Re: Jet Vertical mill a clone of a Bridgeport?

Completed repairs to the 28 year old Jet vertical milling machine. All of the varidrive bearings were either showing signs of distress or ready to begin making noise. All bearings of the varidrive unit were replaced along with the drive belt which was almost wore out. Found many bits of the belt spr...

Re: ww2

Long ago I worked in a shop that had several machine tools of different manufacture, all with the special plate calling out a war production finish. Mostly paint on cast iron with little or no filler to smooth the castings. One big Pratt-Whitney lathe was most interesting. It did not have the war pr...

Re: Self-ejecting chuck keys Y/N

I had a chuck in a school setting that came equipped without a spring on the chuck key. Was only a day or two before it was left in the chuck and the green button pushed. Next thing was an airborne chuck wench and a well educated student. Same thing happened the next day in a different class. This t...

Re: Piston Ring Drag

Many times in this hobby, well intended tight clearances end up giving trouble. The locomotive or water pump will work just fine on air. As soon as steam is used to operate the locomotive or water pump, the performance goes downhill fast and often times stalling out is the end result. In one case of...

Re: Cab interior

Cab interior colors could vary between railroads and steam and diesel locomotives. Even the caboose interior colors could vary from road to road. Baldwin for many years supplied their catalog locomotives with a medium green with a slight yellow cast for many years. The ATSF used a darker green which...

Recently I was assigned the task of developing a custom sized lapping plate of 1 inch thick, 1.875 in width and 6 inches in length. The lapping plate has the specific end purpose to lap the D valve surface in the steam head casting of a full size Westinghouse single cylinder 9.5 inch diameter air pu...

Re: Question about bearings

Long ago I was constructing the deluxe RRSC arch bar trucks for a tender. The journal box castings were to be bored out about .010 to .015 larger than the OD of the bearing according to the set of prints. I bored the journal boxes deeper and adjusted the axle for the use of two bearings on each end ...

Re: 482 night run

Quite the show of how coal burners can cause trackside fires so easily. That sort of spark event is exactly the reason why the UP Big Boy tenders were equipped with the special water spray device on the rear of the tender. A spray was emitted from the nozzle on the back of the tender that would keep...

Re: Stiff throttle on Allen Mogul

Last several years I have gone through more full size globe valves and injectors on full size locomotives than I can count. First thing I discovered is that the guys who worked on the valves before me often compromised various elements of their rebuild. I have found wire reinforced packing that ate ...

Re: GP MU Plugs

I saw the same ad on Discover Live Steam website. The seller was definitely RR Supply with a listing of New Hampshire as their location. Apparently the few that were listed have been sold and the listing was removed. Might be possible to sent a message to the Discover Live Steam website owner and se...

Re: New York Central Streamlined Hudson

Jack, Great work as always. What sort of clear coat material are you using for all of the custom castle nuts? I have been tasked with the construction of a Bruno Platzer 2.5 scale Butterfly fire door casting set. Will need to make a pair of custom castle nuts for that and thought the clear coat on t...

Re: Gauge glass fitting

Brian, Yes, Baldwin did use copper tubing for much of the cab needs. It is usually very heavy wall material often with custom ends brazed on complete with coupling rings. Recently I was tasked with the manufacture of a replacement steam supply line to a lubricator. The supply line was 1 inch in diam...
