Additions:
Work in steps, applying hot glue into the channel first and putting in the purfling as quickly as possible, because in a manner of seconds, the channel starts to swell making it more difficult to insert the strip. If that happens, use the small hammer and a smoother to drive it home. Avoid putting glue on the purfling itself as it also swells in length.

Additions:
You bend the purfling material as you would the ribs, using the bending iron; only the temperature should be set lower, ie. 200 degrees Celsius, depending on what the glue in the purfling can take. You can moisten the strip slightly if it helps prevent cracking. Precaution must be taken not to overheat the strip because the glue binding the layers together then melts and swells causing them to separate. If possible, try the bending on scraps first.
~1) As mentioned earlier, for an easier fit, remove the edges on the bottom side of the purfling (using your scraper), making its cross section look more like the letter U. See **Fig. 1** in the previous chapter for reference.
~1) Run your finger to check that the purfling "sits" evenly along the whole outline. If not, you may need to remove some more wood here and there. When removing material from the corners, again, be very careful when cutting next to the inner corner tip.
If you`re working on the spruce top, you can now cut the top and bottom bout purflings in half (if you haven`t already) where the neck and the saddle will be later installed. This will make it easier for you to fit the tips of the corners right at the time of gluing. This doesn`t apply to the maple bottom plate purfling.
