Perspex + blueprints + modelmaking + 29390 = mess!

Now if someone could laser cut the parts in Perspex (Acrylic) to essentially make a kit, I would be very very interested.

Cutting and trimming perspex is a nightmare in my book.

Tools Passenger Module....

Well.....

I was working on a kit before all the recent silliness, sorry it's a bit dusty. Sometimes the only way to understand a form is to build a prototype. Made from smelly styrene to check fit form & function as a prototype.

I didn't move past this stage but I will if there is demand for it.

Hey Bernie

Hope you're right as rain now....this looks like an interesting lower cost option, I've got a rough pod in perspex that needs work. But a laser cut kit faithful to the plan dimensions would be great idea allowing me to have further pods without sanding off my fingerprints....

Tools Edges....

Hi Richard,

I did have a solution for the edges on both the roof panels and the lower outside edge for the main box shape. Look at the end panel carefully you'll see where the round edge is that there is a place to slot in a solid rod, dib - dab a little filler and it's done. For the lower edge I was thinking to square off the box and use a fast cast edge strip.

Check the illustration.

Tools A little more about using acrylic

One thing I did forget to mention is car filler and acrylic plastic were made for each other. I mean a serious stick together forever type relationship. To pre-form the radius edges on this type of structure it is ideal.

I don't think adding a round corner is beyond anyone here IMHO. The trick is using a long straight edge with coarse paper to knock off the edge first and working through finer grades of wet and dry paper to finalise the shape and leave a decent primer ready finish. It's actually a fairly quick process. If you have to remove larger amounts of tough acrylic whip out a grinder.

Bondo, P38 or any of the similar smelly car filler type compounds are what you need. If you make a mistake just add more filler. If you buy the really big 10 kg tins it's actually quite cheap, always buy at least 2 extra tubes of hardener while you are at the car accessory store, one will be lost and the other will be used when you add too much to the mix to begin with.

The passenger pod is one of my main concern
at this moment, i'm building 2 eagles and
i want at least 4 passenger pods + a Lab pod.

I can't afford a passenger pod at 500 CA$,
and i would need more than one, so i decided
to try to built it from scratch.

As i need 4 of them, i want all of them coming from
the same source.

So i found a guy in my town who has a laser cutting
machine, he can cut from thin styrene up to 1/4 inch acrylic.

He is mostly using Corel Draw and Autocad, fine for me,
i already own Corel Draw at home, so i draw the pattern on
my little spare time, there is no hurry, it's summertime.

And i have the same concern as you regarding the round
shape above the door. I did some tests last winter to see
if the Bondo Car filler could stick to wood, MDF and perspex.

Please don't laugh, this was a 'basic' test, and it sticks ...



The top is clear 1/8 perspex, sides are 1/8 low density fiber panels
and the round shape is a 3/8 pinewood rod.

Don't look at the paint job,i did it on a clear sunny day, with a -10 outside.

As you can see, i don't think you would need to 'knock off' the edge Bernie
if you use a 3/8 round rod.

The AB 44 model passenger pod was an exact copy or cast of
David's original studio model of eagle 1 i think, and i took Wolfspace's
passenger pod (he owns an AB 44 model) and draw all around the edges
on a paper and it fits almost perfect with the above test i did last winter.



As you can see, i'm gathering hints and tips all around to built my
passenger pods, i know that some of you are almost artists building them,
when i look at the pictures Paul took of DX's passenger pod,
i'm far from that at this moment, i'm still wondering how he can do both grooves above the door, it's so clean according to the picture.

BTW Richard, i used the following car filler :

Thumbs up Making Modules....

Hi Neo,

I would say that the way you are going about this you will end up with a first class product. Post more pictures so I can follow your progress carefully.

I am not so stupid that I can't learn from a smart man.

Looking forward to this build immensely

SANJAY!!!!

Good to see you mate

Well maybe I could be persuaded to look at this a little more seriously over the next couple of weeks, it's a fair amount of work though as quite a bit of what I have made so far will need a bit of tweeking at best and at worse redesigning. I enjoy the challenge though so watch this space and those fingers...

Bernie.

Nice job Neo! Im going to start my pod as soon as I get my blueprints...sent several emails...hope I got the right addy for Daniel P. I assume the panel recess is an added panel on top of the other, with the sections cut out, but how did you get the small panel details and door?
