- Join Abi from the Dawkes workshop as she takes apart this Edwards Bass Trombone valve section which features two Axial flow (or Thea style) valves. These units are modular and are designed to be taken apart in sections.
Abi discussed the modularity of the design, some important facts about cleaning and maintenance of these valves and we also get into some slide cleaning.

Abi did a fine job of showing and explaining but she earns bonus points at 8:50 for mentioning "making it easier for the next person" to take apart by doing preventive lubrication. If only more technicians would be pro-active about doing things correctly, many repairs and maintenance tasks would be simplified and ultimately, save money for the customer.
Thanks for your knowledge!
Thank you for sharing this comprehensive video about maintenance of the Thayer axial-flow valve ! I think this video should every bass trombone player benefit from seeing at least the ones whom has got Thayer valves on their horn.
This was so cool to watch! Thank you for a fantastic video!
Glad you enjoyed it!
First, thank you for share this video and spread this techniques for free!
In 14:50 Abi said that she used a "foam strip to polish".
Can you inform what kind of foam is? Brand, specification... Any kind of information is welcome!
Thank you in advance!
Hi - Thanks for your question. The details are in the info button in the top right of the video, there is also the link here to the product: www.dawkes.co.uk/diamond-backed-flexible-abrasive-strip-400-grit-300mm-x-25mm-strip/17724
That green stuff is VERDEGRIS which will occur on any copper based alloy - copper, brass and bronze. Brass is copper and zinc, bronze is copper and tin. Verdegris is actually quite poisonous if ingested. I suggest using a face shield when removing it. Great video. Thank you. Ian
Face shield unnecessary as long as you don't suck the verdegris out of the tube. Been repairing brass for over 20 years and never had a problem with it.
