NICE JOB, I HAVE FIVE TEN FOOT RAILROAD TRACKS THAT I BOUGHT 15 YEARS AGO. AS IT TURN OUT THE HAVE THE "CARNEGIE STEEL CO" LOGO FORGED INTO THEM AND I FOUND OUT THAT THEY ARE QUITE VALUABLE. SO I HAD TO RESORT TO EBAY TO BUY FOR COMMON RAILS AS THESE ARE WORTH UP TO $1000.00 A FOOT.
ONLY DUE TO THE HISTORICAL VALUE THAT CARNEGIE MADE THEM IN THE 1800'S.
Took four 2mm cut off wheels. One 8mm grinding wheel. ( only partly ) Little from 40 & 80 grit flap wheels and 80 and 120 grit fiber discs.
For the stand one and a half 1mm cut off wheel.
Something like that..
Grinding wheels and fiber discs we're 3M Cubitron 2 products, those work specially well with hard materials.

Made a new RR-track anvil.
Lenght 450mm / about 18"
Made with the same way than earlier one.
This is also for shaped for shaping sheet metals.
Hardening was made in heat treating oven. Started with preheating it to 660 degrees of celsius, temperature was raised 200 degrees / hour. Then it was heated to 1000 degrees and hold in that temperature 30 minutes.
After that it was cooled to water. And finally heated to 300 degrees of celsius and kept 4 hours in that temperature, and cooled to water.
