MMM Portgarth
« on: January 10, 2015, 12:35:07 AM »

Hi all,


 Ok so I have started my build of Mobile Marines Portgarth (pictures to follow soon), and I am just looking into bow thruster options.mimwonder, what dia. Tube would you all recommend? I have a motor and prop shaft already.


 I'm also going to be asking some advice on lights, as I have very basic electrical knowledge I'm a little concerned over the installation of the nav lights, towing lights, bulkhead lights etc.


 So far I've done the various cut outs and have started the installation of running gear, and cut and prepared the parts for the Skeg.

If you choose to use Plumbing Pipe make sure that you rough up the outside of the pipe where it will be in contact with Hull, Glue,  Filler, Resin or any sealing compound as it doesn,t take too kindly to bonding...

Next question is on ESC's, I usually use electronize but I've been considering action electronics. Should I stick with the electronize?

Hi Adam


What size motors are you using? 12 volt? I think action will only take up to 12 volt but electronize will take up to 24 volt if you need a bit more beef for towing.


thanks

NO you are wrong about ACTion electronics they Do make them that will take 24v and more

Thanks you two, the motors are 12V, plus a separate motor for bow thruster and one for a working winch.


 I've never used ACTion electronics gear, as I say I've always used electronize. Should I stick to what I know?

Allways used ACTion used and abused it for years and it allways bounces back....had serious issues with Electronise in the past so will never use them....at least you have a dammed good back up the ACTion gear
 
 
Dave.........no connection with ACTion only a happy custoer

Thanks Dave, appreciate the reply. I know a few who have had trouble with electronize gear but I haven't (not yet anyway).



 For the tug, which I will be towing with, which ACTion units would you recommend me if I went down that route?

Adam
You say that you will be running the main motors on 12v but there's no mention of the voltage of the thruster and winch motors. Can you tell me what it is/they are?
Do you want to use a motor mixer or have independent throttles (tank steering)? Not sure - see "Do they both go round, mister" here http://www.action-electronics.co.uk/art.php
How many batteries will you use i.e. one big one or two smaller ones, the latter either in parallel or 2 @ half-voltage in series?
Are you planning on adding further working functions such as lights?
I ask because there will probably be a suitable wiring diagram already on the ACTion website here http://www.action-electronics.co.uk/wd.php although it might not be headed Portgarth. If not then one can easily be adapted - there's only so much you can fit into a tug.
Stavros is indeed a loyal customer and he seems to be getting more sensible now he's become a dad. I can't remember the last time I mended anything for him!

Thanks Dave...and Dave!


 My motors are 12V, BT is 7.2V and my winch motor..as yet undecided.


I have however, whilst beavering away this afternoon, got apair of electronize FR30HX speed controllers handy, brand new. So, I may just fit these for the time being. However I still wanting to go along the ACTion route at some point.


 I'm unsure of weather or not I'll want nor need tank steering for the tug. Unlikely I think, but not out of the question. I will however be adding working lights yes.


 Also, I have a few different type of batteries but I think 2 smaller batteries will be the case.


Today, I've finished the Skeg off, sealed, sanded and smoothed. Running gear is part way through fitting, which I will finish tomorrow.

Hi Adam,
I use complete action electronics running gear in all 20 of my model boats, esc's/mixers,power boards,fuse holders,amps,sound units etc...
Ive never had any issues with Action units all are top quality and back-up service is A1.
All the best with the build. :-))

Thanks Dave appreciate the advice re. ACTion gear, I'll absolutely be ordering some up for several boats, both built and and future builds.


 As far as this build goes, I've take some 20 photos so far and I will (honest  :embarrassed: ) get around to uploading some! I'm about to start with stringers and so forth for my decks, once I am happy with all that lot, I will make sure everything below decks is as I require before final setting of the decks.

I wouldnt bother with a bow thruster in a twin screw tug, more expense, more to go wrong.

Really should introduce some photos into this thread!


 Having a bit of bother with the curves on the front of the deck house, but perseverance will pay off I hope!
Got the hull primed and ready to accept colour now.

Ok folks, it's been a long time coming that I put some photos up of this little beasty.
 Now, be gentle, but comments and critics are all welcome as it's advice I'll gladly take on board for future builds!

The hull as it comes:


The work begins, with cut outs for the running gear and wash ports etc.


Fitting running gear:




Bow thruster fitted and sealed inside and out. Ready to be smoothed down:

Next up, I fitted and tested the running gear/motors etc (but no pics as they came out blurry for some reason!).
 Then on to the decks, gunwhales etc:




A coat (or several) of primer and the red oxide for the lower hull:




Each time, running down smooth with very fine grade wet & dry paper (but used dry).

I also started the superstructure:

I have now moved on somewhat, and have applied the blue (Svitzer colours) to the hull. I applied several coats over a period of time, and I am pretty pleased with how it has turned out so far.











 I did a lot of searching and viewing photos of the real tug, and the waterline appears to alter on occasion so I have gone with what I think looks right for the model, and I think it looks right.
