Good guess Greg, she's 28" OA and 7.25" beam so far the hull only weighs 495 grams so should take a sizable 12 volt Pb battery that should push her along at a slow scale speed and will be the major part of the ballast, I use slings to launch boats these days because bending down and launching by hand I'd probably end in the water myself

so now I'm pre fitting the decks while waiting for the running gear etc. and maybe get the bulwarks prepared.

Looking good Joe!

Question Joe..... i know this is only a mock up, but won't this setup give you unequal throws?

radiojoe · « **Reply #29 on:** November 03, 2020, 10:08:36 pm »

Hi Martin, as you can see by the other two photos with the servo horn at that angle with the servo centred it give equal throws well near enough, but not sure yet whether I'll use this method it was just an experiment

I've been pottering with the rudder today, and thought a brass one would be best, I've used a brass tube for the stock and cut a slot for the rudder blade to fit in and then soldered in place I think this will be stronger than just soldering a butt joint on to a solid stock, and then as the blade is only 0.5mm I thickened it by laminating some 0.5mm styrene each side, and the running gear arrived this afternoon so the shaft will be next to fit.

So yesterday I was just going to fit the shaft but got carried away and did the motor /ESC etc. and remembered just before bonding the shaft to fit a greaser, today I started bonding the decks down, I think I need to get a new radio system my old Saturn 6 is playing up a bit, it is twenty odd years old, when trying out the set up the motor kept stopping and starting like it was loosing the signal then I tried a cheap 2 channel wheel radio and it ran perfectly, the Saturn 6 is running four models so a new one with a few RX's is on the cards ho well Christmas is coming

Joe
loving your build of the puffer, this is one thats on my mind to build from an old magazine so it interesting to watch all your build methods, keep up the good work to the very end

Are you sure your radio issue isn't just a dodgy contact? On the old Planet T5s the battery contacts weren't terribly "springy" and over time they tended to lose their pressure on the batteries, leading to just the sort of intermittent operation you describe. Probably worth a quick check and a gentle bending of the contacts to place more force on the battery ends.

The puffer is coming along nicely. In the water by Christmas??

Thanks Trucker, yes interesting little boats hope you get around to building one

Great minds think alike Greg, I had checked all the batteries on the Saturn Tx. all seems to be ok and the indicator lights were steady, I have since tried the Tx on the Huntsman that uses the same system and it worked ok so I think it might be the Saturn Rx I used in the puffer that may be at fault the lights on the Rx and the ESC go out and on again, I also tried bonding the Rx again, but the ESC runs fine on an old wheel RC,. wifey's been asking what I want for Christmas so a nice up to date RC system will do nicely.
I must admit the Puffer is coming along better than I had thought after my initial concerns about cladding the hull, although the detailing will take time, Main deck on this morning and port side bulwarks this afternoon, even found a funnel for her (denture tablet tube) at 1:30 it's about 2 foot dia I'm guessing close enough.

Finished fitting the bulwarks, and I've been thinking on how to mount the rudder so thought I would pre fit it while it was still fresh in my mind, as you can see I've changed my mind about the concealed tiller arm I was inspired by George's (ooyah/2) chain set up so I hope he doesn't mind if I do something similar, it does look more authentic, next up is the access upstands, I've also been pondering a Scottish sounding name for the Puffer, I've come up with LOCH DOON

Then I discovered it is an actual Loch in Carrick, I may well go with that.

I prepared the mast by putting a reasonable taper on it and fitted it though the deck and notched it over the keel so the mast is self supporting and the shrouds will not need to be tensioned that much, not all things go to plan having previously done the battery stowage I realized with the mast in place I could not get the battery in, as usual the simplest solutions are best and I just notched the bottom of the mast to clear the battery, so the mast will still be able to be glued in place, also did the access upstands, next will be all the fiddley bulwark support webs, once these are done I think I'll get the whole hull primed with two coats of primer one grey to show up all the blemishes that I'm sure will be many, once these are dealt with I'll prime it with red oxide.

radiojoe · « **Reply #39 on:** November 13, 2020, 04:13:21 pm »

Bulwark supports and shroud plates done, next is the bulwark capping and I fit a couple of steps up to the aft deck before the first primmer coat.

Bit more done today, bulwark capping and various strakes, I must emphasize it is not any particular Puffer just my version from various photos so Puffer-ish, I wasn't happy with the Hawse holes at the bow I realized I'd made them too large so I'm busy now making collars for them out of styrene to close the holes to more scale like.

Joe.

Mark T · « **Reply #43 on:** November 14, 2020, 04:42:30 pm »

Thats a lovely job on the capping Joe..thats such a difficult job on any build. Love it mate and looking forward to the next update

dougal99 · « **Reply #44 on:** November 14, 2020, 04:57:38 pm »

Definitely has the air of a Puffer. Lie it a lot. Congratulations.

SailorGreg · « **Reply #45 on:** November 14, 2020, 05:14:40 pm »

Not sure why you aren't happy with the hawse holes Joe. They look fine to me. I somehow doubt you are going to be troubled by water entering through them, unless you are planning some very adventurous sailing!

Coming along very nicely. And it's great to do a freelance model when you can add as much or as little as you like. Nobody can say you've got it wrong because you are the designer and builder and by definition you are correct!

Greg

radiojoe · « **Reply #46 on:** November 15, 2020, 09:56:23 am »

Thanks for your comments and encouragement guys, the hawes holes were 10mm that I realised after cutting them equated to approx a foot in dia. seemed a bit too large to me, a small error but things like that bug me so a made some collars to go both sides of the holes and closes them to 6mm or 7 to 8 inches that is more pleasing to my eyes, you're right about freelancing it's great fun and having managed to get the hull done I am now settling into the best part of the build for me superstructure and detailing, I don't plan on having her in the water before the Spring and lets hope this horrible time will coming to an end, so I'm trying to take my time and enjoy building over the Winter months, so give me a lot of time to do more detailing, I was just going to paint the decks but now think I'll plank the aft deck and foc'sle so I ordered some Tanganyka 4mm x0.5mm but before that I'll still get the hull primed and mask off the aft deck and I'll do the foc'sle deck on 0,8mm ply sub deck, then the cargo hold cover and the engine room/wheelhouse, that should keep me busy for a while.

Joe.

radiojoe · « **Reply #47 on:** November 16, 2020, 04:38:51 pm »

I keep thinking of things that could be spray primed along with the hull today I thought the rudder servo mount could be done and then thought of the Tabernacle, I've attempted to make this look as though the mast could be lowered even though it goes through to the keel also fitted the Foc'sle sub deck that will be glued in place after planking.

Joe.

Joe ,
The Tabernacle looks fine here is a pic of the original one on the Skylight wreck.

George.

radiojoe · « **Reply #49 on:** November 16, 2020, 06:24:55 pm »

Thanks George, That's actually a lot more lightly built than I would have thought, I'm glad I used the thinner ply now.

Joe.
