dalerod, the 70 page generic summary of MIG contains little new, or even some necessary test results (break bend coupons' tests) as references for the one-off builder in marine aluminum- so mostly generic info. The AC-pulse paper is totally new-material as almost Zero MIG [power supplies] offer this...

Yofish, I'll have to work on some images of the current build (might have to do a thread?) but I'm remarking about overhead welding- specifically. We rolled the last few skiffs I've built and this 34'er all on rotisseries because I've found overhead or above the shoulders is actually easier than bel...

Yofish, after seeing the gun(s) close up I agree that is a totally Miller product . The MK King Cobra is looks very similar but the details are the key to understanding: That is not an MK product. You have multiple guns to give your spares and back ups? So if one system hiccups you can use another t...

interesting Yofish... didn't know that Miller resold the King Cobra from MK?? http://www.mkprod.com/Supt_Manuals2.htm if you go down the page to the King Cobra manual there's little question of the origin of this gun system. I had the version with the water cooled / hollow gas cup and did one Bristo...

sky, the issue is not and never has been the exposure of aluminum to the atmosphere with its "healing" oxygen. If marine aluminum alloys can be exposed to free oxygen, not starved of it; they do fine. And all our discussions, read carefully, reflect this chemical fact of life. However, if aluminum i...

Yofish, is that a King Cobra by MK products? clearly push pull system just not exactly sure of what model? nearest I can find in MK's catalog now is the PrinceXL??http://www.mkprod.com/Prod_CobraSys_pxl.htm Had a King Cobra years ago, may still have it around?- had a water cooled/double walled gas c...

Glen-L readers, Yofish has shown a set of images that might cause those who haven't built in metal to ask how they are related? above we see a profile view of the sheer at the bow stem (gunwale forward tip) and the sheer is hogged; Yofish referred to that section as a "baleen whale bow" where I thin...

Longtail,
5356 will weld all 5052, 5086, 5083 and 6061 as well as 6063 although the latter alloy is not reliable in submersion for any length of time.

I use exclusively 5356 wire for MIG and TIG on all 5052, 6061 and 5086- we don't buy 5083 much here.

Cheers,

Keen observation of the last image Yofish posted will help my above explanation make visual sense. Notice in the light reflected on the inner topsides at the to vertical/butt seams in the topsides? ON the right/starboard side the sheet's meet with a uniform shadow/reflection/image of the light becau...

Many site readers aren't metal boat builders, and few if any have near the experience of Yofish. However, a point to clarify is the point about "sheet set" or sheet "lay" which can be roughly associated to wood planks- not necessary plywood but planks yes. As a plank, especially a wide plank can cup...

Glen-L Readers, notice that Yofish has removed mill scale where the welds will be located? Where the longs/buttock longitudinals and frames will touch or intersection the bottom panels- Yofish has buffed/wire wheeled/sanded or otherwise removed the mill scale so the welds can be put in onto "bare" a...

Will Jahrig is using this paint-on product to reduce sound, the boat in under construction - still- so the results on the water are not final.

Discussing buying a welding power supply and torch (of some kind) I received and email from a very thoughtful new welder who mentioned aspects of this thread, and others; which I have not really considered! I've been interested in and participated in welding since the 1970's and more or less assumed...

I think I've mentioned, several times fuel draw fittings and plumbing that is often used in marine tanks? This set of images is of a fitting that is available for installation in aluminum tanks to accomplish a few goals. #1 the fitting comes with a built in plastic riser that can be trimmed to lengt...

Sampot, I understand your work flow using D'ship for the surface modeling and moving out to Fusion/AutoCAD to do the various structural details. And like you and many other personal use- marine software users- I'm always moving from one environment to another to do the full work of a design. Low cos...
