Resin Model Making

One word - "difficult"!!!!

2 words - VERY difficult!

Here it is, docked beside my Eaglemoss starship:





I've always loved the shape of the starships in the Trek movies and have a fondness for the Grissom. The only way I could get a decent sized model of this, was from "Warp 2." Thsi was my first ever resin build. It took a long while to sand and file away at the mould joints, to make smooth. Thsi involved many hours of work, for only a relativley small area. I was using a file and sandpaper to rub.

I did as much pre-gluing as possible before spray painting. I used a can of primer from the pound store. This took 3 coats! I then used Tamiya spray "flat white" - 2 cans, which is loads more than a much larger plastic model kit, like the Reliant, and then clear gloss. I then used normal Tamiya flat paint in the pots to colour the various gull parts.

By far, teh bit I was dreading was the assembly of the warp pylons from the saucer section onto the secondary hull. I did this by turnign teh model upside down and using some wood blocks to support everything as perpindicular as possible. This was not easy. I did not like using the superglue either, as "strings" formed which were difficult to get rid of. I felt rushed into gettign everything stuck in place. After 24hrs, it cured. Alas, there was a slight sag. :( However, when photographed and displayed from above, oiit looks good!

The decals were really easy to apply. (Phew!).


Alas, the model did not come with a display stand. I had some spare oak skirting board wood, so cut that, and wood stained it dark brown. I used an old shower head holder and screwed it into the wood, as I needed a semi-circular shape to hold the round secondary hull.

In summary, I would tackel another resin model, but I woudl need to think carefully about it, such that it would not have complicated glue joints, like warp engine pylons! Maybe a steamrunner class.

My questions to you guys on how to improve:

1. Shoudl I have drilled a hole in the secondary saucer to insert a brass rod etc to hold it? Is drilling resin easy, and could I use a normal hand electric drill, or is it a pillar drill job?
2. Can you buy display model stands anywhere?
3. How do you "sand" the superglue, to make flat? It was very porus, so I put pvu glue over it to cover the holes.....

Any other tips on resin?


Finally, voila, it's place in the collection:

 
Heck, I've been building resin kits so long, I don't even notice the difference any more.

I don't know why you had to use so much paint. It's usually the same as any plastic kit - a coat of primer and then the final color. Did you wash the model before painting? Resin kits usually still have mold release lubricant on them. That would result in paint not sticking.

Pinning parts together is often a good idea. Resin drills easily. I just use a pin vise. It's mostly necessary when gluing large load-bearing parts.

Sanding and grinding: wear a dust mask. You get resin dust in your lungs, it's there for life.

As for the glue stringing, well, just be more careful. :)

Stands: A bunch of folks make a variety of them. Here are some at SSM:

Search around the web, there are certainly more. Though I usually just get a wooden plaque at the craft store, stain it, and jam an acrylic rod in it.

Do resin kits have better detail than they used to? I remember some early ones having detail so bad, one good coat of primer wiped it out.
 
Oh heavens to Betsy yes. it's a fine art now. A lot of garage kitters are even having their masters done in 3D and grown on a 3D printer.
 
I'm glad they contained teh instructions to wear a face mask (I wouldn't have, otherwise!). Good thing they included that line on HSE in the instructions!

I thought the detail on the model was really good. This one had fairly simple lines on it, e.g. the concentric circles on the saucer. These were fairly deep, at aorund .8mm ish. I washed the model with warm soapy water, as per the instructions, but it was a nightmare to spray over! No idea why it used up so much paint.

If I get a resin model again, I will try to drill and pin i. I presumed the material would be very brittle, hence my hesitation. Shame there wasn't any excess for me to pracice on.

The links to teh display stand website is appreciated - thanks Forbin.
 
The difficulty of drilling resin depends on the resin. There are all manner of different flavors of the stuff and some are harder or softer than others. Mostly shouldn't be a problem, though.

Also, what is a "pillar drill?" Is that the same thing as what we in the states call a "drill press?" If so, that would make matters simpler. Especially for large parts.

Nice looking model, by the way.

I think the resin that most garage kitters use today is flexible and easy to drill without breaking. In the dark old days there was brittle, hard resin. A British company called Warp tended to use hard, brittle resin mixed with microballoons as an extender (like hamburger helper, to save on resin). It made the kits so brittle, I actually shattered the wing of a Babylon 5 Whitestar just unpacking it. Things are much better now.

As for how good resin kits are these days, Industria Mechanika is one of the top casters:

Fantastic Plastic sells general sci fi kits and has pictures of the parts:

As does Federation Models (with a much more extensive catalog!)
www.federatiomodels.com

I'm sure quality varies, but the most recent resin kits have detail comparable or superior to the best plastic kits.
