  • Franken-SB

    Great work Aaron - I have a similar obsession having recently becoming camping crazed. I took a slightly different path though!
    Ive always been a fan of the sunbeams - I like the thermoblock heating approach. so I decided that I would work that angle to get a totally gas/hand powered espresso. And like you, I was obsessed with also being steam milk efficiently. I started with this - a sunbeam EM4800 - $50 on ebay. Then i hacked - see next post

    Re: Franken-SB

    Hi all - heres the sequence of the builds. First I stripped out the thermablock and mounted it. For a pump, I scored a $30 caravan tap/handpump from BCF (or is that BFC). The thermoblock is mounted on the old front plate which is mounted on the original heavy base to give stability.

    At this stage I was toying with putting gas burners on it.

      Next - ditched the burners idea due to lack of power. Switched to a nice little blow torch head that a mate loaned me. lots of power! Heats to give approx 74C output in about 2 minutes. Lots of heat testing at this stage - thermoblock is reasonably quick to heat and slow to cool which makes controlling the heat via the torch really easy.

      Wanted more stability and everything included so took another part of the original machine to make the back section holding the pump - note the poor carpentry around the pump!

        Finally to today. Major issues were the pump - really hard to move when against the coffee (particularly on the upswing) and the wood bit were pretty poor and prone to cracking under the pressure of the pumping. (they also burn really well if you miss direct the torch!)

        Would love to get rid of the "crema" basket on the sunbeam group handle but will have to wait to track down a replacement basket (I think there was another brand that fitted but was a standard basket)

        Steam only happening periodically at this point - not enough of it to practically steam milk. (just a burble) - so have cranked up the heat and found one that sits nicely beside the unit to keep the heat on. So this is the final (as of tonight) version

          What is wrong with one of the other stove tops ?

          1: Reasonable cheep
          2: Small and compact
          3: Make good coffee and 2 or 3 shots at a time
          4: Plenty of Steam and a gauge
          5: Scramble eggs
          6: Light and pack away easily

          Or be trendy and go an Atomic ?

          Then again... What is wrong with being inventive..

            Re: Franken-SB

            Well after a lot of thinking time and poor workmanship, I made a great coffee on my machine tonight and then topped it off by pulling a shot and steaming up the milk for a fw for my wife.

            Easy to use and it works! The lever makes pumping much easier and the burner works well (but will probably add a second one to increase the heat for larger volumes of milk).

            Ive stuck a video up on youtube at http://www.youtube.com/watch?v=tJ-UuIoGMas

            NEXT - a really efficient hand burr grinder - perhaps burrs attached to a bike pedal/cog assembly mmmmmmm

                Thanks vicroamer! Re the why Angermangament - basically the stovetops were ok for camping just for me but as the resident roaster, I am oft asked to knock out 10+ coffees at a time around the camp site. So I wanted something I could use a group handle on, could have the h2o replenished on the fly (without another heat up) and would steam as long as I pumped - hence I went into hack mode.

                Also - it was a lot more fun to have the concept and follow it through - and most importantly someone told me it wouldnt work! hehehe ;D

                    Re: Franken-SB

                    The only improvement i would suggest after watching the vid is to carry a separate camp table with specific mounts on it so that you can stabalise the whole unit. Perhaps use screws with wingnuts coming up from under a table top?

                    Great idea though.

                      Like the idea of the screw in table - thanks - and Ill definitely be shaving my knuckles before the next video shoot!

                        What a great concept, it may be easier to use a stovetop but wheres the fun in that. I like it

                          Good stuff, I like to see people stripping off the stainless and getting down to the mechanics of brewing. Yes there are ready mades out there but you learn so much by getting your hands dirty and doing it yourself.

                          My project is currently still on the drawing board, but I am getting close to machining the first few parts soon, specifically building the bottom section of the boiler.

                            Brilliant Jaxxx,
                            I love the ingenious machine.  The video is great too, especially the soundtrack.
