Done my bit for the BBS: http://www.airgunbbs.com/showthread....-being-a-mod-… now I’m a game-keeper turned poacher.
That's a bummer ! But thanks for reply.
I struggled for about half an hour free hand and thought now is the time to get on the forum or come back with a fresh head.
OK THE EASY WAY TO GET THE BARREL LATCH PIN THROUGH.
Push the barrel plunger in on the corner of a work bench and stick your punch thru ( exact size is good here)
Then mark the punch with a scratch or blade pull it out about another 2-3 mil and cut it off on the scratch.
Push the off cut back all the way in so it doesn't protrude either side .
I held the barrel in a vice whilst doing all this and used a normal hacksaw for cutting the punch.
You now have a slightly shorter punch and a vulcan barrel pin tool .
The next bit is easy just line it all up and hammer the pin through.
So thats all good but the gun will not cock ! I seem to be coil bound the spring i used had about 40mm of pre load and now under full compression in would need the piston to go back at least another 10mm to latch on OH BUM !!
After the previous engineering triumph I decided taking it all apart again to chop the spring is tomorrows job.

Anyone know how much pre load you can have on a vulcan ?
The spring I took out looks in perfect condition but there was no pre load at all and I have read in a few places that there should be ?
Cant say for certain that the spring I took out was an original.
I have used a spring that closely matches a titan number 8 ,the size often recommended for vulcans but would need different guides to a standard spring .
There was about 40mm pre load I was using a compressor so got it in without much fuss.
So I have had the guides made for this spring and on checking I can see the guides are not touching so it has to be the spring it looks completely compressed inside the piston .
I slot the cocking Lever in and just kind of close the barrel as if the pin was fitted.. Then push the barrel into place so that the plunger depresses against the latch pin, then you can tap the pivot pin in no problem. I guess it must be a but of a knack, but I can do these with nothing but my wee hammer.

Hi Donald I did start of that way had it all back in a sash clamp with straps to try and stop it moving sideways as I pushed the spirng loaded evil thing in but everything kept moving .
That's when I hit upon the other idea and it was, easy that, way .
How's your exorcet BTW mine is really good favorite gun at the moment .
I don't like it. Too hard to cock, inaccurate and jumpy. But it's my dad's gun. I'll talk him into letting me sort it for him.
Only thing is the lathe is on the blink at the moment and there's too much else happening. It'll get the treatment at some point.
How's your 35? You ever get it accurized?
Donald
Hi mate yes the 35 is perfect now accuracy wise, still a bit more twang than I would like but I am too stingy to buy it a straight spring 🤣
In the end it was brand new shims that did it.
Sounds like you need to get on with that exorcet mine is really good same accuracy as the 35 !
