Week 08 before launch - Assembling sheerclamp & centerboardcase


12.10.-18.10.15

Assembling sheerclamp & centerboardcase



Bulkheads fitted and filleted (white lines)


 
I started the new week glueing the bulkheads onto their positions. The white lines show the fillets with thickened epoxy, which increases the laminationsurface of the bulkheads to the hull and give more strength to the construction. I admit, filleting I don't consider my favorite work, to be honest it's awful to put this sticky stuff in all the edges and corners.




 





Cutouts for inspection hatches
These are parts of the fore- and aft-buoyancy compartments sealed with epoxy three times. According to an advice of Mark, one of my coursecollegues, I cut the inspection-holes larger as drawn on the plans to get better access. 









 Tuesday was a very exiting day. The centerboardcase had to be fitted in and therefore a hole had to been cut out to fit it in. After numerous times of controlling - is it the right length, is it the right place, ... I started to cut and .....

I did it! The big hole in our boat
 .... the result was perfect.

The centerboardcase on its place



The blue-greenish colour you can see inside the centerboardcase are "Formicasheets", glued on the plywood as a protection. Moving up and down, the centerboard will rub towards the centerboardcase. The "formicasheets" are supposed to protect the wood of the centerboard against this abrasion.









The centerboardcase slotted into the gap exactly and was screwed and glued to the Companionwaybulkhead as well as to the hull and the hog.






The next step was to put the sheerclamps onto the inside of the sheerplanks to stiffen them up and as a base for the deckbeams.

Notches for the sheerclamp


First the notches for the sheerclamps have to be cut into the bulkheads.















Then the sheerclamp had to be produced. Therefore we glued 2 planks together and moulded them by clamping them on the outside of the sheerplank.

Quoting Steven: "Rule number 3, you never can have too much clamps"!


Using the hull as a mould for forming the sheerclamps

















The sheerclamps already on their place



It took me almost the whole next day to clean, sand and fit the two sheerclamps, so to be able to glue them on the inside of the sheerplank in the evening. But Thursday late in the evening they were glued and clamped.








As Ant was ill already the whole week and working alone your progress is limited I was happy that Darren and Mike helped me on friday.


Anchorbox, small bulkhead before centerboardcase and cockpitseats


Darren sheated the inside od the anchorbox with 200g wooven cloth against abrasion and Mike started to spile and cut the plywoodpeaces for the cockpit, while I spiled and cut the part bulkhead in front of the centerportcase and fitted the logs for the centerboardcase which are necessary to give it more strength.









The glueing of the logs and the bulkhead was done at Sunday. It would have been hard anyway to spend a whole weekend without beening in my loved workshop.
