I am planning to cast a resin mould, think of it as a curved tube.

Question is - its going to be tricky to do the casting in one pour due to the way the part sits - would it be possible to pour the casting in seperate stages, so that inbetween each pour I can move the part to an upright position?

Will the fresh casting resin bond to already cured/part cured resin?

Any other suggestions of how to pour a curved tube?

Thanks in advance
