Using pineapple racing 13bt templates. Just finished my secondaries today. Let me know if you see something that I did wrong. I think I need to polish the one on the left a little more.

 

They look pretty good. I would just add more radius on the closing edge.

 

yea i know I was thinking the same thing but since I was using a template I don't know now much further I can go without using one. I know that the mazdatrix template had more on the close edge but the left the opening side of the port untouched. While pineapple template had open and closing porting. I don't know if I want to spend the extra money to buy the mazdatrix template just have more radius on the closing edge. Unless there's a rule of them for porting without template.

 

i think you did a pretty good job, too.

as for adding better radii, it's a little tedious, but maybe you could use a degree wheel to help. another idea (much simpler) may be to get some plexiglas and make your own closing boundary and blend in the radii.
