I started to bend the sides, and to my surprise it's as easy as IRW.
I think it's probably because I thin the sides to teh correct thickness: 1.8mm at the waist and 2 at the rest.
The bending proceeded smoothly without any cracks.
The main thing to note is to allow the sides to absorb the heat before attempt to bend it.
The 2 wooden blocks which I use are very useful in supporting the bend and also to insulate the heat from my hand.
I didn't wear any gloves actually though it's a good practice to wear for protection.
And fortunately no burns this time round :)
After bending, I clamped the sides to the molds and leave it to settle in.
After the sides are in the mold, I saw off the excess ends.
