Dalek Bill Dalek Dirk The Scarf Mod


After some experimentation, the dome construction method that works best for me has been the fast machee and spackle method (I'm fibreglass averse, but also like to do things myself). Bill's dome was made of newspaper, and I didn't get a very good bottom edge. The new dome is still not perfect, but much better than Bill's.

Bill's dome plug was a 1/2" too small, so I made another one. this time I drew a circle on the base board of the right diameter and made sure that the template stayed on the line as it rotated.

The key with fast machee is to use it stiff, and give it plenty of time to dry: a week to 10 days is needed. I've had domes warp if they're dried too quickly with a fan heater.

When spackling the dome, I went around the lower 3" of the dome with a straight edge, which helped keep the surface nice and smooth.

After sanding I sprayed it with a heavy wall primer (Kilz brand in the US) and then used automotive primer and paint over that.

In case anyone's wondering about the strength of a fast machee dome. Here's a picture of me standing on one!

Mounting The Dome

With Bill, I used the classic centre pivot method to mount the dome. With Dirk I decided to go for a pivotless dome, to give me a little more headroom, as I'm a little over 6' tall, and Bill is cramped inside for me.

I stacked up two wooden rings, cut on a router so they are perfectly circular.

The top of the neck bin has the conventional four aircraft wheels in a vertical alignment, but also four additional wheels in a horizontal alignment
to stop the dome from moving sideways (instead of the central pivot). They're positioned so they fit exactly inside the larger ring.

I mounted the eye pivot platform slightly above the disks on spacers to give the brackets room to go underneath it.
This allows the dome a full 360 degree rotation (at least until I trail any wires downwards(!).
The brackets I used were L-brackets and were too long, so I twisted them in a vice and mounted them at a 45 degree angle.
If I was doing this again I might make the hole in the top of the neck bin small enough so they fit right.
