Not sure if you solved this dilemma or not...
Bending acrylic panels, (large that is) is something I tend to steer clear of, mainly because it's more of a hassle / time consuming...
I've got uneven bends, burn marks, warping, etc
What I've done in the past if I needed to (for example) make a 90 degree angle with a fairly large piece of acrylic, I cut 1 side at a 45 degree angle. I prefer a scroll saw which has table tilt function, but a jig saw can be used as well, also with a tilt function. - This cut will be the start of the "bend."
I than take another piece of acrylic you can use the opposite side you just cut, but spare roughly an inch or two, because you don't want to crack the sheet (cutting so close to an edge). cut another 45 (2nd portion of the "bend". - I almost forgot keep in mind by sparing the extra inch or two, you will also have to equate the extra amount needed for "bend" i.e. when you bend say @ 90 degrees you need to calculate the "bend radius" which is a fancy way of saying the distance (point A) of the bend to (point b) of the bend, this in turn gives you an offset amount to your overall length needed.
If the above didn't make any sense here is a link to bending acrylic tubing which explains the bend radius in more detail from our very own B Neg! Here
Anyways Moving on...
Now you have 2 pieces with 45 degree angles, use some clear quick drying glue, spread it evenly as possible across one of the panels (just one) you won't need much, press the two panels together making a 90 degree angle, and let it dry. I normally have my wife put the vice grips on as I'm holding.
now to achieve a "seemless bend" by joining two pieces like I just described, heat up the joint, not too much but to the point where the lattice structures' of the two panels intertwine with each other. essentially your creating a "weld" with acrylic. - not to bend the panels just heating it to the point where it starts to look glossy.
Next let it cool down, and start sanding down the edge, sand as normal use a fairly rough grit, (I normally start @ 100 dry) and increment up to 1000 dry.
the sanding part is time consuming to an extent (depending on the length of course) but the goal is "grind" the edge off.
As you start to sand you'll start to notice the crease disappearing, before I polish I give a good wet sanding job on it, just to ensure a "seemless bend"
Polish the edge and you now have a seemless bend.
The guide I have used in the past is Here
Hope this helps
