Welcome to Librarium Online!
I recently got a Hellcannon, and I can't put the barrel together. It's curved, so I can't put it together without there being a gap on the opposite side. Has anyone had this problem with their cannon? I don't want to Green Stuff it because Green Stuff's expensive and I need to save some for my other guys. I can't really think of any other ways to solve the gap problem, and I can't really put much of the model together without the cannon being fixed. If I have to, I'll use some Green Stuff but as I said, it's pretty expensive and I've recently pooled pretty much all of my money into my Warriors army. I'm running out of cash and want to spend it on models, not green stuff.
I had the same problem as you and I did not find any other solution than green stuff . I think it initially was a sort of plumber putty so you might be able to find a cheaper alternative.
Thanks for that. Does plumber putty set hard like the way Green Stuff does? I was thinking of using Blu-Tac, but it never sets.
Greenstuff can be pricey but if it will help a model look better, that you've already paid $50+ for, to me the cost is negligible over the lifetime of the model. If you take care when transporting your Hellcannon, you'll still have it around in 50 years and every year you'll wish you'd put it together right.
Try to find some GF9 greenstuff, it comes in two huge separate tubes and will last you quite a long time without hardening, plus it's much cheaper than Games Workshop's if you're looking at cost/volume.
The unfortunate problem with casting large metal pieces is that they WILL warp after cooling. Your best best is definitely green-stuff or something similar.
If you go to your local hardware store and ask for a quick-set compound (just explain it to someone there, they should help) you can find some reasonably priced stuff. Just be aware that most compounds set a LOT faster than green-stuff. Many are 5-minutes or less.
I have never used the GF9 equivalent, but mostly because I think their quality is poor compared to other manufacturers. I stick to PP, GW or Armory. For the money, GS is actually pretty good stuff. Once you get the hang of working with it you can do almost anything with it. Any metal model will most likely require some GS at one point.
Honestly, as much as I know you hate to spend money on not-models, green-stuff should last you quite some time (I've been using the same package for over 6 months now, including a Hellcannon and many other metal models that require a lot of gs.) The hellcannon will probably require less than a 1/4" slice of GS, which leaves you with 6-7 inches left to use for future projects.
Good luck with the Hellcannon. I am halfway done painting mine and have to say it is fast becoming the most challenging project to date, but also the most fun and probably most rewarding.
Try milliput, it is much cheaper than green stuff and it gives you quite some time to work it.
Thanks for the advice. It turns out I also couldn't be bothered to wait to buy something else, so I used some of my green stuff at home. I used quite a bit but I still have a heap left.
I spent a half an hour with a dremmel on the sides that ran under that rail on the top. once I ground that 'banana' bend off, it fit together well. not seamless, but within reasonable tolerances.
