63mm (2.5") to 50mm pipe adapter

Connects a 2.5" (63.5mm) hose to a standard EU 50mm pipe. 

A hose clamp or a strip is a good idea. The adapter tapers a little for an easier fit. 

Allows you to connect those pesky 2.5" hoses from dust collection kits, to your 50mm pipe system ;)

Let me know if it works for you or if I should tweak something.
