Hello all, I have made a mould for my telescope tube  (300mm dia x 1500mm) using the Uni-Mould system and it has suffered from slight distortion (slightly off circular on one side).  I cannot post cure the mould as I dont have an oven big enough.  I have clamped the mould back onto the pattern.  Is there anyway I can reinforce it to hold it in shape?  I was thinking bands between the flange bolts.  Maybe two layers of 5mm pvc foam strips with a couple of layers of carbon/epoxy?

Any suggestions welcome.
