DivAir repair of ugly broken fiberglass body

Sun Dec 29, 2019 9:59 pm

I picked up a broken DivAir Model F that I fixed, using JBWeld. Here are some pics of the repair.

This is what all three broken out cover mount holes looked like, although I only show 2.

Here are some pics of the roughly repaired parts:

You have to love JB weld!
If all goes well, I will have an all new reg to unveil shortly. It's unlike any other that I am aware of.

Here's the original damage:

And the latest pic. Note the thicker rim at the repair::

I'm probably going to glue some stainless reinforcement plates on, something like this, although the patches seem really strong.

This DivAir is interesting, not only because of the brutalization it incurred, but that it seems to be a factory upgrade of a model "C", which had an aluminum body. The first models are bronze and the second models aluminum. The service company offered a low cost conversion of the metal DivAirs to fiberglass, due to the corrosion the metal bodies suffered. This one has a serial #C prefix, indicating that the cover was switched at least. The early models had really nice chrome on the covers, but the later ones had really thin coatings that blemish and wear thin very easily.

However, there are several other differences between this DivAir and another one I have which is definitely an original model "F". This one has a model A or C lever, and is missing a second lever adjuster screw.

Here's a pic of the model "F" and a model "C" for comparison the the broken one:

You might have noticed that the later lever, when pulled down by the diaphragm, covers the air channel better and directs air toward the intake horn for a better air flow.
