Got onr done. I'll let the caulk dry and then better support the duct. Then move onto the second one.
I tried to taper the inside of a 4" hose fitting to fit over the DC fitting on the table saw. I found out two things. First, I need to learn how to turn. I completely destroyed the hose fitting I was working on. You guys make it look so easy.. lol
Secondly, when I was making a jamb chuck for the fitting I used my chop saw. As I said I use to run both chop saw and table saw without DC and then just clean up the mess at the end. This time I hooked up my shop vac to the chop saw, but dust flew everywhere. either the connection (it was clear of debris) doesn't work or I need a bigger shop vac.. lol
