The timing chain needs a 1mm spacer in each crankbolt as the chains are just too close for comfort and I added a 1mm spacer on the inner 36 too to get a little more space to stop rubbing on the 52 when the cassette is on a smaller sprocket.
Overall I'm very happy with the conversion.
If I am understanding it correctly you converted it to right side drive using the outer (normally where the 52 goes) as the timing ring?
Using a 36 as the granny and 36 too as tining? and what did you use as front crank?
