What the track bolts go through and hold the rail ends together are called "angle bars" and I'm guessing you ain't talking about those, right? :)
I think I know what it is tho but there is so much of that weird shaped stuff tho and bridge parts too.
I'm thinking it's the spacer+holder between the "stock rail" and the "switch point". It's really heavy-duty looking... if laying like it should you can see how it's made to fit inside, next the web on both sides of it so it's sort of symetrical.
For the most part you are right... just until you try carrying off the whole pile at once. :) A piece or two at a time know one will care. But really the best setup for you is to get to know the workers they'll had you hunks of fresh cut rail and all kinds of stuff that's better than what's prob'ly in that pile.
I have a few pieces of rail too of course ;) and used to make a point of collecting all the neatly cut pieces to give a away.
Standing on end is a real good use. If the end was "friction saw" cut (chop saw;) then that surface might be so hard as to not be filable! :)
I'm going to guess those are "rail anchors" or the common name is "creepers". Is that what they are? what's clipped to the underside base of the rail and when there's enough of them tight against the ties the rail won't scoot along or "creep along" from train traffic.
Actually the dangged rail on single track territory shifts back and forth but still scooting on the "tie plates" is bad for a bunch of reasons. Rail anchors are spring tempered steel and a spark test will be needed to find the carbon content but I'll bet it's something in between the rail at 1075 to 1080 (like a cold chisel) and an HC marked spike. Guys at Enderes wrote me a letter and told me their punches and chisels are made from 1078 so that's a known sample for all of us.
Automotive springs are a jillion different alloys but boil down to one catagory-> "a low alloy medium carbon steel" might as well figure them to be 5160. Somehow I always figured (never spark tested them for some odd reason) creepers to be about 1045-1060.
You spark test yours and then we'll both know. :)
That's what I use but it's all homemade.
Did you ever cool it quickly?
If it happens to have some alloying in it, it could be partially air hardening in the thinner sections but that's a stupid wild-ass guess and doesn't really mean anything. :/ There's not enough information to know what's going on, sorry. :/
Like the other poster said -grinding wheels-! :)
Cool. :) But is it a new file? :/ Big difference sometimes in just the sharpness of the file or the pressure applied.
My guess is straight medium carbon steel... spark testing needed. :/
I'll see if I can round up a few samples to spark-test too.
Sorry, I'm not a flat grinder... :/
When you figure out how to grind something flat without a special machine to hold and guide everything... let me know ok? ;) I can hollow grind a knife blade until it's paper thin but never have made a good looking job while trying to make a flat-sided knife! :)
Well there's the "clunky old magnet method;) you know about that one already? ;)
I use the "arrest point method". :)
Those are -my- names for them not sure what others call them.
Spark testing will tell you more, for sure, faster, than anything else... no kidding on that... even if you first have to learn to spark test, it'll still pay better than experimenting blind.
Never-ever seen that. The wornout track tools were supposed to be cut up before they were thrown in the scrap pile but weren't most of the time.
The "work train" picked up scrap metal with a magnet and 39' and 78' rails were loaded with the magnet too but they did a pretty good job of keeping all the different kind of parts separated into different cars. It was worth more that way? Colorado Fuel and Iron didn't have to mess with it so much to prepare it for recycling into the same parts again? ...is what I always figured.
They just dumped the stuff into "gongs"... "gondola cars".
Then there was the "ribbon rail train" that unload new rail in 1/4 mile pieces and then later came by and picked up the old ribbon rail.
What I'm really into is making knives from power hacksaw blades. I've got a stack of used blades that I started collecting right after I first watched a test of the new chopsaw/"friction saw" made from a chain saw.
If you talk to the guys working along the tracks (not the trainmen) you might even get a few of those high speed steel power hacksaw blades or maybe just used chopsaw blades? :/ It takes a brand new blade to finish cutting through a rail so "small pieces" aren't any good to them really ...but for free they are plenty good for most every other kind of material you're going to want to cut. And they'll have extras to spare.
Nope. I don't have a chopsaw I use a hand grinder. :/
