As long as the splice is at the same
temperature as the indicating device there will be little or no error
introduced by the splice. Bring the thermocouple wires out of the engine bay
before the first splice with non thermocouple wire and it will be good to go.

This may help..
EGT's are thermocouples.. they measure the temp at a junction of two
wires. Whenever you create a splice onto the thermocouple leads you
introduce another junction that can serve as a thermocouple. Best solution is
to have a single long lead that runs all the way to the device.. buy it that
way. After that.. trouble shoot grounds..

Way to go Chris !!..........I (years ago)
needed to learn to weld for my "Dyke Delta" project (which is
a weldors nightmare)...............The Delta was so
intimidating that I choose to build a "Cassutt" first
which is a much smaller welding job to hone my
welding skills...................I like you found Gas / Oxy
welding skills were relatively easy to pick up and
surprise "Enjoyable".......I have since also acquired
a "Lincoln"
175 tig and found this skill easy to pickup as it is similar
to Gas/Oxy with a different heat
On a different note did you notice what your EGT reading
was at 6450 rpm and 34.5 MAP ??..........

Well, yesterday actually. I completed
the EAA Sport Air workshop yesterday on Welding. While I know
the Gas Oxy method it just a BIT antiquated by all the new stuff, the
class removed much of the mystery involved. I was amazed at the progress
made in just two days. From dripped, blotchy beads, to "not all that
bad", somewhat consistent beads.
I know it is not much of a leap for many of y'all,
but I always felt quite lacking not having a base understanding of the process
(videos and books just do not breach the gap). Now I will be looking for
a Tig course, or even, now with a basic comprehension, even a friends
input. The Velocity is not a big welded craft, but there were a few
things I would at least have entertained, even if I would have farmed them
out anyway.
On the rotary front, since I dedicated a bus
for just the EM2/EC2 and reinstalled the units in the plane (currently
using Rino's old unit since the wiring is correct for it...my unit has a
pin difference being a later unit), I am currently NOT having my tach
dropping out at 6000 rpm (so far). Last night I did a quick run up after
leaving from the welding class and ran up to 6450 rmp static at about 34.5
MAP. I had trouble holding it with the brakes...and this was on rough
asphalt. I hope to get out there in a bit and do some tuning and
RE-determine best cranking settings. It is starting quickly when
cold at full rich mixture. Gotta keep it a full mixture for a few
minutes till it warms. However, it is taking quite a bit of fudging
around to get it to start hot. Per Mistral, my injectors are large so I
think I may need to go leaner (about 10 o' clock currently) when
hot...or so my preliminary feeling is such. For those who are not there
yet, you pretty much have to start over with base mapping every time you
get your units back from Tracy.
Of course, I am getting much better at it...... ;-)
