While the paddle tug is at the fitting out stage I decided to start a puffer ,rather than do planking on frames I can get lots of scrap blue polystyrene from my work I thought about putting it between the frames and shaping it ,I read somewhere on the forum about covering it in card and then using easy coat to seal it ,I am making a jig at work to joogle the card and make rivet like dents to make the plates overlap and look as if their riveted, does this make sense or am I on a wild goose chase. Cheers Marky👍
Sounds brilliant, am looking at making a butty barge by a similar method but using polystyrene packing boxes, for towing with my tugs. Hope all goes well with your build, looking forward to posts. Cheers Colin.
Interesting article in Model Boats web site which mentions joggling, however I'm still none the wiser. http://www.modelboats.co.uk/forums/postings.asp?th=119534 and in addition an interesting article on decking in the Titanic Research and Modeling Association web site. http://titanic-model.com/db/db-02/bruce-1-db-02.html after some more research I found this comment by Ian Gardner "I find, when joggling planks into the waterway or king plank, it is useful, if you have the facilities, to grind a chisel the width of the joggling to chop out the recess in the waterway. This is usually one third the width of the plank being used if memory serves. The chisel can be made from a an old needle file and hardened after grinding." and pictures of joggled joints It appears its cutting into the waterway or king plank. In a way you can see the reason its called joggling as it gives the same profile as in metal joggling eg "Z"
in the bad old days when i had to put on the overalls and graft for a bob or two we used a lock former to joogle light sheet metal some times we used to get repair work in the yard and had to fold a joogle in 1/4"plate by putting a piece of flats bar on the leading edge and using the 50ton folder to press a joogle into the plate a.will do a sketch and post it when I can find a pencil which have all mysteriously gone walk about a.Cheers Marky👍
The other alternative method on heavy plate was heat and hit with a sledge hammer, as used when I had to repair a barge at canal side. using flat bar under leading edge and steel slab on topside. Hard work but so satisfying to see the finished job floating without leaks.
