The Peacemaker

The Ripsaw's body is of a mid-70's Chrysler Valiant Charger stretched and modified to fit over the tank chassis. Leftover Cessna sections are bolted up front, the grille is filled with bullet 'teeth'. There is a hole in the roof which allows for The Bullet Farmer to to sit atop and operate the searchlight. There is also space for his two henchmen in the back. The driver of the vehicle sits in the engine bay of the Valiant Charger shell. The driver had to be buried deep inside the vehicle which made it very difficult to see anything except straight ahead. The tracks had to be covered to protect the driver from the sand and dirt.

Originally the Ripsaw came with a watercooled Merlin V8 engine. Upon arriving in Australia the vehicle was tested on a 1km track, but the engine overheated and the brakes caught on fire. The exhaust pipes were 6 inches long which made the engine extremely loud even with hearing protection on

Two radiators were installed in parallel either side of the motor so the water only flowed through the radiator with the least resistance. Proper exhaust system was installed in Villawood. Additionally single cooling fans and computer cooling fans were installed on the the transmission cooler.

The movie's main mechanic - Mark McKinley - tackled the braking system. As it turned out the brakes gave 100lb of pressure all the time which made the vehicle take off 'like a boat', but the reason they initially caught on fire was a 10k ohm potentiometer on the steering wheel and the brakes pedal.

Eventually he tamed the beast with adjustable pressure valves in the hydraulic lines so it would not drag its brakes any more. Not only the brakes were rewired but the air filters were replaced and additional 3rd radiator was installed in the back.

During testing in Broken Hill the vehicle was not responsive enough and it also swallowed a lot of sand. Due to dirt getting past the air filters the engine was damaged and cylinders had to be re-honed. Also during testing the track guild wheel was lost which went into the track and bent the differential. After replacing the wheel, straightening the differential and removing the track assemblies the team discovered that they were half welded only the exposed sections. That issue had to be fixed at Alexandria.

After testing the vehicle was shipped to Namibia where the engine was again replaced. The Merlin V8 swallowed a lot of sand and it had to be replaced with a smaller 502 Chevrolet engine. An electric water pump was installed, Ford Falcon's single core radiators and Falcon double fans as well as EWS water pump fan controller. A secondary battery was added along with Anderson plug. The vehicle was fitted with new tracks which only lasted a month before they broke. The cost of tracks was estimated at USD 18,000.00. A special diesel bath was made to try and keep the salt out of the tracks.

Hi Colin you are most welcome, just a bit to do all I can do is try and see what happens.

Hi I've been cutting even more off as you can see, I'm going my version of the "Peacemaker Mk2" if I may, I'm fitting the engine in the front as normal and I'm going to have to make my own tracks

I've cut out the lower rear window panel most of the boot plus fuel tank, shortend the rear light panels, narrowed the floor pans, removed parcel shelf, cut the off the front chassis rails to put in a 25mm section.

Hi Peter.

I'm really glad you're going forward with this build. Will be following with interest.

Great research. I'm in awe of the mechanics and designers who worked on this movie.

This is a behind the scenes of the cars...Maybe you saw this already.

Hi Pete

Nice to see this one on the blocks. Interesting conversion job. We don't see many auto builds on here, mostly because they aren't military. Some of the disciplines are slightly different so could be an interesting journey. Good work on the body and wings so far....

As an aside, in my rare forays into auto modelling I have stripped the chrome parts using household bleach and repainted using alclad, but they were when I was trying for a pristine concours finish. I assume this one will be getting a more world weary finish so the bright chrome doesn't impact so much....

Cheers

Tim
