Homemade headlight reflector with LED
Posted by Graffen On 03/22/2018 At 2:41:58 PM
Latest project ....
A reflector with light for my narrow-gauge locomotives.
The diameter of the reflector is 4 mm.
The LED is 0.5 x 1 mm!
The reflector is made out of aluminum from oven trays.
I took a nut of the right diameter and slowly pushed the aluminum with the rounded top of the hat from a ballpoint pen.
Then I rough cut the edges and filed it to shape with a needle file.
I then drilled a 0.8 mm hole in the center of the reflector.
I glued the LED to the backside of the reflector with epoxy.
The LED is a bit too white, so it'll get a drop of Tamiya transparent orange.
Then I'll take Microscale Crystal Clear and fill the reflector so it gets a lens.

LED Light testing How-to & Homemade testers
Posted by desertdrover On 03/19/2018 At 3:45:11 PM
There are many questions from Forum members on how do I test an LED. Here are four (4) How-to ways to accomplish this task. Depending on your needs or skills these are some pretty simple ways to get the job done. Starting 1: with a Digital Multimeter, 2: using 9 Volt battery with 1K Ohm resistor in-line homemade tester, 3: using two (2) double ďAĒ batteries, or 4: a nifty little gadget from Ngineering using a Nine (9) volt battery with a circuit board with installed resistors for testing LEDís.
Starting with the use of a Digital Multimeter, connect the Black test lead to the COM jack and the Red test lead to the Note that the polarity of the Red test lead is ď+Ē).
Set the meter Function switch to the range (see picture below) and connect the test leads across the diode/LED. If the LED does not light, switch your red and black leads on the LED. When the LED lights whatever black lead clip is on your LED leads will be your (-) Neg. Cathode lead and that is where your resistor will be placed when installing into your Locomotive, Rail Critter, Structures or any LED lighting situation.

Second method using a homemade 9 Volt battery with 1K Ohm resistor in-line homemade tester. Get a set of red and black wires on a 9 volt battery snap on clip, and place an LED holder, or red and black alligator clips, on the other end of the red and black wires. Place a 1K Ohm resistor in-line on the black wire. To test an LED, place the LED into the LED holder, or use your alligator clips, and again if it lights, note what lead the black wire goes to on the LED leads, and that is your (-) Neg. Cathode lead and where your resistor is attached.

Third method using a double ďAĒ battery case with two (2) double ďA batteries homemade tester. Attach a set of red and black alligator clips to the battery case red and black wires. (No resistor needed for this tester) Connect your LED to the tester clips and again, if it lights, note what lead the black wire goes to on the LED leads, and that is your (-) Neg. Cathode lead and where your resistor is attached for when you install it into your locomotive decoders White (Forward) or Yellow (Reverse) light leads.

The last LED tester is a device made by Ngineering, Part #N8021, for testing LEDís, nothing more than the same as your homemade second tester using a nine (9) volt battery and resistor. This device already has a resistor installed into a circuit board with nice convenient attachment clips for your LED leads. And same as all the other testers, the black lead shows your (-) Neg. Cathode lead and where your resistor gets attached prior to installation.

"Natural" Porch Posts
Posted by TC On 03/17/2018 At 11:14:13 PM
I'm looking for some creative ideas on how to model (in 1:87 scale) porch posts similar to the ones in this photo by Dorothea Lange (found at this Wiki link) taken by her in Gordonton, North Carolina. Anyone have thoughts on how to approach it?

Another Photo Run-By at the F&SM RR
Posted by halrey On 03/17/2018 At 6:36:57 PM
Well, I made another photo run-by at the F&SM RR two days ago. George has replaced some of the older buildings that had been built in a rush with some new structures. The restaurant with the pawn shop are a Downtown Deco kit, while the other 2 are scratch built. The fish company bldg. covers a turnout motor.
Always new improvements every time I stop by, got to love it!


Grandt Line Closing

I got a tip on Facebook that Grandt Line is closing. Hoping to get the word out so someone might pick their line up.

Most interesting site, I shall, when my web site comes back on line to place a link to here.

Since 1983 I have sold many kits to many satified cusomters, however due to the tough economic times and the deluge of modeling equipment dumped onto the modeling market, most customers cannot make up their mind as what to buy and purchase nothing.

Remember when, Mr. Athearn and his company would announce a new car type about once each year. The new car would be manufactured in ten road names and priced within the means of common modelers.

Now everybody in the marketplace is scrambling to put out as much and more than the buying public can swallow. Note as well the great number of model railroad stores simply throwing in the towel and exiting the business as too highly competitive and or too much to keep in their modest inventory.

Worse, is the way companies do business, buying a lump trailer full of trains and once sold or out of parts to maintain them, they say to the customer, "That's Tough!"

My business too feels the crunch, and mattering on this year's sales figures will make our mind as to remaining in business or slipping from sight.

I have recently come across many interesting items, that I am hoping someone out there can help me with. original plans and scale drawings for a stream line scale type elect. train submitted to Lewis marx in 1950, I also have #1 produced still in the box. #32250 I am looking for some direction. any comments or suggestions would be helpful.
Thanks, Douglas K. Lee

If anyone knows where these station where at and the distences, please write to me at ray_acosta@q.com or jraycost@gmail.com, thanks.

This is the second or third time I've visited the site. Its very good and I've enjoyed reading through many of the posts. Unfortunately I do NOT have high speed internet at home, so don't spend alot of time (1/2 of the week) on the net. When I am down near work I do.
I am building the Cascade Div GN prototype in HO scale between Skykomish and Appleyard (Wenatchee) Wa. Time stopped in the fall of 1953.
Thanks again for the site.

I need information on a Tortoise switch machine. The switch runs on DC current. Can I also attach AC current for the frog?

Greetings from Germany to the N-Gauge fans in U.S.:

Administrative Edit: the attached photo had to be deleted because of file size restrictions and complications with home page/Guestbook spacing.

Photo shows "modified" Arnold BR 95 in 1:160 which is surely 20 years old.
