viking Posted June 12, 2017 Report Share Posted June 12, 2017 my mate who i go pigeon shooting with has got an old beretta 682 i think it is, he has had it years and whats to have it done up, he is going to have all the woodwork done, and get it all serviced,he was showing me it last week and even though its old when he opens it its reasonably tight but when it gets to the last inch its very slack, no side to side movement, but if you shake it back and forth a bit it seems to be very slack, id guess guns to get slack over time and with use but its strange how its just down at the bottom inch when the rest seems ok, iv heard of people having there barrels tightened but i dont know how this is done, not saying that he would do it himself, he with get the gun shop to look into that, but it just got me thinking, Quote Link to comment Share on other sites More sharing options...
ditchman Posted June 12, 2017 Report Share Posted June 12, 2017 does the hinge pin need turning.........other area can be tightened up by peening......... before he does anything take the barrels off.... hang on your finger...and then lightly tap the barrels with the wood part of the forestock....it should ring like a bell...if it dont the ribs are coming apart and that will cost....£££ Quote Link to comment Share on other sites More sharing options...

Hamster Posted June 12, 2017 Report Share Posted June 12, 2017 Easiest gun in the world to freshen up back to new, as little £120 and no more than £300 for the full monty. Quote Link to comment Share on other sites More sharing options...

Gunman Posted June 12, 2017 Report Share Posted June 12, 2017 You can not just "turn the hinge pins" on a Beretta , You can however get new over sized pins or studs .Theses when fitted to the action will need to have the hooks on the barrels scraped to fit and the possibility that some "blacking down " on to the face . Most O/Us are a little slack in the action when fully open as that is the nature of the design This can exaggerated if the forend is loses . Who ever suggests peening up should banned from owning a gun for the rest of there lives .Any one who does so should be ZXZXZXXZed Quote Link to comment Share on other sites More sharing options...
viking Posted June 12, 2017 Author Report Share Posted June 12, 2017 well whatever is done will be done by a gunsmith i have a miroku 7000 RT-1 probably from the 80's and thats still nice and tight, and when fully open doesnt move at all, when his is open and you were to give it a little jolt up and down it moves very freely, and i have no idea what peening is Quote Link to comment Share on other sites More sharing options...
Gordon R Posted June 12, 2017 Report Share Posted June 12, 2017 I believe they just tap the hook part of the hinge mechanism - in effect squashing the hook out of shape. On Brownings, the semi circle part on the bottom of the barrel. A rather crude and temporary repair. Quote Link to comment Share on other sites More sharing options...
bornfree Posted June 12, 2017 Report Share Posted June 12, 2017 reading it again. are you saying its slack at the last inch of opening if so dont worry about it as long as its tight when closed. Quote Link to comment Share on other sites More sharing options...

Problem is, is when the studs are replaced and the hooks adjusted to suit the metal the bodger shifted will be removed and the effective bearing surface of the hooks reduced.

As the new studs will be bigger the accrual bearing surface will have increased . But as we are only talking diameter increase of .015" it is hardly worth mentioning . Done fair few of these so I know of what I speak . Quote Link to comment Share on other sites More sharing options...
viking Posted June 12, 2017 Author Report Share Posted June 12, 2017 yes its just when fully open, it closes up nice and tight, and there is no play whatsoever anywhere else, just when fully open Quote Link to comment Share on other sites More sharing options...

I totally missed the fact that the larger stud diameter would also increase the bearing surface length of the hook and thus compensating for its reduced width. On the other hand if the bodger hadn't got to it the bearing surface would have increased. Quote Link to comment Share on other sites More sharing options...

figgy Posted June 12, 2017 Report Share Posted June 12, 2017 (edited) If no play when closed leave it alone. The least amount of friction on steel bearing surfaces the better, less wear to occur and Berettas are always slack feeling on opening after a few slabs have gone through them. There is a video on YouTube with Larry Potterfield with a now dead English gunsmithh John f Rowe showing the peening/knocking up of the hook to tighten it up on a old SxS. He also shows renewing the hinge pin and rejointing and putting a gun back on its face. Nice videos to watch link https://m.youtube.com/watch?v=YXbrmmiSngw Edited June 12, 2017 by figgy Quote Link to comment Share on other sites More sharing options...

figgy Posted June 13, 2017 Report Share Posted June 13, 2017 Don't see why not, if it goes wrong some of ditchmans special mastic should fix it. Quote Link to comment Share on other sites More sharing options...
Gunman Posted June 13, 2017 Report Share Posted June 13, 2017 I,m afraid old Jack was past his best when these videos were made ,he learned his craft in the 50s and did not move on . The Americans are a bunch of DYI merchants and know no better and I find Mr Potterfield no better , at times quite scary. Having been in the trade for nearly 50 years I would not dream of doing some of the things I have seen on these . If you want to do any work on a gun then have it done correctly .

JohnfromUK Posted June 13, 2017 Report Share Posted June 13, 2017 Having been in the trade for nearly 50 years I would not dream of doing some of the things I have seen on these . I have heard exactly the same views (but less politely put) from my friends who are real gunmakers; some of the stuff shown by Jack Rowe was a disgrace. I have not seen Potterfield.

vampire Posted June 13, 2017 Report Share Posted June 13, 2017 yes its just when fully open, it closes up nice and tight, and there is no play whatsoever anywhere else, just when fully open It is very possible that it is the metal within the fore end,if it is raised up from wood even slightly it will be lose when open,just remove bend back to shape and it will be sorted.Have done this on a lose one myself that fitted your desciption and its like new now Quote Link to comment Share on other sites More sharing options...
