As many of you know, i like experimenting with adding silicone coatings thin enough to fabrics that the fabric retains some air permeability. But my previous method of doing so is a bit of a PITA, and i don’t really get the fabric stretched out sufficiently enough.
So i’m looking to create a simple and cheap way of doing so. So far the idea is, get two wood boards for each end that are approx. 60 inches long (about the fabric width of most fabrics), drill some holes through both pieces (about every foot or so), put some gorilla tape on the ends of the boards that the fabric will be sandwiched in (for extra friction and to protect the fabric).
Clamp the boards tight with clamps, weave some rope in the holes on each end of the set of boards, tie one to a tree.
Here is where i’m a bit stumped, i want to be able to pull the fabric very taut and stretched. Is there some kind of inexpensive hand crank winch, pulley, or some similar device i could thread the rope through on one end to able to get it this tight, rather than trying to muscle it around a tree?
