Hi nunga
I ground the existing sprung pin to have a shallower angle. I also noted that the crusher and Diana have a different  type of fixed pin. That is the latch pin contacts a circular surface. A ball bearing on the Diana and a round bar on the crusher. This seemed better to me. So I modded the fixed pin in the compression tube to have a semi circular surface. I could not remove the pin to make a replacement so I added a spot of weld with my tig an then filed and sanded it.

Hi novagun,
I got the pic of the steel one from the UK john knibbs web site. £6.50 + p&p
A brass one would be nice though. Easy to solder or braze the pieces together.

That trigger guard trigger guard has been on my mind. The way I have taken all the black plastic off my Challenger makes the the black guard look out of place. A Brass one, not polished might look good.

so what you are trying to describe is you made a new pin latch with different angles?

With the crappy weather over the weekend I have done some more work on the Gamo Hunter. I put the stock back on and fired a couple of shots out the porch, only got 500 fps with jsb exact .177s - bugger.
So I took it apart. Seal stuffed. Put a new seal in. Now got 800 fps much better but not awesome. Breech seal looks ok, Hmm, I'll have to try a different spring or a gas ram.
Then I noticed the barrel was not locking securely in place. Just waving the rifle around or a gentle tap on the barrel was enough to make the end of the barrel drop a few mm's. This will not do, I thought. Google is disturbingly silent on this topic. Oh no I'm going to have to think for myself like the old days.
I can see 3 things that could cause this problem.
1. The latch spring is weak.
2. The latch faces have worn.
3. The barrel lock up in place has always been crappy.

I decided that angle the latch faces meet (due I expect to 2 and 3 above) was wrong and made it too easy for the latch to pushed in.
I think I will need drawings to explain, but I ended up modifying the angle of the spring latch in the breech and the shape of the fixed latch on the front of the compression chamber.

Now it's sweet as, the barrel/breech stays put until you give it a firm slap to break it.

Interesting , I had not heard of the solder, but I had heard of the Al brazing rod, but I didn't have any of that either.

One of the problems with welding small parts is that Al melts at a lower temp than steel so you can't tell by the colour when it is close to melting temp.
Being a very good conductor of heat the first you know is when almost the whole part turns suddenly into a slumped mess. Guess how I know Embarrassed

Thanks for looking Nunga, but no, I don't really need another guard any more.

Oh by the way i did not have a trigger guard. If you no longer need it might be a good idea for me to move this topic over to the technical section as there seems to be a lot of good information here.

You can also get silver solder wire that has a flux core and can be used on aluminium with a large soldering iron. You also need some oil and some flux paste. You put oil on the surfaces that you want to join and abrade them through the oil with something sharp. The oil prevents oxidation. You then drip melted flux onto the surface. This displaces the oil so you now have flux coated, oxide free, aluminium that can be soldered with the silver solder, which I think Jaycar stock. ]]> Thu, 01 Jun 2017 17:33:14 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=351&PID=2121#2121 Gamo trigger guard : The tabs are TIG welded from the... www.kiwiairgunners.co.nz/forum_posts.asp?TID=351&PID=2115#2115 Author: xyon

The tabs are TIG welded from the back, because my Aluminium TIG skills are not very special, it's a bit rougher looking Tongue
