I'm lucky that my Ex-Wife saw the ad in the paper when they were hiring. When friends ask me what I do I tell them I'm a professional tinkerer! T J

The Design Shop / Re: Scraper Blade Material
« Last post by Pete. on August 20, 2017, 01:31:43 AM »
Hey Guys, thought I would ask the smartest group of guys I know for some advice. I've designed and had a floor scraping attachment made for our skidsteer. We have a large paintshop and when the fire commisioner came through last, he commented that we can't let the paint build up on the floor. So it's been about 2 years and the paint is about an inch thick, all types from enamels and epoxy's. The scraper attachment itself works great and the skidsteer can put enough pressure down to get under the paint, but I'm not sure what to try next for the actual blade. We had a bunch of QT100 plate laying around, so I made the first blade out of it, but it only lasted a few hours. (which I was actually surprised about...)

What would be the ideal material and heat treatment to make a tough and durable blade. It measures 18" x 3" x 1/2" thick with a 30deg bevel.

Thanks in advance.

Paul

I'd go with AR plate but I would put it on the underside so the bevel is against the floor and the flat face on top. It'll self-sharpen then.

Fun little project. Belt comes off quickly for manual use.

Well it has landed but had to come down the alley on the forklift
Thats my son in the t shirt.
We cleaned any remaining chips and coolant tank then installed the conveyor.
We also were given a few soft jaws!
The motor says it is 29.5 hp at 57 amps and we would like to get a mill with about  7.5 hp so what wil I need for power a 40hp converter?

Like efrench said, I'd be leaning toward AR400 or even AR500, though I recall knowing at some point that the QT alloys are similar. It isn't definitive, but maybe helps in your search.
