king derelict Posted January 26, 2023 Share #1 Posted January 26, 2023 In an effort to maintain my last unbroken New Years resolution (finish all started projects). I completed an experiment with the 1/700 Hobby Boss HMS Astute. I have a few submarine models and it always puzzles me to find a good way to display them. I have also been impressed by modellers who have encased their finished project in resin. I wanted to try it but had no real idea about how to build a casting tank, the right resin, release agents, does the curing heat damage the model or the decals etc. So this is less about building Astute and more about trying to set in an epoxy sea. The Hobby Boss kit has few parts and the submarine has a simple black paint scheme. The decals are a bit of a challenge with lots of long thing bands to place on the hull The casting tank is made of 1/8 Perspex and held together and sealed with hot glue (first mistake). I sprayed the inside of the tank with Future polish as a release agent The plan was to present the model on the surface so the craft sticks, double sided tape and Lego bricks set the sub at the right depth in the tank The project was going to sit on the brand new dryer while the resin cured. It seemed a good idea to put the tank in an extra container - just in case. There was a bit more resin than I expected in the first pour but I put it all in and was not terribly happy to find that the tank had a leak on one of the sides. - but I was thrilled that I had decided to use an extra container and I decided to carry on. Then winter hit Florida for a week and I didn't want to try the second pour in case it didn't cure properly. I resumed with a different brand of resin and made three further pours to get the depth I wanted. They all cured nicely The leaked resin peeled off the bottom of the casting easily The sides of the tank released with a bit of force and the basic casting seems to be successful with a couple of caveats. The long delay between first and second pours resulted in a definite interface between the two pours. Also the second resin has a slight tan cast to it. I had planned to try to colour the resin but couldn't think of a way to get a consistent colour. It belatedly occurs to me that I should have coloured one part of the two part mix which would then be used in all the pours. There are small bubbles - I'm not sure how to improve that I added some waves and wakes with artists gloss medium but it wasn't very visible against the clear resin so I added some medium with micro balloons added. I think it was a bit too much and its stark against the clear resin So i added a sea blue base which has got closer to the effect I wanted Far from perfect but it answered some basic questions for me and I'm happy with a first attempt. I have a part built 1/700 USS Gato for the next part of the project - full immersion. I have a couple of Flyhawk U boats that I would like to make up into a single display with one surfaced and one submerged. They are much too nice to pour resin over until I know what I'm doing, Thanks for looking in.

Old Collingwood Posted January 26, 2023 Share #2 Posted January 26, 2023 (edited) Thats a toough job to pull off Alan as i know it falls to the security of the case (as I read in other resin ship/sub dio's) as you know I have my Flyhawk Hood on hold that I plan to make her in the sinking role dio.

Landlubber Mike Posted January 26, 2023 Share #3 Posted January 26, 2023 Alan, that came out really well! I've always wondered how to do the resin pour approach like you did, so thank you for posting the process. I have a couple of models in mind for a similar approach. I forget exactly, but from others online, I think the bubbles might be caused by too fast a pour, or it might be from the heat as the resin dries. In any case, adding a little color to the resin might minimize their appearance, if not look more natural. Great job!

OC. I think your Hood diorama will be great. It's worth practicing with your chosen resin before committing to the main task. I found a half inch layer cured no problem. A few stray bubbles aren't going to be an issue with all the mayhem of the sinking. Alan mtaylor, Canute and Old Collingwood 3 Quote Link to comment Share on other sites More sharing options...

I also probably stirred the mix too fast. It's a bit scary committing your finished model to the resin but for some displays it's a great look. I have a handful of 1/700 submarines that I want to use this technique for Alan Old Collingwood, yvesvidal, Landlubber Mike and 1 other 4 Quote Link to comment Share on other sites More sharing options...
Landlubber Mike Posted January 26, 2023 Share #6 Posted January 26, 2023 You're a brave man for sure for trying it. Can result in disaster if you're not careful. I saw one guy's diorama almost get ruined because he poured more than recommended, and things just got messy. Looking forward to seeing your next attempt! mtaylor, Old Collingwood and Canute 3 Quote Mike Current Wooden builds: Amati/Victory Pegasus MS Charles W.
