Diana 52 spring guide

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi,
I just made a new spring guide for my Diana 52. It was my first attempt at making one. I think I may have made it a bit too tight. It was quite tight to get the spring on for assembly.
This is the change different in fps before and after

RWS Super Field 15.9 gr
Factory guide = 825 fps (24.0 fpe)
Custom guide = 770 fps  (20.9 fpe)

Is there any problem using it like this (other than the loss of power)? I wondered if the spring might be putting too much pulling force on the guide and break it.

The up side is the twang is gone, it must be quieter now as I can here the pellet flying through the air now, where as before that was mostly masked by the twang

	What did you make it out of, metal or delrin? I know when I got one for one of my guns I thought it was incredibly tight, but remember that the measurement inside the coil increases as you compress the spring. So maybe under a bit of pre load and cocking it actually fits really well. I would say put heaps of pellets through it and see how it goes, it is probably a bit tamer to shoot now anyway.

	You've done well! The spring guide needs to be snug in there otherwise it does nothing. Now the twang is gone this means less vibration and hopefully better accuracy. Speed is not everything.

	the spring guide should be a nice tight fit, when you cock the gun the spring compresses and the inside of the spring will get bigger and yes it will quieten your gun down a lot! :) thats why people get the tune kits. I would put 50 shots through it before you put it over the crony again. Give the parts a chance to settle in again and then see what it is putting out.

	Thanks Guys, I wanted to have a good go with it tonight, but I got sucked into trimming horse hooves. So I managed to shoot about 20 pellets through it before it got dark.
