Fwd Vent Boxes & Hatch

When I first built the vent boxes and set them on the cabin top it became quite clear that the fwd boxes and the hatch cover were going to occupy the same space.  Hmmm... can't have that.

 

So ... I decided to raise the top of the hatch about 4 inches.  The sides angle in so the added height would give me more space between the hatch lid and the vent box.  Also, in doing this I can build a new cover with straigher sides than the old one.

With the wood glassed in place from the inside and 2 layers of glass sealing it it's time to glass in the outside and make it look original.

 

There ... the vent boxes are tacked in place and the hatch extention is ready to grind smooth.

Now, wash the deck down so the glass dust doesn't start another fire ! ! !

Next week I'll finish sand and lay down a layer of InterProtect 2000 barrier coat.

 

Ventilation Boxes

If you scroll down  many months ago to previous posts you can see when I made the ventilation boxes.  Last weekend I sanded off the paint and gelcoat in the area around where the boxes go.
Today I cut all the pieces of mat and cloth and got the aft two boxes glassed in place.  Tomorrow I'll glass on the middle two.  The fwd two will be more involved because they are very close the the fwd hatch and I'll need to raise the hatch edge so the lid doesn't hit the vent boxes.
