TOOTH BENDING OR UNEVEN SWAGING

SET SWAGE UP ACCORDING INSTRUCTIONS FOR INITIAL SET-UP, HAND or AIR

CHECK SHARPENER ALIGNMENT

Refer the Band Saw Troubleshooting Guide to ensure proper set-up of the sharpener.

  1. Check feed finger and face plate alignment/wear.
  2. Make sure the saw isn't sitting too high in the filing clamp or sharpener gate.

NOTE: About 1/2 of all tooth bending/uneven swaging problems result from grinding off-center or out-of-square.

 

CHECK ANVIL

  1. Make sure the anvil is absolutely square. (Anvils should be reground only at the Armstrong factory.)
  2. Set the anvil to the right height with the correct anvil setting gauge. The number of the gauge and die should match.
  3. Check for wear. Replace the anvil if wear exceeds .001"- about the smallest amount you can "feel,"
  4. Check the position of the anvil to the saw tooth. Adjust the anvil to be flat on the back of the tooth by rotating the swage head forward or backward.
  5. Anvils ground with back clearance cannot be set with anvil setting gauge. (See section on high back teeth.)

 

CHECK CLAMP SCREWS

  1. If the clamp screws are worn and have dull ends, it's time to replace BOTH of them.
  2. The gripping ability of the tool could be hindered if the center ring is too high.
  3. If the head is getting "sloppy", check for worn threads.
  4. Keep the threads on the screws and in the head clean.
  5. Are you able to cut a "donut"? Check the clamp screws by sliding a piece of paper between them and applying light pressure. You should be able to cut a perfect donut shape. Be careful not to clamp too tightly, or you could damage the clamp screws.
  6. Saw gauges 20 or lighter, should use smooth end clamp screws. (Available for No. 2 Armstrong swages or smaller. Part Numbers: 6234 and 1424.)
  7. Check for signs of slippage on the saw. Watch clamp screw marks. If there is blurring, it could be time for new clamp screws.
  8. NOTE: Slippage can occur from pitch build up in clamp screws. Pitch packed in the stationary clamp screw causes the tooth to bend toward the moveable clamp screw side. (Reverse is true of pitch in moveable clamp screw.)

  9. USE CARBIDE TIPPED CLAMP SCREWS! They grip much better than steel.
  10. Apply even clamping pressure.

 

CHECK ECCENTRIC DlE

  1. If it is worn-out, replace it. If just one area on the die is worn, move it over to a "fresh" spot (at least 1/4" or 6mm).
  2. Too much bite? Reset the back stop to reduce bite.
  3. Is your die too big? Too small? Maybe you need a different swage size. See the Swage and Shaper Selector Chart.
  4. Use the appropriate "style" or "bite" of die for your application. (See Die Selection Chart.)
  5. Is the die hole in the head worn?
  6. QUICK CHECK: is chamfer around the die hole a uniform width. Worn swage heads will have less chamfer 180 degrees from the anvil.

  7. Check for wear in the die "lock" or stop bracket. The die should be held firmly and not allowed to "slide" inside the head.

 

CHECK SAW

  1. Make sure the saw teeth are not bent before swaging.
  2. Check to see if the saw was ground off-center (face or back).
  3. Is the guide arm of the swage in line with the swage head? Check by lightly clamping a straight edge with the clamp screws. The straight edge should center between the "ears" at the front of the guide arm. Bend the guide arm as necessary until the straight edge centers when clamped with new clamp screws.
  4. Are you swaging beyond the end of the filing clamp? Swaging a "flexed" or unclamped saw will cause tooth bending or uneven swaging.

 

CHECK SHAPER

  1. Shaper jaws should be aligned, parallel and the ends should be flush.
  2. Shaper jaws should always be a matched pair and should be correctly ground.
  3. Be sure the saw is properly aligned down the center of the shaper.
