Aw, BRI... I'm so sorry to hear of your loss. It's always tough when you lose a loved one. It's not at all fair the way your father's acting in this, not letting you go to the funeral. What the hell's his dysfunction? Geez.
Since you have all this free time what with not being on talking terms with your family at the moment, I agree the best thing to do is to keep yourself busy with work and projects like this. Helps to keep your mind off things a bit. I would know.
Though it's taken some time for me to get back to this thread (had some things going on recently that kinda preoccupied my time for the most part, and kept me away from here), I'm glad I decided to stop by today and see what progress you've made.
That SR is looking pretty damn kewl there. You've obviously got most of it together, minus the PVC barrel. I can already imagine what it'll look like finished, heh. Everything looks good to me, so I can't really think of any constructive criticisms to post.
One thing for when you're bondo-ing, though. Make sure to do it in light, thin layers. You don't want to apply too much as that could obscure any details present on the Pep model, and will result in unnecessary work on your end to sand it down and thin it out.
Unevenly applied bondo can also lead to unbalanced weight throughout the piece, so be careful of that as well.
Btw, what did you decide on for installing in the scope housing?
