Finishing Cabin Floor and a New Milestone

 I filled in some spots where the glue didn't quite flow all the way through.  Not structural so I used Famowood filler--takes 15 minutes to dry, vs 24 hours for thickened epoxy.

 Here is the same area after filled-in spots have been sanded.

 The floor has been covered with epoxy, except for the outer couple inches.  That is so the glue fillets will stick better when the floor is attached to the cabin walls.  (I feel compelled to mention something here about the application of multiple coats of epoxy.  I don't know why this is not mentioned in the book, but it is very important to get a good chemical bond on subsequent coats.  Rather than write about it myself, I refer you to the MAS Epoxies website FAQs: MAS Epoxies FAQ
Please read through FAQ 11. What is the Recoat Time? and FAQ 23. Checking for Hardness - Using the Rule of "Thumb."   Summarizing, the best chemical bond is achieved while the surface is still tacky--and no sanding is required. But, if you wait too long, a good chemical and mechanical bond can be achieved after tack but while you can still leave a thumbprint in the epoxy--light scuff sanding required.  Wait until the epoxy hardens and you will have to sand it for a mechanical bond only.  This is especially bad after the first wetting-out coat because you are bound to cut into the glass fibers while sanding, weakening them.)    

Here the floor has been placed on the shell and is being held in place with temporary drywall screws.  Plywood scraps are used to keep the screwheads from damaging the surface of the cabin shell.  

NOTE: The manual explains this step on page 109.  On page 118, they inform us that they had covered the underside of the screw-pads with packing tape so epoxy would not stick to them.  That would have been nice to know back on 109!  One of the advantages to reading the blog is, now YOU know.

Milestone:  The shell is rightside-up at last!

The only entrance for now is under the galley.  Once the doors have been sawed out, that particular opening will be covered with a transom.  For now, I have to go inside and fillet the floor to the walls, and a few other jobs. Then the mold cradle comes off for good.
