Hi Pierluigi and Cedric!
Good to see that my posting has inspired others.
#1:
I used an L-shaped drill...
NO I didn’t! 
I used the other sprocket as template and marked the bolt holes position and drilled the holes from the outside.
Then made the countersinking with this Dremel bit, working as vertical as the sprocket permitted...:
Superglue the bolts, cut the ends + epoxy putty.
#2:
As the studs diameter grows when I made them "my way of" castle nuts so the countersunk is made 5,5mm.
#3
This is a tricky one as the sprocket s are now painted an I cant see how much I added to the triangle shaped hole.
But here is some measure that might be of help for you.
Please note the comparison with a real Panther sprocket.
Not perfect but a good bit better as the measure 14,5mm is made far too small in the kit.
Kind regards
Kent

Hi Cedric and Kent,
many thanks for your posts
@ Cedric
I suppose the thinner drill bit pass through the hole in the outer ring to reach the inner one to pierce it. But working so the holes on the inner and outer rings have the same diameter; because the bolts are countersunk how did you work to enlarge the hole only in the outside face of the inner ring?
Have you worked on a bit larger brill bit by a lathe to get a thinner tang to pass through like the other bit?
(my English is not brilliant
and the technical one is worse so I hope to be understandable)
@ Kent
# 1 :
I think working by the ball-shaped head you get a conical countersunk hole. Am I right?
#2:
ok, I will make the 5,5mm holes.
#3:
the measures are useful; I will cut a stencil keeping in mind those. (May be your work is not perfect but I like it very much).
Kind regards

Hi Pierluigi
The one piece sprocket design that we used on our original Panther G was replaced with a two piece design on the Jagdpanther production two years ago. For the new universal hull design that we are about to produce, we have a new sprocket design. This has two pieces but does not have separate bolt on tooth rings. The detail of the bolt circle is corrected and the triangular cutouts are corrected.
To change the design further would increase cost and complexity, and I would be concerned about durability. The 1/6th scale design of these parts is always a compromise. An absolute scale replica would fail immediately in operation, because there would be insufficient running clearance and the fixing bolts would not be strong enough.
