Deck Anchor Points.

I didn't read it properly, didn't realise it was 2 plates welded together. I guess there was no 4mm "in stock"

I can see why Martini is paying attention to this thread.

Thanks Guys.

Yep, the two bigger holes in the lower plate are so they can be plug welded to the upper plate, and the mounting holes are for countersunk screws, so are different sizes.

It would have obviously been better to use thicker plate in the first place, but as I picked up 18 of those 2mm thick Stainless discs for nothing, I needed to find a way to use them.
They are the scrap from where some holes have been Lazer cut in a plate, so you can also see the small cuts on the side where the Lazer started it's cut. I was going to weld them up but don't think I'll bother now.

The deck on my Ocean is @30mm thick, so I'll be routing a recess 5mm deep which will allow for the epoxy and sealant when the 4mm thick plates are dropped in. Obviously there will be a deeper hole in the middle of the recess to take the Acorn Nut welded on the back, but as I've reduced these in height to 18mm in my lathe they will not go right through the deck.

As you can see a Prototype has been knocked up.

So far I've managed to blag all the materials as other peoples waste. Although I had the Stainless M12 Acorn Nuts 'In Stock' from another project.

The Two 2mm plates are plug welded together and the Nuts welded on the back.

I know the water that gets in the hole will just sit there, but I'm happier with that than it draining down through the deck. In any case a quick blast with the pump will get most of it out.

More to follow.

Nasher, are you fixing these on top of the deck or underneath?

Recessed into the top of the deck and held down with 4 large countersunk screws.

They are only to hold cargo down so don't need to take the weight of the boat or anything.

I've almost finished all six now, and have made a jig to use with my router to get the correct sized recess.

I'll get an image of what I've done as a trial with a scrap of wood instead of the deck.

I think there's a way to fix them under the deck without too much trauma, I can try & explain how, if you've not passed the point of no return

Thanks anyway, but I'm a bit far along now.
Plus I've also realised that the gap between the underside of the deck and the top of the fuel tank is only about 1/4inch, so I don't have much room to play with.

Been hiding in the garage trying to take my mind off events of earlier this week by making these, but managing to get the boat from the yard to my house for a day whilst I use power tools will probably be a couple of weeks away, so the project is now on hold at this stage.

This is what I've ended up with.

Have you got anything to polish them up with? Will help a lot with resisting corrosion/tarnishing. Also I recommend tef-gel for the threads and in the countersinks for the same reason.

Nice job though!

These do a fantastic job of electro polishing & it's not too expensive. I've had bits & pieces done by them in the past. If you bead blast the parts first, the finish is even better.

[Nasher]

They've only had a very rough going over with wet and dry so far just to remove the worst of the marks.

I was planning to polish them up a bit better using the polishing mop I have on one end of my bench grinder. Trouble is, anything too shiny on 'The Nashers Revenge' tends to show the rest of the boat up.

Been there before, put a new nicely polished mudguard on a perfectly good useable motorbike once, and because the rest didn't look as good I ended up completely stripping it to restore it and had to buy another bike to use in the meen time

Fair do's. At the very least I'd pickle 'em or the welds might rust. It'd be a shame to spoil your efforts for a 'appeth of tar

This all looks very familiar Nasher...

Worked well for a rear bench seat so should be strong enough to tie down your aux...

I cant believe that post is nearly 5 years old. Doesn't time fly !...

Nasher hi

for the future since i saw you had a nice solution already...

the German company Niro Petersen has some kinky flush options (one with a ring and one with a removable boult thingy) they tend to charge you kilos instead of pounds for their gear..

Niro Petersen KG

by heart items number
1110 and 1111
or
1151 plus 1141

there are also semi flush 'anchor eyes' - i am considering to use them for my floor with the proper backing plate or anchoring below(which you cannot do i read) the deck since they have 2 boults/screws only:

4Uboot.nl - Home*::*Beslag*::*Wantogen*::*Verzonken want - ankeroog

Not sure which brand they are and if they/where they are to be found in the UK ..

the DIY option looks nice though ...

[Nasher]

After all this time I finally got round to recessing these in the deck today.

We've found a way to afford to keep 'The Nashers Revenge' for another year, so are hoping to take it to Devon this year if we ever get a summer.

Excuse the state of the rest of the deck, it needs a scrub, which I'll do next weekend when the Sikaflex has had a chance to dry properly.

Today was the first Sunday we've had in months with no rain, so it was a good oppertunity to crack on.

And with the rings in place.

Next job is to build a small rack to screw them into when they are not in place.

Now that is a bloody great idea. Nasher....

It has to be said you are never done working on a boat are you,,,,

It looks very nice - what diameter of thread have you used?

That's an interesting question because of what I ended up doing.

Going over the top as usual I used M12 Acorn nuts, but then when I saw the size of ready made M12 ring bolts the rings looked stupidly large.

So I brought some M10 Ring Nuts, drilled and tapped them out to M12, then welded a short length of M12 stainless studding in them to make M12 Ring Bolts with a sensible size ring - Hope that all makes sense.

And with the smaller Nashers engine strapped in using four of the anchor points.
