Description

2021May14 -- I am TOP RATED on this marketplace with a current 12-month FEEDBACK rating of 100%, and I offer Combined Shipping. See my last 2 pics for my eBay Seller Level and eBay Feedback.
For shipping I have specified a handling time of 10 business days.
I have for sale several pieces of 0.25" diameter rod made of clear acrylic plastic (aka Lucite, Plexiglass, and others) very suitable for making headlight lenses for model railroad engines. The pieces are 4" long, plenty for making a number of headlight lenses.
They are also very adaptable for replacing the side porthole lenses in American Flyer Alco diesel engines. Just slightly drill out the porthole to 0.25", insert a piece of plastic rod, and secure it with a tiny spot of glue.
I have been customizing some old pre-war O-gauge engines for conversion to S-gauge. None of these engines had a headlight lens, but instead just a hole where a headlight should be. I wanted to add headlight lenses and found that I had to special order a small lot of 0.25" acrylic rods to get what I wanted. I now have way more rods than I'll ever need so I'm offering them for sale.
Pic #3 shows one of the engines I'm customizing. It's an American Flyer pre-war O-gauge model 729. Note the headlight installation using a piece of this plastic rod.
Acrylic plastic is more transparent than even glass and has 92% light transmission. It is easily worked, machined, and glued using CA glue.
For American Flyer the ALCO diesels use a 0.25" diameter lens (That makes things easy!) while steam engines typically use a 0.175" diameter lens. Pic #2 shows an ALCO lens, a typical steam engine lens, and a piece of this plastic rod which I've turned down to 0.175". Did this my simply chucking it into my drill press at medium RPM and using a fine flat file to turn it down. Polish up the ends a bit and you've got a nice lens.
Pic #4 shows the same engine in the dark and powered up, sitting on blocks because it does not have a neutral position. It has a 14v light bulb and is powered up at 14v. Note how bright the headlight is, thanks to that 92% light transmission. As you can tell by the 2 red marker lights I did not deliberately overexpose the pic to enhance the headlight brightness.
Replace those old dulled and yellowed headlight lenses in your engines now! I think those old lenses are made of styrene plastic instead of acrylic plastic.
About shipping ...
This is a tiny item and I could ship it for in a 1st class letter envelope, but I won't because that shipment would be non-tracked, resulting in ...
o A scamming buyer claiming he didn't receive it. (This has happened.)
o eBay giving me a seller "Black Mark" for a non-tracked shipment.
