Welding

 

Welding the Hull Plate

Finally, after making myself get out of the submarine building projects, it was time to start building a sailboat.

 

 

 

 

 

 

 

 

 

 

 



 


Flipping the Hull Side - Wrong and Right Way

 

 

We will have to flip each hull side over 6 times, welding a little more on each side every time in order to balance the weld contraction and limit the amount of distortion.

Yes, we can life a 5 ton piece of steel 18 feet into the air with two 3 ton manual chain hoist; but it's a lot of work and it took me 4 hours to complete.  ...so we broke down and purchased two 3 ton electric winches.

 

 

 

 

 

 


 

WRONG
RIGHT

We love our electric winches.  They are the best! Up and over in less than 20 minutes.  But boy howdy, they don't give these puppies away.
