Jack 7/8ths Live Steamer [ Part 3 ]

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.
