Fiberglass repairs and bonding

[IH2LOSE]

So 67 heaven was kind enought to share some of his hoods dimentions with me,and I think I can graft the top hood skin of a 67 big block hood on to my 62 including the spear down the center. I have it pictured in my head now I just have to be able to make it work. I am hoping I can mark along the edge of my hood in about 3" all the way around (just before hitting the 2 spears going down the outside edges of my 62 hood)and then remove the entire center section.then section the same center section out of 67 hood skin the same way and then bound it into place some how.Then some how shape a spear onto the front header panel.I will also have to remove the rear over hang on the 67 hood so I can retain my cowl vent.It seems I will also have to some how bend the front section of the 67 hood by cutting shallow slices in the underside of the hood skin because of the roundness of the c1 body style. any free advice is greatly appreceated on this one.

Hey Larry,
I think I would sketch this out on a piece of paper to be sure you are going to like the effect. Sometimes it looks different on paper than it does in your head. I am sure, with your ability you will be able to blend the two elements together. I would just want to be sure you will be happy with the results.

Thank You!

But what I am missing is the knowledge for the ability and thats what I was looking for.I just ordered a book on fiberglass repair I hope to find the knowledge I need in there.

I am commited to this hood style on my car,Now I just have to figure out how to deliver the goods.This one for sure is going to be an exspencive attempt so it HAS to work.

Thanks again when are you painting

Larry,

If you haven't worked with fiberglass/resin/etc. before, you'll be surprised how easy it comes. In many ways I prefer it to working with metal.

All that cutting and splicing is going to come back to haunt you after you paint the car. You are going to get some movement in the glass when it gets hot in the sun. You would be much better off making a mockup of the hood skin the way you want it and then make a mold from that. Then layup a new hood skin all in one piece. You can bond the new skin to the frame and have a perfect hood. It sounds like a lot of work, and it is. But to build a hood the way you are talking about and then have it look not come out right is much worse.

The sanding and the grinding I have NO problem with. Years and years ago I worked at a body shop and my job as the aprentance was to do the dirty stuff.That was paint stripping,grinding the cracks on the fiberglass cars, But I never paid attention how he did his repairs. I do remember having to grind the area again when he was done to remove paint sticks he used to screw into the back or the front of the repair to hold things in place.

I was told that the frame man made the most money in the shop and thats who I spent as much time with as I could to learn that how to pull a frame.

Today I am in the heating and a/c field and I used to spend alot of time in the attics with the fiberglass insulation so I have become imune to fiberglass making me itchy.

My concern is how to bond things together. When a fender is attached to a another part there is a bonding strip.(in metal repair we would say we "fish plated it)

But in a crack repair your just removing the bad material and then mixing up resin and some glass and putting it in the crack to repair it ( in metal repair we would call this a butt weld)

Now in a hole repair You ar using the matt to cover the entire hole along with some broken up matting (in metal repair this would be a lap joint)


So with this hood project I am just wondering from a exsperianced glass guy what is the preffered way to do it. It seems my only option is to due a butt weld style repair ( because the engine side of the hood has to look as good as the top side of the hood) and I am just hoping it will be strong enough to live on the hood that opens and slams closed.

Thanks again every one I will keep you guys posted on the outcome of this project as soon as I get my new hood skin.

I have an entire new 67 big block hood skin coming.this is the skin that if you ordered a new press molded hood this is the part that would come bonded onto the 67 hood frame. I asked the manufacturor just to sell me the top skin to save on the exspence of an entire hood and the trouble of trying to seperate it from the hood frame.

Do you think I should just bond that skin onto my 62 frame.I thought it was better to keep with the original 62 outer edges that all ready match up to the fenders and cowl and header panel perfectly and to just section it into the the hood.

I do know I could have gotten a bond on 67 hood scoop (yep they are still available) but I wanted to have the center spear also so when some one looks at it they wonder how that happened

 

[Thumper]

I have a feeling that once the skin shows up and you can lay the two next to each other, a lot of your questions will probably be answered. It's hard to know exactly what you need to do until you have all the parts laying in front of you.

Good luck. :bang :bang :bang

I'm wondering if it would just be possible to lay the '62 hood skin over top of the '67 hood skin and mark off the dimensions that you need to make the '67 hood fit and than cut it just slightly oversized to allow for the sanding at the edges for a proper fit.
I'm sure this idea sounds too easy to actually work but since you know I'm an idiot when it comes to doing any work on these cars myself I don't know any better than to come up with dumb ideas
The spear shape on the nose of the car in front of the hood would have to be shaped either by hand or by a homemade mold i guess.

Larry,
I will hopefully be painting in a few weeks. After installing my hood on the car for the first time I was not happy with the fit especially at the front nose, so I have put allot of effort into getting a good fit on that. Also I just finished painting my house, raking the leaves in the yard (lots of trees around) and taking my daughter to look at $$$ colleges $$$. Just not enough time.

I would try to bond the new skin to the old frame first. The skins are pretty flexable and it may just work. The C1 hood has a curve to it and the midyear is almost flat but I would try it. If you would like my advise you can call me at my shop. 203 888 4018. It is much easer to talk to you than to try typing it out on here. I have a few different ways of doing what you want. I have been doing body work on vettes as long as I can remember. I have a few good ways to do your hood. Call me if you want. 8am to 430pm mon -fri. I am in Conn. Ask for Brian.

Thanks I will take you up on the offer and contact you today.
