Default Custom fitting

So as mentioned in my tonneau cover thread, the existing fitting is slightly too high and rubs on the aluminum.

I picked up another 2” NPT hex plug, steel, to start as a base for this.

Today I fired up the welder, and built up a rough rectangular area on top of the plug.

Next step is to get the mill going and start carving.

Find one of the brass low-profile street elbows. Should save you quite a bit of room. That standard steel el you have now is pretty tall...

I did hunt for one at the time, with no luck locally. This version will gain me another 3/4” or so even over the low profile fitting.

First pic is after the first round of welding.

Next is after a bit of time on the mill today.

Bit of tidy up to deburr it, clean it and squirt a bit of paint and I’ll call it ready to install over the next day or two.

Nice! Did you have any trouble machining it, it looks quite hard.

Nope, pretty much machined same as mild steel. Even drilling the side hole which would be half original, half weld metal, other than chips breaking a little easier, it cut no issue.

Nice. I never thought of doing that.
