Getting Limber




Limbers are like the pick-up trucks with a tow hitch of the Civil War.  They were used to haul cannons, caissons, battery wagons, and even a coffee wagon.  We have several period photos showing rows of limbers and other carriages lined up at wharves and railroad depots as in the scene above at City Point, VA.

I had perviously made cannons using cast metal, laser cut wood, and photo etched brass parts. I ordered some 3D printed limbers to go with the cannons from a vendor in Europe. Unfortunately, when those parts arrived, they were not printed at the correct scale. They were about 20 percent too big. Trying to redress the problem with an overseas vendor was not practical. So I still needed some.

A few months ago, Gerry Dykstra, from the ACWRRHS Group,  sent me a copy of the 3D print file he drew for a battery wagon. Each artillery battery had one battery wagon along with a battery forge and 4 to 6 guns . 

It was a simple matter to scale the file to 1/48th and print on my 3D printer. The model is very nicely done. But, he did not include a limber. He did include a limber pole, an iron rod used to support the tongue of the wagon when the limber was not attached.  However, I believed I needed a limber to accompany it and my artillery pieces.

I decided to draw one myself. It is not that complicated a vehicle and it would be good practice for me in Fusion 360. Gerry already drew the wheels, so it was fairly simple. See the second  drawing.

I printed a test model. It need just a few modifications and it was good to go.  Then I printed  7 more.  

I decided to not include the ammo chest handles in the print. I will add those with wire. But I did include the locating holes to simplify drilling the holes.

This was a fun project that didn't take too long. Now, with limbers taken care of, I need to make the supply wagons. I started making a supply wagon using my cast wheels and laser cut parts. But I think a 3D printed version would be better able to show the detail on the wagons such as the tiny rivets and bolts.
