So today was THE day!

Decided to go New Brighton with my pops to give her a water test (moment of truth as they say!) ..Turned out great, Still needs more ballast as I expected, But the 12-volt is plenty so no need for me to mess about with 24-volts :)

Anyway here's a quick vid!

Very good, the point on the bottom of the transom should just break the water, nemesis

cheers guys :)


Quite a relief when I didn't see any water in the hull! lol


Remember this is my 1st ever build so I was a little shaky! But now I can continue on with build, going to finish the electric box, then I will fix the deck & then i've got some Easy 1 Filler which i will seal the deck with.


Heres quick pic from today's test (only pic I got!) apart from the vid

It  is certainly interesting that after all of the trials & tribulations  %) for 24volt control systems, that a 12 volt supply now appears adequate

During the dry test, the motor presented an interesting resonance from startup.....equating to the sound of a constant speed fluid coupling drive approaching final speed

The dry test disappointingly did not display any clear motor speed control especially at lower shaft speed

So whilst higher shaft speed may be required for towing/manoeuvring work, a little more ballast aft may also be required to minimise initial cavitation

Hi Derek :)


To be honest on the dry test in the video I didn't really do low throttle much as when low RPM it was quite noisy & it was late night & I live in a flat so my neighbours wouldn't have been too happy!


But on this water test at low rpm she plodded along nicely & was very quiet/smooth, in this vid it was mostly 1/2 to full throttle (again very quiet & smooth) as i wanted to test the power on 12-volt would be enough (which it definately is) ..yup she is going to need around a further 10kg in terms of ballast which I expected :)

It is surprising just how much ballast these tugs take to get down on the waterline, also they were not that fast in real life, about 7/9 knots, enough for harbour work, so your test went well.nemesis

hiya,


yup needs a fair amount of ballast! I had a rough idea from the start of this project that i would need around 50kg ballast, seems i wasn't far off!

Couple of updates!
Ive been buzy with other stuff but now im back onto the build so heres a couple of things ive done:
Decided to make my own Mist Unit, For those that don't know baout these kind of devices, they are NOT the oil type smoke generator's, these ones run purely of cold water, nothing more!
I will be running it using timgarrod's board that allows more or less flume of mist depending on throttle, it also has a remote on/off switch that can be toggled via the transmitter, ive gave it a test & it works great, highly recommended, just fire timgarrod a PM if you want to know about these boards, on to some pics:

I decided to use 3mm clear perspex for the unit, to join the pieces I used a liquid called Model X Pro that is specifically designed for bonding plastic/perspex together.




The actual Mist device runs from 24v supply, so to hook it up im using a 24v step up as my battery is 12v. The fan im using runs from 12v.


For the outlet I used some plastic plumbing pipe, i fixed a small connector thats usually used for joining 2 pieces of pipe together, this was ideal as I can insert/remove the pipe for ease of transport

Hi guys!

Just an update as I haven't been on here in a while due to being busy with real life stuff!

Anyway I've updated my website for my build & will continue to post here with updates. As you have probably noticed most the images I posted in this topic are no longer working, this is because I have changed the domain of my website & I can't update the links in my posts on here as there is no option for me to edit my posts after a period of time, so unfortunately I can't fix the links here!

Anyway the new website for my build has all the info including photos,video's & detailed information regarding different parts of my build. I will be continuing the build next month so will update my website regularly! & I'm hoping to have the build complete before next summer comes around! I will also continue posting on here updates for my build :)

Just a heads up.. My website might look like a forum at first glance, but I have heavily modified it so all functions such as login/register are removed & the layout is changed , this is because I just want it for information only to visitors as I don't have time to moderate & keep tabs on who is posting what etc! I was going to just make a normal website from scratch but doing it this way makes it simple for myself to add/remove sections & media on-the-fly with ease :)

My new build website is: RC TUGS http://www.rctugs.co.uk


Cheers All :D

I've decided to build the Stack from scratch, the TID moulding came with a fibreglass stack but its out of shape quite a lot, i could probably sort it with alot filling/sanding but i thought sod it, build one from scratch.
So im going to use some walnut planking that i have to make it :) ...should be interesting, will post pics when i begin which will prob be a few weeks as im soon moving home! ^^

Why not use a piece of drainpipe the same diameter as the original.....just a thought and cut the funnel step that is on the deformed one

hiya dave :)
Great minds think alike.. kind of! :D
I did try to find some plastic pipe, but the diameter i needed was 90mm with around 400mm length or larger so i could just cut it, i looked at plumbing/sewage pipes but no luck & tried to search google for pvc pipe with those dimensions. so in the end i decided to just build one, i've done some research etc & i've made a start (few pics below). Good thing is it will give me some experience for when i scratch build my next model :)
A couple of discs done & fit onto PVC tube (not glued as yet just testing the fit), still need to do a few more discs then add some strip wood for the frame ready for planking:

Would be great if you could, problem is i have no idea what photos went in each post etc as they're named differently :(

but here is all my photos which i could send you via email to save you having to download them all, but like i say..i think it will be a heck of a job as you won't be able to know which photos went with each post :( ?

There is plastic pipe  near the size you want here but is quite pricey

That is expensive, i know some model materials are expensive but that place must be smoking some funny stuff with the price of them tubes!

think i will stick to making my own using planking, but thanks anyway for finding them...just shame about price ;)

Thats not silly smoking stuf expensive.  Youre in the architectural model realm and it looks OK prices TBH.  You can pay allot more!  -Professional models cost allot, much much more if every round or square tube is fabricated?  Also, UK is CHEAP for modelling materials.  EU is crazy expensive for same things

Did you try heating and re-setting your moulding?  Only time I rejected a set of mouldings that were so twisted and mis-cast useless was Metcalf -they were so bad I returned and got my money back.

Nah ive never done any moulding myself mainly because i don't have the space for a setup :( but each to there own i guess, im building my own stack from scratch now using planking strips etc, which is still much cheaper than that plastic tube which was actually 35 posted!
Ive bought quite a lot of items for modelling from EU over the years as it was cheaper than UK, all depends what it is your buying, there is a place in germany I shopped at often that was good prices & also shipping was faster/cheaper than some places i've bought from in UK! :)

Starting to take shape now, just need to cut the tube to size & then glue it together & then begin the planking :)
To give a rough idea of size, the black PVC tube is 32mm diameter & the height of the stack at moment in pic is 310mm, I've yet to make the bottom section of stack which will be roughly another 60mm.. im still yet not sure if im going to make this collapsible like on the teal TID.  Issue being is i will be using a Mist unit & the tube will run through the stack, so if i make the stack collapsible then i will need to make the mist unit tube collapsible also, so will need to have a think!
