Replying to Sizing in a regular down-flat-down rail.
so, we are building some rails at my school, and i'm worried about making the DFD too long, if the flat gets to long it will be hard to place it somewhere. i'm thinking 1,5m. that would be like 4.9' ?
or could someone give me some idea of what this rail is like ? https://newschoolers.com/web/content/viewvideo/id/291380/cat/top/ on 1.50 when henrik does he's thing.
and what in what angle should it be ?
