Does 36mm OD x 34mmID work for 1 1/8th inch steering tube headsets?
And 32mm OD x 30 ID for one inch steer tubes?
1.3/8th" OD x 1.185" ID x .095" wall from wicks air craft is a bit thick but the right fit.

Take a look at these for 1 1/8"
Nova Nov_COHT_37_700 1.60mm wall, 37.00mm OD / 33.80mm ID, (straight gauge, bore ends to 33.95mm ID for headset *)
Nova Nov_COFS_460_AHD 2.00mm/1.55mm wall
* Believe this came from a FSA headset guide... you should confirm with the choice of headset you are going to actually use. Recommend use w/ lugs or with a reinforcing ring/band at top and bottom
Hope that helps
