Success! Thanks to the folks at Jim’s Tap Extraction Service in Torrance, CA, the broken hardened screws were EDMed out of the casting of the Fox Freehead! Also, at the 11th hour yesterday, the grease I was recommended finally arrived. In the meantime, I went on a search to see if the original ¼-20 fillister […]

Just a quick update on the progress on the Fox Freehead before we break for Thanksgiving. I have spent most of the week up to my elbows in various types of grease, trying to clean all of the orifices and metering valves that control the drag on the pan axis. This is proving to be

The Fox Freehead has now finally been broken down to its basic parts. The 82 year old grease, rust, aluminum chips, and most of the broken screws have been removed and cleaned. Simple degreaser was not adequate for this project. It took hours with dental picks, wire brushes, acetone, and degreaser to get all of

I finally made some progress on disassembling the Fox Freehead! Many thanks to everyone who made helpful suggestions. Seven days of soaking the screws that hold the top plate to the Freehead, and many hours of tapping, pounding, and twisting later, I was finally able to get the screws out of the top plate. Thinking

Continuing with the Worrall restoration and clean up, this week I focused on the tilt drive assembly. After much mining of old grease, case dirt, and oxidized aluminum, I was able to actually get my hands on the gears, drive shafts, brake assembly, and backlash adjustment sections. Special attention was paid to chiseling out the

The Worrall Geared Head was one of the premiere pan and tilt tools around the world for decades due to its silent, smooth, and accurate operation, and its ability to support extremely heavy cameras like the Mitchell BNC. When this unit arrived, it had a hitch in the tilt axis and a very large bump

A couple of days ago, Worrall Geared Head #192 limped its way into the shop. This geared head came in with the BNCR #136 that we showed in our last post, and believe it or not, it was in worse condition than the camera. I spent time this week evaluating and disassembling this geared head

All of the work on Worrall Geared Head #192 has been completed! I was able to make the pan and tilt axes run smoothly despite some of the lumps in the tilt axis tracks. Much polishing and cleaning smoothed out the big lumps to a very acceptable level. The pan axis was smooth once all
