I wasnt asking for your opinions of having handles or not but thanks anyway for the positive input. I was asking how/if it can be retrofitted and i hijacked this post so will search the forums history to avoid more negativity, have a great day everyone.
I wasn't initially responding to your request. Giving my opinion and reasons for it may be regarded as constructive in some quarters.
But since you seem to really want to know:
Get some stainless inserts.
Roughen the inserts with emery cloth.
Plug them with wax to stop resin getting in the threads.
Clean wax off around hole, thoroughly.
Use white spirits/acetone to clean insert.
Rout holes of appropriate depth and diameter.
Sand deck 2" around holes.
Chop up some glass cloth into short (15mm) lengths.
Cut three or for staggered size patches to match the sanded area of deck.
Mix epoxy thoroughly.
Put a couple tablespoons of resin in a separate container and work enough small chopped glass in so it's a bit thick.
Put some of this mix in each hole and work it around to saturate the whole surface area.
Push inserts in so that resin/glass mix pushes up and around them.
Remove excess.
Lay and wet out largest patches, then smaller.
To minimise sanding use a precut bit of plastic bag to lay over each section of glass.
Pad it down - not too firmly.
Let resin cure.
Remove plastic.
Lightly sand/feather any bumps.
Carefully drill out, countersink and sand smooth the glass over hole in each insert.
Remove wax with a bit of wire or something - do not heat!
Screw handle in.
