VinnieFthere's several tons of assorted metal, scrap and otherwise, to find what I need for legs/feet. shouldn't be a problem at all.
word word. Just wanted to make sure you weren't planning more rails than you had steel for.
IMO, 24' s kind of short for a dfd. Anything under 10' on the downs is tight and you're looking at 9' or 10' at the longest that way. Flat bar is def legit, a feature you need. Same with the 16' FD. Kind of short imo.
I would thinking about scrapping one of them to make the other a bit longer. Or if you have any similar steel in smaller lengths. Maybe something long enough for your DFD flat.
That said it depends who's going to be using them. And that's just my thoughts. I tend to go long and mellow, and everyone's different.
