This is another tip I have used for many years and it has saved me alot of time attempting to make a round item using sheet plastic. Some may be aware of this trick, but thought it might come in handy for some. Get you some round tubing, whatever size or thickness you might need. Using some evergreen or plasticstruct tubing which ever you prefer. I like to use evergreen. You can also use metal tubing if you use super glue instead of liquid glue. I use Tenax 7 or Ambroid Pro Weld.
* Cut out a small square piece of sheet plastic slightly larger then the round tubing your using.
Place the square piece of plastic on the end of round tubing and using liquid glue, it to the tubing (Not Alot)
I use a small piece of wire or old model car axle and drop, a small drop letting it flow into seam.
Let it dry for a while and then trim around square piece of plastic close as possible (Photo 3)
Using one of your small sanding blocks start sanding (Photo 4) UP & Down rotating the round tubing slowly, it will start taking a circular shape. After your satisfied with shape trim it off tubing and sanding the glue marks from glued side your done. Good Luck!
