Cutting coils?

Trebob

I'm wondering if cutting coils off a spring to bring down the Fps will do any damage. Or is it just a case of wearing the spring down quicker because of less coils.

If i remember correctly place the cut end of the spring to the spring guide, also cut the spring so there's no sharp bits showing

Can I just file it down to make it flat like the same as it was before. Also does it have any effect on the spring? Cheers in advance.

I've never filed it back but im sure it wouldn't to any damage if its on the spring guide side of it, it shouldn't cause any further changes to the spring apart from reduced power Rob

There is nothing wrong with cutting the spring, but you do have too leave the spring long enough that it will return the piston too the correct position.

I have received a couple of badly downgraded aegs, where the retailer had literally chopped the spring in half. This resulted in the piston teeth being shredded when you fired it.

Now this is my own experience and I know others do the same, if you snip a few coils off you need too debur the cut and flatten the cut end of the spring as much as possible.
Make sure the cut end of the spring goes inside the piston!

The reason for this is if you put the cut end on the spring guide, as it compresses when fired the cut end can open up a bit and get caught over the spring guide, which in turn jams the piston on top if the spring guide.

I have personally removed spring guides, spring and piston all stuck together on several occasions!

Yup - as Rook said, inside the piston. Personally if I'm cutting springs I bend the coil inward with a pliers, file the cut and make sure that it cannot possibly bind on the piston head no matter what. I have seen many springs wrapped around spring guides, and unfortunately I too have seen ye olde half-of-spring pre-engagement.

It is no an exact science, but the rule of thumb I use is 0.06J per coil (not including the flat/first one), and not more than 5 coils.

Everyone has their methods and preferences. It does no harm to snip the spring however the best is still a full length spring of sufficient power for the gun

Ok lads cheers for advice. I cut the spring maybe half a coil and followed all your methods and brought the power down to a legal power everything seemed fine until a skirmish yesterday! While out the first few games no problem untill about the 3rd game. The aeg decided to have a couple of jams which I sorted in the usual fashion:) what started to worry me was not only constant jams a whining noise from the motor appeared and the trigger started to get quite stiff. So this led me to wonder was this the spring I changed Did i do a dodgy job maybe. Or is this a whole different problem do you guys think stiff trigger,whining motor and jams.

Or was it just the cold cold weather. Also the gun is a G&P moe so I would of thought that this stuff shouldn't really happen to a quality aeg no?
