packing

Before the packing can be fitted the perf pipe had to be cut to the exact length. Not too long that the end can can't be pushed home not to short that pipe is insecure, about 2mm of end float.

Next job was to wrap the pipe with stainless steel wool, this will prevent the fibre glass from being blown out. Once thats's in place the top quality fibre glass wadding was wrapped (£25) enough to fill the can.
