Re: Lines of a Hull

Aalexanov, glad you found the article clear and thanks for the post of the lines of the classic run-a-bout. Since my goal was to try to make clear the three classic views of the lines or hull intersections in the classic views; I used the dory shape in order to have the simplest boat possible for th...

Re: fred murphy

jenny, wondering about the design element of the knuckle around the fan tail? There's a clear and very distinct line separation from the rub rail or external channel (?) not sure of section used to wrap the hull at this break? And the sheet's forming the fan tail knuckle- which is a couple inches (n...

Re: So, You want to buy a welding machine...?

North, sorry for the poor reading comprehension!! You did address the AC TIG issue I just didn't see it! I've not used any power supplies with all functions in one chassis- regardless of brand- so I don't know what will or won't be present or how well that newer model will perform. I do like being a...

Re: So, You want to buy a welding machine...?

North, I'm not familiar with any "green machines" so I can't answer. I do have a dedicated MIG power supply (Red) and a dedicated TIG power supply (Blue) and haven't any experience except these two brands (and Hobart, years ago, now owned as part of Blue/Miller). However, any MIG system can be combi...

Re: So, You want to buy a welding machine...?

Miller MIG Power supplies. I want to take a post to mention recent experience with a Miller MIG power supply and to make remarks about the difference (fundamentally) between the Miller and Lincoln 350 MP systems. I've remarked before, not in too much detail, about some differences but now, having us...

Re: 25' Skiff Build

North, i see all the additional and previously unmentioned points!! I agree that if someone is married and that relationship won't stand the extra-work hours of a boat build? then it would be a good idea to find ways to shorten the hours needed to build. Marriages are way more important (in most cas...

Re: 25' Skiff Build

Hi Kevin - I agree with all of your points... with lots of hood time now.. for an amateur... I would certainly agree that i would have less distortion if I were to do it again.. Now have more skill and patience that when i started. North, very unfortunately for the good of many first time boats.......

Re: 25' Skiff Build

North, didn't you build the Glen-L Double Eagle, inboard ? Is that hull being offered as cut files? Not sure I'm clear on your remark about using an NC cut hull if you had it to do again? Perhaps I don't recall which hull design you built? Standards: Both Yofish and I try to build "clean hulls". Not...

Re: So, You want to buy a welding machine...?

Another aspect of aluminum welding that should be 'bumped' up here is welding 5000 or 6000 series aluminum with 4043 or even 4943 alloy filler. the welds will 'stick' but when they are bent backwards/break bend tested.... 4043 shows itself to be very very weak overall. However, many welders prefer t...

Re: So, You want to buy a welding machine...?

I regularly use expensive "professional grade" welding systems for both MIG and TIG. So I don't see much of the lower amperage systems' products unless I discuss them with others who own or have access to those types of systems. This post is about some "facts of life" having to do with a small "spoo...

Re: Metal Marine Tanks (mainly welded aluminum)

After some conversation about tanks' construction I thought I'd mention some links to some of the parts available online? I typically use aluminum pipe couplers, cut in half on the band saw as my tank wall weld in fittings. But... they're not for everyone! In the following links there are flange typ...

Re: 25' Skiff Build

Forum readers who're reading Yofish's build thread might be interested in some detail notes about this thread and welded skiff metal boats in general. First and foremost is this skiff wasn't built off full gunwale-to-gunwale transverse frames OR with a set of station molds inverted on which to form ...

Re: 25' Skiff Build

Yofish, I know the skipper was a giant, and stand up helms are a mutual design headache when you're accommodating the owner's height, I'm current working with a 6-5" or 6-6" owner but at least he's building his own boat! Given the 'well deck' in the house- domino effect to the bottom being hogged du...

Re: 25' Skiff Build

Yofish, thanks for the added images as explanation of the tank install. The 'off-to-the-side' views answer the questions about install itself but one design question remains; why the sloped 'beds' for the tank? You could have put a horizontal piece in place of the knee or sloped piece of bent materi...
