General - My Warp tension keeps coming loose?

The best way to see if the problem is the brake or your warping is to see if you can move the warp beam with your hands without stepping on the brake. If you can move the warp beam, then you need to add more tension to the actual brake.

If you can't move the warp beam, then you need to pull down on the paper more during warping or have someone or something (stack of books) put tension on the chain while warping.
