Do you think this mold will duplicate a 82 rear bumper?

This is nice, you can make custom bumpers with a taller spoiler like the Vanacor version that I have ... If you make the bumpers with good material like US Composite sells then you should have no problem making better bumpers than most of the vendors sell... Ecklers quality is good, Vanacors as well but that Lingenfelter POS that I got for my C6 was horrible...
Why not make one or two bumpers and see if there's a market ?? Or make them to order ...

I think he also has a 80-82 front bumper mold to, if he does I am going to buy that as well.

It looks like a pretty good mold inside, he says it was made in the early 80's so maybe it was made from a un-distorted bumper.

Basically my urethane cover tore during a mishap and I really would like a glass rear bumper. But vendors want a arm and a leg for these covers so thought I would make my own then sell the mold to someone who wants to make one.
 
My 74 needs a new rear bumper. Something custom w/taller spoiler
would be nice. :wink:
 
I would certainly be interested in a front bumper mold if you're going to pick that up. Personally, I think the dovetail on the factory rears is about the right height. Actually, if anything, I wish the back didn't slope down so much so that the spoiler could be the same height but without as much angle. But then again, I have a vision in my head that I don't know if I could recreate in the real world.
 
Well, I got the mold today, it is a very strong well made mold. Think is what I am going to do with it is make 2 bumpers for my 82 and then sell the mold or loan it out. Apparently it has never been used and was made according to the seller back in the early 80's.

Anyone interested in renting the mold? Or buying it?

I would be willing to to let anyone in souther california, nevada, arizona use it as long as you return it.

This is the person I bought the mold from. However he says he didn't make it and doesn't know who did. Could this be a corvette vendors mold? Or does it look just custom made? It is an extremely sturdy mold and weighs a good 50lbs. It doesn't appear it has ever been used since all bolts that secure the two sections are rusted solid.

This is the guy/company I bought the mold from

My layman's eye says that was made either by a shop intending on mass production or an individual with dreams of becoming a shop. It looks well done from the pictures you posted. Not just some one-off thing someone put together in his back yard.
 
jusr curious if making carbon fiber bumpers with this mold would be a coool idea or is fiberglass a better choice?
 
I think it would be awesome. Carbon fiber would look great on a black car but I've seen many carbon fiber parts that turn yellow due to UV exposure... not sure if a good clearcoat would fix this....
Fiberglass bumpers are quiet heavy but I think that's mainly because they're very thick.
My opinion: it looks cool but if somebody wants a leightweight bumper he can just buy a urethane bumper...

Other than white glass strands, vs black 'carbon fiber' , what EVER that is,

WHAT is the difference between these to types of construction....still have resin in it, no? same resin??

Epoxy is epoxy - yes. But the advantage goes to CF with its higher Modulus and therefore in addition to its better strength to weight - you get improved stiffness to weight.
Another means of keeping the weights down on 'glass bumpers - take a tip from boatbuilding. Foam Core. You can up the overall stiffness and keep the weight down by using a foam core in your laminate.
Here I'm laying Balsacore inside my Eckler's flip front (before my return to AD - note Hair and ear ring!]:

Yes, a coating of epoxy is required to beat the yellowing you see on CF parts left to UV.
CF is NOT cheap - and there are BLACK Fiberglass profucts that can give the appearence of CF without the physical propertys - or cost. But there is always the CF decal approach too - and they won't yellow.

I would be interested in any tips you can give on laying up FG. Also, one of the things I want to do on my hood is leave a small portion exposed for a CF look. I was thinking some simple black fabric dye on FG cloth and then resin over would give the desired look. Would that work?
I have done several projects with FG so far and have gone from being completely lame to kind of half-assed being able to accomplish what I want. But for what I would like to do with my car I would really like to be able to do a job I would be proud to show off. The other thing I would like help with is any tips on working on body panels still mounted on the car. Going to do some fender vents and such but I'm not prepared to remove the fenders.
