How are you guys deciding your barrels are crooked and not in line?
When I get back to hasting I'll take out the piston and shine a light up the barrel and look through the cylinder and see if they line up. Probly run the lazer level through the bore too. |

I found the small amount that I took off the back rib lifted my barrel even nicely. Pulled it an inch or two at target. But my barrel is strait just facing downward a fraction.
I also put a spacer at back under cylinder where the rear stock bolt goes thru. I think that biggest issues I'm having with groups is my eyes and open sights (this improved slightly when instead of a circle I drew an arrow head and aimed for where I couldn't quite see the tip. The rear blade sight. It literally loses the pin that locks it in. Throws the sight out and usually I don't notice till the sight actually tilts when one end drops totally. Really don't want to be removing any of the scopes or the red dot set up on the other guns and preforming well. |

I am disassembling it again tomorrow to do trigger work etc . Will do another grouping after that
I must say cutting the wonky part off the barrel and shortening it into the breech has made the biggest differences along with crowning the barrel nicely |

Has anyone been able to shoot some half-decent groups at 10m?? I got my gun back together tonight and it's silky smooth so I'm really happy about that, but I'm still struggling to get any semblance of a decent group. Thinking about it as I'm typing - perhaps it is the red dot (Hawke)? I did some sighting in at 6m and got a very tight group initially, but it just went haywire when I went back to 10m. Different pellets are going in completely different directions with a wide scatter. The mount is rock solid, so I'm off the sports shop in the morning to see if he has a Nikko Sterling in stock. There's a very noticeable misalignment between the barrel and cylinder centrelines so there's not much point in fitting the Tasco until when & if I get around to truing that up. The bore looks nice and straight and the rifling also looks good. I must be getting a bit of grease coming through though as I can smell it. Perhaps it's dieseling and causing this issue?

I recon that you guys who have equipment access, should do what you can with accuracy of the gun basically using the parts provided, but when you got that done, keep the stock and barrel and have a bit of play just totally rebuilding it with parts you make and maybe design yourself.
Post it all up here for the envious to see. (such as myself) When I say rebuilding it, I mean if you want to turn it to pcp so be it. If you want to strip it out and make weihrauch pression pieces for it so be it. We can all jump in on the getting it shooting better, but remaking a rifle would be an interesting thing to observe. |

Well, no shooting tonight either. I thought I had everything ready for reassembly, but I still couldn't get the cocking shoe located through the slot and inside the piston where it should be. I did some measurements and figured that I'd managed to shrink the centre swage on the piston even more when clamping it in the lathe leaving too little clearance between the inner wall and the spring. The next move was to thin down the shoe, but that still wasn't enough. I managed to find an old piece of pipe of a suitable size, cut and machined it to suit then pressed it inside the piston to gain some clearance. This worked OK, but of course opened the slot up more allowing one leg of the shoe to be free to disengage if it so chooses. Out came the files and a slot created on the leading edge so when the cocking pressure comes on it should be firmly locked in place. Test fitted before I packed up and looking good for tomorrow night. I really hate the piston design, construction and the material they've used. The only good thing about it is the centre rod which appears to be hard as hell. The tube itself though is very soft (tapping the slot edges true with a copper head hammer after I'd spread it left visible impressions in the 'steel'), the extent of the swaging is far more than necessary and the cocking arm slot is too wide. It's a shame because the cylinder is really quite nicely made. I'll persist with this part for the time being so I can at least fire a few more shots, but I may yet resort to making my own from a piece of pipe and utilising the original centre rod and base. |

I originally had a lift-off TIG which I really struggled with. Updated to a HF start model and what a difference it made. I'm not very proficient with it but it's great for a lot of jobs where the MIG is going to leave too big a bead.

There are thousands around Cambridge.
Ive shot about 420 since March, which is only about 6 months 😳. Planning on going back to the bunny factory in the next few days, should be another good night. |
