Looking for info on building my own tandem and maybe a solo trike.

Because of my wife's health issues regarding balance, but still wanting to ride a bike, we decided to get a tandem. BUT, good quality tandems aren't cheap, and I don't want a Walmart type bike. I've read a bunch of stuff online, mostly through Sheldon Brown's stuff... The bike won't see high speeds, and won't see trail use. Mostly flat and slow bike paths.

I'm picking up 2 Trek 950s Monday. And believe I have a line on some chromoly tubing. My intention is to use a larger diameter tube (probably 1.5") for the main bottom tube, and possibly the same tubing to sleeve and extend the rear top tube to the seat tube of the front bike. I'm not sure if the front top tube needs sleeving. But I will add a brace behind the headtube to give some support between the top and down tubes.

The other part of the question... WHAT is required and where can I find parts to build a trike from a standard MTB frame? I have an older Trek 820 that would be perfect for this.
