Good photo shop skills.:thumbup::D
Id go 5mm over min legal length as your insert is short as so you gain nothing by extra length except perhaps smoother swing which is sort of irellevent in this case?
Is min length 762mm?
762mm is minimum. Make it 763mm with a full-length 9mm barrel pinned inside the shotgun tube. Probably best to do in a 20ga or similar as a 12ga with a 9mm tube filling it out might get Heavy. Also make sure the action can take the pressure.... pretty sure SAAMI max for 9mm is much higher than any shotshell cartridge
For the love of god don't put a damn VFG on it
Yup just checked, 762mm, think I'll go 800mm still
righto I'll loose the grip
I've seen it done before on a 12g with a 6" section of .38 special barrel inserted at the breach end, then the remainder of the 12g barrel was turned into an intergraded suppressor with baffles added. The rimmed .38 case is easier to extract, and all that was required was an extra bit braised onto the existing ejector/extractor.

Laser the barrel off Toby, cleaner finish, Grinder should crown it just right, Hacksaw, then file? or turn in lathe:wtfsmilie:
I went for the work out approach.
I sanded the burrs of the outside trying to keep it flat and used a small chainsaw file to take off the burr on inside of the barrel then a bit of sand paper

There's probably a way to do it without taking all the bluing off
Im impressed he got it pretty square!:thumbup:
Gave the barrel a quick sand and de grease then measured up how the steel bar will be placed. Used whatever that thing is to get the contour of the barrel so I have an idea how much to grind off the bottom

Just got a cheap $25 rail off trademe. Will wait till it arrives and see how long the screws are on it so I know how thick the base needs to be.
Good stuff Toby, you have restored my faith in the young again. That you are active and making your own 9mm and not stuck to your play station (the electronic one, not the one you were born with) shows great promise for the future.
We need more young lads like you!:thumbsup:
Guess what's been pulled apart and can't be put together again :(
I'll keep at it should come together sooner or later stupid springs are bloody hard. At least I have a rough idea what goes where
Toby, I'm notorious for taking things apart and not getting them back together again :D
Digital camera is your friend. Take pics of each sequence as you work, much easier to visualise how things go together.
I have most of it sussed now. One spring left no more pins left to put in place. Just have to compress the bugger somehow and slip it in its place and hope I set the trigger/hammer up properly or it'll have to come apart and try again
Here you can see the hammer comes back I can feel it locking then when I pull the trigger it releases so it must be done right just need to get the spring in, any ideas? I have tried ramming it in ended up with skinned knuckles :D

Toby,there may be a hole in that shaft,compress the spring then slip a small Allen key or nail to hold it then slip into place and pull out nail
Worked thanks. A few failed attempts at using the vice to close it but ended up coming up with an idea that worked then had 3 attempts at putting it in. First one I found out I put it in upside down so took it out compressed the spring again put the nail in then went and put it back upside down again :cave: #rd time the charm. Gun works again now though doesn't feel as nice as it used to might pull it up part one more time and move the spring around a bit see if that changes things.

Ahhh, nothing like sawing a shotgun in half for the first time!
Looking good, but I'd personally be looking at shortening and slimming down the forend as the proportions aren't quite right now with the short barrel.

Think English "rook rifle" and you'd know what I mean
Had to google those. Not sure if I will cut it back now that I think about it. I have stupid long arms and like being able to hold the gun out a bit further out
Well the rail was at the door when I got up so that was bloody fast. Now to find a way to mount it
Its coming along nicely Toby. how do you plan to fill the gap between the 12g barrel and the 9mm barrel.
its just a chamber insert so not an issue,
Righto guys I'm quite proud of where I have got to today. Can say its shaping up. Went out to our scrap metal pile that I half ass made a year ago and grabbed a cut in half digger bucket and cut a bit for the rail then tapped it and well yeah pics tell the story.
Might also add I pulled the gun to bits again had a good look and put it back together a bit different and it works like it did before doesn't feel weird anymore. Quite happy I went with my gut instinct and rec checked it or could have been bad later down the track
