I started with the front and rear flaps. Amazingly, the canvas I have is 71 inches wide which is exactly what it measure out for the rough cut before sewing the bottom hems/edge or whatever they're called:
I recently retired, and I took my desk that I had for the past 27 years. I measured it up and then welded up some adjustable castors. Dialed it in to match my sewing table. It actually serves pretty well as a sewing table extension. The three main sections of the cover are 113 inches long. Lots of canvas to manage, so the desk is really coming in handy.
The rear flap has extra layers of canvas on each side. Likely due to it being used more often then the front flap I guess:
Little tricky getting the flaps to radius. The top bows on the Ben Hur rack are curved, so the canvas has to follow that curve. I used a wrought iron section and curved it to the radius of the original canvas cover:
Was feeling good about the project, but not so fast! The radius on the front and rear cover sections where the canvas flaps are attached was not too easy to do. Took me forever to get it decent. I'm sure sewers have some type of trick to make the curve/radius in the opposite direction. Not sure what that would be. The original looks pretty good, but not sure how they did it:
Actually pretty fun looking at how the original cover was constructed and trying to duplicate. A real mind bender for me to get all the measurements correct. Actually trying to make it a tad larger thinking that shrinkage may set in. Not sure if that's an issue or not.
