Hello all, this is my first post, although I’ve been reading posts here for a long time.
I’m working on a Thien top-hat for my new dust collection system, and would like to make part of the top baffle out of clear plastic so that I can watch the cyclonic action. I’ve searched all the normal online supply places and I can’t seem to find anything suitably thick (0.125 1/8th thick at least) yet flexible and see thru such than I could make a circular band about the size and shape of the lower 1/2 of a Home Depot bucket.
Where do you get your acrylic/pet/whatever type of plastic for these types of application?

I would look for 1/16” polycarbonate (lexan).
It wont break and will be flexible enough to do what you want.
I have local plastic shops here that carry it.
google plastic suppliers, or acrylic sheet goods and you should be able to find some.

Math – go by a local upholstery shop in your area – or even a boat canvas shop.
they use thick clear plastic for several applications.
just last week I saw some in Wal-Mart in the material/sewing section that is
used for storm window coverings. it is not hard to find if you know where to look.
problem is – not many adhesives will stick to it – so you will to experiment on that part.
even some automotive upholstery shops use it for the rear windows in convertible tops.
it is not as thick or stiff as plexiglass and lexan.

BORG carries some sheets of thin acrylic. Mine stocks 1/8, 3/16 and 0.220 inch product that used to be called 1/4 inch?

If I need thicker, or larger pieces than BORG can support, my local glass repair shop has a huge assortment of acrylic on hand from 1/16 to 2 inch thick. They also stock many sizes of unbreakable poly-carbonate used for bullet proof windows.
Another potential source for sheet acrylic I have used in past is custom aquarium build shop, or commercial sign maker. Both use clear and colored acrylic in their products and might have spare stock on hand they would be willing to sell.

That said, you can buy pretty much any plastic known to man kind from US Plastics, it you can afford it. Shipping cost on large pieces is horrible, and it is usually best to find it local.

At my local BORG the lexan, acrylic, and photo glass are in a small section hidden against the back wall. Pretty tough to find. Search on the website, filter by your store, and it will tell you what isle/section it is in. Sometimes there’s even a store map.

A small window would probably suffice, or a series of smaller windows. It would probably be pretty tough to get one piece to wrap all the way around

Thank you everyone! I was able to order some 1/16 lexan online from Amazon that sounds promising. I just needed to know what terms to search for. I’ll be sure to post my project in the coming weeks.

I used 3/32 PETG from McMaster Carr. ClearVue cyclones use PETG. Best balance of flexibility and impact resistance? Anyway, it worked for me. Here’s a link it.
