Hms Alert by Maarten [COMPLETED BUILD]

Thx gents for all your comments and likes.

@Thomas Marocke it is depending on the type of resin you use. Yes the reaction of the chemicals create heat but the amount of heat is depending on the speed of the proces and the amount of resin. The quicker the resin is curing the more heat is created. In this case I used a quicker curing resin for the bottom part, curing in max 48 hrs and with this resin you can pour up to 3 cm max. The second pour I did with very slow resin which you can pour up to 10 cm and cures in 7 days.
Last factor is the room temperature which is perfect around 20-25 deg. Higher and the process speeds up with more heat as a result too cold and the process will never finish and the resin never cures.

As I had some crystals in the resin due to lower temperatures when stored so I had to heat up the resin in a bucket of warm water. Due to this I had more heat in the process then I anticipated resulting in some air bubbles around my anchor and some heat shrink at the corners of the mould.

But I like the result as of the anchor is just dropped over board.

I use tape for easy removal from the mould. I dont use release spray as these often contain grease or teflon which I am afraid can ruin the resin while getting into it during the pouring.
I will plane, sand and polish the outside surface after removal from the mould, but that will take another week.
 
a complete new way to construct a building board or jig for the model ...... main problem I see, that you can not use it for another model - and maybe also heavy

Great work - great idea - I am looking forward to see the result - btw: I like the bubbles also !!!
 
Today it is time to free my Alert from its mould.
The resin has set for 3 days so is hard enough.
As the mould was leaking it is now glued to the pallet that I used as plaform.
So serious tools are needed, guess nobody else used a crowbar on his Alert until now.

The fwd side is actually simple to remove, the tape did what it should do.

The same for the stem and stern.
Removing the plywood.

Followed by the tape.

The keel side is a different story.
This was covered with double sided tape to hold the model to it. This side also leaked resin, glueing everything together.

The majority of tape removed.

After cleaning tape remenants and leaked resin this is the result sofar. Now in a few days when the resin is fully cured I wil sand and polish it.

Sitting on my chair, otherwise I'd keel over. Marvelous!
 
Allthough I haven t been building a lot due to travelling lately and currently am in France for a week of skiing in the French alps.
Fortunately our hobby enables us to take small items with us so I have been working on the hinges for the doors.
This time I used the kit provided etched hinges.

To make these this is my travel workshop.
20211216_190147.jpg

The hinge I bend with a pointed pliers and tweezers around a 0,4 mm brass wire.
When working on the tiny highe parts I held them in a clamping scissor.
When both hinge parts are bent I join them with a 0,4 mm wire bended on both sides to keep them together.

After creating the hinges I cut of the bended wire and solder the ends.
Here all finished hinges ready for burnishing.

The wire end on the single hing is cut off after installation, this to avoid the part will be lost.
