What is the application?
If the inside doesn’t need to be a smooth circle, birds mouth joints would work well.

The height is a bit of a challenge, but for something like that the first thing I think of is rings of glued up trapezoids (probably 8 per ring). Each ring is glued to another, offset by 1/2 segment for strength. A router with a circle template would get the inside (and outside if needed) perfectly round to a precise dimension. I’d probably do the routing on two-layer (1-1/2” for 3/4” stock) to keep within the capacity of a typical bit. Basically this is how segmented vase turnings start out.

It is going to be the duct for a 15 inch propeller that is part of a wind tunnel, an EDF, Electric Eucted Fan.

How smooth does the inside need to be? Do you have access to a lathe?

Since I do have access to a lathe, I would simply cut staves 5” tall, and glue them into a ring/short column. I would go with 12 staves to keep the angle easy to cut and to keep gluing easy. Each stave is cut at 15° (360°/12/2).

With a lathe, it’s a simple matter to round the inside and outside. Without a lathe, you would have to decide if the flats would cause airflow issues.

You are basically making a drum shell. My first thought was make a round form and coil a sheet of veneer several layers thick, or however many layers you feel is necessary.

I’d think about a thin clear plastic sheet. Clear plastic because you can overlap ends together and weld right through the sheets with UV activated plastic, like Bondic. As Mike suggests you could wrap and weld additional layers for greater rigidity.

I have used it in my shop for small plastic repairs with good results. Available at ACE Hardware.

Bead and Cove router bits. First run the long strakes than cut to length. Glue up. Piece of cake.

These images show some possibilities:

Right now I am leaning towards the veneer wrap but the plastic wrap looks intriguing too!

You could check instructables, I used that website a lot whenever I was in a fix.

Have your say...
