For those that sometimes shoot older recurves off the shelf...
How have you created a crown on a completely flat shelf? I've seen the feather rest and have used the Bear Weather rest, but am still curious as to other ways archers have approached this.

On some bows, mostly Bear bows with some collector value, I've carved a piece of scrap harness leather into a crown, and glued it down on the shelf with Barge cement. You just need a small peak, and you don't need to raise the arrow a lot higher over your hand.

On other bows, Pearson and Shakespeare without much value other than as shooters, I've used a wood rasp and completely reworked the shelf, lowering it and making a nice peak. I keep the peak of the peak (!?!) right over the deepest part of the grip. If you decide to take the rasp to your bow, remember to keep a bit of radius (about 1/16" min) in the corner where the shelf meets the sight window. A sharp corner is weak and can cause the bow to break.

A simple match stick left slightly larger then a normal 'pressure point' stick, glued with barge, and some velcro over the top.

Place the stick inline with the throat of your grip (deepest part)
