Yesterday while trying to fix the cement mixer i needed a coupling.

You would probably pic up your laptop and start doing a CAD drawing

Actually I'd use a prop shaft repair guy I know (No lathe) but there's something to be said about the suck and see approach, was going to try and build my router without CAD but in the end I had to cad out about 80% of the router just to make sure everything fit.

As for CAD all I can say is don't give up one day something clicks and it starts to make sense, there's an initial high learning curve but get over that curve and it gets a lot easier. It took me 3 attempts at learning before I started to get it.

If you do build it yourself it's worth trying to source a local suppliers of aluminium extrusion so you can get it cut and drilled as you need it, I live next to KJN and it was invaluable being able to actually drive there to have the parts processed.
