      Just happened to be in the right place at the right time today to procure a Mount Gay 30 RC yacht. I had offered to buy the very same yacht many months ago but my offer at the time was significantly less than the asking price and not acceptable.

      Today it just had to go.

      According to Uncle G there were approx 30 Mt Gay 30’s imported into Tas in the 80’s and those that have been viewing our Youtube videos from the early days of our sailing at the Canal will no doubt remember the red & white “Little Honda” Mt Gay 30 that was regularly sailed by our dearly departed sailing buddy Alan Furmage.

      I have not seen this particular one sail but it appears as if it’s not going to take too much work to get it back on the water.

      The rudder needs some repairs & re-centering, the rigging needs a bit of work to straighten the mast & get the sails setting correctly and the sailwinch arm will need altering as currently when the main is full 90 deg the jib is out almost 180 deg.

      Other than that she all looks pretty shipshape, even the 9X8C V2 receiver installed in the boat was a direct match for my Turnigy ER9X radio that I generally use for yachts. She could be back on the water as early as next weekend.

      A couple of pics

        Thanks Kermit, yes she looks good on the water.

      After a lot of head scratching & a couple of false starts I finally came up with a simple way to waterproof the open hatchway of the Mt Gay 30.

      I decided something was needed after getting water inside the hull on her first Puddleduck sailing & after reviewing the onboard video footage it was fairly obvious where it got in.

      As can be seen in the previous post the hatch cover was simply a piece of Perspex sitting on a timber lip.

      I have now 3D printed a solid surround that has been silicone sealed into the deck

       

      This has a raised internal lip (similar to a “Tupperware” seal) to which is fitted a 3D printed cover seal.

       

      The frame is printed in PLA+ and the lid in PLA Flex to allow it to stretch & seal.

       

      The new frame & cover do not interfere with fitting of the cabin top

       

      Next job will be tidying up the paintwork on the cabin top and hand rails etc then onto the sails & rigging.

      After a recent sailing @ Puddleduck chasing another Mt Gay & a few DF65’s the poor old Badger II was found to be carrying a significant amount of water ballast. With so much water inside her it was easy to spot the leak.

      It turned out that virtually the whole hull to deck join was badly leaking so all the previous work waterproofing the hatches was having little or no effect.

      At first it was thought that some self levelling epoxy poured into the inverted hull may have been enough to fix the problem but on closer camera inspection of the joint from inside the hull it was decided to remove the entire deck and start again.

      The timber Servo/radio/battery/keel mountings had already been removed as they were showing signs of water-logging over a long time & their removal allowed for easier internal access to the hull.

      Control Gear Timberwork & bulkhead removed

       

      Inverted deck (after removal)

       

      The hull (with deck removed)

       

      I guess glues weren’t as good 20 years ago or else “Badger II” was built more as a display model but whichever the reason there was very little persuasion required to get everything unstuck with the only damage being the rubbing board around the deck which came off in quite a few pieces.

      First order of the day will be fibreglass the alloy keel into the hull then 3D print & install mounting braces for the keel & rudder post. Once that is done then a new timber deck mounting rail will be installed & sealed followed by refitting the deck  after a bit of a clean up.

      Not sure yet but I may just fit a new deck entirely as it may be easier.

      To Be Continued…

      Seeing as I’m stuck inside on this cold, wet & windy day its a good time to get things done so moving right along with the repairs the new rudder support post has been designed, printed & fitted to the Badger II.

      she will be a force to be reckoned with when shes up running again  I bet that printer is worth its weight in gold by now ay

      • #3095
        PredatorPredator

        Yes Kermit, the 3D printer certainly makes modelling a whole lot easier & quicker.

    • #3098
      PredatorPredator

      The keel fin has now been fibre-glassed into the hull & reinforced with woven glass mat and the forward bulkhead (in fact the ONLY bulkhead) that sits under the mast has been reinstalled & epoxied into place.

      Keel fin & forward bulkhead

      Next job is to finish off the design of the new 3D printed Servo Tray and get that fitted so I can see where the keel fin bracing needs to be installed.

    • #3100
      PredatorPredator

      Keelbox & support bracing is next on the list for 3D printing.

      Design is complete & printing now underway.

      Keelbox & bracing to go over & secure the alloy keel fin to the hull

      Once this is epoxied in place the Servo tray can be completed & installed then I can think about refitting the deck and making sure it is sealed this time, which is where the job started

      Update:

      Keel box now installed.

    • #3102
      PredatorPredator

      Got the servo box designed & printed (10 hr print) yesterday so hopefully get the servos fitted & all reinstalled today.

      If I got the measurements correct there should be room for both the sail winch & Rudder servo, as well as a 5 cell AA NiMh battery pack.

      Thanks for the invite to the forum Pred. Trying to catch up with all the goings on over there in Tas. The forum seems to cover your local groups RC adventures well. As you are aware I am more theory than practical and don’t do much sailing here in WA. Hopefully that will change. Enjoying this upgrade of the Mount Gay 30, especially how new technologies fit in to the modelling process. Look forward to when its on the water, better keep it away from any fast travelling media boats on the canal. If we get back to Tas will put on the list a visit to the canal although after a recent video it seems a bit dangerous with that drone attack.

      • #3112
        PredatorPredator

        No worries Tug & welcome to the forum.

        I made a slight stuff up with the servo tray so am just in the process of printing another (hopefully correct this time) one.

        This time I remembered the step down for the rudder servo.

        I had Ron B (of Ron’s Reef fame) over this morning with his V2 Mt Gay 30 that he is also in the process of rebuilding. Have supplied some ideas & printed a couple of bits for him so hopefully we will have 3 on the water before not too much longer.

        Ah yes, Bad Angel & his drone attacks, too much spare time on his hands methinks.

      Thanks for the welcome Pred and Kermit. Will post a bit about myself when I get time. Know some of the names on here from Preds YT channel and ShipShape. Kermit I noticed that the other skippers did not come to your defence when under attack. More interested in their BBQ. Bit of a worry. More of a worry was just after I posted my wife told me their was a drone hovering overhead. I stayed inside.

      Tugboat cobber to set you strait on the “shoot up” we had moved from our flying field to lauderdale canal for our usual BBQ now there is a pecking order in our group an its an age thing  predator being the eldest  ( 81 )starts the BBQ bad angel is second  (79) so on an so on ….any one under 75 is a newbee   (that’s me at 71  )  I’m the only one…….  any transgressions by a newbee is quickly stomped on by the elders  my fault was I used bad angels sauce on my hamburger with out asking………. as in the pecking order  you don’t just go and sit with them you wait until invited   so whilst waiting I wandered onto the grass  and as you saw the rest is history  and you asked why no one came to my assistance , a lot of cars going past slowed down but I think they were intimidated by the rough necks at the BBQ to stop…… unless predator raises his finger no one moves to render assistance (such is the power of our leader )  Im not one to tell ferfies  trust me this is the truth ……. getting back to you   TUGBOAT  this name conjures up a vision of a portly fella  true? just curious   Nick names reflect a person   like” bad angel”   predator ..me ..UNCLE G so tugboat  that can be a start to your first post……   look through our site and enjoy our fun   Regards…. kermit la frog

      Continuing right along with the build,

      Servo Box in the midst of printing

      Note the two support bars for the stepped rudder servo section.

      Servo box & mounts installed, just sorting out the timber to re-attach the deck

      Once the deck is reinstalled the RC receiver will be relocated under the centre of the rear deck well out of the way of any water that may splash in.

       

      Close up of Servo Box & Mounts.

      The Servo Box mounts are 12mm x 6mm x 110mm 3Dprinted rails with 3mm Nyloc nuts moulded into the bottom. These are then epoxied into the hull.

      The 12mm x 12mm x 110mm aluminium angle is epoxied & screwed to the Servo box & then screwed to the mounting rails with 4 only 3mm x 10mm Stainless Steel Cap Screws.

      This makes for easy removal of the entire servo tray with everything intact by just removing the 4 mounting caps screws.

      Need to make up a timber strip cutter in the morning to rip the deck mount strips down to the correct size then the deck refit can start.

       

    • #3134
      PredatorPredator

      Got the Plank Strip cutter up and running today. Ended up with a Dremel timber cutting blade fitted to a Dremel Ez Lock quick release mandrel.

      Mounted it in a drill press rather than the Dremel and then just a matter of setting the plank thickness as the gap between the blade & drill plate and using a pine block to keep the timber pressed against the blade while cutting.

      4mm x 4mm strips are required to mount the deck as there is not much clearance between the hull & the safety rail posts. As long as its well epoxied & sealed all should work out OK.

      Starboard strip has been fitted & epoxied, now for the Port side & the stern

      Following this build with interest Pred, well done on your progress. How the use of the 3D printer as a modelling tool is of interest. It definitely produces a very  well professional product to exact dimensions. Mrs Pred missing a few pegs??? Kermit I will start another topic to answer your questions, leaving this topic for Pred to continue his build.

      • #3138
        PredatorPredator

        Yes, just a few pegs Tug, I ran out of spring clamps.

    • #3137
      PredatorPredator

      Port side deck strip now fitted & I’ve started to tidy up the deck ready for refitting.

      All the safety rails & posts have been removed along with the majority of the deck rigging fittings. A quick sand down & tidy up and the deck should be ready to go back on (and hopefully not leak!!).

    • #3207
      PredatorPredator

      About time for another update.

      All the deck mounting timber has now been replaced in the hull, the centre bulkhead has been built up so that it will now support the deck and the whole interior, including new timber-work and the underside of the deck has been epoxy coated.

      Next step is to refit the deck

    • #3406
      PredatorPredator

      My how time flies, it is almost 2 months since I refitted the deck to the Badger II and NOTHING has been done to it since.

      Been distracted for the last couple of weeks rebuilding a DF65 (ex Hoppy)but now that is finished, except for a set of A+ sails, it’s time to get back to the Badger.

      Today, after sanding the edges of the deck to better match the hull it was time to manufacture & install the rubbing strips to hide the deck/hull join.

      Cut some thin strips of timber with the previously built strip cutter then changed to a curved router cutter to round over the bottom edge of the strip.

                

       

       

       

       

       

       

       

       

       

       

      Started epoxying the first strip into place by attaching the bow end then once set epoxying the rest into place. I think once finished it should look pretty good.

               

      Time to get back to the gluing!!

      Nice build Pred, looking forward to seeing it on the water. Green Masking Tape??????????

      • #3432
        PredatorPredator

        Green Masking Tape, well actually its Painters Tape but it is a lot easier to remove than the standard variety.

        Got a bit more done today filling in the missing/damaged deck planks and have started to sand all the new work back into the correct shape & thickness. Will post some updated pics tomorrow.

      No, just a lot of things going on, between my wife and myself have been financing the doctors holidays and draining medicare. It will be school holidays for the next few weeks so that will keep us busy, probably no sailing as all the grandkids think it is to slow, not me it is very relaxing when I do get on the water. They prefer RC buggies, which is a lot of fun for them but keeps my pockets empty with all the repairs. But that is a cost I am quite prepared to cover as it gives us great times together. Have a few things to post and will see how I go over the next few days. You are a bit harsh on Pred, always been a gentlemen and willing to share knowledge from what I have experienced. But in the heat of battle we can all change I guess. Hopefully one holiday we will come your way and see for myself.

      Thanks for your kind offer Kermit, you never know we might come back again for another look at Tas. Do I have to dress in green as well? Have chatted to Pred over a number of years, cant imagine there is the side you are referring to.

        Don’t worry about the Frog, he’ll get over it. Just doesn’t like anyone stealing his coveted Tail End Charlie position, especially at the pond.

        Anyway weather permitting we will be back to flying next week (at a new field) and he can then take out his frustrations by throwing Kermit & Miss Piggy out of his multi copter at 1000 ft, more often than not with malfunctioning parachutes.

      Finally the end is coming into sight.

      Deck planking repairs & leak sealing is finally completed and the first coat of Spar Varnish has been applied. It will need a minimum of 3 coats with around 36hrs between coats so will take at least a week to finish off the deck varnish.

      Next job will be to strip the hull of paint and respray then all that’s left is to reassemble & tune.

      Gee, it may even make it back on the water before Christmas but as we start flying @ “The Field” (our new flying site) tomorrow the poor old Badger II could be on the back burner again for a while.

       

    • #3532
      PredatorPredator

      Three coats of Spar Varnish have now been applied to the deck and that is now finished and ready to prep & paint the hull.

      Thought I may as well repair the damage to the cabin hatch cover & re varnish the cabin walls before starting the painting.

      That way I can spray the hull & cabin roof at the same time so less paint waste & less cleaning up.

      Will need to apply 3 coats of varnish (recommended minimum coats) so once again that will take 3 or four days depending on the weather but at least the repairs are done & the first coat applied.

       

    • #3580
      PredatorPredator

      With all the varnishing now finished it is time to start the prep work for painting the hull & cabin tops.

      After much scraping & sanding all paint has been removed from the hull back to the gelcoat. This was required as most of the original paint was not well adhered to the hull, no undercoat had been used & I reckon there was still mould release wax on the glass hull which would account for the paint peeling & chipping so easily.

      Hopefully this time it will be better.

       

      Half way there !

       

      Well, that’s the hull stripped

      Now just need to sand the keel & bulb smooth then give the hull a once over with Wet & Dry to clean up any remaining marks then it should be ready for the primer .

      • #3592
        PredatorPredator

        Managed to get a couple of coats of primer on the hull today.

        If it all sands up ok in the morning I should be able to get the antique white top coat done tomorrow.

      Enjoying the build Pred, thanks for posting. Very quiet hobby wise over here. Just finished the school holidays over here and happy to report that all RC trucks survived and returned to the garage needing just some maintenance. As you would know from my previous posts on SS this is a very rare event and I normally have to take out a loan for the repairs. Hopefully some sailing in a few weeks. Is that picture of Kermit before or after he got run over??

      • #3600

        G’day Tug, yes definitely a rare event, judging from previous posts on the matter.

        I guess they are getting older & improving their driving skills, or perhaps they are just trying not to stress out poor old Granddad with the endless repairs.

        That pic is just Kermit in his BoBo the clown costume.

      It’s been some little while since any work was done on the “Badger”, in fact just checking back on the last post & it was October 20 when I undercoated the hull.

      Today, almost 7 months later, the antique white top coat finally got applied to the hull & cabin top. I chose Antique White as I think it better matches with the age of the vessel & the stained timber work than what Brilliant White (as used on the 10R “BattleAxe” and the IOM “Wedgie”) would. I just took the cabin top to the Spektrum Paints & they did a top class job matching the colour.

        

         

      I’ll give them a couple of days (or is that perhaps weeks/months) to harden & then after a quick tidy up around the deck trim, cut and polish and add the underwater black area (to match the original design)

      While waiting all the stanchions will need to be sanded & sprayed ready for refitting as soon as the hull is completed.

      I know to what you are alluding but just to set matters straight, actually it was I that caused the problem, yes it was Moose’s boat but I put it in there and then dropped it on my DF65 so the Moose was in no way responsible..

      It was such a lovely Autumn day today I figured it was time to finish the hull painting & then do the tidy up/polish etc when the weather turns nasty again.

      Three double header coats of Jet Black Acrylic Lacquer for the area below the waterline & the “Badger” is looking like her namesake again.

        

      Now onto all the handrails while the lacquer hardens up ready for buffing.
