  • Toolpost material

    The toolpost for my new old 16" shaper is missing, so I need to make one.
    Obviously, it's going to take a lot of stress. What type of steel should I use? Do I need to harden it? If so, If I need to harden it, what color/temperature should I draw it to? Thanks.

    Im sure somebody will offer a diffrent opinion but I think any tool steel would be ok to use as long as you end up at 40-50 rockwell c scale. You might be able to get away with 4140 untreated as it is about 30-35 c scale to start with. If you got the cash s-7 would be my choice. It's very tough and impact resistant. We used it in extrusion dies and it held up extreemly well. Hope this helps.
