IW, I guess I don't understand how a watertight bulkhead works. If a chamber is watertight and doesn't have a vent, how can it be pumped out? If it can't be pumped out, how do you remove condensation, how do you know if its leaking? How do you test it? How do you keep hot air from expanding the cham...

[quote="warthog5"][quote]So I have been thinking of running a seperate 1/2" fuel line with a plug on its end down to the transom so that it could be fished by hand out the main drain holes to fill bottles with a screen, and be used in my truck on the way home, or disposed of. [/quote]...

If they are only 10 x 2 x 28 inches thick like lester says then that opens up a lot of areas to weld on a fitted lock box in the bow on an alloy boat and it may fit in my motor well on the Cape.

I have to import the plate and other buyouts into Mexico. We do have the capaity to cut locally with plasma up to 8x22 feet in our shop if need be.

But I hope to cut them with a router in the states to pre kerf the edges and eliminate the heat distrotion on narrow pieces if possible.

I allready have the 24' design with the 8'6" beam in a CC or forward Sport Cabin, but a couple of friends want a walk around cabin.

So we are looking at getting a 30 x 9'11" alloy cat speced out for CNC cut plans.

[quote="welder"]Bull, not to take sides here but Dave was just worried about Bashing of a brand of boat weather it be Pacific/Blacklab or Cape Horn . Between the 3 of us we own all 3 of them . We just don't want to start a bash here , Carry on.[/quote] I am not bashing, and tried to make t...

There are about 4 rules you have to follow when placing them on the tramsom. 1. Go as deep as possible as bubble sucked in at the bow will move away from the deeper water pressure. Placing transducers is shallow water out near the outer chines seldom proves successfull except on very slow boats. 2. ...

[quote="welder"]I just went to , lrse.com and they come in all kinds of sizes 20"X28"X10" 70+lbs. then +- either side of these dimentions. For a 4/6 man raft with a lot of goodies with it, Flares , water, food and other extras. I also read that in time off need [ on THT, by ...

[quote="JETTYWOLF"]BS'er... I've been paying close attention to your posts. Do not come here and start some personal debate. And the disguised post aren't working. This isn't THT.....we haven't had any problems yet, and we won't.[/quote] Dave, Do not take this the wrong way. I don't carry ...

[quote="Nat"]there have been alot of cases around here where boats have sunk because the bilge filled with water and the pumps were not working, some while tied up at the dock, some while offshore I took a tour of the Cape Horn factory and saw the process. That was the day I knew I would n...

Underdeck Foams I like the idea of an unsinkable boat, but do not think that shooting foam underdecks will really keep the boat upright or save it and its passengers in a fire or cold water. It is also fairly expensive, retains water/gas unless it is reopend to create drain passages. It also prevent...

I have some general questions, that might make individual threads on there own, but I would like to star lumping some together. Underdeck Ventilation Is it not more desirable for air to enter the underdeck area near the bow to ventilate the underdeck area to remove accumulated fuel fumes, evaporate ...

They are advertising one on bloodydecks used for hooping that looks small simple and clean. Don't know anymore details.

I am looking for a how to manual, applied to aluminum boats in general. I know what general systems are required, but am looking for the code that specs the materials for the main electrical systems, and backups. Since the coast gaurd is buying aluminum boats, I would think that they might have some...

What type of isolation materias and be used to isolate SS rod holders and SS fasteners from aluminum hulls? Is the negative post on the battery the main gound for the entire DC circuitry on an aluminum boat? How do you isolate the hull against AC wiring circuits? What is the ground, the hull? Are po...

Is there a formula to determine how much surface area of zinc in needed for so many square feet of aluminum hull and where they should be placed?

Can you back up your systems if one set of zincs fail?

Can I assume that air should be blown into hatches, and that the hatches should stay uncovered prior to and during all wiring and welding jobs? What happens if a wire sparks under decks while underway? Couldn't riser pipes with vents be placed at either ends to force air under decks while under way ...

Its my understanding that the push pull is almost essential with the soft al wire, so it sounds like the more expensive set up is the way to go.

I will check my other MIG machines to see if they are tig capable.

Thanks for your guidance on this.

That weld looks pretty good to me. I see a lot of variations in price on these units running from $4-$6K new which I imagine depends on the guns and wire feeders. Any suggestions as to which feeder is best for a shop that will use it a lot, and if the pulsed machine really runs cool enough to use th...

Ed Wing in Washinton used to make a 21 and there are also kit boats from the southern cross. These are the best I've seen.

We have 5 300 amp Miller migs at the shop, but no spool gun.

I was wondering if the newer square wave mig machines were worth the investment and if the python gun was the way to go.

Is there a lofting program that idiots can understand, something that will interface line drawings from generic cadd or autocadd that you have tried that is suitable for the technically challanged?

Just wondered if you have ever experimented with the auto fill ballast systems to help eliminate roll on deeper dead rise hulls that is popular on the Bar Crusher and Fisher Al monos being produced in Australia?

Hey Lester,

This is a good idea. Thanks for the invite.
