At £24 for a replacement pin it would have been cheaper to buy one or even two guns at auction and dismantle/ scrap for pins, springs, screws, extractors, beads. Ejector springs... in fact everything that isn't a pressure bearing part.... so how sticky was the firing pin.? Quote Link to comment Share on other sites More sharing options...

So measured and made one to same dimensions but a mm longer.👍🇬🇧 Quote Link to comment Share on other sites More sharing options...
Andy H Posted July 10 Report Share Posted July 10 (edited) As you have access to a lathe make one out a shank of an 11/12/13mm drill and harden and temper that is the steel to use, I have an old sxs zabala I have had for just under 40 years but in the first 2 years both pins snapped , Made new one's out of old drill shanks' and no problem's since.

I presume you are using carbon steel drills? Quote Link to comment Share on other sites More sharing options...

The firing pins are 13mm long, striker end is 2.5mm diameter shoulder 6mm and hammer end 4mm. did make one out of 6 mm drill, its firing fine, quite chuffed for making bits and bobs that work, bin the bits that havnt, every day a school day👍🇬🇧😊 Quote Link to comment Share on other sites More sharing options...
TIGHTCHOKE Posted July 11 Report Share Posted July 11 I always used to use No 6 drifts, cut down but left over length. Then fitted and "fired" on an already fired cartridge to prove it was overlong. Then removed and dressed to the correct length, never had one need doing twice. Quote Link to comment Share on other sites More sharing options...
Minky Posted July 11 Report Share Posted July 11 (edited) I'm so glad that there are still some of us out there who have the equipment, the knowledge and ability to do stuff like this. All I get told is... GET RID OF THIS JUNK !!! To which I reply.. IT"S ONLY JUNK UNTIL YOU NEED IT OR YOU WANT ME TO MAKE OR MEND SOMETHING FOR YOU.!!! To which I would also add... I've still got XYZ £ in my pocket... You've got jack in your pockets. I know that there are limits to what you can horde but it always seems to be a case off .. a week or two after something has been thrown out that you need a bit of it and then have to go out and but what you just threw out. Ps. it's nice to know the dimensions of the pins for future reference. I did have a Mainspring break on my No. 4. right in the middle of a day. Undaunted I carried on using the left barrel.

Best steel for firing pins is silver steel, are yours spring return? Quote Link to comment Share on other sites More sharing options...

When the machine you are using weigh's 2 1/2 tons and the chuck is 400 odd mm across and will not hold 6mm stock due to jaw's being ground true over the year's.

Sorry, I thought you were suggesting snarepeg make them out of that size drill. “As you have access to a lathe make one out a shank of an 11/12/13mm drill” Quote Link to comment Share on other sites More sharing options...
