These have taken so much time to do but pleased so far. Just the reinforcing ribs on the top surface to go. Not entirely sure how to tackle them yet so some trials on some scrap bits first. Have a good w/end, Dave.

Back to the turret mods. Muzzle Brake.
Decided to enhance the original one.

Added some little pop rivet bits. This looked worse than what I started with so abandoned that idea and off to the drawing board.

As before I am not taking credit for the machining just the concept and the drawings. Further section was machined off at the diameter of the bit that goes up the barrel.

That fits like so and gives the same amount as original to go up the barrel.

Then the diameter of the top and bottom bits that stick out was reduced. New angles were then machined to get the outside edge to the thickness required.  Hope that makes sense.

That new top angle now gives me the little bevelled edge I was after at the top and bottom of the front face. Then the scrap holes were filled and flatted.

How on earth you machine something to that thickness I have no idea but credit to you guys that have those skills.

That part is now bonded in and gives me the very subtle angle change in the front face that I have seen in historical photos.

Then a very fine skim of filler to lose the join of the two parts. Very carefully flatted so as not to loose the circular lines.

Some 1/32 rivets added to represent whatever those things are on the original pictures. Hope you like, Dave.
