Slant Chop

Guys,

I'm finally getting close to chopping my '35 (the sheetmetal phase is closer to the end than the beginning)-I'm reasonably comfortable with a regular Chop (2"), but I would really like to do a 3" front and a 2" rear chop-does anyone out there have any "hands-on" experience doing this?

The reason for the hesitation is that I can understand the front and rear chop, it's the in-between that gets me-I could probably work my way through this, but I am looking for as little stress as possible as this will be my first chop-I'm comfortable with cutting and welding sheetmetal.

I've heard of using a chalk line and other ideas. Any experience out there?

if the post's are str8 up and down then you just need to incorporate the correct angle into the cuts.

What kind of car? Sedan? Coupe? Ford? chev?
Post some side shot pics and I'm sure you'll get some good info.
The center post and quarter glass areas are going to need some special attention along with the windshield posts/A-pillars. Bob

You really need to study up on this before you take the saw to it. Do a search right here by clicking on search and putting in chopping the top, search the whole site. There are a bunch of project cars with lots of photos like this one..click here

There is an interesting article here..click here Click on the links at "Chopping the top on a 1941 Ford Coupe".

Something simple like a 36 Ford pickup, you can almost do the "chalk line" but you wouldn't. It just doesn't work like that. Click here

Here is a coupe..sorry there was no link to the story but I am sure you can find it over at Metalshapers.org, that is where the photos were found.




PLAN, PLAN, PLAN, that is the trick.

Brian

Like MartinSr said plan ahead! I chopped my '34 five window
3 1/4". Your '35 is a little rounder than a 34. So it will be a little more difficult. Is it a five window?
This is just a thought. Measure the top front to back,cut a sturdy piece of something thin with that length at the taper that you want to be transfered onto the body.
On the 34 the horizonal cut out of the back window was only about an inch long then I dropped straight down to about an inch above the body line and followed that line to the quarter windows. The quarter windows were cut the same way horizonal until past the body revel then just matched the cut above the body line. The top piece slid down behind the bottom and then got scribed for cutting. I didn't have to mess with the compond curve of the roof doin' it that way. I don't know if that will work on the 35 being that it is more curved.
I have some pics. If you want to see them email me yekoms@comcast.net and I'll get them to you . I'll try to download them and get them posted later also.
Have fun,Smokey

Thank you everybody for the Posts, I was away from the Computer this weekend (working on the Car you know)-

AS far as answering the questions, here goes-

-baddbob, it is a 5 Window Coupe-I have purchased the Tex Smith Book "How to Chop tops"-I've read it front to back, and have a bunch of Street Rodder articles about how to chop-not scared (well, kind of) of a regular chop (pretty straight forward it looks), but the mating of the front and rear sections concern me.

MARTINSR-thank you VERY MUCH for all of the time you put into that post! The articles were enlightening, your advise insightful. I could not get the Metalshapers' Article to come up, but looking at the picture, it shows yet another way to cut the top-so far, I've seen about 6 different places and ways to cut to fit.

yekoms-thanks for the great idea-I had thought of marking a 3" mark on the front "A" pillars, then a 2" mark at the rear window, and then stretching either a chalk line or a 1/8" vinyl tape (like the pinstripe, 3M kind) around the top, through the "B" pillars to the front-problem is, the cut around the back of the top, getting it straight, and hoping that the tape (or chalk line) would be at the correct distances-your idea is thought provoking.

Sounds like you did your Chop kinda like Marcel DeLay and Sons did in an Article in Street Rodder on a 3 Window '36-I like this idea because there is less chance for distortion and metal match up. I would love to see your pictures (always looking for good ideas)!

Guys, after thinking about it for weeks, again the problem appears to me to be at the rear of the quarter windows and mating of the two top pieces (getting the angles right). After cutting the Top off (gulp!), cutting the Top into front and rear sections and the resulting cuts, I could put the front Top back on, aligning the front Windshield Glass (really the swing out Windshield), which would put the back part of the front Top (as it has to be lengthened) at the wrong angle, pie cut the Top so that the front and rear parts would line up, and then deal with "B" and "C" Pillars-not sure if this is the way to go, there just doesn't seem to be many (or any) Articles on Slant Chopping-

This is something to think about. I have never seen a slanted front to rear chop done, even in a magazine article. But when slant chops are done with a bigger cut in the rear the rear window is usually slanted forward. I would think that may be something to consider for the front windshield. You would actually have to slant the windshield forward in your case to bring the back of the front top up to the angle of the rear top. I don't know what that would do to the proportions of the look of your five window. I also don't know what pie cutting the front top would do to the proportions as well. When you say pie cut the front of the top do you mean a long pie cut along the top of the doors and then fill in that opening with metal? Or do you mean a small pie cut behind the header and slant the top from there? What I think you will have to do is take some pics of your car from the side and the back and the front and make a bunch of copies. Make sure to put a ruler in the shot so you can know the actual scale of your pics. Then cut your pics up using the scale in the pics. This will give you a better idea of what you are going to be dealing with. It will also give you a better idea of what it will look like after finished. Make sure you keep all the pieces you cut from the A and B pillars and the pieces from around the rear side windows as you may be able to use them when you need to lengthen the door tops. Have you considered slanting the B posts forward as this may help you get better proportions.

home brew,

Thanks for the ideas-you are bringing up things that I hadn't considered-with the pie cut, sorry, I didn't explain it properly. What I was thinking is attaching the front of the Top so that the Windshield Posts lined up properly (everything I have read says to worry about the Glass first), then pie cutting from the bottom of the "A" Pillar across the Header for, say, 8" or so, aligning the front and rear tops and filling in the middle, and then filling in the "pie".

I have considered slanting the "B" Pillar forward-it does look good-jury's out on that while I think about it .

I purchased a complete Top (from the belt line up) off of Ebay (even drove to San Diego to get it ). It's out getting Star Blasted right now, so I will definitely have enough pieces.

I am beginning to think I would be better just chopping the Top in a regular fashion-I have put too much work into this (just this far) to end up with a car that's out of proportion. I will keep on this hunt, however, because I have a few weeks of final Metal work before I'm ready to Chop. Thanks again, I appreciate all of the angles you guys are throwing at me-

Don't give up on the slant top chop. I have seen many coupes done this way and they look great. As with anything the more work you put into something the better it looks. I think in this case you will be rewarded. One good thing you have going for you is you are going into this with lots of research and knowledge behind you. Good luck!
