Re: A Real Dirty Job

Wolfgang thank you for the latest reply pointing out the weakness of the existing eye beam design. Yes, I am aware that the intersection of the eye and the beam in both the drawbar and the safety bar represents a stress raiser and a fatigue point if there is not a generous transition radius between ...

Re: Fiddle Fidd.. Fi...e

The water inlet fitting installed on the pump body. The pump body had to be drilled and tapped first before the inlet fitting was made. It looks quite large as good engineering dictates that the inlet piping to the water pump (the pump suction side piping) has to be made larger than the pump dischar...

Re: Fiddle Fidd.. Fi...e

All of the steam side fittings made and installed. Still more work on the water side fittings to make. It may look simple but there was a lot of very concentrated and tense machine work involved. Like drilling a 1-1/4" long hole with a #52 drill. On the first attempt, the drill seized and snapped of...

Fiddle Fidd.. Fi...e

About a weeks' work in the shop. The lubricator for the LBSC steam operated duplex water pump in 1/2" scale. An untouched photo before final cleanup. First described by LBSC, in the Model Engineer, in the fall of 1928. Still completely relevant today. Reproduced in his book Shop, Shed and Road. You ...

Re: A Real Dirty Job

Most rotary table work done here to date is on the 6" dia. News (pre Yuasa) horizontal rotary table. It is fine for 3/4 " scale locomotives. But like everything, the add-ons or extra's made over the years make it much more useful. Probably there are 15 centre plugs of different diameters made for di...

Re: A Real Dirty Job

Carrying on to make two relatively simple parts, the engine/tender drawbar and the safety bar. One is just a straight dog bone but the other has a 5/16" offset in it which makes things interesting. I probably have by now a total of seven different types of sheet metal, tube, pipe and mild steel stri...

Re: Mission Impossible - Designing and Constructing a 3/4" Scale Westinghouse Cross Compound Air Compressor

Hello Asteamhead, I think that you know much more about building these miniature air compressors than I do. I am good at finding or looking up information but Richard is the one who can start with a blank sheet of paper and come up with something completely new which has never been done before. Yes,...

Re: Mission Impossible - Designing and Constructing a 3/4" Scale Westinghouse Cross Compound Air Compressor

Since I like to delve into the history of everything, I believe that all of the original castings and all of the original machining on these Westinghouse cross compounds were done by Stoney Burke in Australia in the mid 1970's. That is all I know and if anyone knows anything more, please chime in.

Mission Impossible - Designing and Constructing a 3/4" Scale Westinghouse Cross Compound Air Compressor

Not only to design and to build it but to make it a working, practical and reliable unit. Richard is the one who is doing all of the thinking and development work associated with this for the 3/4" scale Big Boy. But first we have to have a unit that is both working and reliable in any scale. So, we ...

Re: A Real Dirty Job

The heart shaped rocker assemblies Installed and working. The were a couple of issues related to the rocker assemblies installation on the engine as I had to slightly file down the trailing truck king pin to give it about a 0.002" clearance so the pin would freely slide down into and mate the traili...
