Don't worry, you are doing a mighty fine job. Looking great so far! i like how clean the BRS screen top came out. Where did you get the supplies from?
I used the BRS kit from here. The 3 foot kit was $37. All bars needed to be cut to size, then endcaps fitted, then roll the spline into the groove and trim excess. I think it took about 30mins to complete. BRS has a video guide as well.
