Momentus occasion folks. Talked and talked about this day forever. Schemed and dreamed of apparatus and technique to get this #1400+ plywood and epoxy bowl flipped over. Finally settled on building a cradle, lag bolted to the frame, carpet lined and will be left in place (bottom portion only) until shes rolled out for good.
Steps:
So here is how this post will go. Mostly pictures with comments. Not much else. Its mostly action so a long, drawn out explanation makes little sense...

| Here you see the cradle constructed out of a combination of 2" x 6" and 2" x 12" scrap lumber. the 12" stuff is notched for the keel and the bottom, green 2" x 6" is bolted to the frame via a stub piece of 2" x 4" bolted to a frame (you will see better in last photo. Jacks are being used to lift the boat off of the ladder frame underneath which must be wrecked out before turning. |

| Here is the opposite side with a large tie down ring bolted to the 2" x 6" and the hoist attached. |

Can't see the chain hoist but it is hooked into a piece of chain looped around the truss above the hole that was bored into the ceiling. We made new holes in the ceiling later. Lots of ventilation now!
She's up and starting to slide a little to the right, like we want but needed help. using a come along we winched the bottom toward the right and continued to lift straight up. the chain hoists were slow which gave us a lot of control.
Another view of the same angle. In this view you can see that the far upper right corner of the cradle has embedded itself in the ceiling. sawzall came in handy to remove "offending corners". The cradle ended up being trimmed back quite a bit.

Here it is. Its bottom to never see the sun again (we hope). The process took us around 3 hours and could have gone faster but had to regroup a few times to figure out what to do next or how to address a problem or two (mainly ceiling height). Time for construction again.

Good job so far. I to am using CAD for figuring out issues. The plans were a bit sparse in my opinion. I wonder how your positioning of the motor will affect trim. I saw a 21' Redwing that the motor mounted on the transom and it trimmed out very aft heavy. You might want to consider some ballast behind the stem. Maybe a water ballast that you can change.
ReplyDeleteI'm starting my build this month I hope. I'll be glad to get started. I'm going to extend my canopy aft though and enclose with canvas for bad weather.
I too worried with the idea of moving the outboard aft and contacted the designer. He stated that the Redwing could do with some ballast forward and I have located the water tanks (80 gallons) under the V berth along with the water heater at the peak. All of this will of course vary as it is used and re-filled on an extended trip so I plan to add lead ballast as needed to trim permanently. I have also moved the batteries to a watertight compartment under the self draining cockpit sole at the pilothouse back wall and have tried to center the weight as nearly amidships as possible. Guess I'll have to get her in the water and ballast accordingly. Thanks for commenting and good luck with your build. Lots of work but very satisfying.
