A go at casting

Posted on Updated on

I recently wanted to get a feel for how difficult casting may be. A bit of trial and error going on here which seems a subject with actually very little detailed information on google – lots of high level but I failed to get any decent examples.

So jumping in I used some rubber tool silicone to make a negative cast which I then made a wax mould from which in theory I could then cast with investment powder. Lot more experimenting and a good book needed to proceed I think. But not a terrible outcome from an afternoon just jumping in and experimenting.

The idea being that with a good wax cast (and I think I had the wrong wax) I could make a number of patterns that I could cast in brass using some equipment available to me.

Today there was a build-your-own-quadcopter workshop at rLab. The designed in-house, the main elements of the airframe cut from acrylic with our laser cutter, and all of the parts ordered and assembled into kits in advance.Total price per quadcopter – ~£100!

The build was a great success, with eight out of nine of the quadcopters in flight by 5:30 – the ninth had a faulty motor.

Unfortunately I didn’t find the acrylic very robust for an amateur pilot, so I recently upgraded to a carbon fibre frame.
