Uprated springs for Revelation Astro 12" mirror cell

[Unicronicus]

Yep, the problem of weak primary mirror cell springs for these scopes still exists, and we are in the hunt for some replacement springs to improve longevity of collimation. Obviously bobs knobs sells these, and RVO are the only supplier in the UK, but they have been out of stock for the past month and we really need these now. Does anyone know what type of compression spring we need to replicate these items because £17 is a lot for three springs tbh, and if we can get these cheaper from a local chandler or something then all the better....

No worries, I found a thread eventually that specified the springs, but for anyone wanting to know, you need three springs with 1.6mm wire gauge, 13.72mm OD, 12.7mm free length, 4.2 coils. Can be bought from spring master or Lee springs.

Anyone who knows what kind of dimensions that you would need for replacing the stock springs of a 8" Meade Lightbridge?
