Float cradles assembled

Just a brief post to cover putting the float cradles together.

I have seen some really nice looking float cradles on the web, that look CNC cut and robust enough to hold up the Titanic. For awhile I was thinking that I had to create some cradles that kept up the tradition, and this was slowing me down a bit. This evening after work I got exasperated with myself and said "just build something, dang it". So I did.

I did have one good idea (for me anyway) which was that I could use the form frames themselves (#5 and #9 of course) as patterns:

This let me avoid having to get the form frame full size patterns out. Of course, the form frame lines are 3/4" off from the real hull (battens). So I scribed a line 1/2" inside of the frame lines, to give a little wiggle room, then cut out those parts with a jig saw. I cut out two pieces per cradle, and screwed them together so the float had a nice thick base to sit on. The cutouts formed little half-moons which I then used as side-braces:

A little bit of work later, including smoothing over all the edges with the sander, and I had a little family of these guys:

You can tell I wasn't being too precise with my jigsaw work, so some of the lines are a bit rough. Not worried about that, but I am wondering if they will be stable enough when I start sanding the hulls and whatnot. We'll see, if not I can always add some long side braces. I'm still debating about what color stain to go with (joke).

Here's the port float sitting up on the cradles:

(that's my sixteen year old son in the background, sorry for blocking your head out Zach.)

I can tell already, that finishing the keel taping from the upright position is definitely the way to go; looks like even the bow bulkhead would be pretty accessible like this.

Here's an aft shot:

Obviously I have some deck flange and transom trimming left to do. I have to say though, it was pretty motivating to see that float sitting nice and upright!

Really nice cradles! I think I will make a set of those as well.

Jay -
Have enjoyed following your project for the last several weeks since I found it. Looks great! I am expecting / hoping to start my own F22 project in the fall (following Henny's advice and finishing remodel projects around the house first). As I live in Ballard, I was wondering about visiting your project? I know time in the shed is precious, but seeing your accomplishments would be exciting and informative for me.

Visitors are most welcome. Please email me at boatboy22@verizon.net and we'll work out a convienent time for you to stop by. (Hmm, I may stall you for a few weeks until I 'm ready to have help with the fairing...just kidding!)

Looking great....to scribe such lines at a distance I have a collection of various size washers some hand made.As a young design grade ( a long time ago when drafting boards where the norm) at my first place of employment I watched as the art department head carefully drew lines and archs around a vacuumed formed piece so that the die cutter would have a pattern to follow when making up the cutting die. I said hang on a sec Bob….I went in to the shop and grabbed some washers…. Came back stuck my pen in the hole of the washer pushed it up to the various formed pieces and followed there shape drawing a beautiful flange all around the parts. He looked at me and said where have you been for 20 years. I have no idea where I first saw this done but to this day it can still blow people away.

se work great.
