No worries mate. Sharks ate all the crocs!

Well I made some more progress today ; there's still some more details I can add but I want to get the second beaching gear oleo caught up to the first before moving on w/ more details.
And also I want to get the other three Struts mounted to the fuse; and all four mounted to the wings.

It may not seem like I've done much but this is harder than it looks there's quite a few Variables involved with the mounting; angle, pitch, yaw, height and pin alignment.

How have you anchored that bottom bracket inside the plane?
I can see that being a leak point no matter how well you seal it on the outside. Are you going to completely cover the bracket inside with something to create the seal?

No worries I'm confused all the time LOL .... about half were strictly flying boats w/ NO wheels; The wheels were an after thought - adaptation.

Snake there is a hole drilled into the fuse along side a former I'll glue in the brass tube & plate w/ E-6000; THIS GLUE IS WATERPROOF and bonds just about anything to anything.
I'm also thinking of insetting the brass plate into the fuse 1/32" flush w/ the hull.

Thank you Bart I hadn't seen that video wish it showed more those type of things are very scarce
I would love to see them putting on the beaching gear and pulling her out on to the beach.

There's quite a few guys / people that think these planes all had the amphibious capabilities from the start; I think the marines need a plane that could go ashore in the south Pacific, so they requested them to modify the PBY.

Yeah, that video was just anoying! lol.
It showed them dragging one of the forward beaching gears out to the plane, THEN IT STOPPED!!! But I was right, the wheels exerted enough lift to make it float, how the hell did they manage to swing it down against the boyancy to get the bottom bracket attatched???

You know I was meaning the bottom bracket of the beaching gear don't you? The one that looks like it's just a sheet of brass in the hull edgeways... I'm assuming it goes all the way through the hull and is fixed inside by pins onto the framework or something?

It seems that water was added to the inner tubes of the tyres of the main beaching gear. I'm guessing that by doing this the buoyancy of the latter was adjusted so submerging the two was easily achieved by just one man.

The image below is from the Catalina Maintenance manual. A considerable quantity of water was added to each tyre.

For what it's worth in late RAAF service amphibians were allocated because that's all they made in the later part of WW2, and they were locally re-converted to true Flying Boats. This was done to increase range. The picture below shows a late Canso so modified. The particular aircraft was used to survey a possible postwar air route to the UK via Chile using JATO rockets for the open ocean takeoff from such stopovers as Easter Island. The upper beaching gear connection is clearly visible.

A propeller coming off is going to be catastrophic to the aircraft in so many other ways anyway.

These birds were well able to fly with only one engine, if a little underpowered lol.
