Impress Bead Liner - Centering pegs: Removing and Installing

Changing centering pegs and / or flaring dies.

NOTE:
To avoid misalignment, do not remove the anvil (ie, the bottom post) from the base. Pegs should be changed from the top, by removing the cone, or, if you prefer, by removing the base.

By Removing the Base:

What you'll need:
  • #2 Philips screwdriver (1/4 inch shaft.) Don't try to use a smaller screwdriver. It will damage the slots of the peg
Before removing the base, notice one leg of the Impress has a number in the casting. Mark the end of the base that is on that side, so you can put it back the same way it was.

Now remove the two large flat-head screws from the bottom which attach the legs to the base. once it is off, you can easily access the centering peg. Change the peg by unscrewing it from the bottom post. Take care not to twist the post, which might loosen it. Hold it with a pair of pliers if necessary. Do not over-tighten the centering peg. Just use one finger and thumb on the screwdriver. The bottom post is hardened tool steel and will cut into the softer screw threads quite easily, damaging the peg and making subsequent removal difficult.

After changing the peg, re-assemble the base onto the Impress body. Screw one screw in almost all the way, but leave it loose enough so the other screw can self-center as the tapered head aligns with the hole in the base. Gently tighten the second screw, and then go back and gently tighten the first one. Now tighten both equally. This ensures correct alignment of the base assembly and upper body.

By Removing the cone:

What you'll need:
  • #2 Philips screwdriver (1/4 inch shaft.) Don't try to use a smaller screwdriver. It will damage the slots of the peg.
  • A small bowl or container.
  • A 1/4 X 20 nut, old bead, short tube, or something similar in size that fits over the centering peg.
There is a single ball bearing inside the cone. Be prepared to hold the cone upright to avoid losing it.

With the tool upright on a table, grasp the cone lightly. Turn the handle counter-clockwise, until the cone is at the top of its travel. Continue unscrewing the screw untill the cone slides off the shaft. The ball bearing will either be inside the cone, or stuck to the end of the shaft by grease. Capture the bearing in the cone, and set them both aside in the dish.

Unscrew the shaft completely from the tool and set it aside.

Insert the #2 Philips screwdriver into the peg, and unscrew it by turning counter-clockwise. Insert the new peg and screw it in by hand. Tighten it GENTLY using ONLY your thumb and one finger on the handle of the screwdriver. Over-tightening will damage the peg.

Place the nut, bead, or whatever you chose over the centering peg. Screw the shaft back into the tool until the end of the shaft is visible by about a half inch or so. Place the cone with the ball inside it, onto the bead or nut. Screw the shaft down, guiding it into the cone until the spring clip contacts the cone, keeping it straight. Continue tightening the handle until the cone is fully seated on the shaft, good and snug.

Back off the handle and remove the bead or nut. The tool is now ready to use.
