Which pillars are which?Abc???
 
After reading the thread on chopping a top I want to make sure I understand which pillars are which.

Pillar A is the front windshield
pillar B is the door pillars
pillar C is the rear section correct?

Measurements to be

A: 3.75
B: 3
C: 3.99

I just used what the guy said to do I hope these cuts work

That part is correct.

Those dimensions may or may not be correct,
depending on how they were measured.

A is always the front windshield and then just count back from there.

Thank you guys for confirming the pillars
and about the measurements I wanted a 3 inch chop and I just used the formula the guy did in the main chop measurment thread

A : 3 x 1.25 =3.75
B : 3
C : 3 x 1.33 =3.99

I don't understand where these measurements and the 1.25 or 1.33 factors derive from. If you want a 3-inch chop, lay out 3 inches horizontally, it will change length with each pillar. It might end up the same as the ones you listed, may not. The key is to lay out your chop using horizontal measurements, not distance down the pillar. Obviously the more angled the pillar, the longer the distance is. If you change the angles of the pillars it add another bit of complexity.

If you want a wedge chop, then you need to do more calculations. Remember it is a lot easier to cut a bit more off than it is to add it back on.

What 38 chevy said ...

I used a wide strip, the size of the chop I wanted, and laid it alongside the body .... that way I didn't need to know how far along each pillar I needed to measure ... 4 vertical inches ... projected sideways ... is still 4 inches vertically ...

It's the clever ones that understand the geometry ... me ?? nope ...

Just check out the rest of the info about pillar widths to save yourself some heartache.... http://z13.invisionfree.com/VolksRod...post&p=1474336

Just cut it and lower it to where you like it, level it out how you want and fill it the pieces. Thats too much math for me.
