CSS H. L. Hunley

 

The CSS H. L. Hunley, a Confederate submarine, made history on 17 February 1864 when it became the first submarine to sink an enemy ship, the USS Housatonic, in Charleston, SC, harbour. The boat was designed and built in 1863 in Mobile, AL, CSA, and named for the principal investor in the project. In 1864 it was shipped by rail to Charleston and taken over by the confederate army. The Hunley carried a crew of seven or eight, one Skipper and the rest to hand crank the propeller. The sub was 12 Meters in length with a beam of 1.17 Meters and a hull height of 1.2 Meters. It had a top speed of 7.4 Km/hr. Not only was the interior very cramped for the crew, but the two hatches were only 40 cm in diameter, making entry difficult as well. Hunley’s armament was a spar torpedo, a copper canister containing 41 Kg of black powder explosive mounted on the end of a 6.7 Meter spar. The torpedo was equipped with a barbed spike designed to be rammed into the hull of an enemy ship below the water line. The Hunley would then be backed away and the torpedo detonated by withdrawing a cord attached to the fuse. Unfortunately for the crew, the torpedo seems to have exploded within a few meters of the sub and sank both the target and the Hunley.

This model is based, in part, on the reproduction of the Hunley on display at the Charleston Museum, which I saw in 2001 on a visit to South Carolina. I first modelled the Hunley in SketchUp in 2014.

The Whitworth 12 Pounder Gun

The Whitworth 12 Pounder was designed and manufactured in England by Joseph Whitworth in the mid-nineteenth century. The gun’s design was unusual for field artillery of that period: it was breech loaded and had hexagonal rifling, which gave it a high degree of accuracy and a range of up to six miles. The barrel was 7’ 9” (2.36 M) long; the gun weighed 896 lbs. (406.4 Kg) and was manned by a crew of six.

After being rejected by the British army due to cost, it was purchased by the Confederate army in the U.S. civil war. It was also used by the Union Army, particularly at the battle of Gettysburg.

Canon de 65mm Mle. 1906

 The French mountain gun designed by Col. Ducrest and manufactured by Schneider was a specialized infantry support weapon. It was very small with a weight of 400 kg (882 lbs) and an height of 1.25 m (49 in) and easily transported by four mules over difficult terrain. The gun had a range of 5.5 km (3.4 mi) and a rate of up to 15 rounds per minute. It was used extensively by the French army mountain troops during WW I and was sold or donated to several countries between the world wars.

 French 75 Sight

A week ago I posted my model of the French 75 gun. In the write-up I mentioned that most of the photos of the gun that I found were lacking the sight so I left it out of the model. Then I found a YouTube video about Matthew Switlik and his 30-year effort to own the gun: https://www.youtube.com/watch?v=JDz0uW2jex0&t=983s. In it there’s quite a lot of discussion of the sight. He also mentions drawings of the 1901 sight that I found on the internet.

 The sight (site in French), made mostly in brass, incorporated collimator optics, which are still in use today in some gun sights. The sight was mounted on the left end of the gun’s trunnion, the pivot point for the barrel assembly, and had its own small shield to protect the gunner.

French 75 Gun

In 1898 the French army adopted a revolutionary new piece of field artillery, the Matériel de 75mm Mle 1897 or as it came to be called in English, the French 75. The gun is considered to be the first modern artillery piece because of its rapid firing system. It used a hydro-pneumatic recoil absorbing mechanism that allowed the crew of six to fire the gun repeatedly at a target without re-aiming after every shot. By the end of WWI, about 12,000 had been produced and were in use by many different armies including the British and Americans.

The gun in this model is the 1901 version. The model is based primarily on museum photos. There are some missing pieces in the model due to the fact that they are not in most of the available pictures:  the telescopic sight and two leather pouches on the back side of the shield. This is my second effort modelling this gun.

The Little Grey Fergie Restoration Project

 From Wikipedia

 “The Ferguson TE20 (Tractor, England 20 Horse Power) is an agricultural tractor designed by Harry Ferguson. By far his most successful design, it was manufactured from 1946 until 1956, and was commonly known as the Little Grey Fergie. It marked a major advance in tractor design, distinguished by lightweight, small size, manoeuvrability and versatility. The TE20 popularised Harry Ferguson's invention of the hydraulic three-point hitch system around the world, and the system quickly became an international standard for tractors of all makes and sizes that has remained to this day. The tractor played a large part in introducing widespread mechanised agriculture. In many parts of the world the TE20 was the first tractor to be affordable to the average farmer and was small and light enough to replace the draft horse and manual labour. Many TE20s remain in regular use in farming and other work and the model is also a popular collector's item for enthusiasts today.”

The Fergie is 2.921 m (9’ 7”) long, 1.625 m (5’ 4”) wide and 1.320 m (4’ 8”) high.
