Greetings! Here’s a new Space Tanker I made:
P.S. Props to Wayne Hussey for the idea of using 1 x 2 axle bricks and
Technic axle rods to connect the modular sections.

I was gonna ask about that actually - was there a reason you chose axles
instead of pins? Maybe because you found pins werent strong enough to hold
the complete ship together? It’s just that I seem to have accumulated an
over-supply of NxN bricks with pin, and would probably have tried them first,
just to use some of them up!

First I want to jump in line about how awesome this ship is! WOW! Great job Dan.
Glad to *help*.
In answer to the pin vs axle question - With lots of models, the pin connection
is just fine. Better with NxN bricks with pins than Technic bricks with pins.
With Technic bricks, the pins are loose and not necessarily aligned for best
connection. With both NxN bricks with pins and Technic bricks with pins, there
is a definite force to be applied to the pins in order to get them to begin to
engage. This causes jarring and sometimes the need to twist the parts a bit to
get them to start. And when you try to take the joint apart, there is a *snap*
at the end of disengagement that again jars the model.
If you jar a delicate (or even not so delicate) model enough times, the model
comes apart in unpredictable (can you say *catastrophic*) ways. Also, if you
have ever tried to push together (or pull apart) a model that needs more than 4
joiners, the force becomes extreme.
I have built models using my *patented* joint mechanism with as many as a dozen
co-planar joints. The model *slides* together. And it slides apart. The friction
will usually provide enough resistance to hold your models together.
You can test this yourself. Try to align 8 pins (separated on the plane by a few
bricks or studs) at the same time, push the assemblies together and pull them
apart. Then use the axle method with the joints in the same locations and see if
the forces aren’t easier to work with. The major difference will, I hope, show
the benefits.
There is a cost. With NxN bricks with pins (or Technic brick with pin), a joint
can be as small as a 1x1 or 1x2 (on each half). With the captured axle joint,
the size is 2x2 (on each half).
I have posted an image of the parts I use to make a *captured axle joint*
here (post moderation).
The green and yellow half of the joint holds the axle from moving. The grey and
blue are the capture part. You can put the grey brick with the green/yellow to
make the joint *softer*.
Again, Dan - great job! I wish I could borrow style as easily as we can all
borrow technique!

| (...) A-Ha! I couldn't figure this out until I realized that the axle is actually part 6587 - Technic Axle 3 with Stud. Now it makes sense! clever! -Rob A> (19 years ago, 8-Sep-05, to lugnet.technic)
