Not TR1 specific  

My garage has a downhill slope into it and it is a pain to be reversing the bike down into it.
I can ride it down, but then I have the problem of turning it round.

So, I bought a heavy duty, 300 mm diameter "Lazy Susan" bearing with a load capacity of 450 kg. from Bangood (Cheap!) Heavy-Duty-Metal-Bearing and a pre-cut roundel of 5 mm thick aluminium with the same diameter from Ebay - also cheap - Scheibe-Aluminium 300x5

Its a simple job to bolt the plate to the bearing with M6 nuts & bolts. The bolts need to be cut as short as possible to avoid fouling.
I think I made mine 8 mm.
After assembling and testing that the bolts don't bind in the bearing, I centre-punched between the bolt and nut to lock them.
The plate and bearing are 15 mm thick so its not too hard to get the bike on the stand
