Old Parchment leads to the Quest A Historical Mess
2. Ancient Runestone leads to the Quest A Growing Mystery
1. IMPORTANT: While you do the Quest A Growing Mystery, don't just kill the Mutated Lashlings for your Quest, kill also the Toxic Lurker and you will receive (after a few kills) the Night Elf Ring. This gives you the Quest Strange Discovery for your Achievement. If you already turned in your Quest A Growing Mystery the Lurkers cant drop the Quest any more!
3. Hearthstone Card leads to the Quest Time for Heroics
1. After you rescued Adalin Halfheight he gives you the Quest Deck'Em
2. IMPORTANT: While you do the Quest Time for Heroics don't just rescue the 3 Guys, also kill the Congealed Oil in that area and you will receive after a few kills the Old Pirate Hat. This gives you the Quest Pirates? I Hate Those Guys for your Achievement. If you already turned in your Quest Time for Heroics the Oils cant drop the Quest any more! If you do this in a Group only 1 Member can loot this Hat and has to share it to the others!

* As long as you are on the follow-up quest from Clues Abound you can loot the ring from the lurker and the pirate hat from the oil. You don't need to be on their associated quest. I was on Time for Heroics and got the pirate hat and the ring

1. Aim High - Daily quest that can popup, kill rustwing mobs near where Rustfeather spawns. (I've only seen the corollary to save 8 gnomes).
2. Taking the Air Out - Daily that's a followup with "A Direct Approach". According to comments, it's only happened once since 8.2 dropped. 
3. Cogfrenzy's Construction Frenzy - I couldn't find any construction projects last time, but now I can fly and it should be a lot easier to complete!

4. note: It seems the more people who successfully repair a Dismantled OOX-35/MG the more they will run back to Oglethorpe Obnoticus until he has enough to upset Tinkmaster Overspark (you will hear Overspark complaining about chickens). Once that happens you can start /tar OOX-Fleetfoot/MG. Chances are there will be so many people repairing chickens left and right that doing a sweep for OOX-Fleetfoot/MG at random intervals will land you one
