Start by breaking open the turret. I took the claw end of a hammer to the spring rest at the back of the turret and popped it right off. Your gun should look like this before starting:
Decide which side you'd like to be able to load from. Since I prime the gun with my left hand, I decided to put the track on the left side. Drill into your turret:
Please notice that the rest of the turret is currently stock. I have not yet bought brass with which to barrel my 1500s.
You'll want to make sure your port is centered so keep that other turret half handy.
Now, you have completed the easiest part of this modification.
Take some PETG, you won't need more than two inches, and a razor blade.
Cut the PETG at an angle.
You do not want it to be too steep, although make it too shallow and you'll have to take out more of the shell than might be comfortable or necessary.
It should look something along the lines of this when done.
Now, take your razor blade and cut a half-pipe out of the PETG.
Hot glue the finished product into the turret.
Now, to attack the shell. You should use the notch cut for the turret as the halfway mark.
I don't have any in-progress pictures of this but the final product should clear it up. If you feel like complaining I did it all with these three tools:
Now, this is what your shell should look like upon completion.
