I wanted to take a break from the base, so I moved on to the boiler, it's worth cutting and folding one of the end caps first to make sure you glue up the boiler body to the correct diameter, my kit enlargement required me to overlap my glue joint nearly 2mm(extra) to get a tube that accurately match my end caps. The more you pre form your boiler tube, the better the outcome will be.
In the photo I have just wet out the glue flap with a rolling pin, but you can use a wood dowel, you are trying to avoid the glue flap being a flat spot on your tube.
