Beautiful work.I just wanted to mention that OnLineMetals now carries Durabar https://www.onlinemetals.com/en/buy/cast-iron-round-barThey never previously carried any cast iron so this is a good thing. I don't have a lot of experience with Class-40 but it seemed to cut & finish OK on my cylinder liner tester. I bought enough Class-40 to do my radial engine so that's settled, but for future projects I think I want to try Durabar. It was a double win because Speedy is net more expensive to me (in Canada) as their material prices can be a bit higher than OLM but the (UPS courier only option) transport costs are killer. If you live in this States all this is a moot point, but just pointing out to others who might be reading.
Great work, Chris!Love the beauty shots. You've cut that chunk of metal down a lot for sure! It's lost over 75% in weight!Kim
>I looked at the Durabar there, choked on the price though. The class-40 from speedy metals was 1/10th the cost, so I am starting with that and will see how it goes. Yes, in 1.25" diameter I was looking at, Class-40 Rd Grey cast iron via Speedy is 18.95 USD/ft. Durabar via OLM is 46.11 USD/ft. The transport all-in cost brought the numbers closer but its still expensive stuff. Another thing I noticed Speedy has an excellent selection of rectangular Class-40 for similar $/weight cost metrics whereas Durabar $ is stratospheric, not even worth discussing. Maybe that's where you were getting the 1/10 factor. Sorry for the sidebar diversion.
Chris, online metals only sells durabar in 72 inch lengths. So 70 bucks is not unrealistic. But shipping would be high especially if you only needed a couple of inches. The accountant (bean counter) in me. Sorry
