    The vent pipe needed a little modifying and removing other parts.
    Fortunately, after cutting off, there was a flared end opposite the flange.
    Simply kept shortening the flare until by trial and trim, a stainless cap off a can of teak oil was a drive on fit.
    The lower half picture shows the cap well hammered in place.
    Probably not water tight.
    Only need sand tight, so it will keep the sand filling the tubes from leaking out.

    Then I bolted the two flanges together, and positioned the ammonia fridge where the old propane flue, now extended and sand filled, can contact the heat exchanger of the Peltier chip's hot side.

    This is as far as I got with the fridge today.

    I'll add another aluminum heat sink outside the tube, surrounding the flue tube, and meshing vanes with the box mounted sink's vanes, hopefully tomorrow.
    Between squalls.

    Then I'll test run.

    If the ammonia fridge cools from the waste heat of the lower TEC fridge, I'll consider my hybrid fridge a working success and install it in salon.

    But NOT exactly as configured in the picture! :D

    I think , tomorrow, I'll look for a copper or aluminum round bar to slip fit snugly into the steel flue pipe.
    Eliminate the sand and lower steel tube.

    Much improved heat transfer I'll wager.
    better chance of success.

    We certainly live in interesting times. and I don't need to convince you of the value of the internet to access new information.

    For about two years, I've been interested in super capacitors, multi farad, as battery substitutes.
    They charge MUCH faster, can be recharged MANY more cycles, and are quite smaller and lighter than batteries of comparable power.

    They WERE also quite expensive.

    Until I came across these instructions of making your own.

    DIY. My kinda stuff!

    Making High Performance Supercapacitor Materials - parts 1 & 2

    I'll be adding these projects into my boat construction.
    All that battery space under the bath tub?
    EEEEYHAW!

    Yobarnacle,

    You're either going to live in high style ... or blow you and your boat to bits! Jury's still out, but in either case, I've become convinced that it will be glorious! :)

    Well, I did mention in an earlier post, the improvements in 'GRAVY's' streamlining, makes her look ready to fly.

    But I hope she neither flies through the air nor flies apart.

    And I'm prepared to go to Glory, but not anxiously chomping the bit!
    I'll be content to wait another 50 years or so! :D

    Well, while you're waiting, I'll offer a likely much more satisfying form of "Glory".

    Didn't find any solid bars but found some aluminum conduit that will fit in the flue tube of ammonia fridge. Still looking.
    Don't want to too quickly settle for a burger when I might just as well have a steak with a bit of patience.

    Squally weather yesterday and this morning.
    Not convenient for resin glass work.
    Alright for cutting and shaping out of the weather.

    Redesigning tables.

    The rectangular tray table, (below) originally WAS intended to be permanently bolted in, with opening leaves for a top surface.
    Canceled the opening top with leaves.

    [​IMG]

    I've changed my mind.
    I'm using the tray as a easily removable multifunction table. It's light weight and can stow beside tub's port side when not wanted..

    It will appear the same as above when on top the dining table as sea rails for choppy weather dining.

    When on top the bathtub, it's an electronics work table capable of corralling small parts that could roll or slide around. Or similar projects.
    Can be used while sitting in the tub, too.

    It fit's snugly and securely as just a friction fit between inside edge of tub and the ship side. Only required a little trimming of flanges.

    Also, when tray is clamped on top the tub, it's conveniently beside my wife's EZ chair and can still hold her cosmetics and implements or use however she chooses.

    A few degree list in the tray, toward starboard, reduces likelihood items will roll out of reach, under the counter top along port side.
    Saves me from needing to notch tub's side. I actually prefer the small list in tray table.



    The smaller oval table will be rigidly bolted in place.
    Easier access to EZ chair, more room to pass between swivel Todd chair and end of table, more comfortable as side table for settee.

    [​IMG]

    Appearance wise, more in scale with cabin and furnishings, and more artsy/feminine looking for my wife. Looks a more appropriate match with it's pedestal size wise.
    Since my wife is left handed, the fattest closest part of the oval table on her left serves perfectly for her dining.

    [​IMG]

    And all this new functionality comes also with a beneficial reduction in weight.
    Those hatch cover leaves I've decided not to use on the table, were pretty hefty and stoutly made.

    Convenient as a galley work table, the tub mounted tray is beneath the SeaSwing stoves, and in conjunction with the portside counter top, creates an L shaped galley work area.
    Couple of ceramic floor tiles as removable hot pot trivets can sit inside the lipped tray.

    [​IMG]

    The dangling from overhead light fixtures are being converted from 12 volt incandescent to 12 LEDs in each with joule thief circuits.

    The support brackets I glassed to port side need to be adjusted by trimming so counter top is more level.


    A pair of cramped violent motion Vee berths, or THIS arrangement of quarters in the same space?

    Will you affix the table to the wall with pintles and gudgeons?

    When the tray is on top of the dining table, it will be secured to the starboard ship side with a horizontal fiberglass pin.
    Passing through matching holes in tray sides and rib flanges already part of the hull. That's sufficient to keep it on the dining table.
    On the tub, it's a good tension/friction fit, not likely to jump off unless really pounding into head seas, and I don't do that!.

    Thanks, by the way.
    Either twas you or your Mrs suggested using the tray as searails in rocky conditions.
    When I noticed the tray would fit on top the tub with very minor trimming of flanges, I was debating with myself, losing the tray as an under table possibles cache for my Mrs.
    Then I recalled the searails suggestion, and that clinched it for me.
    That amount of functional versatility out-weighed the single use as just a ladies secret stash compartment.

    Gracias, to the appropriate spouse/half of ya'll. :D

    I still need to make a tub top full sized chart desk.
    Something will inspire me.
    I did figure out part of the clothes washing apparatus.
    Roller ringers are expensive, about 100$ and up, and so are mop bucket masher type ringers, 60$ and up.
    I'm going to make a spinning perforated bucket powered by a cordless drill, as a fast centrifugal spin dryer.
    Two buckets actually, the outer one without holes, to prevent wobbling of inner and to catch the ejected water.
    So I don't spray all about like a wet dog shaking off water.
    Leaves the clothes damp but not sopping wet.
    Finish drying clipped to a halyard and hoisted into the sun and breezes.

    Or

    I might make a Tesla turbine to spin the bucket at 30,000 RPM, with compressed air.
    Be pretty dry I bet, after that amount of G's.
    Make the Tesla turbine out of CD disks.
    Not really serious on the turbine, but....maybe.

    Very cool (pardon the pun). I'd like to hear more about that.
