restoring 1952 D82U dozer

from my experience with applying new cutting edges to a blade or bucket, i have always used AR 50 steel. the armor plated steel lasts a really long time, but could be difficult to work with if you have drill holes. it took me 3 days to drill 8 holes for teeth on a excavator bucket, that i was using armor plated steel on.
if you are only using your dozer 30% of the time and the rest of the time it is sitting, you could get away with 4140 steel. if you go mild steel, you would be wasting time in my book. that stuff isn't the best for these applications. i am sure that some of the other people on here could set you in a better way. these are just some of my recommendations.

Not personal experience but passed on information.

IF you need a 1" hole that is what you drill. NO stepping up as the drilling process hardens the metal. It is tough to start with..

Whay not buy a cutting edge and modify it if necessary?

Or do you want to replace parts behind the bolt on edge or what?

thanks for all the infomation this is my first time posting on this site and a toolmaker and thought it would be cheaper to build cutting edges had no clue about prices

Replacing cutting edges should not be that big a deal. I have not bought any in a few years, and steel has gone up but i don't think I paid $100 for new cutting edges for my CAT 12 grader the last time I replaced them. I wouldn't want to drill all those holes unless it really paid. Hopefully, there is a company like Wear Parts in your area that sells cutting edges and can fix you up.
