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.

Nice site. Enjoyed looking around. Am in the early stages of designing a layout. As a kid, I ran Super O track and am considering making the layout using Super O track. Availability of wider radius curves is an issue. Will prob end up modifying the existing (36" dia circle) curves to increase diameters to 60" (5'),72" (6'),& 84" (7'). So, I was just looking around hoping to get some layout ideas.

I bought my first HO model train set when I was 12 years old, had it on lay-away at G&G Model Shop in the Village, Houston, Texas. I have loved trains all my life. My Grandfather worked the old Yazoo & Mississippi Valley RR (with John Luther Jones), I.C., Gulf Division, L&N and retired off the MoPac. He and his half brother owned the Louisiana Southern RR, which ran through the truck farms in Barataria. He had box cars loaded under guard (holding Thompson Sub-machine guns.) My mother went once and it never occurred to her, veggies need no guard, but Hooch does.

I have been away from this forum for a few years and cannot remember details of my original registration. Cannot find a way to gain access now. Need to know my forum name and password. Can anyone help?

Thank you for a great place to enjoy train lore. I have always wanted a wooden boxcar of my own but settled for trips from Chama Co and Durango Co. I live in Trinidad Co and would love to find a door or two off of an old car. To setup in my backyard as a backdrop for pictures. I do this strictly as a hobby as I am retired and gave time to make things happenAny help in locating a door would be greatly appreciated. Thank s

I tried to post this after registering yesterday, trying again to be sure as I believe the topic is important...

If someone is still looking for a link to some of Tom Beaton's work:

I talked to him last weekend at a show in Chilliwack, BC. He has a folio with his published articles (technical details and drawings) and lots of pics of his work (mostly in other people's hands). I asked if he would like to have it scanned and placed on the net by volunteers. Am not sure if he got the intention but refused, stressing his dislike for computers.

This would be w worthwhile project for the modelling community. If you need me, contact form is on my blog:
right-hand menu just above the internal search button.
