I think a prop safety loop is an excellent idea I saw an american guys locost blog a while ago and he had made a 2 piece loop from something like 3mm x 30mm strip.
Definatley could save damage to the car and your legs if the prop let go.
Am guessing the prop would just fall into the loop like a crude bearing if it snapped and help stop the prop whipping around.

Do you need at least 2 for it to be worthwhile? Could see that if it broke you would have both the diff and the engine ends spinning when rolling.

i plan on putting the safety hoop just forward of the TT6 uprights as this then creates quite a good cage around the prop using the TT6 & TT4 uprights as additional structures to stop the prop coming thru the tunnel into the cockpit.

10 Points Andy,bloody good idea 100% no cost too,if you are really concerned why not beef up that part of the tranny tunnel with a cross brace and a sheet of ally near the joint. I think I will do it now as that's where I am welding in now.

cheers Paul,
its not very often i have a good idea but this is one that might be of use to others.
i can,t put any more braces into the tranny tunnel as i have fitted the floor now, but this safety hoop is defo going in.

that is a really good safety feature you are talking about
Jonneturbo lost his car to a fire when the prop failed and ripped out his
fuel lines in the tunnel

cheers Les, credit should go to Londonsean69 for the idea in the first place, i,ve just taken it on & found a locost solution,
hope it is of use to others too.
i,m only using thin ali for my tunnel sides so any extra protection from a failing prop is welcomed, its even better knowing that it was free,
i mean after all i HAVE to keep my reputation for being a tight git

cheers

Think I may be doing the same...
Just read this on LCB

"Another propshaft failure
Not mine,on a Seven that Dave Walker had on his rollers, went through the side panels and hit his leg at 120mph On page 98 in this months PPC.
That does it for me, definitely going to reinforce the tunnel."

wow, that sounds nasty, i haven,t read the article so hope the guy is ok.
strange how this thread has discussed the very possibility of that happening, scary thought

lets hope it doesn,t happen to anyone else.

cheers
