The casting of the body has actually not occurred to me, a semi-clear resin body would have been perfect for this project. Sadly, the work put down on the existing barrel is looking at me with huge puppy eyes, begging me to keep it as is. But I do think I should start looking into resin casting for future projects, might save me some time and open up new possibilities at the same time.
If I understand you correctlythen yes, I am currently experimenting with electrical tubing, did not know about the aquarium detail though, yet another thing I believe I should look up.
Right now the barrel is getting a rebuild using transparent electrical tubing, that part is going a bit slow since I already have an existing barrel and that makes it a lower priority compared to the rest of the tank.
