After many years vac-bagging and avoiding infusion I was tempted to try it after some gentle persuasion.  Freakin' awesome!  Not hard and great results.  Yay!

However, I recently made a booboo.  Infusing a 1.2m x 0.2m part; 4x200g with 6x200g in places; peel ply, mesh, bag.  I opened the inlet clamp and it seemed to stick.  A little jiggle and the resin shot through, not all the way but a good chunk was done in about 20 sec.  Bugger!  Let it flow at a more sensible rate to finish up.  I let a little more flow in on completion but as expected its pinhole-tastic on the fast bit.  Is there any contingency for things like this, ie should I have let more resin flow through or is it a once the damage is done thats it?

If there's a fix it would be good to have a list of problems and solutions.

Some good advice from Hanaldo thereSmile
As said if you over tighten the clamps they can stick. You may be surprised how little pressure is required to form a seal. If you over tighten you can deform the tube, even when you release the clamp resin doesn't flow so you open it a bit more then woooosh the resin shoots through.
If your workshop is cold, less than 25 degrees then pre heating the mould before infusion helps with the resin flow. This will increase the infusion rate so bare that in mind. 
As said everyone develops there own unique methods. Infusion does require a degree of skill and feel to get perfect resultsSmile
