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.

Re: My new mill

Always nice to have some new equipment in the home shop as encouragement to move on with projects. A friend installed a new Bridgeport in his home shop, just like this application in the corner where it looked good and seemed to fit well. Once he began to machine some long parts at extreme travel of...

Re: How does one polish a thread?

Just recently a friend handed me a paper bag and instructed me to read the book inside at least twice before returning it. When I pulled the book out of the brown paper bag, here was a copy of the Moore book. It has taken me to a different level of how I look at precision surfaces on any machine too...

Re: Starting a thread on the lathe with a die

Recently I had to cut a 12-32 thread to a shoulder but did not want the starting groove of an upside down threading tool. Solution was to cut about an 80 percent thread almost to the shoulder going very slowly to insure a safe stop situation.I then used a special guide in the tailstock drill chuck t...

Re: Valve gear parts for big boy

At one time, Barry Hauge of Superscale used to offer the zerk fittings as part of his line of detail parts. I forget the reason he stopped offering them, perhaps there was not much interest in them at the time. I should have bought more of them when he had them offered.

Re: The Drill Press Whirlygig

Great story of the lathe build not long before I became aware of Greg Lewis and his lathe project. No others at the school had bothered to mention the drill press mishap. One morning in class, the Sand Crab instructor, introduced Professor Lewis to our class and explained that he was in the process ...

Re: Milk of Magnesia as Anti-Sieze?

Just a few weeks ago I had the assignment of taking apart a King sander valve from a Baldwin locomotive constructed in 1925. The three bolts that secured the cover to the body of the valve, all had a white colored residue on the threads. I believe that someone may have used small amounts of white le...

Re: Simple lubrication question...

As long as the pump bore is super smooth, an O-ring should last a long time. BEWARE of oil on the ram. Even though it seems like a good idea to lubricate the ram, lubrication can easily make it past the O-ring and become part of the boiler feedwater. Here is where it gets real ugly. I saw a guy who ...
