Tool set N-21 for riveting
Tool set for riveting machine NM-11.
Used to remove/attach tube rivets and attach copper rivets.
Tools N-E are only included in N-21 when buying a new NM-11 skate riveter.
Remove tube rivets
Put tool number 1 into the hole of the hook 12 and fasten it using the nut that is included. Loosen the Allen screw in the tool holder 11 and fasten tool number 4 (hole is Ø8 mm). Position the skate above the hook 12 so that you can feel tool number 1 in the rivet. Lower the tool holder 11 so that the tool 4 fits around the head of the rivet. Press down and the rivet should come loose. It will not come completely free; remove it with a pair of tongs.
Attach tube rivets
Put tool number 2 into the hole of the hook 12 and fasten it with the nut that is included. Loosen the Allen screw in the tool holder 11 and fasten tool number 6. Put in the tube rivet with its head outside the skate. The rivet should then protrude about 5 mm on the inside. Position the skate above the hook 12 so that you can feel the tip of tool number 2 against the hole of the rivet. Lower the tool holder 11 so that tool number 6 reaches the rivet head. (Move the skate sideways and up and down. The rivet should be held in place by the tools.) Press firmly and the riveting is done.
Attach copper rivets
Loosen the Allen screw in the tool holder 11 and fasten tool number 5 (hole is Ø6 mm). Put tool number 3 into the hook 12. Put in the copper rivet with its head inside the shoe. Position the skate on the hook with the rivet head against tool number 3. Place the copper washer onto the copper rivet and press it all the way down to the plastic with tool number 5. Then shorten the rivet with cutting nippers (there should be about 2 mm extending from the washer). Again put the skate back into the machine and place the rod tool number 8 through the holes in tool holder 11 and tool number 5. Press down the washer firmly and use a hammer to hit the rod so that the rivet will get thicker than the hole in the washer.
