While shooting my Diana 34 recently... I noted that how I close the barrel can dictate POI shift. A closer inspection reveals that the barrel is shifting in the block... WTF mates? POI is not shifting laterally at all, just vertically. I can tell that the barrel is moving by looking down the top of the barrel block, and noting the position of the muzzle (+/- height) relative to the top of the barrel block.

Closing the action sharply must give the barrel enough momentum to move all the way up it can. Cocking brings it back down. When I softly close the action the barrel does not come up all the way.

I have NEVER had a beartrap, but the odometer has rolled over... (at least 35,000 pellets by now).

Should I just TIG weld it in place?

Is the barrel moving in the breech block?.... or is the breech block not locking up the same depending on how you close it?....

If the former, time to get out the welder, I reckon.... If the latter, perhaps the latch plunger needs disassembly and lube with a good moly grease?

The barrel is definitely moving in the block. The block is definitely locking up just as solid as it did the first shot.

Never heard of such a thing.... Mine appears to be pressed in.... no sign of any setscrews or pins.... Here is the parts diagram, it's shown as one part (you may have to copy/paste the URL):

I think I'd contact Dianawerk.... It just could be that is something that "never" happens.... Who knows, they might just replace it out of good will.... Shocked

I don't reccomend it to EVERYONE for nothing... Faq-U

TBH since the Super Streak has broken in, I would reccomend that also for a higher-powered option.

BOB: do you think they would send me just the barrel unit? Not sure I want a new barrel... I like mine. Unless the new ones come with a front sight.. since my retardness lost that.

allright smartass. 35000 on the original spring? Shocked

i don't have a single gun, powder or air with 35k through it..

my 26 year old 10/22 is maybe at 12000+. maybe...

No, about 20,000 on the original spring. There have been days where I have shot a whole 500 tin, maybe 300 per session. She has a nice (previously shiny, now tar covered) JM spring in her.

35,000? Have you checked the shoreline lately? NJ must be sinking under the weight of all that lead.

Have you taken it apart to see if the barrel will come out? Could you sweat the barrel with solder to freeze it? Is there room for a set screw?

Interesting problem. Keep us posted.

I've taken the barrel block setup off so many times. I think that since the barrel was just press fit (AFAIK it was), it has worked loose over the years. Probably could sweat the barrel in place, but I'm not very good with solder. My hands can TIG pretty good, though.

Since I don't have a drill press, or taps... that's not an option.

I could care less if NJ started sinking. I'm close enough to PA that I could walk there before the water got to my house. 35,000 isn't counting the .20 and .22 pellets laying around. Could probably chalk up 20,000 BB's from my red ryder... Slavia, how many projectiles do you send downrange in a year? (let's assume Slavia doesn't have a shotgun...)

Slavia · Moderator

I average about 15,000 per year, but I send them all towards Iowa. In the last two years I've fired exactly 5 powder-burning rounds, all .50 BMG.

sniper · Silver Status Member

i must be lame. i shoot less than 6-7000 pellets a year and burn powder once every other year. Rolling Eyes

and that might be 300 rounds. Rolling Eyes

.223 is so friggen expensive. (we don't need to get me started). Mad

.50 BMG. you criminal. Laughing

fritz · Silver Status Member

Slavia must not count all the supressed .22lr he uses whilst doing hits for the mob... Shocked

Sniper, I'm sure you're through at least 3,000 on the Mrod already.

Lead is crack for rednecks...
