RIBase
Blind Big Head nuts

I am think about how to install blind Big heads to the deck of my rib so as to allow for the changing of the seats, dive bottles etc.

Option 1
Screw and sika flex to the deck as is.

Option 2
Screw and skia flex to the deck as is and glass over with the resulting hump.

Option 3

Grind back the fibreglass back to the ply wood about 6" all around the big head. screw to plywood and glass over. This option should leave a reasonable smooth deck without the hump in option 2.

Any thoughts /advice would be great

I installed a pair of threaded inserts into my deck to re-attach the a-frame after the original screws pulled out (was a very rough day and the old fixings were 20 years old). The inserts have a coarse thread on the outside and a metric thread (M8 in mine) through the middle and are installed with an allen key. I glued them in with epoxy for good measure. The centre holes are all the way through but a blob of sika of epoxy at the end before fitting would fix that, if it is a problem. These are the ones I used and are made from 304 (A2) stainless so not quite as strong as 316/A4 but should be up to the job. Just add a few more if possible:-

I plan to make my own from 316 bar when I finally get the lathe up and running.

If its to hold seats down then the only way to do properly is to cut a hole in the deck and fit from beneath. Then fit a stainless plate over the hole or glass the removed disk back in and paint over with non slip deck paint...
