Brief Description: Install fiberfrax and 1/16” stainless steel to fir
The night stared with me doing a little clean up and then got out the stainless sheeting and the cardboard template. Because the flange for the screw less cowling was made and installed the cardboard temp was to big so I cut it down and it did not fit right so I did what every other builder did was make a template out of paper and this work very well marking the holes and ducts with just a push on the paper. The template was traced out and the stainless was cut to the new size with a 1/16 “cut disc on my angle grinder. I drilled the holes with a 3/16 bit and enlarged with a steel bit from my dermal collection. Once I was happy with the fit the fiberfrex was placed and the stainless was riveted onto the firewall.
