Update
Today I moved to the rear of the trike and the mounting of the disk rotors...well that was the plan in reality only one rotor was mounted after 6 hours of cutting, sanding, swearing, sanding, swearing, removing a large piece of cutoff disk from my eye worst 'eye injury' i have had in all the years i been working with tools, took a good 30 minutes of flushing with the garden hose to get it out (
and YES i was wearing safety glasses at the time!! NEVER start a power tool without putting them on...take not kids you only get one set of eyez) this of course was followed by more swearing LoL...
My rear trike hubs are a non-disk brake affair and thus i needed to make adapters for both hubs
(for those that aren't aware, one of the wheels is non driving wheel and simply freewheels so a single rotor on the rear axle to stop both wheels isn't an option unfortunately) I knew without a lathe this was going to be big ask to get true, i decided instead of starting from scratch making adapters to butchers a dual front disk hub i have that i wont be using (will be using a single with a 200mm OD rotor instead as my forks are single caliper mount only) My initial idea was to simply cut it down drill 3 mounting holes and bolt it straight to the trike rear hubs, this would have worked beautifully, would have been nice and square and true BUT i hit a snag when attempting to drill aforementioned mounting holes, the front hub was a pressed unit made of three pieces, one of these pieces was hardened stel and thus i was unable to drill it, at this stage i knew i would be in for a looooong afternoon. I cut the mounting section of the hub down further to eliminate the hardened steel section and was left with a solid piece to mount to the hubs, this of course need to exactly the same width overall so the disk would spin without a wobble...after ALOT of lapping measuring with verniers lapping measuring mounting lapping etc etc etc add 4 hours i came up with the following-->
I have only mounted the rotor with 2 screws at present and it is pretty close to spot on, the adapter is held to the hub via 3mm countersunk high tensile steel allen key bolts, i would have preferred 4mm but there was simply no room for this 3mm was a tight ask, i believe these will be plenty strong enough :: fingers crossed :: lol... its the best i will get it without the use of specialty machinery namely a lathe which alas i no longer have or have access to :-( Here's a quick vid of the rotor mounted and spinning-->

I shall mount the adapter for the other side tomorrow, i wont be mounting it to the hub as i did this rotor but to the plate on the axle with the 3 studs on it that sits flush against the hub...more on ~ this time tomorrow...
ciao for now
