Firemodeler1 Posted April 20 Report Share Posted April 20 A new project is now on the workbench. Started in on a 1/25 scale M-20 prime mover. Evergreen stock and brass or various sizes and shapes will be used to create the model. Biggest challenge will be the Hercules Diesel engine that will have to be done. There are some decent sources of information out there including Tankograd and a walkaround by Dave Doyle publications. The molds for making 10 12:00 x 20 tires are now done. The tires in the photo are 3D printed that are being used as masters. Will post pics as progress continues. Link to comment Share on other sites More sharing options...

Firemodeler1 Posted May 1 Author Report Share Posted May 1 Got a small update on progress. Tires and wheels have been cast and work has commenced on the suspension. The rear suspension consists of active springs, torsion rods and two floating axles. The springs are made of strip brass, soldered together at the ends starting with the shortest first. The torsion rods are made of brass tubing. With those done front springs and the front axle will be next. After that the cab will be worked on. One door is done including the brass hinges. The cab itself will take some additional alteration before the doors can be hung. Link to comment Share on other sites More sharing options...
Firemodeler1 Posted May 5 Author Report Share Posted May 5 Here's a look at all of the parts that make up the front and rear springs and axles. They are ready for mounting on the chassis. The universal joints are 3D printed from Down Range Productions. They sort of snap together and are easily modified for the driveshafts. The odd thing in the right front is a template for drilling the lug nut holes in the wheels. Each one has 10 lugs so getting even spacing is a bit difficult. A paper template of 10 segments was drawn to scale and taped to a piece of brass sheet. The center hole was drilled first and then the 10 lug nut holes were drilled out afterward. The center plastic piece fits into the center of each wheel which gives the template a positive location for the lug nuts. Link to comment Share on other sites More sharing options...
Firemodeler1 Posted Thursday at 02:46 PM Author Report Share Posted Thursday at 02:46 PM Got the front end put together finally. Little adjustments here and there to make it the correct track. Tie rod and steering is also done. The wheels are held on to the axles with small bolts and washers. inside the axle tubing is a piece of plastic rod that was drilled out for the bolts. The wheels spin freely on the brass bushings inside each wheel. Link to comment Share on other sites More sharing options...
