1973 Mercury Montego GT

[gks1964]

I've been work in partnership with Tim Stevens for about the last 6 months on trying to build a master of this car. Well we think it's done. The 76 Montego went on the back burner for this project.

That's my hope!!

You going to make the molds and do it all? That will be cool.

Quick mock up with all the parts in place!

[gks1964]

Got 7 of the 8 molds made  and samples cast. Tim did an outstanding job with the rear bumper and valance. Now to do the major mold of the body!

[DoctorLarry]

Gerald, are you pressure casting these?

[gks1964]

Yes Sir!! At 40 psi!!

I need to build a pot to do that in. Did you vacuum the mold rubber first?

I pressurize the rubber before I pour it and then pressurize the molds for 6 hour cure time.

Very cool, one of my favorite stock cars and street car too.

Little rivet counting for you, the hood is incorrect. The center has a peak and the scoops are too short and narrow.

I think you are correct on both points!!

I'm not a caster, I just may be confused, but I thought rubber was gassed in a vacuum pot, and as you said, resin is pressurized.

Air pressure can also be used to force  air out of the rubber. The reason I pressurize the mold while it curing is to force the rubber on to the master to pick the details. The resin is force into the mold with air pressure to also remove air that cause voids in the casting.

Hope is understandable.

Progress we got a mold!

Isn't this a '72? I thought the '73 had the energy absorbing front bumper(?)

It has the big bumper. It’s been narrowed as they did on race cars

[yellowsportwagon]

To be honest the only sheetmetal forward of the doors that will interchange between 72-73 is the hood. And even then the latch is different. The grille and headlight doors are different too. The 73 frt end was much flatter to match the huge frt bumper.

Shows what I know about racing, I guess....
