This is great. I was planning one out last week and was curious what materials to use to paste this into the tubing. Thanks for the instructable and education on furnace cement. Good find! This type of quick and easy gives confidence to just think and DO.

It Would be nice if you'd put little more write up here. I'm not a paying instructable and am going blind - glasses won't help. I mean to say the tiny little pictures on instructable are readable but, not enjoyable.
