Let the Sandinsanity begin

and the dust fly (again). Moved inside the boat to start cleaning up the seams etc. They all have to be sanded smooth to get them ready for fillets & tape. I used pretty much every sander in my repertoire and my electric hand planer as well! :-)
Didn't take long to fill the boat with dust to the point I couldn't see what I was doing. Up and out again to fetch R2D2. This poor old shop vac has been with me for almost 30 years. It's seen duty from sanding car paint off of a bedroom wall (tenants *sigh*) to evacuating backed up toilets and now it's being pressed into service for the first time on the boat.
Just before lunch break I stopped sanding and laid back to look at the shed roof trying to figure out how we're going to recover it tomorrow. It was so peaceful and quiet and relaxing I fell asleep! :-)
One just has to stop and admire their own handiwork every once in awhile!

More Sandinsanity to come.

Another Serious WTF

Got the keel blocked up yesterday and the cross bracing/form out of the way today. I had to bodge together a set of steps to get into and out of the boat this morning. Decided to take a pause to reflect on my handiwork and had another one of those WTF have I gotten myself into moments.
Sitting pretty much where the head will be. A likely spot for a respite from the rigors of boat building! :-)  I corrected these photos for fisheye and it makes the hull look longer and narrower than it really is.
Approx. location of the helm position. I think the deck will be about 20" higher once it's installed.
I think where I'm standing above is Station H which is the aft bulkhead for the main cabin. Everything aft of that is cockpit.

Had to call it quits for today. Got errands to run etc. Back at it tomorrow. I have a date with my belt sander!

Thanks for looking in.

Video from yesterdays flip

Here's the edited video from yesterdays flip. The 'crash boom' happens just after the 6 minute mark. Only casualties were a 2x3 & my undershorts. Boat is fine and no one got hurt.

Carry on....

With a little help from my friends - Flipping the hull

Well today was the day. Nothing left to do but flip the hull over. The team assembled and we got right to it after some accusations of me stalling!

I apologize for having to use screen captures from the video. I was a little too busy to be taking pictures.
Finishing the first part of the lift, up on a 45 deg angle and resting against the work bench & stack of bulkheads. It got hung up a bit. We are pulling the bottom of the lifting frame sideways as we lift.
Over on its side. It did exactly what I thought it would do, slide down uncontrolled. We had moved the tag lines to the other side thinking they were needed there to help control the roll from the top. She slid down with a boom but nothing or nobody got hurt.
The second pull with the ratchet strap went a lot slower. We had to reposition it higher on the gin pole to get the lift we needed. It worked really well, much more control over the hull as we inched the bottom of the frames towards the gin pole and payed out on the main hoist.
And after some repositioning slowly lowered to the ground.
Finally, upright! It's taken 3 years to get to this point (we have short building seasons up here). The only casualties were one 2X3 and a pair of underwear.

Special thanks to the 'crew':

Greg Kroone, Tim Gilligan, Robert Taylor, Jim Campbell, Mike Laporte & Doug Laporte.

Now the real works begins.........

Journal of the Molly B

While researching option on how to flip my boat hull I stumbled across the Journal of the Molly B. The Molly B is a modified Glen-L Argosy which the builder, Tom Schmidt, built starting way back in 2002. I immediately purchased and downloaded the first three of his journals to see what info I could glean from it's pages. With Tom's permission here are some of the photos and details of how he flipped his 40' hull.

First thing you'll likely notice are the rolling frames and Gin Pole. These allow the hull to be flipped basically within it's own shadow. The hull Tom built has much of it's framing already installed so there's no need to overdo the rolling frames. He's pulling from a single point with a chain hoist in much the same manner I'll lift my hull.

Up she goes. As the main hoist lifts the hull the bottom rolling frames will want to move towards the gin pole. In my instance where I don't have a whole lot of extra room we'll pull the bottom as we lift.

In the above pic you can see the internal structure in the hull. The rolling frames and lifting points are tied to these (temporarily). They provide the structural integrity to the hull as it's lifted. At the point the hull is in that pic there's the greatest force being applied to the hull trying to collapse it.

This is the point of no return. The boat will go to the floor. The maximum stress on the gin pole is also at this point when the hoist is at max extension. The tendency will be for the rolling frames to want to scoot out from underneath the boat towards the gin pole dropping the hull to the ground. I've planned for this and will have a couple of bodies with tag lines standing by to arrest the slide if it happens.

So in a nutshell that's how it works. Looks easy. In theory it is. In practice, well we'll see how it goes.
