Connector Materials:

(2) 3/4" diameter sweat fitting to 1/2" threaded male copper plumbing fitting

(2) 3/4" diameter sweat fitting to 1/2" threaded female copper plumbing fitting



The outer diameter of the 3/4" sweat fitting matches the 1" diameter of the wood dowel. This creates a nice flush transition at the wood to copper interface.

(Be sure to use 3/4" sweat to 1/2" threaded reducer fitting. The diameter of 3/4" sweat to 3/4" threaded fitting will be too large to fit through the ring used to assemble the seat.)



(1) Package of two part epoxy adhesive

- Brandname “JB Weld Epoxy” adhesive holds well on metal.

- Make sure to use the original JB Weld that requires 24 hours to cure.

- Do not use the quick cure (15 minute or less epoxies - including JB Weld Quick) as these

do not hold as well to metal





1: Use sand paper (or chisel, pocket knife, lath or beaver teeth) to reduce the diameter on one end of the Upper Section and Lower Section dowels to match the inside contour of the female copper fittings. The dowel ends should insert to the bottom of the threads on the female fittings.



Both ends of the Middle Section dowel should be reduced to fit the male copper fitting. This dowel should insert all the way to the end of the male cooper fittings. (The male fitting requires the dowel to have two step diameter reduction in order for the dowel to fit flush to the end of the fitting.)



Reference the last photo in this series.



2: Test fit the dowel in the copper fittings several times as you are reducing the dowel diameter. The dowel needs to press tightly into the fitting. Use a mallet to force the fittings on (be careful to not damage the threads.)



Note: The fitting will ultimately have to be removed to apply the adhesive. This is where the wrench flats on the fitting come in handy. Use them to twist off the fitting.



3: Remove the fittings and “roughen-up” the inside of the fitting with something sharp (like the bent point of a nail or a file.) The deeper the gouges / scores on the inside of the fitting the better the adhesive has something to grip onto.



4: Similarly,“roughen-up” the end of the wood dowel by making grooves to hold the adhesive.



5: Mix the adhesive per the package instructions. Protect the threads on the fitting with tape. Apply adhesive to the inside of the fittings, and the ends of the dowels. - Make sure adhesive does not get on the threads.



6: Pound the fittings on the dowel ends and clean-up any adhesive that oozes out. Again, make sure the threads are free of adhesive.
