I also did a larger 6" x 12" sch. 40 that was donated to the church I was attending at the time and is used as the call to service bell. But as the old saying goes, life is what happens when you're planning to do other things and these parts languished in my storage building until last year when this project finally began.
The first step of course was to sit down at the computer and come up with a working design that I fully expected to refine as the job progressed. I decided early on that this was going to be a highly finished piece with pivot arms and a counterweight as is often seen with steeple bells.
One thing I do not have in my shop is a welder. Otherwise I would have done the welding myself. Fortunately I have a neighbor down the block who is a welding instructor at the local community college and I was able to persuade him to do the welding for me.

|Lots of fine detail work.|
It was now time to move on to what I call the counterweight pivot block assembly.
before attaching pivot arms.

coats of self-etching primer paint.
This assembly will be revisited after other other structures are completed.
|This final assembly required careful fitting and|
squaring up using half a dozen clamps.
This assembly was made from standard 2" x 4"s, 1" boards cut to various widths along with two pieces of 3/8" plywood cut into matching octagons holding the X-frame together. All these pieces were assembled with wood glue and deck screws. All the openings and gaps were filled with plastic wood. The finished sub-assemblies and final assembly were sanded smooth with 80 grit then 100 and finally 120 grit sandpaper.

The as designed center of gravity came in right on target at just under one inch below the centerline of the pivot shafts. The bell swings with ease and very little effort.
