    Old propane tank

    I just finished the exercise of updating the entire propane system on my '83 H34. The original "system" consisted of a bottle tied to a U-bolt in the lazarette, a pigtail to a regulator with no gauge, and a line from there to the stove. Everything exposed was rusted and/or deteriorated. We never...

    H-34 Manual Fuel Check

    Thanks for that. The only complication is that there is no existing sensor; hence the project to install one. I was a little concerned about drilling a hole in a tank full of diesel, but after a bunch of reading I've concluded that it can be done perfectly safely.

    H-34 Manual Fuel Check

    Hi Claude, Do you remember what length sensor you bought?

    1983 H34 Main AC Circuit Breaker Replacement

    Thanks, guys. The original panel was made by Bass Products out of Marblehead, MA. The model number on it was 96-H34/36/37. Surprisingly, they're still in business and while they no longer carry the original Airpax one (I found the exact model number - IPA-66-1-30.0-01; very similar to what...

    1983 H34 Main AC Circuit Breaker Replacement

    I want to replace the main AC circuit breaker in my early vintage ('83) Hunter 34. The existing one occasionally breaks the circuit (Note: it doesn't trip, it simply stops transmitting power). I can usually toggle it back and forth a couple of times and it will come back. Once I had to unplug...

    H34 Compression Post One More Time

    I think the reasons we haven't heard of anyone who has used a floor jack are first, that it's steel, not stainless or aluminum, and will therefore be difficult to maintain if it tends to get wet, and sooner or later will have to be replaced. Second, anything that's adjustable will slip in the...

    H34 Compression Post One More Time

    I wrote up what I did in the hopes that it will help some others in the same way that the write-ups by several others helped me. I'll also send the drawing I made to anyone interested.

    Yanmar 3GMF Hard Starting - Air, Oil, or Fuel Pump?

    I was just looking over old threads and realized I never closed the loop on this one. The answer was the fuel pump. The original mechanical pump was shot. My Yanmar mechanic said it was far easier and more effective to add an electric fuel pump than to replace the existing mechanical one, so I...

    Bomar Hatch Gasket Material

    My '83 Hunter 34 has four Bomar hatches, and all the gasket material is in tough shape. I was going to replace it with the original thing, but the price stunned me. This is nothing more than 1/2"Ø rubber with an adhesive strip on it. Is there anything else out there that will do the job and not...

    H34 Compression Post One More Time

    Just to close the loop, air dried and kiln dried are essentially the same thing. In either case, it's considered to be 10% moisture (compared to 50% moisture for green wood). The only difference is time; air dried is literally that, left to its own devices to dry, versus kiln dried where you...

    H34 Compression Post One More Time

    Seeing there is some interest, I will certainly post some pictures when I get a chance. I'm in between work trips (home for one day) so I don't have time to do it now, but I'll try to get to it next weekend when I get home. I can also send anyone interested the actual fabrication drawing I made...

    H34 Compression Post One More Time

    Sorry, I've been travelling and didn't see this earlier. Thanks for your kind comments, and for inspiring me to double check the numbers. I originally just used an old reference I had, "Engineering Materials and Their Applications" by Flinn and Trojan. That says 3600 in the grain direction and...

    H34 Compression Post One More Time

    For anyone interested in this topic, I did the compression post repair on my H34 over the winter. I did nearly exactly the same thing dcalif did (2x2x0.25 aluminum square tube with a honking big header block at the top), with one major difference compared to what anyone else has done as far (as...

    1984 Hunter 34 issue with interior floor frame

    I was going to reply to Capt. Robbie's post, but Will already did. One clarification and another comment: ☼ The coefficient of thermal expansion is a number times 10^-6 (not 10.6), meaning 10 to the power of -6, and can be given as per °C or °F (or even K). The length units don't matter because...

    How to splice 4 Conductor 18AWG Cable?

    How important is the shielding? There will only be ~4" of unshielded wire.
