i was told by an engineer from temkin bearing that rollers that are barrel shaped are 52100. if they are straight or cone shaped they are most likely case hardened.

metabo hands down, the best!

to anneal " soften " steel you must bring it to critical temp and cool it very slow. hardwood ashes or " oil dry " work well. even dry sand.

i talked to an engineer from timken bearings and he told me the ball bearings are 52100 and the spherical " barrel shaped roller bearings " are 52100.

wayne goddard has a very good video on making cable knives.

a book called " the hand forged knife" and " the master bladesmith" may help.

try " texas knifemaker supply " or " admiral steel" on line.

any tang adding should be done with " silver braze " not welding. welding causes too much stress in the steel. use a scarf joint

any tang adding should be done with " silver braze " not welding. welding causes too much stress in the steel.

go to " texas knifemaker supply " for info on different belts.

go to " junkyard steel " and find a chart of the different steels and their uses.
