Good Morning All,

Looking for a Sako finnfire ejector spring please?
Mine has pinged out and lost in the grass somewhere.
 
These can be made without much trouble using .7-.8 mm piano wire and some pliers. However, its much easier if you have an old one as a pattern.
The attached diagram can be used at a push if you dont have the old one to copy and can't locate one for sale.

You can still buy original ones from GMK but I have one spare that I made (as well as two original).
PM me your address and I will send you the one I made.
 
You are welcome.
GMK is a dealer for Sako in the UK.
The one I made is probably stronger than the original. The only issue is how to post it without getting damaged in transport.
 
How spooky is this?
I made some ejector springs for my F/fire1 following Alantoo's diagram in this thread in 2016...

sako finnfire p94s

Hello people Does anybody know the dates when sako started making the p94s finnfire hunter so i can age my rifle Many thanks Ben

My bolt has always been a bit stiff to cycle since then and it reminded me when out on rabbits last night... so today I decided to have a close look as to why and reckon it was because I hadn't got the vertical to horizontontal bend at the back end at 90 degrees ... so, of course, I had a go at it with a pair of pliers and fractured the wire. Merde 😱

Just made another with a pair of long nose pliers rather than the aero modeller type wire benders and it was dead easy.…. It works but having just seen the dimensions in SCC’s post above, I can see there’s an extra bend in the wire… so, I’ll have another go whilst the action is out of the stock.

cheers

ps... Hmmm, at the moment I'm not convinced about that 6mm dimension... just made one up and it fouls against the face of the bolt so I need to take it out again and measure it to check I've got it right.... Alantoo's diagram shows that as being 0.190"/4.826mm.
pps... Reduced it to just under 5mm 'inside' the bends and it's fine :cool:

Just a note to the drawing. The oroginal springs are made from 0.6mm wire. 0.7 to 0.8 piano wire will work and probably last longer.

You could be right. My diagram was not precise. Just a rough estimate in case i ever got stuck with no spring to copy.
 
And the 6mm bit is more like 5mm. If you use 6mm and thicker wire you may have problems with closing the bolt.
I made mine by comparing it to the original springs I have.

Ahh, that might explain why my cases were ejecting around 5m with my newly made 0.8 wire then! ...i had to reduce one of the bends to tame it down some.

:lol: Almost as good as hot cases flying down the shirt of the lamp man sat next to you when shooting out to the right with a 10-22..... he started sitting on the left after that :p
 
Would you be willing to make up a few more @safer ? We have 2 P94S and both have weakish ejection. Happy to pay whatever you need to get plus postage.
 
Hi all
I thought I had some wire left but I don't. Don't despair, I have ordered some more. It will be few days before I start making any so be patient.

#zerovarm - If you spring is not visibly worn out and not broken you may be able to just tweak yours. I will send you some spares before you try that because (as this post started) they can snap when you try that.

I don't do this for money so I don't want any. Pass it forward. Donate whatever you think they are worth to you to the good cause of your choice.
I will be in touch as I make some in order of your request posts.
