1/4" might be a bit hard to find as a one off single piece purchase. Plenty of metric sizes that are close -...

Most likely a zinc alloy. It's relatively heavy and cheap to cast because it melts at a low temperature. It's unlikely to be any kind of cupronickel alloy as that would be a very expensive metal to...

The material constituent that gives stainless steel it's value is nickel. Generally speaking all stainless that is magnetic has little or no nickel in it. Some scrap dealers, where they are dealing...

I worked in scrap metal for 6 years in Australia and never saw a square section of 316 in that time, only flat sheet and pipe. Is there any chance that 316 might be used on the North Sea oil rigs?...

The most commonly available highly polished, magnetic stainless is 430. For a positive identification an XRF analyser could certainly do the job. Do you know a scrap merchant that has one and might...

Imperial made in Sweden, that is strange, but I guess anything is possible. 13 tpi is suspiciously close to 2mm thread pitch though?

I'm afraid you generally get what you pay for when it comes to carbide tooling. Tools suitable for use on materials up to HRC45 are a common starting hardness. Tools to handle material up to HRC65...

The courier company is unable to control customs clearance so they build in a margin for hold-ups in Customs. As for Auspost not being 'that slow', sometimes they are!

You can't buy quality carbide tooling for that amount of money even if you're dealing direct with the factory and buying in quantity, so you've probably bought junk. That doesn't necessarily mean you...

I wouldn't be welding a wheel that has deteriorated to that extent. This is probably an old Holden wheel, they used to be very common on trailers and caravans. The stud pattern is 5 x 108mm (4-1/4")....

Showing your age! We're all older than we think we are! :rolleyes:

I, for one, would at least like to hear what these idea's are. Shoot from the hip Evan! :rolleyes:
