Dome - Panel Movement
#1
I'm just starting to attach my dome panels so I can do the final body prep before painting. I saw files for an awesome set of 3D printed dome hinges designed by Helmet on the R2 builders site. But, they're designed for use on an aluminum dome and the geometry is off a bit due to our thicker panels. I had to modify part of the hinge to get them to fit. I'm going to reach out to Helmet and see if he's ok if a share the modified files to complement his standard files.

Helmet's website


Helmet's designs also include this inner panel structure piece.

Helmet recommends that you pre-bent the inner structure with a heat gun but I had no issues with just clamping it in place as the glue or the weld dried.

The printed hinge parts:

The hardware: (Half from McMaster and half from the hobby shop.) Helmets files include all the hardware part numbers.

The finished installation. The spring allows the pie panel to "Flex" if the panel stopped or pushed.

Thanks Helmet for your awesome design!

Have a look at these hinges.

I found them easier to mount and feel more stable.
But that's just my opinion :-)

I like the simplicity of the ones you linked to, but I can see the spring hack on this one being useful (especially if doing events - damn kids can't keep their hands off anything =)

You could still put the springs on these ones as well, but they fell more solid when you are opening or closing them, I found the other ones had a bit of side wobble due to the two thin arms between the hinge point and the pie panel.

I’d be interested in your modified hinge design. I just received the parts from McMaster and Dubro.

Cheers

Looks like it's time for a remix!  Devil

What modification did you have to make to the hinge?
