That’s a tough theme. But we finally landed on the obvious. I scaled the original can to get the ratio of diameter to height. I measured the skin, tagboard from shipments of panel stock, and from the 47.75 width ended up with 64 inch height. I made router-cut round bulkheads, joined by staves pocket screwed where it wasn’t possible to staple the ends. For obscure (to me) reasons I divided the circle in fifths. I guess if 72 degrees makes a room comfortable, it’s reason enough to use the same number to make an aerosol can replica. (Next time I’d use full length staves and notch the intermediate bulkheads while the ply was still square. It would be much easier than the way I did it, and four staves instead of five would not be a negative.)
The skin is glued and stapled.
The center holes of the bulkheads were 1/4”. I remembered to overbore the end and penultimate bulkheads so I could thread a 5/16 shaft in there to support the tube for painting. I literally held the paint roller on the surface and spun the tube with my other hand.
Linda cadged the Pledge logo off the web and printed it to scale in two pieces which we wed and then stuck to the tube with 3M 77. The pledge itself was added in graffiti-like Sharpie, again by Linda.
The last image shows a base I had built previously to display basses. It already rotated on a nice bearing, but was driven by a 110v motor. I removed that and installed a DeWalt 12v LiOn screwgun with a bolt, through a teenut, to control the trigger. Actual on and off was accomplished by inserting or removing the battery.
The rotation was very nice, making the text easily readable. It lasted easily through the parade.
Here is a link to a brief edit of the event, shot from a downtown building roof by Dan the Man. We appear about 1:40 in. Linda is the tag along clown, dusting anything she can find to dust. The three precision marchers are Lily, Maya and Bjorn. Juni chose to ride the racecar. T’was a grand day for both grandparents and their grandchildren.
