TheGreenknight Posted February 4, 2015 Report Share Posted February 4, 2015 (edited) Hi guys I have been given a gun to partly restore for a friend. What's your best tips for removing medium level pitting or tidying it up a little. Thanks Edited February 4, 2015 by TheGreenknight Quote Link to comment Share on other sites More sharing options...
TIGHTCHOKE Posted February 4, 2015 Report Share Posted February 4, 2015 You would have to polish it out of the barrel and may end up removing so much metal it will be out of proof. Quote Link to comment Share on other sites More sharing options...
Salop Matt Posted February 4, 2015 Report Share Posted February 4, 2015 Lead lapping I belive is the best way but its expensive ! over £100 a barrel i belive. ATB Matt Quote Link to comment Share on other sites More sharing options...
dougall Posted February 4, 2015 Report Share Posted February 4, 2015 is the pitting internal or external? if internal how much metal have you left to play with?Lapping for internal pitting often has to be taken deeper than initial thought?how close to proof is it?....

welshwarrior Posted February 4, 2015 Report Share Posted February 4, 2015 Use a barrel honing machine check the wall thickeness before during and after if you've not got all the tools and knowledge to do it take to a man that can their called gun smiths.

Kes Posted February 4, 2015 Report Share Posted February 4, 2015 It may seem elementary but pits result from corrosion of the original metal in small patches. They cannot be 'polished out effectively -the barrel(s) must be reprofiled and may lose wall thickness to a critical level. Gunsmith's advice on whether enough strength would be retained following reprofiling, If he says 'no' then you have a gun which may be out of proof. Not something to take on lightly I suggest Quote Link to comment Share on other sites More sharing options...
TheGreenknight Posted February 4, 2015 Author Report Share Posted February 4, 2015 I know that at one point it has had new barrels made and the wall thickness is good. I may just give them a good scrub through at the end as he wants the stock lengthening and then refinishing. The action is in pretty good condition I just need to replace the odd spring and a good all round clean. He will just have to live with the barrels. I have shot this gun and it does shoot well so oh well. Then again £30 for a gun that's about 70 year old I suppose he can't complain to much..

dougall Posted February 5, 2015 Report Share Posted February 5, 2015 what are the wall thickness measurements and who measured them?..prior to stock lengthening etc it is important to establish the state of the barrels as always with old guns it is BARRELS/BARRELS/BARRELS which are important...pointless spending time & money on cosmetics if barrels are not safe to fire...why not get a gunsmith to look at them?it is frankly irrelevant it was only £30...that will seem expensive if a barrel fails...a huge number of old guns have pitting,and in many cases totally safe to fire but it sounds to me that you are not sure and if you do not know the proofing margins and barrel measurements/depth of internal pits you are taking a risk...however small you may feel that is it is still a risk. If a shotgun discharge was called a 'controlled bomb exploding within a thin pipe' maybe you would check out the pipes a bit more on basis you & folk stand around them each time a 'bomb' is let off....

TheGreenknight Posted February 8, 2015 Author Report Share Posted February 8, 2015 Took the advise above had a smith give them a once over today and he's was happy that they will do the job well. Quote Link to comment Share on other sites More sharing options...
