Chainstay Dimpler 

• Tapered golf-club inspired "swoosher" shape provides just the right shape dimple.
• Non-marring thermoplastic.
• Sized for a snug fit on 1" ram on most 1-ton arbor presses.
• Brass threaded inserts for securing with M5 screws.

Other shapes and ram sizes in the works... please inquire.

Huge thanks to Fitz Cyclez @fitzcyclez1 for the action shots and prototyping help.
