Broad Ambition - The Model

[grendel]

a bit brassy

[grendel]

I thought i ought to make up the bracket that holds the horns, so i bent a piece of brass up, and filed out for the necks of the air horns, these were then positioned and fluxed up, heated with a blow lamp and soldered in place, seen here on the forward cabin roof.

Beautiful!

Aren’t they just

beautiful they may be, but i realised i had made a mistake, it was when Charlie posted an inage of his pennant, with the port and starboard horns in the picture, i realised my error - my horns were too short. as you know, when i am not happy, i go back and do it again, so now here is the first of the new longer pair, i had made some purchases, done some changes, the old unimat motor was replaced with a 120W 24V scooter motor, this can run off my 0-30V power supply, and although slower the motor has way more torque (i cant stall it, and it runs way cooler, so motor fitted, and time to do some work, some new collets had arrived so it was time to thin one end of my 1/4" brass to fit a 4.8mm collet. the brass was then mounted into the collet and using my reading glasses and illuminated magnifier, the internal shape was turned, then it was making out where everything needed to be and get down to work removing lots of brass to form the longer trumpet part, this achieved and smoothed out with finer grades of sandpaper, and we had the first air horn and a big pile of brass dust from turning. bear in mind this  is about 24mm long and 6 diameter max

There is no end to your patience, precision and attention to detail, it looks perfect!

[grendel]

[BroadAmbition]

got to build the mounts next.

What?

You mean you haven't done them yet?

[Maxwellian]

[BroadAmbition]

Then you Have to build the air pump.

Erm, considering the original full size versions are 12v DC

However, stop winding him up,       otherwise he probably will

Ian, just you wait until the model sneaks up on you when you are out on the river then gives you a blast on its horns (note to self, make sure QE2 foghorn sound effect s loaded on sound card).

Additional sound effects could include a 'raspberry' and maybe a suitable sound to reflect her 'fart-boat' heritage.

Or the sound of Griff's wallet opening?

Think you will find it very difficult to obtain a recording!

[grendel]

I will just use a clip from the munsters where the front door opens then.

[BroadAmbition]

Oy you lot!

I will have you know two things,

1)  I have feelings 

2)  I strongly resemble some of those remarks

Calm down hullaballoos! Loving the progress and the attention to detail, have you thought about taking up dinghy ragging? Not shore what scail this is, about an inch to a foot.

[grendel]

well finally i have finished off the horns, all nicely polished and mounted, just the wooden mount to go under it now

[Ray]

Beautiful! 👍

[grendel]

you can see the cotton bud i mounted in a modelling drill to achieve the polishing, add some chrome polish and you get a miniature parts polishing mop.

[grendel]

not having anything better to do and needing to stay within a quick run of the WC, i decided to do a small part for the model so out with a short length of 1/2" brass and into the lathe. first all my tools needed sharpening, so once this was done it was time to forget my woes and do something. a couple of hours work later and the ships bell was done

[Ray]

Beautifully done! I wondered if you may have an update today.... under the circumstances!

[Polly]

Exquisite

Beautiful … but why did it make me think of Chuck Berry?
