« Part 1: Intro Part 2 of "Parasitic" floor lamp series Part 3: Turret arms »

I’m assuming that the circular turret on the original lamp allows the light box to be rotated. In the original, the turret and arms were made of brass. And since I’m not a metalworker (yet, anyway), I’m making this component from wood.

For the prototype, I’ll be using wood that I have on-hand. Given the dimensions needed and my stock, that leaves me with just cherry for the turret, turret arms, and legs. If the initial build goes well, I may shop for some more interesting options for a 2nd one.

The turret bottom has a hollowed top that fits a matching lipped cap, with enough of a gap between to fit a small lazy-susan bearing set to allow the cap to rotate freely.

Here is the bearing set – it’s about 4” across on the diagonals.

The turret top and bottom were cut on the CNC, and I included a well in each piece to capture the bearing.

With the bearing seated, there’s about a 1/16” gap showing between the top and bottom pieces.

The bearing will sit loose, staying centered by the recess it sits in. The cap will receive a T-nut in its center to receive a bolt through the entire turret assembly that will hold the cap in place. With a little bit of thread-lock, I hope I can get enough compression to hold the cap in place without play, but still allow it to rotate. If this doesn’t work, I’ll scheme a different plan.

To spread the joy of sanding throughout the project rather than saving it to the end, I spent some time sanding the turret parts. Luckily, I don’t need to worry about the interior surfaces.

Next up are the turret arms that will provide joints for the legs to attach. (Connecting arms to legs doesn’t sound quite right, but I couldn’t come up with a better descriptor than “arms”.)

I like that you look into the background of movies. I find myself looking more at the furnishings than the characters. looking for ideas.

It’ll be fun to see how you create this challenge!

In Parasite, the house had such a presence, it could be considered a character in the movie!

Have your say...
