Step 4: Dome

Now normally I would be providing you with tons-o-pictures of this step, but I misplaced my brand new shiny 16gb, class 10 SD card with a gazillion photos on it, the horror.  Suffice to say you will all have to deal with my sketchy descriptions.


Have your dome marked out, and cut it in half.  I just followed the weld lines from when it was originally put together.

Cut out a disk to fit in the bottom of the dome from your plate steel, creating your new tank.  The disc should slip inside the dome by about ¾ of an inch.  Don’t attach it yet.

Mark off where you want your hole for the water to be poured in and cut it out.  Really the size should allow quick easy pouring yet at the same time you don’t want it to huge.  From the other half of the dome cut out a suitable sized lid to cover the water entry hole by about ½ inch on all sides.  Fit the lid on top of the dome covering the hole and line up where the hinge should go – mark it.  Take apart the hinge and weld one section onto the door and one onto the dome.

Get your round plate you cut for the bottom of the tank and place it over the bolt hole for the BUNN tank.  Mark its location and drill a hole just ever so wide enough to allow the brass locking bolt to fit through.  This will lock the dome and the tank together in the end, so take your time.  The tank should be below the disc centered with the hole off centered by a couple inches.

Flip the dome over and insert the dome bottom “the one you just drilled”, it should fit into the dome by about ¾ of an inch.  Weld a continuous seam all the way around attempting to make it water proof.  Will caulk it later just to be sure but try your best anyway.

Next cut a 1 ½ inch strip of thin steel the diameter of the dome inside bottom.  Attach as you see fit, for some reason I riveted it in, I could have welded it though, oh well...

Going back to the scrap dome, drill out a hole the size you want the large black center lens to be.  Then cut out the triangle shape around it.  Drill 2 holes through the triangle shape and plug weld it to the top dome where you think it looks best.  For the actual black lens, you are going to use a trick I learned on one of the astro-droid websites.  See the finishing section at the end for directions.  Remember were looking for the best interpretation of R2D2 as a coffee maker, not a museum quality copy.  Assemble your various lens holders and weld or glue them on.  Mine were made of brass and aluminum which you can’t weld, and just epoxy seemed sketchy.  My solution was to hold the hollow tubes against the dome where I wanted them to be.  Then using my welder put tack welds on the inside where the brass meets the stainless steel.  Though this doesn’t weld it together, it does weld the tack to the dome.  The molten metal melts out a small section of the brass or aluminum and the steel pours in.  This locks it tight to the dome.  It also provides a lot of irregular surfaces for the epoxy to mechanically join to.  Which is what I did next, put in a heaping dollop of quick set epoxy.  The pokier lens needed something special, so before filling it with epoxy I drilled a hole down the center right through the dome and out the bottom.  I then put some automotive LED’s in the bottom feeding the wires through to be hooked up later.  The I simply filled the entire lens with clear epoxy.  This sealed the bottom hole and locks the leds in place.  It also looks like a lens.  Later will hook it the wires.  In the event the led’s burn out, simply drill out the epoxy and LED’s all together and feed in new ones followed by fresh epoxy – easy!

Mark off the dome and tape it off.  Razor trim out the sections you want painted and peel the tape off.  Paint 3 light coats of anodize-it blue paint and allow to set.  Quickly and gently remove the tape.  Touch up where ever paint was peeled off with the tape.  Anodize-it paint looks great but is a little weak being a lacquer.  Paint over with clear enamel hard coat.

Make sure to study the pictures, I’ll try to add more that hopefully explain it better, really need to find that SD card, damn gremlins.

I believe the correct term is... <br> <br><strong>NERDGASM!</strong>
This is probably the coolest thing I have ever seen. I wish some place like <a href="http://www.canadascaffold.com/struck_steel.asp" rel="nofollow">steel fabricators vancouver</a> would just make these and I would buy them.
OMG! you could make this epic machine into a baby....holder? yeah and it'd be so cute...if you have kids of course
This is wonderful! Wish I could work metal (I know little about welding and so on) you should sell them....I'd so buy one!
Thank you, you have to think of welding as hot gluing at slightly higher temperatures, its almost as easy.
That is the most brilliant description I've ever heard of welding!
Hey well done on winning the metal contest! I was so excited when I saw you took the grand prize this is just so darn cool! And (and I'm so not techy) I think it I had the time and tools I could do this myself! Awesome instructable!
Congratulations, you deserves the prize!
I love your title for this Instructable :-D
Why thank you
Heya! That pic of the lady with the coffee machine reminded me of Faye from Questionable Content comic! She made a dinosaur coffee pooping machine. You could try that next :D <br> <br>Here's links to all 3 of her espresso machines: <br> <br>http://www.questionablecontent.net/view.php?comic=1644 <br>http://www.questionablecontent.net/view.php?comic=1882 <br>http://questionablecontent.net/view.php?comic=2173 <br> <br>- Antzy
Ha, my wife loved it
hehehehe... whats 'it'? your cofee maker, the comic strip or the coffee maker in the comic strip???
All 3 actually, that and the heroine
Glad you guys liked it... :D
this robot is called &quot;android&quot; i think :P
The word was coined from the Greek root &aacute;&frac14;€&Icirc;&frac12;&Icirc;&acute;&Iuml; (anthro/andro)- 'man' and the suffix -oid 'having the form or likeness of'. <br> <br>Not trying to be harsh, just thought i'd clear up that deficit in your technical vocabulary. I have not met many men that resemble R2D2 in even an abstract way, so i figure R2D2 should not really be classed as an android. <br> <br>kthxbai.
whole world did the same mistake about this fellow :) and R2D2 must be his parent keeping in mind their similarity... Because of their design it is difficult to decide what are these things but i think you do agree that they are (r2d2 mind is dead so -&gt; was) too smart to be just simple robots. and i think that is the reason of calling them &quot;droids&quot; :) because of the smartness but not the shape :D <br>BUT I MEANT THE SHAPE AT THE BEGINNING :D
very valid points. i stand corrected.
In the movies, R2D2 was referred to as a &quot;droid,&quot; presumably short for android. Correcting mjagutis is pointless; you should correct George Lucas.
&quot;Help me, Juan Valdez! You're my only hope!&quot; Cool idea for Star Wars geeks.
Awesome! My lovely wife barely tolerates my coffee stuff, this might cause violence in my house. Then again I do have like half the counter covered with coffee stuff. I suppose if I made one look like a character from Grease she wouldn't mind, but that ain't gonna happen.
nice, which character though
None sounds about right. I hear Grease, I go fishing. Or wash the car or cut the grass or hit my head with a hammer until it stops. I sat through that when we were dating. Sort of how she used to cook until she got the gold. Just can't handle it anymore. I imagine Travolta would be her favorite. Or possibly he's the only actor I can name from the movie. <br> <br>Seriously, it's one thing to say hey that's cool and another altogether to be able to visualize it before you build it. Your coffeebot really is cool. <br> <br> I'm not very creative, most of my junk around here is born of necessity. Or from my being cheap. That's why I have a gutted and modded popcorn maker to roast coffee in on the counter, I'm too cheap to buy a roaster.
That's hilarious. never did quite work out the bugs to roast indoors. Did the same thing and filled the lower half of my house with coffee bean chaff...
Stainless perf from mcmaster-carr. Make cylinder that fits in the popper top and weld or solder on a cap. Chaff tends to fall back in when done but helps keep it off the floors. I suppose if you made a mushroom shaped top like a fresh-roast that would be even better.<br><br>I am trying to slap together a drum roaster right now from an old bread machine. Fun Fun.
This is AWESOME. I love it. Would you sell it??
yes, though being made of heavy steel, shipping might be an issue for weight
How much!
huh, haven't thought that one through yet to be honest.
First, Great work on the R2-D2 <br>Second, I'm really sorry to hear that SOME People cant read the red box bellow when commenting. I mean come on, if you spend your free time dissing other peoples work that they spent LOTS of time and effort on then try REALLY hard to find a new hobby. <br> <br>&lt;3
OH, not here on instructables. Generally everyone on this sight is awesome, sometimes criticism, but always constructive which i love. This instructable is going slightly viral and its on other sites where its been picked up that the comments were made. Thank you though!
AWESOME. If I had any technical skills whatsoever, I would try and make it. As I don't, and would be more likely to kill myself or severe several fingers, I'll simply droll jeaously over yours. <br> <br>Oh, and us tea drinkers will be watching Star Trek: Next Generation, thank you very much, drinking cup after cup of &quot;tea, earl grey, hot&quot;, along with our Captain (who is waaaaay better than Kirk. And begin &quot;which is the better captain&quot; match now) :-P :-D
I like to tease my wife and son, both tea drinkers...
Not only an excellent idea executed well, but beautifully and meticulously documented. 5 Stars and gets my vote.
whoo-hoo thanks! Its in the metal and food science contest as well!
Love the instructabe!!! <br> <br>Coffee holder should have been 3PO's head. <br>When the coffee started brewing he should have exclaimed &quot;Oh My! I think I smell coffee!&quot; <br> <br>Has anyone told your wife her smile looks like Gabrielle Carteris' from 90210.
Nice! that would have been funny! and I'm sure she would be pleased
Gorgeous!.........Coffee Maker ain bad either.....lol
wife went - TeeHee :)
Now that is one fabulous project!! I'm sorry you had to deal with awful comments earlier. Your family looks lovely and R2D2 looks happier in a family environment, not being shot down by Stormtroopers!! <br> <br>The Bunn concept is very cool - I always enjoy making up the coffee whenever I'm helping at my husband's office (I don't work there but help him when he does the Red Cross blood drives.). We just recently got us a K-cup type deal when our old coffee maker died...but now... I think this would be so much cooler!! Maybe I need to figure out a way to steampunk my k-cup coffeemaker...
Thanks, were more or less over it, more of the &quot;hey, that's not very nice&quot; shock of it. The bunn maker was a little tricky, think it might even be easier with the K-kup kind
Now my husband would probably go more for a TARDIS type coffeemaker... or the Captain Picard &quot;Tea, Earl Grey&quot; model... ;-)
That would be awesome!!!!!, my daughter collects all things Doctor Who, she wants her door painted like a tardis!
Just one word: <br> <br>WOW!!!!!!!!!
thanks, it turned out well
I never thought inside coffee makers were such material for steampunk projects! <br>It's beautiful!
I know, lots of good stuff in a BUNN. However a regular drip coffee maker is quite boring
