Seriously if the doors don t fit right before you cut the roof off a car i can assure you that they won t fit after you weld it back on and the results could be permanent.
How to chop a roof.
Thats at a competent shop with out paint just the chop in primer.
I havent seen many chop top beetles that actualy look good only a few that do.
Use a scale drawing to figure out the pitch of the roof using the scale drawing we then measure in from the wall plate side towards the centre a total of 12 inches in this case using our scale which is 1cm 1 foot.
We then make a mark at the 1cm point and then measure directly up at 90 until we hit the roof.
Since the angle will be different now cut slits along the edge of deck lid opening.
Use a tape measure to measure the entire width of your building.
A birdsmouth cut has 2 parts.
A quick glimpse of the chop taking shape.
Thats a risky thing to do.
This will allow you to push down the lip to meet the correct angle.
Measure the width of your building.
Make sure the doors line up properly before starting or they might just be worse when you finish.

I heard it was because the person doing the chop ran a continous bead on the sheet metal creating hot spots and warping the panel.
The rest of the body will just fold outwardly if not held together properly.
As you can see from the cut tack our roof actually went up about a inch.
The roof is a major structural point of the vehicle once the roof is off.
Before you start cutting you first need to determine how long your roof rafters need to be and the angles at which you ll cut the top and bottom of the rafter.
With that said let s get this chop started by showing the subject in its formal self.
A horizontal cut called the seat cut and a vertical cut called a shoulder cut.
For a shop at least 2 000 3 000.
The deck lid piece is next.
And one with that many compound curves it is a very complicated things to do.
