HMS Victory by Y.T.- Mamoli - 1:90 scale

[NMBROOK]

Excellent work YT,As you have chosen to us wood as your pattern,I would wipe over with oil to prevent it sticking to the mould.I made a boxwood master when doing some resin casting on Royal Caroline and wiped it over with vegetable oil I raided out of the kitchen.It worked despite my Wife's cursing about stuff going missing into the abyss (my workshop)

Kind Regards

I wood wipe over with oil to prevent it sticking to the mould

Thanks Nigel. I will do so. These parts I made are so brittle.

This is a great tutorial Y.T. many thanks from all of us! ... Oh... as Nigel mentioned, please use Admiral's vegetable oil cautiously... we need you alive, to continue this build log and show us step by step casting

My wife Marina is at all not vicious Admiral. We both have innocent hobbies and these hobbies maintain perfect harmony in our household. Whenever I show her what I do on my model she always tells me I buried my well hidden jeweller's talent.

...I must agree with Marina.

I just scratch built (carved in wood) my master rigols which I will replicate by casting epoxy putty into mould.

Well done, mate! Those look great.

Oyumaru moulding clay had arrived and whole yesterday I was experimenting with making moulds for rigols. Oyumaru is warmed up in water at 80 deg. C for at least 3 minutes. At that temperature it becomes gooey and suitable for forming. Good thing about this stuff it is reusable as many times as you want. I discovered it is not easy to get decent mould with proper detailing and with no defects. I had to modify my moulding pattern by gluing rigols to wood board. It appeared to be impossible to get good mould of two pieces together as per my pattern. It was also not possible to make a thick mould. I ended up by making a dozen individual small moulds of each rigol type. They turn out to be of good quality. Now I am waiting for an epoxy putty to arrive so I can make my rigol parts.

I am just catching up on your Victory. You have really overcome many obstacles of the kit and it shows really well what you have accomplished. It is showing us a beautiful model indeed.

Hi YT
I have never come across Oyumaru before.Has it set hard or is it flexible?Just thinking of if you can flex the mould to get the rigol out without breaking it.

Kind Regards

Nigel

Oyumaru when hardened is flexible as rubber.

So this could also be used for casting gun barrels?

 

[Y.T.]

100% can make cannon barrels or any other small parts but two part moulding should be used for barrels. Here is video how:

Here is that cabinet where compasses were held on the ship of that time. It is 1:90 scale. I modified a set at 1:72 from Master Korabel (bought it for $5 on eBay). Of course I had to redesign every part to shrink this cabinet down by about 33%.

Hello Y.T. The compass cabinet looks extremely accurate and authentic! Well done!

 

[Heinrich]

Wow! I can see why your Admiral refers to "jeweller's talent". That is amazingly accurate miniature craftsmanship! Very well done, Y.T.

 

[NMBROOK]

Wonderful,very nice work indeed YT.Just out of curiosity,what was the original Mamoli design?

Kind Regards

Nigel

 

[Y.T.]

Mamoli design for comparison.

That looks like a domino brick.
Yours is excellent, Nelson would be proud at you.

I continue working on challenges wood kit presents. I am still waiting on arrival of my Epoxy Putty for casting wriggles - guards over ports. It suddenly occurred to me I have this wood filler paste I never used on my wood hulls. I thought why I cannot try to cast this stuff into my moulds. Here is the result. Actually it looks great but is very brittle. Can disintegrate due to easiest handling. On the picture the cast item is at the top left corner. The patterns are in the middle.

Looking again at the stern of this ship I found I do not like the false handrail posts I did so far by carving them out of wood. Besides carving three hundred of posts is crazy. This is not a work for sane person. As I looked at how nicely the parts can be copied with making a pattern, making mould and then multiplying it by casting I figured out that I am on wrong path. Here is new stern false handrail pattern. I carved it myself from wood. I will make 300 of these by casting Epoxy Putty into moulds.
