[tizdaz]

hi,

Thanks, its getting there! As for the pics I just used the "Insert Image" then just posted them (the icon above next to the youtube one) I had already re-sized all my photos so they were all pretty much the same dimensions.

The code looks like:

lol

believe it or not, transport wont be too difficult (i hope!!), most of the weight will be in the batteries themselves as these will double up as ballast which are removable for transport (35kg) the electrics board will also be made removable & as will the structure! ..so all that's left on the hull its self will be the deck/fittings/supports & the sound/steam module which will weigh less than 5kg in total, I have a 7 seater car which i used to pick the hull up & it fits in with a little room to spare!

What a monster! I didn't really grasp the size of it until I saw your hand next to the propeller.

aye shes a big un' alright! When i went to pick the hull up i was preying it would fit in my car, even though i had measurements etc, the 150 mile to the location all i was thinking about was "it best fit in my car!" lol

Time for an update, Finally finished the rudder..

First I cut out the rough shape of the rudder from a 2mm Brass sheet


I then filed & sanded to give the final shape


This was the (not so fun) part! ..Silver soldering the Rudder shaft to the rudder it's self. I did this using a Butane blow torch which I picked up off ebay, I used 2 house bricks for a base, I then lay another brass piece I had on top of the house bricks (to help with reflecting the heat) I then keyed the area to be soldered using some sand paper & put some flux on the contact sides & then lay the rudder & rudder shaft in position using 20pence pieces as shims as these were just the right thickness so the rudder was centre to the shaft, I also used a couple of die pieces to keep the shaft firmly along side the rudder. It took about 5mins for the flux to run which indicated the correct temperature to add the silver solder.


All sanded down, solid as a rock! ..tested the alignment & all good!





I then used some JB Marine Weld along the joint, this ensured that if there was any area missed with the soldering this would fill the join as well as add extra strength.


Once the JB weld set, I then sanded for a smooth finish


Next I cut out 3 strips of 1mm brass & wrapped it around the shaft & onto the rudder, these were fixed in place using JB Marine Weld & then I used 3 small pieces of wood along with clamps to hold in place while it set. This will again add extra strength to the rudder as well make it look more like a rudder!


All set & solid!


Time for more sanding..


Next I added some rivets (well, kind of!) I cut off the head of some button head bolts, filed them smooth & then using JB Marine Weld I placed them onto the strips & then filled the head with the weld.


Once all set I sanded down to a smooth finish


One more final sanding..Mission Complete!


Im pretty happy with the final outcome, once sprayed I think it will look pretty decent, not bad for my 1st attempt




Next will be to perma fix the skeg/propshaft etc in place & connect rudder to the servo

Very nice rudder.  A lot of work went into it.  Be very interested to see how responsive your tug is with that big rudder.

Thanks olscuzbut,

Yeh I've put some time into making it, but been worth it

Can't wait now for her first dip in the water which will hopefully be next weekend, I just need to perma fix the keel/shaft etc in place then ready to go!
