Rango - Build diary

[Ellis]

Hah, cheers PJ. The amount of time that goes into doing this stuff by hand is surprising, I want a mill! But:

I made that plate by scribing the dimensions on the raw material and cutting it out with a hacksaw, then filing to size. I marked the positions of the centre hole with more scribing (from the edges), centre punch, then drill, then used a 25mm forstner wood working bit to scribe the radius for the bolt pattern from that centre hole. Find what should be the distance from the edges of the piece for the holes (cad helps for this) and scribe from all sides, giving me the hole positions along the previously scribed bolt circle line. Centre punch, drill, countersink, bish bash, rub the finished product with some wirewool to get the ugly raw material finish and scribe lines off and ya done.

tl;dr: scribe the everything. I don't know how I/we managed to build anything without scribes and centre punches, lol.
