LSS...your pics only show as icons with a X in the centre...suspect that's where the Photofkt remark comes from...

Still? Can no-one see them?

I moved them to Google hosting. Maybe your server blocks Google?

Please let me know if you will still be letting go of your old one once you find an upgrade.

Hey there fellow cave dwellers,
Well I finally got around to making the thing that inspired me to get my lathe in the 1st place.
At the time, I had gotten hacked off at how much a shop wanted to charge for an extension tube for the shottie, it was like a R1500 for a +2 extension kit.

Background
I shoot (IPSC 3 gun - Standard Manual division) in a shotgun match the victor is the brother that can load the fastest (the main issue)  and shoot quick and straightish but if you can load an extra few rounds that can be a differentiating factor - here's video of some typical stages


The project.
It always stayed in the back of my mind so when ever I find a bit of tube I think, mmm.
This weekend I picked up an offcut of curtain rod and I had a bucket of shot gun doppies right there so I dropped one through the tube. It fell through smoothly and so it began..
the little bit of tube took 4 doppies - Perfect
I turned a mild steel plug for the end and tapped a hole for a grub screw to hold it in place.
Then I made a 2 position cutter for the thread from a broken drill bit. The one on the end is for the external thread and the one on the side is for the internal thread.
The thread is 10 tpi and very shallow with a square profile.
I cocked up the 1st attempt because the tool moved in the post and I didn't see it.
I was pretty chuffed when the end cape screwed on after the 2nd try.

With the tube bit done I needed to make a "jobbie" that was threaded all the way through on the inside.
The "Jobbie" threads on to the existing tube and the extension screws into that.
The challenge here was that the cutter I made could only get half way down the bored out bit of alu bar stock.
I figure that is was 2 separate threads so I did one side then flipped the peace and did the other.

It went on the gun as planned so I grabbed a handful of rounds with great anticipation and started feeding it.
... it stopped very firmly at 7 rounds  ???
The follower was catching on the inside edge of the new tube.
I hadn't measured the ID  ::)

With my longest boring bar held in the post with the maximum sticking out, the overlap on the cut form each end of the tube was about 1mm.
After many light passes... lots of flex
Eventually the follower could slip all the way to the end in hindered.

Put it all back together again and it swallowed 10 rounds in the tube  ;D ;D ;D
But... the last one didn't feed when cycling - spring in the tube too short.

I got the other shottie I skollied for free from work, a Winchester Ranger 120 - the parts interchangeable with my Defender 1300.
I yanked out the spring and it's the same length as the one for the 7 shot tube on mine. I chopped a bit off the end and lassed it on to the end of the other spring.
Problem solved.

So being on a plak I decided to change out the barrel from the Ranger it's about 10 inches longer than the defender one which is 18 inches.
The lug is in a different place because that it only has a 5 shot tube. But with a spacer it fits fine.
It's all ready for a test flight at the range.

Side bar.
If anyone knows where I can get a choke system fitted to the barrel please let me know. I do need to shoot slugs on level 3 matches so
The Picadilohead that had it before friggin sawed the tip of the barrel off with a hacksaw - not even straight.
It had a winchoke system but that's what he cut off.
In the meantime the longer barrel makes it look in proportion and I should at least get higher velocities from an extra 10 inches of barrel.
You can see the short barrel in the pic. The piece between the Knurled "jobbie" and the forend is the spacer.
Life ....  when I was younger I had all these cool brave quotes and tag lines .... then life happened  ... and I have no socialialy acceptable  words 😶

I recently upgraded my lathe a little.  Fitted a quick change tool post and a decent DRO.  Makes duplicating parts an absolute breeze!
I came here to drink milk and kick arse!  And i've just finished my milk.

Had an HXX GCS900-2D DRO fitted previously that was an absolute waste of money.

From those four tool you show, I might use only the one third from the left.

Jughead, why are they mounted to the left of the tool holder?

That's the way the quick change toolpost works.  Some on the left for facing, others on the right for boring. Here are the tools mounted in both positions.

Do yourself a favour and do not buy the cheapest you can get. HXX is a total waste of money.

I eventually bought a SINO SDS6-2V.  Cost was around $230.  I kept the HXX scales and just adapted them to work on the SINO DRO.
