Broad Ambition - The Model

[grendel]

A bit more canopy progress

[grendel]

I am constructing  the actual canopy cover from a suitably coloured card, here is progress so far, next is the rear section.

[BroadAmbition]

So how will that work re folding the canopy back then?  And what happens when it gets wet as invariably will do so from river water splashes (Other craft and models) or even the rain?  Wouldn't some sort of showerproof material be a better option?

I will seal the cardboard with a varnish or lacquer, as for the rolled back canopy, I feel that I will just make a second version in the rolled up format, so you use one or the other, making a canopy that could be rolled up would i feel just leave it vulnerable to damage and almost impossible to deploy.

[LondonRascal]

Just an idea, i bet you could get a free (or very cheap) sample of the real vinyl used for the canopy from a canopy maker since it is so small. I guess the issue then is, being so small, would it actually want to folder over - or would it 'spring back'. 

[BroadAmbition]

Nice one, Grendel now how do I 'Tick' your post with both a 'Thanks' and a 'Like' ?

Robin - I think it would be far toooo thick and not fold / stay rolled properly and be toooo big.

However unless of course just a small amount was used for effect full width,  folded over only a couple of times - That'd work fine. 

Grendel - I could get onto the chap that supplied the canopy and get a small sample big enough for what you require  if you wish?

Griff, you have the gist of the problem in that it would be way too thick, I did consider this, but really i knew it wasnt the solution, I also considered cloth, but that would make it difficult to handle, I am still not sure how I will handle the rolled up version, as part of that consists of the clear windows, I do have some thin sheets of clear plastic for the windows on the rest of the boat, so it may take a couple of goes for the rolled canopy.

 as an example if the material was just 1mm thick, that would be the same as having the real canopy 1/2" thick, so you would be looking for something around 0.25mm thick (the card I have is 0.28mm, so just about perfect)

Waterproofing the canopy under way using a clear coat, this has darkened the canopy slightly, which I think looks closer to the colour

I spy, with my little eye ....

 

... a Swan Morton scalpel handle and plades.

Not sure what number blade though.

[grendel]

just went out today and bought a box or #15, and a  pack each of 15A, 10, 10A, (Large and small straight and curved) (for #3 handle,

the blade and handle in view is a #4 handle with a #25 blade super strong chopping blade.

If you just use the model in crap weather you'll never have to fold the canopy,  a Yorke should be used to crap weather. 

[grendel]

The rolled up canopy was nowhere near easy, and it's still not lying as flat as I would like, basically I used full curved rails where they would be seen, and the rest are just 1" lengths glued at the ends, glazing plastic added  then rolled up ( not easy where the curved rails are).

[grendel]

next to figure how to make it stay put- I do have some small neodidium magnets that may be handy for that.

[grendel]

and to compare to the real thing

[Lulu]

And you need to make a bowl and Werthers Originals 😁

[grendel]

Front screen hinge pin removed to enable the glazing to be done.

The next part will be a mystery part, here you see work in progress  on the part.

[grendel]

Chipping away at this project, more parts being made on the mill and on the lathe ( this lathe is the little flexispeed I inherited from a very good machinist friend, this was one of two tiny lathes he used when he could no longer manage to get in his workshop, and though small is finely tuned and produces good results on small parts.

Wot - you didn't use your Unimat 3 !

Nope, the little flexispeed is more limited in what it can turn, and would struggle with harder materials, but this task is within its work envelope, and it sits on a shelf within arms reach of where i am working, should it start to struggle with the job, i will naturally escalate to the unimat 3, similarly should the unimat struggle I would escalate to the 13" south bend. the flexispeed is great for small items in brass (the 1" diameter parts I am putting the taper on are about the biggest it will manage, and at that I am needing to restrict myself to about 4 thousandths of an inch cut (0.1mm)

[grendel]

Right, for the next bit of work, I did have to decamp to the unimat 3 and even that struggled, putting  an internal radius on a part isn't easy as at some point your tool will be cutting  all the way round the edge of the curve, the flexispeed definitely  wasn't  having it at all, even going gently the unimat was on the edge of its capabilities, but I got the corners cut in for a nice radius.

Hasn’t anyone yet worked out what they are?
