Sheet Metal Tool Modification: Look for: WISS Hand Seamer (as LAST resort BRAMEC or VISE-GRIP) sheet metal bending tools and modify as shown. Recommended for QUICK, tight crimping!
|1. I prefer the Wiss Hand Seamer Model HS-1 (3.25″) or as a LAST resort you can purchase Vise-Grip Locking Sheet Metal Tool #23 (3″) or Bramec sheet metal tool-straight handle (3″ seamer comes in 6″).|
|2. So the tool tip will fit into the troughs to crimp the crests: bevel up 1/4″, knife edge, by grinding the length of the tool face and back plates. Vise-Grips: If there is a gap between the faceplates, adjust the center slightly with a hammer. Or tighten the locking screw, release the handle then turn the locking screw a quarter turn.|
|3. Place the tips of the tool into the troughs and crimp! It takes patience and practice with hand placement, gripping and releasing to get the rhythm. You can do it!!|
