HMS Sirius 1797 by paulsutcliffe - 1:48 - POF from NMM plans

Difficult to explain the glue swelling, Paul.  Titebond II is a waterproof glue.  I paint acrlic over it all the time.  Could it be the sanding sealer?  Curious problem.

I am wondering if the water has somehow affected the wood strips (ie.e swelling when wet, shrinking when dry) while the glue remains unaffected.

Assuming your wood strips swell first and take the glued edges with it.

Then the wood shrinks (drying of water) while the glued edges remain in position?

 

Not sure if i am making sense here, but just a thought.

[paulsutcliffe]

Hi Ed, I'm not sure either, I'm using Liberon sealer which is a spirit sanding sealer containing ethanol, resin acids and rosin acids??

 

Hi landrotten I don't think there was enough water in the paint to make the planks swell and shrunk but could be wrong, personally I think its something to do with the sealer as Ed said, but again not sure

 

It is quite a nice look though however it came about and actually looks like I caulked the seams properly !!

 

Thanks all for the likes and comments

100% chance of rain all day today guess where I will be all day

Made a centering marker out of some pieces if boxwood I had in the stash after reading on another log somewhere about them

Also found a use for the spare handle I made for the wife

Decided it was time to start the channels as I am working around the ship, cutting the rebate into the waist rail in situ as I hadn't done them when building the Hull as a bit perilious but going slowly I managed

Fore channel being shaped from a piece of pear

 

And having the edge scraped

After one coat of sanding sealer

I cut the pearwood both ways with the grain and as this one across, from a strength point of view I should be using the other piece but the grain on this looks awesome and as I'm not going to be doing rigging on the model should be strong enough, I'm going to cut the edge off and file in the rebates for the chains

[druxey]

The suspicion raised about the one of the components of sanding sealer reacting with Titebond II might be your answer.

[paulsutcliffe]

Thanks Druxey, I'm thinking the same, I might stick some plank together and see if I can recreate the problem

Paul

Air gaps have been sanded into the back, drilled for fixing bolts, test fitted to the side

Cutting the mortices in the breast beam for the stanchions

The cross piece will be cut in half making the two sides but I'm keeping whole until all mortices etc are cut to keep the spacing

Port Side morticed in starboard still ti cut in, After dropping two stanchion down into the depths I thought I had better cover the gun deck before i lose it

Regards

Paul

 

[paulsutcliffe]

I also started on the main channel using cross cut pear same as the fore channel, look at the grain beautiful isn't it

Its amazing now the addition of a few pieces makes it all start to look like a ship and it starts to come together, all starboard channels are now made and have bolts nothing glued as yet as I have to work out how to make the supporters

From the bow

Mizzen

Main and stool

Fore

And a little test with a boxwood deadeye, I noticed some scratches on the fore channel and removed it to refinish, this is what I'm using for polishing up the pear to a smooth shine from left to right finishing with 0000 wire wool

Experiment to try and recreate the caulking lines as per the Cheerful, four beech planks all have had three coats of sanding sealer smoothed inbetween

Right hand side(bottom) also had some oil rubbed in and then painted on top, I'm sure the colour doesn't matter as its still acrylic

Left hand side is straight paint well watered down as per landrottens suggestion

As yet no reaction like my cheerful Hull, only difference is this is beech and the Hull is holly, could that have anything to do with it??? And still needs a few more coats of paint

You need to replicate what you did in every way to begin to determine what happened, Paul. Change one factor and you change the experiment.

[paulsutcliffe]

Of course you are correct Druxey, I didn't think the wood would matter as seemed to be something to do with the glue, however I will do again tomorrow with some holly strips

Thanks

 

[druxey]

It's the mix of all the items you used that may be the problem. If other wood species do not cause the effect you had, it would have to be the combination of the holly and other items in the stew!

[paulsutcliffe]

Holly strips are glued up and ready to go, meanwhile I made the two steam gratings for the forecastle

Coamings are ebony and boxwood grating, cambered to match the deck planking, knees on starboard also finished and bolted, work on the waterway has also started with its lovely curved scarph

Regards

Paul

[paulsutcliffe]

Second plank experiment, Holly strips, titebond dark glue with 3b pencil highlights, two flats of sanding sealer flatted between, so far no raising of the lines

Also at the bottom first and second attempt at belfry roof in ebony and one coat of sanding sealer

Thanks

Paul

[paulsutcliffe]

Ebony has been polished down to 5000 grit sandpaper and second coat of sealer added

Regards

Paul

Nice work on the ebony Paul.

I like that scraper ('s). Gonna have to learn about that. 

 

Jim

[paulsutcliffe]

Hi Jim @Jimt

The scraper is just a hacksaw blade trimmed to different shapes with another saw and files where necessary, I even have the ends trimmed for doing a bead in awkward places

I have also started turning the legs for the belfry, according to my plans they are only 2 ft.(12mm) High, 6"(3mm) wide at the base, I can't quite get the taper yet but I have got the shape down from the plan, I also scraped around the edge of the roof, could only manage one line though in the space.

Paul, what are you using for sanding sealer?  There are many varieties.  Titebond glue is resistant to most finishes, but as we know, our favorite "ungluer" - isopropyl alcohol - will soften it - and probably swell it in the process.  Perhaps the sealer had this effect.  Also, if the glue joints on the curved hull were not tightly fit and the gaps filled with glue, that would be different from your tightly matched straight joint lines on the test piece.  Another possibility: you mentioned dark glue.  Is this purchased as dark glue or coloring mixed into the normal Titebond.  If the latter, what is the colorant?  Which grade of Titebond?   Just some other things to consider.

 

Ed

 

Added note: Apologies, Paul, I see you have already answered some of these questions and I missed that.  I would say that the alcohol-based sealer is a prime suspect, especially if the joint gaps were filled with glue.

Thanks Ed, I have another piece of Holly strips on the go to experiment on, hopefully done exactly the same as the planking

Meanwhile as its -2 outside in the garage I managed to persuade the boss to allow me to bring the rope rocket inside to do some more practise on the rope making

This is with the dmc ecru no 40 thread supplied by chuck with the rocket

Called in at the local auction place last week and came across these, just had to bid

Work on the belfry has continued, not my finest piece of work and needs a lot of clean up, made the bell from the end of a brass cannon from a previous model

2 days in the shipyard and a lot achieved for a change

Port lids have hinges, channel supporters fabricated and attached on mizzen, dry fitted on main ready for painting

[paulsutcliffe]

2 chains fitted on the main channel to work out the lengths to make the rest of the chains and where they line up on the Hull
