I am debating how to fix 4" dust gate inside 4" metal pipe. It is a some play for my taste ( about 2-3 mm). I can put a few rounds of tape, or will use some waterproofing material from HD or
How to keep agates in place?
And can I drill a holes thru the pipe and gate side and screw it? What to use - metal screw?, bolts?
Thank you, Ed.
