Brush seal recommendations
Obviously, I need something that can be bent into an arc, so aluminum retainer strips are out. I see some options for flexible brush only, no retainer, but how do you attach them?
And the cost! With the products I have seen, it looks like it is going to cost me about US$500 before shipping to do the 25+ feet of circumference.
I am sure others have done this. How did you do it?

Re: Brush seal recommendations
With my new-to-me acquisition I have noticed an airflow issue between the top and bottom. While your structure is different than mine I too am considering remediation, 'cause I just know I'll have a snowbank in there if I do nothing!!!!!
I am considering a appropriate skirt mounted to the outside diameter of the dome, but not firm on a plan!
While not color matching the material I'd considered is Round hay baler belting. It is pricey, but no where near 500 USD, and readily available.
Subscribed now to see the responses.

Dust, breeze, snow, insects. Even mice and rain.

Re: Brush seal recommendations
Mice are crafty, and can cause a lot of damage. The Atlantic mice sound like they have a skill Saskatchewan mice don't have. The ability to scale a vertical plastic wall wall is one tough act to follow. A brush won't keep the little buggers out, more like nesting material for 'em. IF they can get their nose in, THEY can get in....
Geographic location plays a major roll in keeping the environment out of a building. Here wind driven rain and snow pose serious issues, especially for pricey electronics.

Re: Brush seal recommendations
It's a hard area to photograph. Here are a photo and a diagram. The photo is my dome. The diagram is stolen from someone else who did a similar mod to what I have in mind. The brush seal would be attached to the outside of the rotating ring, so that it brushes against the support ring.
That would be flexible radially, so it would be possible to install it. Unfortunately, it wouldn't flex at all tangentially, so it would add a lot of friction to dome rotation.

Re: Brush seal recommendations
I don't know what happened the first time. I have re-uploaded the images.

Re: Brush seal recommendations
I have had a lot of "catch on the re-work" issues thrown at me in life, a image is a great starting point, however, the task always seem to take a twist once you get eyes and hands on it in person. ROFL I've never been to Hall's Harbour. But it would be a trip......
