Ran into a guy that used to have his weld shop a few bays down from my shop and asked him to weld up a few of these cool little.....er..uh...thing a ma bobs. He's an ex Boeing welder and welds Stainless for a liveing. These were made from stainless fender washers from the hardeware store and some stainless tube he had at his shop.

The nice thing about haveing them made for me is I can specify the angle that the tube sits at. I'm haveing one more made at 35*. Installation is not quite finished in the picture above. Just needs one more clamp.

Looks great, especially the slanted pass-through, but I gotta ask, whats the gold color wires?

Those look like thermocouple wires to me.

Looks a lot like the ones I bought from the nice people at Safeair-1.

I never said it was an original idea. I looked at the ones Safeair made a couple of years ago and was blown away by the price they were chargeing. For those three it cost me $30.00 the 35* tube is going to cost a bit more. Yes those are my EGT & CHT wires in the picture.
