It looks like the four sheet metal screws are to fasten the over lapping ends of the strip together to form the ring. The outer edge of the join is just to the right of the screws.

A sheet metal fabricator or an HVAC company would be a great source, They will have a large shear to cut it cleanly to size,

Sheet metal shop.

Screws secure the overlaping ends of the sheet metal band?

Perfect. Thanks guys. I was worried about having to get exactly the right size metal piece and this gives lots of room to adjust it to final dimension. Big help and is much more doable for me now.

Often you can find thin sheet metal at the big box stores (Home Despot, Lowe's, Menard's, etc.). It is easy to cut with tin snips, but wear gloves and be careful of the edges. You'll get a cleaner edge using a metal bandsaw if available. Of course, you'll need to seal the edges anyway with silicone and/or some kind of trim piece inside or out. Depending on how you handle this, a slightly rough tin snipped edge may not matter. Also, you could use sheet acrylic as an alternative, but might need a frame behind it for structural support.

If you can use aluminum you can get a roll of aluminum flashing in a variety of widths like 10",12", 14", and bigger.

Ed, that sounds like a great idea. I wonder - do you think the flashing will be rigid enough to support the wooden donut and canister?

thanks,

Depends on the gauge. You might need some vertical stiffeners inside or outside of the new cylinder. I think you can tell by the feel the stuff that is too thin to bother with.

Thanks Ed, that makes sense to me. Thanks,

It was mentioned in another thread, and seems like a good idea, that threaded rod with nuts and washers would make good structural components for this if needed. This should eliminate any concerns regarding the strength of the sheet metal.

Finally got it done. Ended up using 24 gauge sheet metal that a local HVAC shop cut for me. Wow. What a difference this new filter made. I think it's much quieter too. Also made the DIY manometer so I'd know when it needed cleaning. https://www.youtube.com/watch?v=a9l9e8P ... =emb_logo Took lots of gorilla tape to get a plastic bag completely sealed over the filter to simulate a clogged filter in order to show the reading when completely clogged. Now back to some wood turning.
