Re: Hydrostatic Lubricator

I work at a local museum where the steam supply valves for most of the appliances come off of the big turret housing. Best to be sure of the seating of the steam supply valve for the lubricator to insure it does not leak when refilling the lubricator with steam oil. I am now including an additional ...

Re: D valves not seating - how do I fix?

Often times I have seen D valve equipped models and other D type valve equipped steam appliances that either have too much wear, corrosion of the cast iron seating surface or if new, tool marks from the teeth of the milling cutter used to cut the valve surface. In all cases even the small void like ...

Re: VERTICAL TURRETT LATHE (CNC)? NO WAY

I often use a 42 inch Bullard at the railroad museum where I work several days a week. The large parts from the 9.5 inch Westinghouse air pumps are very heavy which precludes easy setup on a regular engine lathe. The big VTL is government surplus and has seen little use during its long life. Each ti...

Re: How to gate and runner a car frame?

Have you tried a thin coating of powdered graphite in the mold to speed the flow of the molten aluminum to all parts of the casting?

Re: Pre heating boiler water

I have seen a large 15 inch gauge steamer that was being operated at a 3 day meet. Each evening, the owner placed a custom made thick reflective insulated jacket over the boiler from the back of the stack to the front of the cab. Looked like a big silver blanket when installed. He claimed it kept th...

Re: Pre heating boiler water

In the days of steam, the railroads had house steam boilers and connections inside the roundhouse and outdoors on the garden tracks. The locomotives that needed to be kept hot without a fire had the steam pipe connected to the monkeytail on the steam dome to keep the boiler warm. Was also a good way...

Re: Pre heating boiler water

Long ago in an issue of Live Steam Magazine from the 1973-1974 era, there was an article by a builder of a Little Engines 1.5 pacific. Seems he used an Atlantic boiler with an extended smokebox to fit the Pacific frame. He put a serious coiled feedwater heater in the monster long smokebox and had go...

Re: 1-1/2" Scale Sunbeam Headlamps

Jack, Now that is one sweet addition to an already wonderful headlamp. Sure makes those of us who appreciate detail salivate all over the computer keyboard. Such improvements also bring up the question of could the older versions of your headlamp be upgraded to the new gold standard? My headlamp fee...

Re: brass tubing

I spend many hours each week working with full size steam locomotives. More than once I have been called upon to machine bronze fittings that are then silver brazed on the end of the copper tubing to complete the new steam line. Have yet to see threads on the copper tubing in full size steam locomot...

Re: Brass 1/8" Scale Retainer Valve

Very well done with the brass version of the retainer valve.

This may encourage me to develop the wasp exclusion device which was very popular out west where any small diameter hole was a prime residence for certain varieties of wasps.

Re: 1/8" Scale Retaining Valve

I went to the Shapeways website and put in an order for two of the retainer valves in cast brass. The next day I got a notice from Shapeways in regards to a problem with the part design which only the person making the drawing could resolve. Therefore, my order was canceled until the part design pro...

Re: 1/8" Scale Retaining Valve

Thank you so much for your efforts. I have wanted a few of those for many years and had almost finished an oversize master for lost wax casting. Now I can relax and order from Shapeways.

You have helped to fill a serious detail void in our hobby.
