Hi folks,
Anybody know what the metal used for weight-lifting weights is?
I have easy access to loads of these, most are 5kg or 10kg and thus measure 180mm x 30mm upwards.
I have a few projects in mind to use them for - As the disc on a disc sander, as the basis for a fixed steady on my Viceroy lathe, and potentially a series of them stacked together to make the large-bore pneumatic cylinder for my power drawbar.
I'm hoping they're a form of cast iron and will be turnable on the lathe but I thought I'd check if anybody knows what their properties are for sure.
Cheers,
Rich
