Tools of the trade for the canopy trim work are shown below. I clamped some wood at 44 inches apart to hold the canopy while I cut on it. Clamped the wood with whatever clamps I could find that worked. Vibrating (oscillating) cutter saw from Harbor Freight worked very nicely with some exception. A hack saw blade that I ground a ''rounded V'' into was just the bomb for deburring the canopy edges which I cut with the vibrating saw. I also put some 60 grit sandpaper on a hand sander to remove a couple high spots and some melted-then-solidified canopy material in a couple spots along the saw kerf. I also had an infrared temperature measuring device which made me feel better knowing that the canopy was between 85 and 95 degrees while cutting. What I could have used to make the job a little easier was a 2nd set of hands to help get the canopy on/off the airplane. I managed ok by taking my time and handling the canopy slowly without stretching it while I put it on and took it off.
Some old wood clamps on the left and some deep C clamps on the right.
This little tool worked just fine. I will try the Vans supplied grinding wheel next.
This is the deburring tool I made from a hack saw blade. Works really well.
