Lots easier than you might think, especially for a thin project like yours.
Use a piece of plastic plumbing pipe, (PVC or CPVC), of the appropriate length and diameter for the project. Set it up with a little pitch to drain the condensate out, and appropriate bridging to elevate the workpiece above the trickle of condensate. Seal one end with a glue-on fitting. On the other end, make preparations for the stock to be steamed by preparing a tube to introduce the steam from a standard teapot. Seal that end losely with a rag.
After the piece has been steamed for the required length of time, remove it, (Hot!), and apply it to the bending form immediately, with quick clamping action. I would suggest experimenting with short sections to determine steam times and workability timing.
Hi, BOB!
re: steambending info - THANKS!
too late for this project, but will/may prove useful for others.
