EDIT/UPDATE: I’ve since reworked my heat sink grilles to be even more film accurate in design. This picture below breaks it down for you.

Now to build the front "Heat Sink Grille" [emoji106]
Three individual "Avron model kit cylinders" is what I will be starting with. Again "Reade Models" is where you can find them..
It was these cylinders that were apparently used to create the film accurate grille that was used back in '77. Back then these parts were probably put together without to much thought, but fast forward 40 plus years and it's still a bit of a mystery of how they did it.
I did ask for some advice on how to go about cutting and shaping these cylinders. "We just use a band saw to cut the pieces to the correct size, and various files and sandpaper to clean it up. Hope this helps." This is true but again still leaves a lot to the imagination.
So with that and a lot of trial and error..
"Many cylinders died to bring us this information"
To create this grille you will only need the bottom part on each cylinder. This following diagram shows the transformation that I would like to achieve..
EDIT/UPDATE: Below is the old traditional way of building the grille. I do believe that the actual grille is more inline with how I have it pictured above and though..
These are the tools that I will be using..
Two will be cut 6 rings up from the bottom while the 3rd will be cut 7..
The first of the three cylinders I will work on will be the bottom part of the grille. This part of the grille requires the 7 rings up from the bottom.
The thickets ring will eventually be cut off but it should be facing down for this part of the build. First I need to mark off where my next cuts will be (0.805in worked for me) so it fits onto the Mauser..
Before taking this part off (pictured below)..
It's best snip it in down even further. If you don't you risk it breaking..
The bottom front has a bit of a rise so you need to again mark the proper spacing (0.805in [emoji106]). This is where you need to make sure you are cutting into the thickest of the 7 rings..
Then snip it and twist them each off gently..
Now I need to snip off this bottom thick ring on both sides. But only the thick ring itself while leaving the spacer between the rings in place..
It's still not finished as you need now to continue sniping the front. ONLY one more ring up..
Now u can sand this bottom part of the cylinder smooth. Make sure to sand the inside flat so it's flush with the Mauser. Not the front obviously but the sides where it will rest..
