Can you upside down re-mount a Webasto?

That other thread reminds me of my Winter Challenge.

Bloke that fitted my Webasto, six or seven years ago did a good job - nice, tidy fitting, etc.

But - he glued a ply pad on the cockpit locker 'deckhead' and then screwed the Webasto to it.

This summer, the glue gave way, so it's suspended an inch below, supported by the pipework - great for reducing vibration, but not structurally sound.

I need a creative way to exert maybe 20-30Kg force upwards, right into the gunwale-hollow, after applying epoxy or No More Nails on a 14"*8" pad, through a 1" gap, with about 3" clearance on one side.

An angled stick might apply the glue, and something involving a Spanish windlass and some 3' hazel or some such sticks braced in the bottom of the locker (or a monopod) might work - any suggestions?

(I'm lacking enough meccano to make proper mini-scafolding)

Yes, I could dismantle the whole thing, but, well, then I'd need to re-mantle it ;-)

Car jack and a bit of pole?, though frankly if it has given way after the guy did a "good job" with proper access without the heater in the way I would be looking at a mechanical fixing, or at least dismantling, cleaning and roughening the pad and other surface up properly and being prepared to do it all again down the line.

Thanks - I think you're right. I'd prefer not to go for mechanical fixing, 'tho I know it would be better.

I guess a good clean with white spirit(?) and roughing with a wire brush is next best.

The reason why it's come off (I think) is the rough flow-coat on the deckhead - *that's* still glued to the pad...

Any particular recommendations for type of glue? Is it worth glassing it?
 
I fibreglassed mine in' Don't really want that falling off and cooking the boat!
Loads of the 'new' adhesives would easilly do it like 'Gorilla glue' or 'sticks like s***' , google them.
 
Jack to push board back in place

You might consider using a piece of 10mm or 3/8 threaded rod. Get a piece of tubing, both suitable length. Put a nut and washer on the threaded rod and slip the tubing over it. Wind the nut out pushing the washer and tubing to extend the length. Just a thought good luck olewill
 
Do you want to upside down remount the Webasto, or remount the Webasto upside down.

One will be a lot less likely to induce a headache.
 
Are you absolutely sure mechanical is out of the question? There are some quite tidy looking low profile coach bolt heads around, or if the other side is teak laid you could counter bore and plug it after fixing. Modern adhesives are really good but if the substrate it's stuck to just pulls off as it has done already it is likely to happen again I suspect, so it would mean going back to good lay up through the flowcoat to make a good bond, probably more work that a neat mechanical solution, you could always do both using small size screws.

Finally got round to it today - stripped heater off (and hoovered out half of Ryde sands after removing kids beach toys (in dive bag) from cockpit locker...)

No teak - just a ~8mm fiberglass deck, but I cleaned it all up and got a couple of small, wide screws through the ply and ~5mm into the deck head. That should at least take the weight of the pad while the fast-grab glue, err fast grabs.

Full re-mantleing will come next week - thanks for the replies.
