so if I was you I would order your couplings as soon as you can.

Yep, that's the plan... get all the hardware, check it against the estimates I've been using and then tweak the metal work to suit in the design and then order the metal and start the build...

Pre machined.

The design is going with me to the shops so I should be able to see if anything is going to cause me any problems before I part with any cash. I'm sure there will still be some surprises.
