Finished Pockets, JB Welded Gas Pipes to Flanges

Today I gave the pockets for the under shoulder details one last sanding and coat of primer.

I think this will have to do for now, it's time to move on.

Next up, preparing to JB Weld the pipes to their flanges.

Note that the inner pipe is pre-threaded gas pipe, while the outer pipe is electrical pipe that Home Depot and Lowe's will thread for free in the store. The electrical pipe accommodates the gas pipe much more easily than a gas pipe/gas pipe combination, due to a welded bead running the length of the pipe on the inside.

The first step is to thoroughly clean the threads on both the pipes and the flanges with acetone.

Several paper towels and one dissolved rubber glove later, and they are clean.

Next, applying JB Weld to the thread on the pipes.

The flange is in a vise to tighten it down, the vise is protected from oozing JB Weld with a paper towel. I hand-tightened first.

Then I used a pipe wrench to tighten the pipe as much as possible into the flange.

I plan to insert four steel pins through of the pairs of flanges and pipes, to further lock them together. Having these unscrew while driving would be a bad thing.
