Well, I've ran into a bit of an issue with the prop valve placement. It is too low. The outlet for the front brake line I need to plug is to close to the bracket underneath it. I didn't think it would be a problem finding a low profile inverted flare plug to fill the hole but I have found nothing that will work. The regular plugs are to tall and I do not want to remake the bracket OR the hardlines, so.... I will make a low profile plug.
I puttered around in the shop last night trying to figure out how to tighten the plug and came up with this. I bored a .177 diameter hole in a test piece of aluminum.

Then I used a short Torx bit to "broach" a hole for the driver. I started it with a few taps from a hammer to make sure it was straight then just pressed it into the test piece with the 4" vise.

This worked great! I have some 3/8-24 threaded brass rod coming from McMaster Carr today. Hopefully the technique will work as well on the brass.

Making the inverted flare side is easy. A 3/16 drill and 90degree c'sink work perfect for that. Getting the "driver" side done will be the challenge.
