Title: Shimano Calcutta Conquest
Post by: Lunker Larry on March 21, 2020, 08:46:04 PM
Here's something I haven't seen before. First time opening up one of these reels. Thought it was interesting and I'd pass it along.
It's like an accordion spring type belville washer thingy :)  The two under it are pretty thick and are cupped shallow so I don't think they do much.
Anyway. New to me and kinda unique.

Interesting. I've never seen anyone stack wavy spring washers like that either; looks like seven of them on there.  I just overhauled a couple of large 9/10-weight Ross Gunnison fly reels that had a stack of 5 stainless steel conical Belleville washers.

Wow, that neat Larry. Can you tell how they made it?  is it a series of wavy spring washers with light welds to keep them in the proper orientation? - john

It appears to be made from a continuous coil. I imagine one of the engineers on this site could tell us how it is bonded together.

That's neat!  Thanks for the reply.  There are wiser folks on this forum and I look forward to their thoughts.  I would guess a spring washer of this type would have fixed pressure over fixed compression over distance.

It's called (quite aptly) a "wave spring". They are reasonably common in high-end spinning reels such as the Shimano Stella to provide pressure on the drag stack. I think they behave more linearly than a traditional coil spring, and they compress into a small space at maximum compression due to the flatter "coils".
