Steel Boat restoration

[bert]

That's what I thought too so cutting it out is my only option.

It needs to be done right as it's been valued at quite a bit more than 50k.

 

[winchman]

Great project.
Not my thing but I do like it
I agree with the cutting out and welding overplaying is a bodge, fix it properly and add photos to the history file it will make a much better job and hopefully keep her afloat longer

So 6013 rods but what size? My machine can take 3.2's but not for very long.

Over plating is the nautical equivalent of oversills on a car then I'd not trust my welding abilities where the requirements are "not to let in water or sink"

Looking at Bert's mini restoration thread, I think we can all rest assured it won't be bodged!!!

from a guess the hulls original thickness will be 4-5mm then 3.2 will do.

 

[bert]

From drilling into it it feels like 5mm thick so I'll order some 3.2's

I might take down my tig as that has mma as well and use the tig if necessary to ensure it's 100% watertight.

Just remember that there will be at least five times as much to do as you expect

my favorite saying when people asked me to do an inch of weld. for every inch you see there is 6 to do

On a good day

I've just booked a survey for next week so ill know exactly what needs to be done then.

At the moment I've got 3 1" holes so ill happily take welding up 18"

The dutch do build nice steel boats ,, they only start to go down hill once they get wet , friend had a 36 ft dutch motor sailer , it cost over 20k to give it a '' nice '' coat of paint , and that was fifteen years ago , and a trip back to the factory for a few weeks too , the costs add up very quickly.

No expert, but if you cannot gain accesss to the rear of any weld areas how do you propose to make sure all the welds done from one side only are perfect?

The wet/dry shop vacs are quite good, we emptied a boats bilge of oily/watery mess the other day with one, I was impressed as had never used one before, so i am thinking you could mi=x up some soapy water and clean the bilges then vac the mess out?

I used to use one of the big white oil drainers to do the engine beds in my boat and it did very well. May not suit your job if theres flakes or the likes floating about , but great on low solids water / oil mixes , and cheap ish and needs no electric .

Yep take no risks there ..... Newspaper >P40 > underseal

P40 that’s posh, what’s wrong with pollyfilla, I mean it’s waterproof once you cover it in emulsion.

 

[bert]

I wish I could use p40, the epoxy filler needed on v
boats is ridiculously priced at £50+ for 500ml

Today I investigated the last locker in the hull and found more water this time only about 70l which must bring the total to nearly 500l or water I've removed from the hull. The deck must have been letting water in for years. I've stuck the biggest dehumidifier I've got down there and it's showing 99% humidity.

No chance the hull's pinholed?

 

[awemawson]

test if it's fresh or salt water - that'll give you a clue where it's coming from
