Broad Ambition - The Model

[grendel]

i'm not sure why the engine kept stuttering, or why at the end i couldnt change the sound off the gunfire one, once i got it home it of course behaved impeccably, maybe it was just a loose connection

[Ray]

She looks great, I liked the onboard camera view 👍

[grendel]

well a bit more work, after the trial runs there were a couple of drops of water in the bottom of the boat, now not sure where this came from but i suspect a pinhole in the epoxy sheath over the timber, this will more than likely get sealed when i paint the hull, but just in case i have epoxied the area inside too. after that it was time to add the strips across the roof, and then the handrails, unfortunately one mounting point happened to end up where the support underneath was, but right on the edge, so a couple of blocks have been added to allow the threaded portion to sit through a timber with space behind for the nut.

[grendel]

this mornings task is making the handrails, i have some 4mm dowel, but its a little too short, so far this morning i have sanded a shallow splice onto the ends of the dowels, and one is gluing up in a set of v blocks.

[grendel]

well handrails made, and test fitted, also thousands of BA nuts and bolts sorted into sizes

[Ray]

The handrails look fantastic, really nice job! It's this kind of detail that really makes her become the real BA to scale 👍

 

[grendel]

there is a good half hours work turning each of those handrail supports and tapping them to m4

[Ray]

I can well believe it! To look so 'right' is testament to the work that goes into it!

well little bits as and when, the second well deck side went in this evening, followed by the bending of the water feed pipe for the exhaust, i've left the end long as i have to turn up a transom fitting, this will need to be threaded about 5mm or bigger to allow the 3mm brass pipe through, i had to heat the brass to cherry red before i could bend it satisfactorily , this pipe will need to sit under the servo linkage and will exit through the transom, after that an inner well deck will be templated up and fitted above the rudder post.

[grendel]

ok so its been a busy day, what with tidying my workshop to be able to find some things, then making the skin fitting for the exhaust outlet, first some bar had a centre punched, then centre drilled, then it was drilled out to 3mm for the tube. after that a section was turned down to 5mm and a thread turned onto it, after this it was parted off (though in hindsight i should have cleaned the thread with an m5 die first), then cleaned up and tested on a piece of 3mm brass tube. its now ready to install (hoping i made the threaded section long enough now) 

[BroadAmbition]

Down right showing off is what that is !

Well done and keep it up

ok, 5mm hole positioned drilled and the pipe fitted, tightening the nut was fun, but achieved, the other end has been sealed into the hull fitting, i will gradually open up the hole in the hull fitting until i get the desired flow. its less than 1mm at the moment

[grendel]

I have left the outlet pipe a little long, it can be cut down if needed, i might try swageing the pipe at the outlet for a good seal, though its a pretty tight fit anyway.

[grendel]

tonight was creating a pattern for the floor, basically i placed a sheet of thin ply as a template, using a spacer the outline of the internal space was traced onto the template, the template was then laid onto the plywood that would become the floor, the spacer was then used to recreate the shape from the marks made on the template, this was then cut out and fitted, its still a bit tight,but it fits in there fine, it will be trimmed to be a good fit later as i build up the well internal fittings and features.

[grendel]

another little job, swaging out the pipe in the outlet, then filing flush and polishing

[Polly]

Neat work!

[KaptinKev]

I have to say the work involved looks very intricate and you are doing a fine job with the small detail. I just hope that after all the hard effort that you have put into her, she doesn't hit an iceberg on her maiden voyage.

[grendel]

time to detail the rear well floor, sides cut out and the rear sections glued in place, next to line in the floor covering with the pyrography tool.

[grendel]

pyrography completed, i will add the remaining sides prior to staining the decking.

[grendel]

sides going on

[grendel]

i am using steel square blocks (used for supporting things perfectly square) to support the parts as i glue them.

[grendel]

steps being installed, they need to be linked to the floor, or the floor wont be able to be removed

[Polly]

Goodness me! This is going to look the real deal.

[grendel]

I will also point out that the majority of the non plywood timber has been cut from the two pieces of burmese teak that Griff supplied to me, which has been cut into planks of various thickness, and has been used extensively in the build of this model.

[grendel]

so this just needs the stain doing now. and cleaning all the paper from the glue joints, so that it didnt stick to the workbench, I put a sheet of paper down, as this can be cleaned off the wood.
