Evening John....& yes without stealing Mikes thread.........paddle wheel sets have been a very expensive & difficult issue to accept over the years
I have a set from a UK supplier which are expertly CNC cut, however the bolt size as supplied is approximately x 3 of scale which are now scrap value only
...... courtesy of [Wav****y Models] [8 years ago I openly posted my experience with this supplier and his lack of help]
The ABS [plastic] wheel sets are cost effective, however what you see is what you get.........I decided not to use the same
I have since acquired a ~~78 year old [metric dimensioned with metric bolts (not BA)] brass wheel kit and am progressing with the [rimless] assembly which will be complimented with the 36 cast brass blade supports from elde-modelbau ......the final wheel sizing will be ~~ 175 mm diameter x float blade width ~~ 75 mm
