Rudder Pedal Installation

I finished removing the glare shield today then proceeded to work on the rudder pedal installation. I dug out my phenolic blocks and then discovered I need to order the necessary bolts. Next, I proceeded to remove the powder coat from the bearing surfaces. I reviewed the EAA home builders video where John uses a propane torch to heat up the paint and a wire brush to remove it. I tried masking the edges of the area but found this to be less than satisfactory. The tape only burns and turns into a gooey mess.
