unbuiltnautilus,very nice build, been folowing for a while.
Love what your doing with moulding bits, I have some of that stuff, better get of my butt, and follow suit.
Thanks for the tips from your build

It floats and did well as a tug this weekend assisting a tug that had truly fowled props.

Spotted on a local canal this weekend.......more to follow...........

[bat44]

So how did go any problems with the boat

[Yarpie]

Good job.

Great to see this iconic vessel afloat.

More power to your elbow.

Sandy.

Cheers guys.
It floats. It didn't leak. Draws 5 Amps at full speed ( just made it up and back on one 10 amp battery ). Slightly light in the bows ( fix that this Sunday ). Turns in about a 10 foot circle, not bad for a 100" model. Bit slow, but that was mostly me taking pictures and enjoying the handling of the model, its probably a good regatta boat, I was playing in the lily pads with it!
Now I have to paint a Panzer IV for someone, and finish off Nautilus ( cos I'm selling it...tell no-one!), so Ohio work will now slow down again. At least it works though

[Yarpie]

In order to get the bows down to waterline (and below) just use the original cargo.

This is available not too far from Fawley Refinery by way of a pipeline, recently judiciously tapped.

But don't tell everybody ..... they'll give the game away.

i can confirm it performed very well on monday , it spent much of the day in the company of a coastal thames sailing barge and a springer tug

She really is starting to look the part. A very nice model.

 Scooby Doo back to Sunday moment ~  ~  ~  ~  ~  ~  ~  ~
 
 Before the maiden voyage at the canal, I spent sunday securing the various fittings to the model. this entailed scaling up by 1.4 all the dimensions on the plan. lots of pencil marks, followed by precision sticking with either epoxy or super Superglue.
 The fittings were pencilled round first. The decks then abraded with a hobby drill to provide a key. The bollards were drilled to fit and epoxied, while the home made tank vents were cyano'ed down without the use of an activator. Giving the glue more time to penetrate the timbers before hardening.
 Some of the vents are the correct spacing between each other, but have had to be shifted aft to avoid the metal pyro trays already fitted. so they look right but aint in the right spot!
 The 80mm Graupner 4 blade prop, bought for another job, was drilled through and tapped through, then an M5 bolt run through the deck from below and the two mated together.
 
 Scooby Doo back to last week~ ~  etc...
 The stern section has had its skylight windows squared up, I may have been drunk when drilling the holes originally, probably not though, just rushing the job. 32 Billing portholes later, thats complete.
 Support struts drilled through the boat deck had 2mm brass washers soldered flat against the underside of the boat deck. these were then superglued in place, giving me a nice flat area to bond, as well as the vertical holes.
 Some of my cast doors were fitted. I am having issues with this hot melt moulding material, having lost about five moulds so far, when the resin bonded to the hot melt rubber and would not let go. Not too major an issue as I can always re-melt the rubber material and start again, but a bit of a puzzle.

One of the teams recently refurbished/rebuilt tankers for scale, its only a 65" tiddler compared to Ohio

[unbuiltnautilus]

And finally those pesky stern section photos, as mentioned above.

[unbuiltnautilus]

Yesterday was re-ballasting time. We had an open day at the teams clubhouse, so members took the oportunity to fill the test tank and do whatever they needed to do. Me, add ballast to the bow and flush the ballast tank of sawdust!

[unbuiltnautilus]

Three years and one month since its last dunking in the test tank. Notice the deliberate mistake though? I forgot the diverter pipe for the 'drain' pipe. So the water shot straight up and back through the open hatches, into the boat again.... . Hence very sophisticated coffer dams being placed on deck.

It was interesting watching all the pyro trays float off as the tank filled. Need to address that!
It was also interesting seeing what had weathered the three years and one month better, me or the boat!

Boat looks fine.

 Klutz of the week award.
 
 I have been researching the proper colours for British Merchant Shipping during WWII. Found the following recomendations; Iron Grey for the sides, Dark Grey for the decks. i had both Humbrol 92 Iron Grey and Humbrol 67 Tank Grey. The Iron Grey needed a severe mixing to get both tins the same colour, plus a bit of thinning to get it to brush on easily. Job done.
 Went to pick up a couple of extra tins for back up..Humbrol 92 has been discontinued for about twelve years...no wonder it needed a bit of a stir!
 To the local specialist paint mixing shop then....
 Me and my hat and Ohio at Alfold on Sunday.

Coming along fine UBN.

The two watertight bulkhead joins are working a treat, no sign of hogging or sagging (as they say in the trade).

Will she be "active" this season"?

Worth a look.

[unbuiltnautilus]

 There was the slightest sag when we picked her up at the bow and stern. So do I tighten the nuts another quarter turn and risk loosening the bolts or allow a little bit of flex. We did launch with strops under the mid section though. Its proper heavy, so no sneaking down Canoe Lake at 8:30am of a Sunday to have a quiet sail, cos I cannot lift her on my own!
 I doubt if she will be fully display ready this season, lots of stuff to add inside and out and underwater, plus the usual display season commitments to swallow up all that spare time. So lets say years end to be fully 'bangy and sinky!'
 

[Yarpie]

I know of another large model, RODNEY, that sags alarmingly when lifted by two strops into the water. (By strops, I mean large timing belts and not the individuals)! HMS RENOWN's video quite clearly shows this. (I won't include the video link on this, your thread).

I feel you're quite right in not over-tightening the captive bolts to eliminate any movement. As long as the transverse bulkheads are strong enough and there's no water ingress, job jobbed!!

Keep up the good work and many thanks for the update.

Gandhi.

Sandy, the saggy bottom on Renown doesnt alter her performance on the water,or I didnt think so when you gave me the honour of handling her for a short while!
Alan, Ohio is coming on nicely,hope she will be performing next April,when we come up for our 25th Reunion.
Best wishes,
Mick F

Sounds like the best sort of incentive to finish the model

Hi Allen found this pic on another site thought it may interest you.

Sorry Allen wrong pic, try again

Hi,

Interesting read.

Attached is a photograph of Dad's WW2 Ship, HMS Prins Albert. and off the port bow the wreck of Ohio.

Regards

[unbuiltnautilus]

Nice image. Photos of Ohio are as rare as hens teeth. This one is new to me and will be scrutinized!

[Z750Jay]

Time for the big magnifying glass
