Re: Long Island ALCO Century 420 in construction.

Re: Ideas needed for spring equalized truck

My friends side to side play is about 5/16" each way, 5/8" total. Keep in mind that the trailing truck aids a Forney in navigating curves by preventing the "waddle" effect especially with such a long back end. The track we tested it on was FAR from perfect. Large dips and curves with less than a 30 ...

Re: Ideas needed for spring equalized truck

When my friend Ed built his kitbashed Forney, he used Mercer's Reading A5a tender trucks as a base. A simple swing link setup was built with the links hanging from the cross bars down to the lower portion of the bolster casting. Nothing fancy and close to prototype. His locomotive tracks beautifully...

Re: Machining Side Rods - Allen Mogul - advice needed

On most full sized drawings from "back in the day" materials were rarely called out. One would have to go to a list of standard materials buried in the makers standard practice manuals. If the customer were to specify a non standard material in their order sheet, a "Question customer" flag would go ...

Re: Copper Pickling Question?

Pardon my delayed response. I use a product called Oakite 31. The is a phosphoric acid product that is designed to dissolve brazing flux by just soaking. When I did my copper boiler for the 4-4-0. I cut the top off of a 55 gallon plastic barrel and set up my outdoor pickling station. The recommended...

Re: Combination squares

I am constantly swapping rules with heads of different brands. Especially when I need a bunch of tools set up all for simultaneous use. As long as there isn't too much slop in the blade fit, it should work Also, make sure the tang on the blade lock fits without forcing or falling out of the slot. So...

Re: Long Island ALCO Century 420 in construction.

They are very wimpy looking trucks. Something that Buddy-L might put out. Even the journal boxes and springs seem way too small for a passenger car. You may be able to get the whole side frame stamped out from one piece of sheet stock like the prototype. Add some detail rivets and you'll be done. I ...

Re: ????---3D TASTER

I was at a manufacturing show in Philly not too long ago and the big thing was 3-D scanners and Printers. Someone had the bright idea and scanning a slice of pizza with all of the toppings. The result was a perfect copy, color and all, of the pizza slice. Someone then asked if the company has invent...

Re: Long Island ALCO Century 420 in construction.

Is that the "ping" end or the "pong" end? Those from LI will understand. You'll have to fabricate one of those goofy pressed steel truck frames too. We have one or two at ST if you need measurements or photos.

Re: Way oil filter check/change?

All of the older Bridgeport knee type CNC mills that I have seen, had automatic Bijur way oil pumps on them. The only filter was the cup shaped 2 piece removable screen at the base of the pump. I don't know how much you use the machine but I would inspect / change it once a year. Make sure the fille...

Re: Franklin Automatic Adjustable Wedges

Wedges can go a lot more than 100 miles before adjustment. They should be checked and adjusted, if necessary, during every 31 service day inspection. We often go for more than the entire season without any noticeable wear.

Re: How to distroy a steamlocomotive with a wheel slip

The first video, the Blue Peter Slip, looks more like a dry pipe failure or possibly a throttle valve break. The fact that the steam continues to flow without showing any signs of slowing down leads me to this. Most throttle linkage failures result in the throttle valve shutting. Even the balanced t...
