Brief Description:  Cowl Inlet Rings: Part 3

Although the end result is to have the rings be only 'mechanically' (not chemically) held in place on the nose-bowl with epoxy, the small ring of epoxy that I pour in there will be permanently attached to the nose-bowl. So, there are no second chances with this procedure.

So I had to 'test' a couple of parameters. One is the mold release. I have no experience with mold release products because I've never wanted the bonded parts to come apart before. So I got a scrap piece of aluminum angle and put a grove in it, using the table-saw set-up I showed in part 2. I then gave the piece a couple of coats of a Maguire's carnuba wax product for cars. I made sure not to get 'cleaner wax' products, as all the online discussions said you really need the carnuba wax to be just wax. This product has some petrolueum distillates in it to help with application, but when it dries it should leave mostly wax. I didn't go with dedicated 'mold release' because 1) I was impatient and didn't want to wait fomail-order stuff to show up, 2) it was going to be far too much stuff for my tiny project and I didn't want yet another chemical added to my pantry of old chemicals in the garage, and 3) I could use the left over car wax product for our airplane club's wash and wax in October.

The other part of the 'test' was also going to see if my 15-yr-old two-part epoxy was still good.

Image 1 shows the two pieces 12 hours later: Success!! The parts came apart with very little force, and I am thrilled with how the mixture 'picked up' the detail of the groove. When the two are mated, the groove solidly stops any motion perpendicular to the groove. We're now ready to try it on the real thing!
