Mounting Board for this Round Printing

Continuing on the task in the earlier post, I've found a spare 4 x 4 ft foam PVC plastics board of suitable 10-mm thickness. With my portable jigsaw, I carefully sawed the circular profile with a diam slightly smaller than that of the printing. A central pivot hole is then drilled.

This round board is sufficiently stiff, and not too heavy. It's round shape makes it sligly awkward for one person to move it around. But fingers can be slipped into the central pivot hole to help with this task.

I then got a short pvc pipe for the central pivot and mounted it on my wooden A-shapes floor stand.

The arrangement shown below in my workshop is now ready for the gluing operation.



For this gluing, I plan to use spray adhesive. But I need to buy a new can as what I have now is a bit old and not working well.

But then, one thing bothers me. The circular edge needs to be framed to avoid the edge spaying. Frame materials in frame shops are all straight. This frame material has to be flexible to make it follow the circular profile. A split rubber hose is not the best frame, but there seems to be no other choice.
