Roof Chop Legalities?
I have just started playing with my first roof chop and I need some legality advice from the experts. the car came pre-chopped (started anyway) and
the windscreen height is just perfect, but the pillars have been straight cut, and I have heard a rumour that aus engineers only certify a Z cut. is
this so? can anyone recomment an outer east melburnian engineer to have a chat too?
cheers

Frank Fordham is VASS engineering a chop on a car I am working on at the moment.
Basically, Yes you need to have a stepped cut. There are a lot of other factors including wiper sweep area and vision height that you have to work
within as well. You won't get a heap of information unless you are prepared to proceed with the whole job. An engineer charges between $400 for a
simpler job like this to $1000's for more complex and involved unique jobs.

thats cool, The vision isnt an issue, it is only a 2.5" chop and i have checked, 11m infront and 10deg up is easy. it will definitely be a long term
project, I was hoping to do all the cutting and sheetmetal welding, then tack the pillars/structure in place so that I could just get an expert to
come along and seam everything as i had heard that thisw as the most cost effective and viable method.
Ringwood East is nice and close so I will drop by tomorrow.
Thanks.

50mm will be good, as I have had passed. The preferable way is to have inner plates also, with plug welds to the outer sections of the pillars. Any
inner support frames up in and around the roof area that have to be cut if necessary, will need a cover plate with 45 degree ends. All makes more
sense and quicker if you see one in the flesh that in the process of being done, or if you can get someone to draw it all down. But like I said, you
pay for peoples time in regards to some of these things, as there is quite often a lot of time invested in getting it correct.

hmm, 50mm. no way i can drop the roof that far, will have to find out if it is possible to put enough extra support inside the pillar to make the
current straight cut viable, otherwise I will have to transfer onto the rustier 2 door shell.

from memory what you are proposing is called a wind deflector and is not considered a windscreen / windshield.
wind deflectors don't have to have wipers whereas a windscreen does.
It's been a while since I've looked at the local rules so things may have changed
Best you readup up the state regs.
Cheers
