Does anyone have a source for cheap stainless steel tubing. (I am trying to build a piston)
I have previously got stainless pipe from exhaust shops and stainless rod from marine manufacturing/supplies businesses. Neither were cheap… sorry.
Best I can find is http://www.ebay.com.au/itm/STAINLESS-STEEL-ROUND-TUBE-9-53mm-DIAMETER-X-1-2mm-X-300mm-LONG-/111107460151?pt=AU_Business_Industrial_Construction_Building_Materials_Hardware&hash=item19de854c37
I know of a bin with lots of huge chunks of stainless. They’re worn hydraulic rams. no idea about machining it, but its definitely big and definitely stainless.
Hydraulic rams are steel with a chrome coating.
