This was an interesting morning. Def some cool tools i need to get.
+1 for the bricks. lol
Now for some high tech stuff....The first two are not really for the household, but i still think they are pretty sweet.
3D wax printer: Prints objects in wax, which you then send to an investment casting foundry to get made out of steel, aluminium or whatever. Extremely cheap (relatively) for those one off custom jobs.
Desktop CNC milling machine & lathe: Doesn't do steel, but works great in aluminium, rubber, tooling board etc. Great for making cheap moulds for plastic/polyurethane components. Made some custom urethane washers for my mates forrester. Worked a treat.
UV chalk: Great for noob's who cant weld straight like me
