Planking hull

[John S]

Can someone suggest a size of wood strip tor a Strongbow style hull 4 feet long. well not actually Strongbow but maybe Longbow is a better name as I am stretching the hull by adding three extra middle formers.

Welcome to PD's John.....

So is/was the prototypical vessel wooden planked? or a steel hull?

If it was the former, you could consider scaling the original hull thickness

In many cases this dosn't work too well, so I'll stick my head here and suggest ~~ 8mm wide x 2.0mm thick

Secure with 1.25mm diameter bronze nails + Titebond III glue

I will not suggest any wooden specie, [depends on the Land of your build] but suggest a fine grained semi soft timber that bends a little [even with steam in tight locations]

Finish the internals with a Z-Poxy type coating

Lets hope you get 20 different suggestions just to confuse you

No idea as to what the original was built with as the plan came from a German source supposedly a typical English paddle tug. I suppose it would have been whatever the original was built with so as it was Strongbow could have been almost any hobby materials. of course it is not Stronbow any more since to fit my boiler and inverted oscillating engine  I need a longer hull and as my frames are limited by an A4 size sheet I have had to extend so here come Longbow class. so imagine an aged paddle tug still retaining the original oscillating engines now no longer needed having been replaced by one of those screwed up vessels but still has life left. Time to enter the world of pleasure as often they were in years gone by but a bit small for carrying many fare paying day trippers hence extending the hull length. Not sure if they could do that with a wooden planked hull but in my fantasy world almost anything is possible. So far boiler materials to hand (5 inch copper outer, two 1 inch furnace tubes and a few of the 28 flues sitting on the floor beside me. For the hull so far 250 feet of 18 mm x 4.5 mm strips ripped from 18 mm thick board and 24 frames from 4 mm ply laboriously cut by my home made CNC router that just accepts an A 4 sheet width. Lastly a half built oscillator 1 inch bore x 1 1/4 inch stroke with slide valves and Penn valve gear and that took weeks of reswe5arching to find enough detail to even think of making it. paddle wheel frames for 7 floats cut from 2 mm aluminium alloy previously used for testing aviation rivets but they need trimming to look nice.  Not my first paddle tug though as years ago I made one about 3 feet in length from cut up oil cans that solder easily but these days oil comes in plastic containers that do not solder quite as well as tin plate does. The story goes on for many more hours but I suspect there are very few members who would like to sit down and read a more complete saga. This is a relatively new pursuit as previously I have been making steam locos from O gauge up to 7 1/4, steam wagons from 2 1/4 inch scale up to an aborted 6 inch Foden but always steam and I have now been doing this since 1957 so had a little practice and experience of what will work or just leak steam.

PS I am now planning something to thin the sawn strips to a more bendy shape so that is why I an asking for suggestions that may or may not be followed depending on how I feel  after OI have made the surface/planer, unless of course someong gives me a proper one free.

Hello Eddy, continuing on my search for planking my hull and trawling through the galleries for inspiration I came across some pictures posted by yourself a few years ago, well actually on October 25 2009. The photos showed a clinker, lapstrake or even clencher built hull that seems to fit my thoughts so I was wondering if after 11 years you could possibly let me have any more information especially about the planking of the hull and possibly more photos (big wish) as I am about to embark upon a similar construction for my extended Strongbow style. Hoping you can follow the first line in my message without too much difficulty. I have downloaded as many of the photos that seem to provide some information but ignoring the one with the electric motor in as the proposed vessel will have a twin cylinder oscillator fitted with Penn valve gear. John.

Sorry John I don't remember whose model that is.... 11 years later and LOTS has happened since then!

See if this helps a little John....

Eddy,
Thank you so much for the link, all downloaded but need to find 40 sheets of paper. Just what will keep me occupied for a long time so ideal these days of restricted outings. This is the easiest set of instructions I have seen, others were more for if you were on a boat building course so got very technical but with luck and perseverance I should have something to float next year that hopefully will resemble an 1850s clinker built hull with oscillating engines.
Thanks again for your help.
John.
