Hi All,

At first, I assumed this ramp plastic was normal, but the more I looked at it it just doesn't seem right so I checked IPDB and it appears that my ramp is warped.

Don't understand why as there's no lamps under or nearby.

It the left ramp from a Gottlieb System 3 Gladiators.

I can post better more detailed pics if anyone thinks it will help.

The left hand side is.......sort of curled over to the left more, right hand side on picture, not vertical as I'd like it to be.

It also appears that Gottlieb at the time painted the outside of the ramps in silver and I'm not sure how to tackle this correctly without wrecking/removing any paint.

You can see the warp where the plug and look is hanging over.

Any help/advice much appreciated.

You will have to create some sort of jig and put it into the oven at the lowest setting.

I'd just heat it with a heat gun and bend it as you need to.

Without a jig, you risk deforming it in undesirable ways.

thanks for the prompt replies......but yes I did consider a length of timber as a support/brace and held in place with plastic clamps, but which side to put the support on?

If I put it on the outside, I run the risk of possibly due to my error, ruining the inside that is seen if it goes pear shaped.
If I put it on the inside, I run the risk of ruining the silver paint that you see from the inside.
I don't have any other ramps to practice on.

Yep I'm a pessimist but thinking realistically.

My concern with using the oven is that the ramp may distort elsewhere there isn't a jig.

Still open to more suggestions, or tell me "this is what you do".

Does it really effect the ball, or is this just cosmetic? If cosmetic, I would just leave it alone.

i never played the game believe it or not.

was missing numerous parts of both lower flipper assemblies but it powered up......then straight into tear down.

i did think of leaving it alone as once any damage is done there's no going back.
