Excellent job! What did you use to cut out the parts?

I changed your video from a link to an embedded video so that people can watch it from within the site (using the insert/edit embedded media button). Did you make this from plans?

Wow, how did you get such clean cuts with a cutting torch? The few times I've used a torch my parts came out melted along the edges and looked terrible. Yours look like you cut them out with a cnc plasma cutter! You must have crazy skills my friend (or I have none, that's probably more like it)

As far as the 2k members go, I think a lot of them sign up so that they can download plans, but aren't necessarily interested in participating in the forum. But I had to make the plans a members-only option because I had a lot of bots downloading thousands of copies a week, which took up a lot of bandwidth (which is expensive for me from a hosting standpoint), and made the site run slow. Don't ask me why someone would create a bot program to download PDF files, it doesn't make sense to me. 

I also have the site setup so that I members don't get a lot of annoying emails. If I had a daily or weekly digest that automatically told members that there were new posts I think a lot more people would participate in the forum. It's a fine line I'm walking – trying to make the site a resource without being a spammy nuisance. But I may have to make some changes eventually so that people know when there are new posts. 

We do have several active members though, including you now! So thanks for that, your contributions to the forum really are appreciated.
