Dimensions of available springs and where to get them

[evert]

Thanks again! Forgot about that, the dimensions sound like what I want to try in the "Norwegian power" 95..

A quick bump up for this thread to stop it dropping off to where it can't be easily seen (yes, I know we can change parameters). With so much valuable information for reference, I wonder if it might be better to move this to the Useful Information / Tips section, or blend this into the Data Thread?

Yeah, making a thread with all the data we have collected on springs, piston dimensions, port dimensions, compression ratios etc would be very useful.

I'm bumping this thread again, as I've found the Titan #8 to have a tighter ID than what is given in previous charts.
It is given at 13,8mm ID, but the example in front of me is closer to 13,3-13,4mm.
Which affects what guns they fit, as they are said to fit the HW95 by the manufacturer, but the OEM guides I have tested it on are a bit too tight.
Scragging might open the spring up a bit but probably not enough to fit the OEM guide without trimming down the guide a bit.

Useful information again, evert, and it is not the first time that we have become alerted to a discrepancy between the stated and actual sizes, which could cause issues for those of us without lathes. For us, if we're chasing refined shooting manners, a kit by the good folk such as Tinbum, Welsh Willy and ARC has to be the way to go. At least for the more popular models catered for.

I've gathered the info from Protek and written it in the first post.
If anyone finds mistakes feel free to correct them!

Nice one.
