    Making lathe from scratch and using mild steel plate? Why use cast iron?

    I was thinking using say 19-20mm plate (3/4") thick. Make a big webbed base section and fill with epoxy resin and sand/pebble mix.

    Making lathe from scratch and using mild steel plate? Why use cast iron?

    Yeah I was thinking of the pottery guys, there is a large mod that have a pretty big kiln they use to make pavers and fire bricks etc. I will have to phone around and ask them. I should ask the specialists too how much to properly stress relieve. I should ask the foundry up town how much they...

    Making lathe from scratch and using mild steel plate? Why use cast iron?

    Okay 1150 F is 621 degrees Celcius. I reckon I can get that with a few bottles of propane gas, yeah? Make up a bit of an oven and cook it for a few hours. Should be easy enough. For the ways, I'd just bolt down and shim some hiwin type square block type ways????

    Making lathe from scratch and using mild steel plate? Why use cast iron?

    Right, intro post done. Well I'm thinking that I can get an old mill rather than a new one and it will be cheaper. Then I could use mild steel to weld up a lathe frame and machine it out. Then use the linear ways for the X and Y axis etc. The idea is to get the most from your dollar. Still...

I have a little practice with using a lathe and milling machine when I did a part time engineering course a few years ago. I guess I'd like to find out more details about machining...

    Making lathe from scratch and using mild steel plate? Why use cast iron?

    Why are all lathes and mills made from cast iron? Could I weld up a structure out of mild steel plate to use a a lathe base and frame? Then just face mill or fly cut the surfaces in a mill? I think you would need to flame stress it right? So you weld it, machine it then flame de stress it...
