Committed to putting the tail piece into rubber so I can cast off fiberglass copies... it was going so well until I realised I was a glass short of enough silicone to finish the pour....
Expensive mistake both in time and money.
Shit happens although I'm a believer that proper planning helps avoid the shit, that said I'm too impatient to plan properly!
So measure twice and cut once! I'll do that next time. 😉
