Bow Ties (USA-spec Side Marker Lights)

Yes I've wondered about that too. If the edges were straight would it still fit the body shape? Should try and make a small stiff cardboard replica and see

 

In-period review of US GT4 shows them straighter but not perfectly straight...

Have not seen the bucket type on GTS or GTB, they have the flat surface mount type which don't exhibit this feature.

 

don't say bow tie too loud or the chevy people might come asking for a royalty check!

 

If someone could loan me a side marker bezel with straight sides, I could use it as a pattern to make a mold & return it.
Making a mold does not affect the original in any way.

My reproductions would be a fibreglass reinforced polyurethane that is quite rigid and only begins to soften at 280 F.

Currently my workload is pretty light so I'd only need it for a couple of weeks more or less.

If you can help with this, please send eMAIL.

 

you gonna try and straighten them out or just for copies?

 

I am hoping to borrow ones that are already straight, or were straightened by their owner.

 

Since the period pic proves, that these were not straight from factory, this would be a perfect application for design of a 3D-CAD model and then print the pattern.
Am original sample would be still necessary though.

Verell,
do you meanwhile use 3D-design and print techniques?

I routinely use 3D CAD and have used 3D printing where part strength & surface finish is not important. 3D printing is useful where you are making a 1-off part such as a mold pattern where you can afford to invest a significant amount of time filling, sanding, & polishing/texturing the surface to get the correct finish.

I've been closely following the evolution of 3D printing since the mid '90s as my son's best friend's father works for Sanders one of the pioneering companies.

 

Verell,

I hope you can do this. Mine are pretty unsightly. I trust someone will provide a good one for the mold. If I had one it'd already be on its way to you!

Jack.

 

If @Verell sees this it might rekindle his interest in doing a test with 3D printing.

 

Definitely interested. if you could share 3E cad files.

3D Cad technology continues to evolve very rapidly I am currently awaiting a 4th 3D resin printed part to make a 4 cavity mold for KLIPPAN seat belt buckle covers. Resin printed parts have very good finish & dimensional accuracy, and are not porous. Unfortunately the resins ae not strong enough for actual use. BUT they are more than adequate to use as mold patterns.
