Jack 18" Hunslet 1898 Locomotive in 7/8ths Live Steam.

Part 3

Here are some of the frame 3D renderings showing Jack progress. A lot of the parts will be laser cut to save time and get the project moving. Once the CNC mill is complete the majority of the parts will be done using the mill. I have no issue machining a lot of parts by hand and have not mastered turning both axis simultaneously to get smooth arcs and curves. Thus it is easier to have parts laser cut. The frames are produced in mild steel along with the deck and motion parts. The spacers are brass bar stock. All parts shown in orange are bearing bronze. I will also post some photos of the cast parts I purchased from Brian Wilson as they are stunningly beautifull and will make a superb finishing touch to the loco.

In the gallery below are the first laser run parts I picked up this previous week. I am really looking forward to getting the project moving and will be focusing all my spare time on both the "Jack" locomotive and my DHR B engines. It is time to get these finished.

Jack 18" Hunslet 1898 Locomotive in 7/8ths Live Steam.

History:

The Hunslet Engine Company of Jack Lane, Hunslet, Leeds is a locomotive-builder.

The first Hunslet engine built for export was their No. 10, an 0-4-0ST shipped via Hull and Rotterdam to Java. Remarkably, the last industrial steam engine built in Britain was also built at Hunslet in 1971 and also for export to Java. This engine later returned to Britain and is preserved in working order. A large number of short wheelbase tank locomotives (0-6-0) were supplied to the Manchester Ship Canal Company and one of these (No.686 of 1898 'St. John') still survives on the Severn Valley Railway and is still in regular use as a 'Thomas The Tank Engine' lookalike.

The engine is this build is #684, class 0-4-0 with a wheel gauge of 18".

The build is based off of Brain Wilson's design which is shared on the yahoo group: http://groups.yahoo.com/group/Steammodelloco16mm/. I have made some minor modifications to my files, most of which were to make the loco more flexible as far as function and maintenance. Below is a gallery of plans and information I could find on Jack. The engine will be a 7/8ths scale live steamer running on 32mm track.
