Many thanks for your welding comments. With regard to the craters in the weld: They weren't so much craters as irregular indentations. The welds were on clean...
... This is kind of eerie :-) great minds must think (or at least daydream) alike... I "invented" a device like this (in my head and a couple of sketches) a ...
Question for all you steel boat people: what about mods to the hull/deck *after* the boat is completed? suppose you want to change the engine mounts or install...
Following this thread and relative to the welding power source in use, I am interested Ted, in the model of inverter unit you are using. These units may be...
Hi Terry Perhaps I could stick my oar in on this thread .... You raise some interesting points re: inverters vs. 'anchors'. My own little 140A inverter is a...
I'd just like to put my 2p's worth in the pot, regarding electrode choice. Although I remain relatively inexperienced, and would not yet refer to myself as...
Colin: While I would concur that 6013 is sufficient for welding sheet metal and is a good enough choice for low current applications, I would suggest that your...
was thinking one could be cobbled together out of ten speed bike gears, on one side the chain wrapped over the gear, on the other wrapped under, connect a set...
Hi De, I suspect that the cases of poor coating system performance adjacent to the modification or repair are related to the standard of the original ...
Jim, Here's a rough rendering of the mechanism I had mentioned. The green is the input from the pendulum. The blue sprockets contain the cam clutches that ...
For me the whole point of this endeavor is the fulfillment of an old, old dream. I want a sail boat. I want to sail to tropical places. I want to do this on a...

I am sorry for the intrusion. I will not lie. This is a one time visit to your group. The reason I am here is I could use some help. Any type of help you can...
If you intend to singlehand this boat off-shore, you should have one overriding priority: ease of handling - espeically under adverse conditions. If you put...
i am new to this group and have a quick question, for a pre employment test tomorrow i have a FCAW (flux cored arc welding) test, i have my CWB tiket...
I doubt hydrogen embrittlement would be an issue with the mild steel these boats are made from. With regard to strength, I have a book that lists FCAW wire up...
Jon: Interesting question. I was chatting with my father, today, about recent group discussions on suitable electrodes for welding 3/16th mild steel, as he - a...
This is an interesting topic. I've done MIG, TIG, Stick and Gas welding, but I've never even tried the flux cored wire. I have heard it is widely used in...
Yes production ship building uses Flux core arc welding and they use a shielding gas with it CO2 is the cheapest and most common. If there is a wind problem...
Hi All: I'm finding the discussion on welding very interesting and infomative. The high tech machines and wire etc. are all very nice and probably with the...
I'm not entirely sure your cost scenario is true. If you buy a used professional caliber welder, weld up your boat then sell it you may find that the actual...
Martin, et al: I couldn't agree more. As much as I prefer the speed & ease of wire feed (semi-automatic) welding, I chose SMAW when I had my shop in the...
To whomsoever is "in the know": What about the new "electronic" welding helmuts? In all my years of welding, I have never really perfected one essential...
Hi All: After a couple of years of working on Prairie Maid I've finally got the hang of the old helmet flip. It still drives me crazy when you go to weld and...
The electronic helmets are wonderful. I learned to weld with a standard helmet. My welding improved with the electronic helmet. It will change your reality...
Mike, I bought one 20 years ago when they first came out. Back then they were a little slow and you got a good bit of flash, but I learned to blink when I ...
Martin, visiting my daughter in Alberta, how far away from Red Deer are you? rt (My Island) ... and ... nice ... the ... purchasing ... good ... that...
Gary, I came accross an industrial quality AC/DC machine, paid a reasonable price for it, put a reohstat in and sold it after the last weld on the hull. It...
I've used one of those before and it was pretty good. Only problem I had was a bit of a headache once in a while. It was really handy in any place or situation...
