Chariots of Fire

That is BIG water for sure! They will need industrial size mains and in line pumpers to supply those behemoths!😵

I was going to ask about the double pump panels. Just MHO but I think the single one looks better and is more prototypical. Nice job putting the two bodies together to form the tandem axle version. Most difficult part of that is hiding the joint between the two pieces!

I got the windshield wipers done today. Here are a couple of photos that show the finished wipers and how they were made. Here is the beginning. Four long common pins are used to make two wipers. First cut each of the heads off the four pins. Then bend the ends of two of the pins slightly and grind a flat surface on the outside of the bend. Lay them flat like you see above. Then, with a torch and a very small piece of fine solder connect the straight and bent pieces together. They should like this when you are finished. The angled piece is bent to form the part that will be inserted into the cowl. You have to be sure and bend them in opposite directions because one is for the left side and one is for the right side. Note that the wiper on the right has a slight curve to it. This one would be for a curved windshield. The straight one will work fine on a flat windshield. At this point it sort of becomes a trial and error project of deciding how long you want the blades and at what angle the bend has to be made. That part is left to the particular project and how the wipers fit against the windshield. You want them to lay flat and at the same time they have to fit the angle of the holes that are drilled in the cowl. Nothing like a bit of practice. The finished product looks like this. For each wiper I added a small hex bead to hold the wiper arm up slightly from the cowl and to add a bit of detail. Some modern wipers are black and not chromed like these. The blacking can be done with a magic marker before the wipers are mounted. Paint tends to rub off whereas the magic marker is more permanent. The blade length can be adjusted to some extent depending on the individual application. I think they are superior to the kit blades that tend to be very clunky looking or that are molded into the plastic.

Got a bit more done on the cab. Little things have cropped up to show that I need to pay attention to the process. The vent windows of the cab were a bit of a chore since I had to install the windshield and dashboard before the interior tub could be set. I should have done those vents first as it would have been easier to get my clumsy fingers inside the cab. Plan ahead, as they say! Other things have been completed as well. I used a Zoet liquid chrome pen to do the turn signals, siren and door handles. Same type of thing as Molotow but I think the results are better. The engine has been started from the castings of the IH Scout 345 V-8. The rear view mirrors came from the parts box. In the photo the drivers side mirror looks cockeyed but it really isn't. Must be the camera angle. Looks like I need to ckean up the paint line on the running board too! Whew! I'm getting rusty! The paint has polished out nicely, however. It dried quickly and with some Novus 2 it shines. Next is to get the windshield wipers done. I'll do a quick how-to on them since I use common pins and some hex nuts on the installation.

Hmmm! Interesting. I will post again. I made a few additions since the past post. I was able to see the former pic but these show progress to date. I've painted the cab, hood and inner tub. Color is Ford light blue and is engine paint. But I like the color. I used Molotow chrome on the hood ornament and the headlight buckets. The blue stripes on the seats are decals printed on the ALPS. I used a chisel point magic marker for the windshield gasket. Nice straight lines. The windshield fits tight against this gasket thanks to the way Dave Natale was able to cast the cab from the master. Wheels and axles are mounted on the frame. A look from the side. The international decal on the hood side was also printed on the ALPS. Previously for two other IH builds I found some nice images on line and had also photographed one closeup that I could copy into a graphics program for printing. The door handles will also be chromed but not until close to the end of the build just to keep my fingers from messing them up. The body will be painted the same color blue. Planning on a light bar for the top of the cab and a combo red light/siren for the top of the left front fender.

The wheels and tires are now set. They just need the center caps but will wait until the last to put them on in case the wheels have to come off for any reason. The cab and body are about the right stance. Will be taking a short break on this build while the temperatures are in the 20's here. The basement area where my workbench is located cools off enough to make it uncomfortable. On to armchair modeling for a bit!🥶

Here's hoping that the orange of the Ford cab does not bleed through the yellow you are proposing. Be sure to use a good barrier first. Perhaps it is not as much a possibility as it is with red bleed through. Keep up posted!

No need to do that. You could coat the mold but then each of the castings would have to be well washed before painting.

Warren: I'm using Mann Ease Release 200. You can purchase it through Amazon. A bit less than at M-M. It works well for me, either rubber to resin or rubber to rubber. It's recommended to spray once, let it set and then spray again before pouring the last rubber.

Welcome to the MC Forum! Lots to see here that will be of interest and informative for you.

No holes, but I do pour resin on the top part so completely cover it. Once in a while I will get a small bubble of trapped air but if it is not in an important or incomplete cast I usually ignore it. The casting resin I use is also from Micro-mark and is the CR-300 rapid cure resin. They also make a 600 resin but it takes much longer to cure.

The mold results are in. Now it will be back to the frame, get some springs and set the location of the cab on the frame. The tire mold is complete and the wheel mold is setting up. I use communion cups for the casting resin. You only need small amounts for most parts so they are ideal. You can see in the photo below that very little flash is around the tire. Here's the mold for the engine from the IH Scout. It fits well with the Loadstar. Tires and wheels are now done. Here's a look at what I'm after. The ALF body is about the right height but the Loadstar cab needs to drop down. IT's not 4WH drive so it should sit lower on the frame. Right now there are just temporary pieces of plastic holding it up. The tires that were cast are painted with Tamiya TS-82 rubber black. Best stuff yet that I have found for getting that rubbery look. Thinking of a companion piece for this Reo Gold Comet color wise.

I use the spray that Micro-Mark sells.

Hi, Warren. No, the only mold release needed is between the second and last pour. The master comes away from the mold without any issues. The second pour adheres to the first one as it should. Will post some new photos in the next session.

The mold is almost ready for the second pour. The base mold rubber is setting up. In this photo is the cast resin tire that I added the straight tread pattern to. Beside it is one of the rear tires. The masking tape inside the front wheel will trap the mold rubber underneath. The second pour has been completed. Note that the mold rubber is brought to the top of the tire. There is a little bit of spillover onto the sidewall in one place but after the rubber is cured, that can be cut away. Trying to clean it before the rubbers sets only makes a mess. To the right is the front wheel set in the second pour. It is brought up to but not over the outside flange. When both of these are fully cured two things need to be done. First is to cut some notches in the edges of the rubber. The purpose is to provide some points of alignment for the two mold halves once they are finished. Second is to spray the entire inside of the mold box including the master with mold release. If this is not done the top rubber mold will stick to the bottom one and the master will be sealed inside. It's hard to see but the center of the tire is free of rubber for most of its depth. This will also provide alignment and eliminate a lot of the flash that you see on kit tires or the two halves not being centered all around.

Just a tip for doing the DODGE lettering on the hood. Before painting cover the letters with Bare Metal Foil. Trim it close to the outside of the letters but don't bother going in between. Then do your usual painting. After the final coat, use a Q tip and thinner and gently remove the paint on the top of the letters. Just dampen the Q tip. You don't want the thinner running onto the other painted surfaces. Tailgate letters might need to be done with decals. here's what it looks like on a '66 W-300.

Next up is to get the molds made for the tires and wheels. I cut some cardboard into pieces large enough to leave a 1/4" gap between the tire and inside face of the mold box. Same for the wheel. The pieces are put together using a hot glue gun and a mark was made inside the tire mold box where I want the first pour to go. A wheel mold needs three pours of mold rubber. The first is to fill the bottom of the box up to the line and let it cure. The next pour will include the wheel. The wheel master is inserted into the box after a thin layer of mold rubber is poured on top of the first pour. The rubber needs to coat the bottom surface of the tire completely and sit flat on the mold rubber. Very carefully pour the rest of the liquid rubber around the tire master on the outside only. Do this a little at a time, keeping the tire securely in place so this pour does not get inside the center hole of the tire. Weight it down with a paint bottle or similar weight until this second pour is cured. The second pour is continued until it just rises to the top of the tire but does not spill over onto the sidewall. Once this is done let it cure completely. The mold boxes are ready for the first pour. Note the marks on the two plastic cups. The mold rubber is mixed in 1:1 parts A and B. I mark one cup, insert it inside the second cup to mark it taking into account the thickness of the cup bottom. Use the lines on the cups as a guide for equal amounts of each. The first pours are done and need to cure. When that is done the second pour for the tire and wheel can be done. For the wheel I'll cast it face down. I cut out a circle of masking tape and put it inside the back of the wheel. This will keep the mold rubber from filling the inside of the wheel when it is put into the mold. The tape will be taken out after the second pour is cured.

Got a few photos of the materials that I will use in this build. Although it will take on the look of the Chevy pumper, I'm using one of Dave Carey's IH Loadstar cabs and an AMT/Ertl ALF pumper body to start. The IH cab is one piece except for the hood. Included are the floorboard, dash, inside door panels, steering wheel and column, seats and running boards. The ALF body sides are well defined and will go nicely, however the pump panel is going to be made shorter. The long wheelbase doesn't quite cut it. I'll also use the ALF frame although the Ford snowplow frame or even one of the Ertl International frames would work also. This truck is not a big one and I have chosen 37" tall tires and spoke wheels. Years ago I had a tire made and cast of the right size but it has a mud/snow tread design. They are ok for the rear but a standard road tread is best suited for the front unless the idea is to make the rig all wheel drive. In that case the M/S tread is good for the front as well. I chose to put one of the rear tires in my lathe and turn the tread pattern down. To get it back to the right diameter I added a strip of 0.020 by 0.250 plastic strip stock to the tread area. Then I cut grooves in the plastic while it was still on the lathe. Not perfect but the idea is there. Now I will have to make a mold and cast two front tires and also a couple of front rims. I only have one right now and that will be the master for getting two more. The mold making and casting process will be part of this build. The front tire is on the left, a blank rear in the center and the proposed rear rims on the right. The front rim will be cast separate from the tire. More to come.

HI, Dom. I have done much of the same as you; utilizing kit parts as masters. Warning lights and bezels are not that hard to do if you have a good source for the master. The Trumpeter ALF kit has numerous bezels and lenses that can be used that way. Also check for things like the light bar that was with the Jeep Honcho kit. I think there were lenses for the lights. Even the 1/32 scale Monogram Mack CF kits can be used to effect. If you have an extra one you might be able to cut out the tail light bezels and cast them as well as the headlights, although the latter would be small for 1/25 scale use. Lenses are easy to cast once you have a good master to copy. I have clear casting resin that mixes 1:1 parts A and B. It's made by Teexpert. Got it on Amazon. The mold material comes from Micro-Mark and is the 1:1 Rapid Cure rubber that they sell. It's not cheap but it picks up every detail nicely. The clear resin seems to stay clear but it takes 24-48 hours to set completely. Simple molds can be made by gluing the master to a flat piece of plastic or card stock and then building a wall around it with similar material. You need to use mold release also so that the resin that you pour in does not stick to the mold. This only works for a part that does not have an under cut. If it does a two part mold may be the better choice. Tires and engine parts are some of the things I have done with both a flat surface mold and a two part mold. I will include a how-to as part of this build.

Got some pics taken of some of the parts that I'm collecting for the build. Will post one or two as soon as I can. Have some front tires to make up for it first.

I'll include that, Brian. There's plenty of treadplate on the back of the rig. Not all has to be foil but for some areas it is perfect.

Do it with a series of drills. Small at the center and then build out. The final opening can be done with a rat tail file.

I have a new project in mind that is based on a simple Chevy C70 fire engine that is not far from home. But I'm going to substitute an International Loadstar cab that Dave Carey cast. The idea behind this project is to make it a "how to" using basic techniques and tools. The emphasis will be on clean building, careful alignment and scale. If any of you that do occasional scratch or kit bash work have any ideas you want explored please feel free to speak up. There will be no brass work in this build. Strictly plastic and a bit of resin. Here is the real truck that I will be basing the project on.

DonMillsHobbies also still has them although they may not be plated. But a Molotow pen would take care of that.

"Slime" green; probably the most difficult color to keep clean and looking good. Was quite a fad back in the day with some"experts' saying it was for better visibility. Today lots of rigs are back to some scheme of black over red, white over red or just plain red but with lights and strobes everywhere! And thrown in for good measure are diagonal reflective yellow stripes all over the back.☺️
