I have an old 6,3 swallow tail Dave Mac and Im about to give it a new lease of life and fix a few old dings and compressions.
Has anyone converted a thruster into a quad? Did it work?
Its a single into double concave and Ive seen a few quads like this but generally with more concave in the rear between the fins.
Cheers 
Cool, I will give it a shot maybe this weekend if Im not mowing the lawn or weeding 
Cheers Chris and Dave 
Yea I am going to give it a crack Ted, I will take some pics as I do it.
We have just had a death in the family so I will have to start it next weekend 
Jeepers. Well lets hope u get some fun pits at fav wave of mine down there. Would be interested to know if the vegetation has grown back any since xmas. Take some pics of it if you get the chance
try simon anderson's facebook page there is a bit of info on him converting a thruster to a quad but making the back fins closer together to give more of a thruster feel rather than the twin/quad feel
cheers
Thoughts are with ya mate. My grandad left us on monday arvo. Happen to be in the room when he took his last breath. Sad . Champion bloke, champion footy player in his day. RIP mate.
