Demi Duster Electric - part 2 - the CAD learning curve

First bits in CAD drawings are done. There are so many commands in ModelCAD, and I wish I knew how to use some of them. But, I just struggle along and it seems to get the job done (at least so far).

Now, as if ModelCAD doesn't keep me busy enough, I've begun to think that this plane would look much better with a plastic canopy, rather than the 'simulated' canopy made up of balsa sheeting. I've been checking YouTube videos on how to build a vacuum form table at home. Honey, why don't you go shopping, while I just warm up the oven?

Heat shrinking a PET drink bottle is easier than vacuum forming for limited production.

Haven't heard of that. Can you give more details, or a link to a "how to"?

Thanks! Looks easy enough. Best part is, the 'canopy' on the Demi Duster is all flat surfaces, so there won't be a lot of carving needed for the form.

Oh, what the heck. I had enough stock around the workshop that I decided to build a vacuum table anyway. Cost = $0.00
