Step 6: Heat Transfer Rod - Sealing it air tight

PAY ATTENTION! THIS IS THE MOST IMPORTANT STEP!! GO THROUGH THE PICTURE SERIES TO GET A GOOD IDEA OF WHAT IM DOING!

You don't want to mess this step up or it will get real messy. When I built the first one, I was having trouble creating a perfect seal and this area was the main problem. I have tried many methods to plug up the holes and this was the best solution I came up with. I just tested it and it works perfectly. If you have a better method of sealing, by all means go right ahead. 

1. Push the brass rod all the way through until you reach the inner wall of the next hole as shown in picture 2
2. Get you Seal-All ready and place it on the Brass threads and the hole on the other side shown in pictures 6 and 7.
3. Once that is done, grab the brass rod in the middle and turn it as if you are screwing it in shown in picture 8. This will spread the Seal-All adhesive all around the the holes which will hopefully fill in most of the gaps between the threads 
4. Screw until you cannot seal the threads inside the pipe shown pictures 9,10 and 11.
5. Take the two 1/2" Pipe Reducing Coupling and screw them to both ends real tight. Use a wrench if you need to. Again, make sure the threads aren't visible in the inside.
6. Smear Seal-All all around the couplings
7. For best results, let it dry for 24 hours. It should be hard and rubbery after a day and It will become rock solid when completely dry.
