Looks like I can't get a good 3' long camel back scraping reference for under 300$. And as a home hobbyist, that's pretty steep. It would require getting a reference granite plate too that's at least 3ft wide or long to even scrape in a used one, which means also a boat load more money.
Enter the idea. I was going to take a stock bar of cold rolled or hot rolled steel and have the surfaces ground to create a long bar that I can use as a reference to scrape the ways. I would send the bar to a local shop to be ground on a machine, which would save me money. And I could buy a smaller reference granite plate because for the most part, my projects won't come anywhere close to that 3ft width.
So...which kind of steel should I use? Cold rolled or hot rolled steel? And, does this seem like a good idea? The machine shop I'm going to use guarantees parallelism/flatness to within .0001" with a surface finish of 8 micro-inches.
If I get enough feedback to go ahead with this, I will give it a shot and post updates of my scraping progress for others to follow.
