Tidied Up Firewall Forward Wiring

I got an order from McMaster Carr that included some more silicone adel clamps along with some tefzel zip-ties.  I installed a few to secure all of the wires near the right firewall pass-through.



This nicely tidied up the EGT, CHT, and Lightspeed Ignition wires running across the upper engine mount tube.



I also replaced a bunch of the temporary nylon zip-ties with the tefzel.  Regular nylon zip-ties are only good up to about 185º F.  Black, UV stabilized zip-ties are better at up to 221º F, but tefzel is good up to 300º F.  There are even higher rated zip-ties such as PEEK which is good to 500º F, but they're over $3 per zip-tie!  All of the wire insulation in the plane is also tefzel insulated, so if it's hot enough that these zip-ties melt, I'll have other problems.



I also finished up the Dynon GPS mounting bracket.  I put a gentle radius in the lower flange to follow the curve of the engine mount and drilled a few lightening holes.  I then primed and painted it gloss white.
