ohhh the "wheel" needs spinning 90 degrees.
gunna be a little awkward on this mock but i ill work on it.
i spent some time after upping those pics replacing the pins for some wire hoops and fitting them, then the thread snapped and its the only peice i had. so will pop to local cost co and buy one of those 99p sowing things lol.
as soon as i find my printer paper im going to print that image of the tiller mechanism out over 2 pages so i can work on the scale and once this non scale mock is completed i will work on the scale prototype.
CWMB sells scale puleys and stuff. i think some of those will do for the prototype and real one so tuesday going to order some of those and extra timbers for making the real one.

okay this is definatly on hold till tusday. i need to buy materials for it and i have to work on my pc system. the interactive voice recognition software has gone up the spout and as i only really use th keyboard and mouse for playing games, everything else is done by voice lol. so have to fix that up

okay done some maths.
the tiller arm is 29ft long, so working with the images i've estimated the cross section to be at 25ft.
using a scale calculator for computer accuracy that puts the measurements at the folowing.
tiller arm 4.6 inches
tiller cross section 3.6 inches
tiller cross section curvature 0.5 inches
depth and width will be 8mm this is pretty large and isnt exactly accurate. however this does leave more than enough room to install the rudder into the end of the tiller arm. and as i dont know the victories rudder thickness i cant work out the correct thickness. but we do have the ability to sand and sand and sand.
placing my rule in the rib frames on the keel with an inch sticking out the rear it does look to be about right.
i've mocked up a bending plate which i can place a peice of soaked timber and adjust the locking pins to begin the curve. this will take a few days and a few adjustments by moving the pins to get into the right curve.
i've placed a peice of scrap wood into the plate which is to the correct length for the scale and the curvature looks good.
i will try and get information on her rudder to try and buy the most accurate sized timbers for the scale but until then assuming 8mm will be best. this thickenss if correct, also allows me to hollow out a section of it to install the rope tensioner.
which if these need to be thinner, the rope and tensioner will need to be running along the top or under side of the timbers so the tensioner can still be installed.
cornwall model boats sells scale pulleys and sheaves which are an acceptable size for this project.
the cutaway section will need to be done as to access the rope tensioner if ever needed, and also just to be able to say, "HA look what i did! bet you cant do it" to my younger cousin lol
order for the timbers, parts and some .25mm hemp cord will be placed on tuesday or wednesday and construction of the scaled prototype will begin the following weekend if not earlier depending on delivery times.
pictures will be posted for a visual update as well as a log entered for each image.

Hi, Been follwing this with interest as I cant personally see the point unless you intend to make it RC!! but heres my working example! rudder til moves and the ships wheel moves the opposite way, which in the good old days they did!!      My 11yr old son thought it was facinating!!!!!!!!!!

thats a nice simple working example, the one being installed into the victroy will be more detialed though, iron bands with bolts and everything

okay first on the docket today is thickness scale.
i took the plans of the tiller kindly provided and scaled the image on screen to the correct size. then measured the thickness of the timbers used and have come to the following conclusions.
the thickness of the timbers that need to be used are 4mm.
however!
the tiller arm i will make to 4mm, but the cross section im going to make to 3mm so that the cross section can pass through a cut out square in the end of the arm and be fixed using iron bands and bolts. in trueth these will be brass wire and brass rods.
the sheaves from cwmb are a little on the large side. however i will order some anyway and see if i can replicate them to scale. probbly wont be able to but oh well, will try.
secondly, i got more thread and my upgraded mock prototype prototype works again! i will post pics of that tomorow.
very much looking forward to starting this build.
as for the commend bout no point unless making it r/c, your kind of right, there isnt much point, but in my personal oppinion its just one of those nice little modifications that i can look back and think, wow i actually put planning and thought into that and it worked!
wether anyone else does the same is up to them but hope it acts as a little inspiration.
oh and the stress points added by making this, should be able to compensate for these by upgrading the hing points on the rudder with a slightly stronger metal rod. but this will of cours depend on what the rudder hinge parts are made from.
so we'll see

well i placed the order today for all the parts, including some strips to deck the victories decks and some .5mm thread for chaulking and some 1mm black thread for the steering rope. mostly because this needs installing on the tiller before we are given the length supplied by deag.
so waiting daily from tomorow at the door for postman. also because my sark first issue wil be arriving soon too lol.
so im very excited and cant wait to begin construction of the scaled prototype.
i'e glued some bits of wood together to form a rudder type peice that i have attatched to a block wich the TSP1 (to scale prototype 1) will be mounted on.
there is also a simulated deck so the ropes can be routed to a wheel.
the hope is the hinges, wheel and all other bits will work as they should do and i can forsee any problems to come.
anticipation is killing me lol. anyway pics will follow once i have something to report.

well i'v got the scaled version of the prototype completed. the curve of the tillers cross section is going to take some rethinking, the 3x3mm wouldnt bend and stay so im thinking i will try and make it up from several layers of thinner timber and get that to curve. here you can see the rope tensioner.  another view of the tensioner  the rest of it   and a video of it working http://s813.photobucket....amp;current=MOV00151.mp4

because im moving my cutaway section to show the tiller system i decided to plank that area of the deck. while the lengths arent to scale being only 4cm long each not to worried about that.    ignore the bit thats cut out. mistook this deck for the middle deck. this will be covered by the planking luckily
