Seydel 1847 Slipslider Project

Anything apart from the two mainstream default harmonicas (Solo-tuned fully-valved chromatic, and un-valved Richter 10-hole diatonic). Alternate tunings, different construction, new functionality, interesting old designs, wishful-thinking... whatever!

Fascinating stuff!
As I explore embedding magnets into my 3d prints for more than just fastening and mounting purposes, I’m sure there are going to be a lot of options that I just hadn’t considered. Great work, Dominick! I’ve got some initial reactions that I think might be useful, but I’m trying to flush them out a bit in my brain before I respond. Hopefully we can chat about it sometime.
Cheers!

Belated thanks for your video, Dom. It certainly shows that your ingenious assembly works to alter draw reeds pitches in the Seydel 1847. The magnet spring back is cool, and the fact it works on both blow and draw reeds is a first. Well done!

BTW I sent your demo video of it to Jim Antaki and Seydel, with positive words 🙂

Bertram Becher came up with a much more limited approach to the magnetic draw bender for his own use. He installs it in his Big 6 harps, specifically to lower just a couple of notes. He kindly gave me a sample; here's a photo.

Brendan, this is similar to Seydel "All Minor" harp as far as I understand.
This is something I'd consider to switch between Paddy Richter / Richter / Country tuning, if only I

1. played Seydels and not Suzuki with phosphor bronze reeds
2. didn't have nice shiny promaster gold coverplates which I really don't want to drill :)

The first one probably can be solved by gluing micro magnets to the middle of the reed - so it doesn't affect the pitch by itself but allows reed to be moved by magnetic field.
