I wouldn't wish that on you, Nenad.  

 

I did the cradle stand on my Wasa/Vasa and only epoxied the stand at four points to the hull.  The ship sat out for several years before I got the case and I never had a problem. A bigger problem were idiots to saw it and wanted to move the rudder.  Grrrrrrrr.....    So maybe you don't need the heavy screws and glue?

Epoxy and microballoons is an excellent filler and should not shrink much.
It's also lightweight.
Hobby shops that sell RC planes might have microballoons.

 

Back in the 80s when I used to build windsufingboards, you used to be able to by them in the surf shop in larger amounts, as well as epoxy resin.
Probably not likely these days, I don't know.
If you use microballoons, wear a mask. They are actually made of glass, and can fly around like dust. You do not want to breathe glass balloons..

Thanks for your support, dear friends

 

Do you know who will win next Nobel prize for astronomy ?

 

I found a black hole, here on earth. More correct, four of them

They swallow everytging I put inside

 

Filling continues

Maybe I am missing something here Nenad. Seems to me like those large screws are such a serious overkill. I have ships that have been sitting in custom cradles for years with nothing but a single dowel securing them.

Having said that, I would think some type of rubber washer fitted snugly into those four holes might be a very simple, and effective solution.

If I could drop over, we would have a few drinks, smoke a few cigarettes, and knock this issue out of the park before you know it.

Then we could have another couple of drinks and smokes for good measure. :)

Dowel is main idea. I am fighting now to make some "meat" for dowel inside large space under holes. It is necessary because I used balsa planking (?!?!)/Considering possible angle of holes in stand, simple one dowel can not be mounted, so here will be kind a "dowel for dowel" or "dowel in dowel"

I will re-post what I deleted yesterday. The only way I can see to put some meat inside the hull using your existing hole, is to form a thin-walled cup from some flexible rubber type of material. I would try making a form from what you have on hand in the shape of a flat bottomed cone. The idea is that you can insert the rubber cone inside the hull through the existing hull by rolling it up. When you get the cup inside the hull and opened up you will need a way to pull it firmly against the hull, I thought of using 4 o5 small wires placed around the bottom of the cup, long enough to pull the cup against the hull, then bending them over as an anchor, those wire would need to be part of the bundle inserted through the hole. will need adhesive around the lips of the cup to attach it to the inside hull. When the cups are securely in place, fill them with the material of your choice. The coned cups if sized right should provide for a surface contact with the inside of the hull at least 4 times the area of the drilled hole. Roll this around in your mind and put your own ideas into it, then test and do. I have no doubt you will solve your mounting hole problem, you are good at working through things like this.

Thinking about your hull mounting I wonder if a small dowel with a hole through the middle and some hose or tube connected to it like this diagram then if you were to force some epoxy down the tube it would overflow inside and create a large washer like surround. similar to a wall mount in plasterboard.

Just an Idea.

or even better yet......how about fitting those holes with the same size dowel plugs........1/2 inch to 1 inch long should do it.    cement them in place and then drill a center hole in all of them,  about the size of your screws.   then you'll have something for the screws to bite into when securing the stand.

 

you gotta figure that all the glue and stuff you've put into the hull,  has added some ballast.........how much more does that hull weigh?

Here are me again. Couple of days I was pretty quiet, because I have got a little flue, and also there was not visible progress.  Today I can proudly pronounce that my four "black holes" losed their "black" atributes, and have turned in regular holes, with bottom I can reach. Filling is slowly coming to end.

 

 

You will get it my friend. Cheers.

 

 

I know it Dave, but it needs a time for filling material to dry, and I have to work in thin layers, to avoid danger of leaking glue etc etc through deck planking. Her Majesty is turned upside down, I suppose - a last time in Her life time, and holes are opened to up during filling process. So, put one relative thin layer of material, and must wait for it to dry. And on that way, every day. about hour for four holes. The end is on horizon ...

Helo Jud, I have readed your post before you deleted it. I used rolled paper sodden with glue cleated to bottom of hole, and covered with thin layer of BBQ strip pieces, with another thin coat of glue. Idea with wire is something valuable to think about. So, bunch of strips rise over time, and now it is only 1-2 cm under hole entrance, so final filling can start

I was thinking about epoxy, Michael, but I gave up, because I was afraid of leaking through the deck planking. Particularly, I can not find in near shops adequate epoxy. In Belgrade there are not shops like "Hobby-lobby" and another such a type I have read on MSW, there are only a few similar, but with poor choice of such a things, materials tools etc etc ( mainly plastic kits, acrylic, brushes, cheep Chinese scalpels etc etc). So I have to manage with things I have

My idea is similar Denis : to fill hole with material  to the top, when dry and harden, drill through a new hole for 4mm dowel, drill 1-1,5mm hole in dowel, glue dowel in new hole and align it to the surface of hull. And after that mount stand with screw or a new thin dowel, or wire. Just for remind, main problem is balsa 2x5mm strips used for hull planking   

 

 

Hi Nenad,

 

perhaps the hollow-room dowel for M3 screw may be useful for your purpose.....

 

replace the hook by a M3 screw

Nils

 

Hello Nils. That was my first idea, and I made some testing with such a solution, but I was scarred of possibility that balsa strips can not withstand direct force. That was a reason I decided to reduce that direct force giving some "meat" to  hold dowel and to distribute direct force from hole entrance to whole "meat" in which dowel will be embedded. Problem is  in fact that I know with whom I am dealing with ... un patience, and awkward Nenad, and I just have to make something strong enough to keep me and my work from - me

 

So, another booooring period is coming to end, and I hope soon to continue with deck stuff challenges

I added extra ballast earlier, my friend, so I think whole thing now has a little less than 1 kg

Ah yeas Nenad, you are not disappointing us, I figured you'd come up with a solution with materials you have on hand.  It's a handicap you'll have to work around and so far you have come up with some brilliant ideas.  My hat off to you and your perseverance.  

Your solution will work just fine, have patience and go slow - you don't have to rush on our account.

 

Cheers,

Thank you for nice and supporting words, Piet. In my life, I graduated improvisation for many reasons. Also, when I make something, I have a irrational fear that structure will be weak, and usually I made it more stronger and complicated than it has to be. I remember when kids were babies, year 1993. full force of hyperinflation, and no money for anything... we just moved in our semi-finished house, with no furniture. I found some cheap pine lumber and made beds for babies ... thinking ... they will jump on beds ... they had to be very strong ... you just can not have any idea what wooden fortress I have made ... Also, our double bed in sleeping room has hidden metal structure and can withstand  weight of one tone !!!! You can easily hang yourself on any bookshelf I put on walls ... every concrete I have made in and around of house is much stronger than it had to be ... 

 

That is just - me, and my irrational approach   to everything I make/made . This time, transposed to my model

 

Thanks again

The best colateral thing is, that throne can enter into Her dust protecting wall shelf

She looks mighty fine on her throne Nenad, mighty fine.

We are all awaiting further construction on her majesty.

 

Cheers,

 

 

very pleased to see that there's a happy ending ..........the queen lives!

 

 

I am also surprised how good she looks ! Ok, some trifle here and there, some color correction on standing, but it is really OK
