Also over Winter a Breech Block arrived in the mail. A bit more paper work required than usual to get permits following a terrorist attack here in NZ. Firearm ownership all that bit harder now.
I have stripped it all down, cleaned, re assembled and fitted back in the Breech Ring. One difficulty I did have was removing the Firing Mechanism. Had I read the manual properly it all makes sence in hindsight.
Breech Block must be in the Breech Ring. Set Lever to Safe. Fire the Striker Mechanism (this bit wasn't in the manual but it worked for me). Rotate the Striker Mechanism and remove.

Work still progressing with more parts off the shelf and fitted. Each with it's own clean up and restoration as you go but progress is progress. As Andrew pointed out We needed to recover the donut type coupling off the old gearbox and fit it to the replacement. This was done and the drive shaft installed.

Good spotting Andrew. I will recover the coupling off the other gearbox. Ready by Easter lol. I hear on good authority there's another Scorpion that will be at the Easter Rally unattended at nights...... Busy at work is slowing things down currently so aim will be Labour Weekend at yours. Phil

A bit slack on updating but we have installed the engine and had a brief test run. Everything went and sounded good. We used the Ferret as the slave battery. Next will be to finish off the gear box and coolant plumbing so we can run it longer and even try to move it under it's own power. Thanks to Todd who helped with the install and getting it started.

Barrel now back in place. I marked out in more detail where the interrupted screw threads were on the barrel and the engage, disengage marks so when it was re fitted I had a much better idea that it was set up right. Slotted back in and now no need to ever remove it again hopefully.

Thanks for your comments and photo. I hope ours can get to that stage in the near future.
In answer to your question. Unless I really had to remove the breech or barrel then I wouldn’t. It is doable without removing the turret but everything is very heavy and what seems a simple process is, but can take a lot longer than expected.
The breech components I stripped and cleaned on the bench I could have done if the breech was fitted in the turret.
The difficult part I have found with the barrel on the first attempt to re install it was to see where the markings are to engage and dis engage on the breech. Originally when I removed it from the turret you may have seen earlier in this forum that it had seized in place. You could face that prospect as well.
If you were to remove the barrel and leave the breech in place I believe you will need to
- Remove the anti rotation key on top
- Remove the locking plate in the breech
- Probably loosen the barrel stop
- The barrel should then rotate and be able to be pulled out
- I would suggest making makings (paint) on barrel and manlet etc so you know where it has to be positioned to re insert
A couple of diagrams attached.
I have a lot of manuals scanned if you need any further reference material.

Trial fitted the yoke and noticed the bobbin where we had done the weld repair was screwed on the wrong way around so took it off and corrected it. The way it was would have fouled the breech ring lining up properly.
Breech ring now installed. You need to be a pigmy World weight lifting champion to lift an hold this in place to then fix the yoke. With 2 of us in the turret and using a small step ladder we managed to balance the breech ring and line it up (after a longer than expected time). Wouldn't want to do this as a field repair.

XMOD are a fantastic company, I really do rate them. If you have the NSN they seem to have the parts!
Keep up the good work!

Thanks Paul. Yes XMOD fast, efficient and excellent to deal with.

The deactivation of the barrel had removed the recess for the breech ring locating plate so yesterday I marked it out and using a dremel and grinding tool on the air gun I managed to machine a recess back into the replacement piece of steel. Locking plate fitted nicely after some minor further work with a dentist type tool on the dremel.

Whilst everyone was enjoying a Boxing Day sleep in I decided to clean up the barrel and breech ring to see if both would match up. Spent a good amount of time cleaning up the interrupted screw threads as these were caked with grease and grit. Surprisingly once I got everything straight and level i simply wheeled the jack forward, twisted the barrel and that was that. Still some cleaning up to do then hopefully will be mounted back into the turret in the next week or so.

Still, I have found time to puddle on the turret cleaning up threads and going through boxes of brackets to identify and trial fit various parts.
Turret latches refitted. After several re adjustments with spaces to get them to work just right.
External boxes, and smoke discharger brackets. Anyone have the shapped brackets for the smoke dischargers??
Turret hatch bump stops and clamps.
Couldn't resist putting aerials on.

Also I have been slowly cleaning up the turret internals with the plan that if the component was in reasonable condition to clean and refit. If not then a repaint. All back in now including new piping for the periscope washers. Just the machine gun mount to do.
I don't have the turret ring so if someone has one lying about or any othe components you think I need please let me know. Washer bottle, traverse indicator dial, radio gear are also items on the need list.
