Camera Repair - ARRI S

I was the Head Repair Tech for NYU Film & TV for almost 12 years and during that time, one of my biggest jobs was keeping over 90 ARRI S 16mm cameras running.  Up until Summer 2012 the ARRI S was the workhorse of the introductory film class but NYU finally made the transition to digital and while they still shoot a lot of film, the amount of digital projects continues to grow and the ARRI S has been retired.

I may have moved on from NYU but I inherited a massive amount of new and used ARRI S parts and still do camera repair when I have time. Contact me if you are looking for any parts or need some work done.

Analog Projects

The Charlesworth Dynamics site was originally setup to cover the Octopod but has since grown to cover a lot of my other projects as well.  Before I delved into the digital realm, I had a long history of building and fixing things in the real world and I wanted to showcase some of my hands-on 'analog' projects. I felt that this was especially important since I want to continue combining 3D modeling and printing with real-world hardware and hands-on.


Presented here are some highlights of my work in 3D modeling and 3D printing.  I currently have a MakerBot 2X and Thing-O-Matic at home which can print in ABS or PLA plastic. For final prints I typically use a 3D Systems ProJet 7000 or Stratasys Objet Connex500.

Most of my models have been built in Cinema 4D and post-processed with netfabb.

The Millenbaugh Motivator

My latest print - this is a functional piece I designed, printed and assembled for a Hellboy prop replica built by Adam Savage of MythBusters.  Follow the link for the whole story.

Camera Jewelry

During my time as a camera repair technician I saved a lot of broken parts because they looked cool.  After almost 10 years I had a big box of them with no particular use.  I decided to clean up the parts and make some jewelry.  Sold about 40 items and have never had the time to do more.

Camera & Production Accessories

Here are a few camera accessories which I have designed or modified for NYU using our simple milling machine.


The camera class needed an extension added to the Ronford head to accommodate cameras with a larger magazine.  I used aluminum which is easy to mill, the hard part was the precision needed to get all the screws to line up.

Kate's Engagement Ring

I wasn't really prepared when I proposed to my wife Kate so until I could get a real ring I made her one at work.  Since I repair film & TV equipment, the band is part of an aluminum light stand and the 'jewel' is a camera bearing which spins, making it a great fidget ring.  It remains one of Kate's favorite pieces of jewelry.

Stormtrooper Blaster

My biggest nerd project to date has been my scratch-built Star Wars Stormtrooper Blaster.  It's not 100% accurate or 100% done but I'm pretty proud of it.  The original blaster was made from a modified Sterling machine gun but I built mine completely from scratch, using mostly junk film equipment. The only 3D printed item on this is the rear portion of the scope, everything else is metal.  It's more or less finished except for some good weathering.

BNC Cable Holder

I finally got a sweet Panasonic 1760 production monitor for my workbench so I designed and printed a cable holder in ABS which mounts on the side.  It will also work with the 1710 monitor (and probably others) and you can download and print your own via my Thingiverse page.

FOR SALE:  I also have these for sale at Shapeways if you don't have a printer.  See below for pictures.

Poor Man's Iron Man

A little art project made from a photo enlarger lens, broken camera parts and LED ribbon.  It will power something small for never and something big for never-ever.

Focus Chart System

I have been the Camera & Equipment Repair Technician for NYU's Film & TV program for almost 10 years and have finished a few custom projects.  I test a lot of cameras and have limited space to work with, so I designed and built this movable focus system.  It's all cobbled together from stuff I ordered from McMaster-Carr.
