RE: Looking for (idler?) gear wheel of HP-46 printer unit
Finally there was some time for rebuilding printer gear wheel today. As one piece solution failed due to software toolbox problems I followed Duane's (and dalmator's) guideline of glueing two seperate gear wheels together.

68 teeth Mod 0.4 outer gear wheel source:

17 teeth Mod 0.4 inner gear wheel source:

Drill hole: 4 mm, Gear wheel width (T) = 4 mm

Order was fulfilled within a week.

As mentioned bushing is not available from Steingraeber for an undefinite time I connected both wheels with a 4,0 x 3,2 mm brass tube, a default model making item:

Together with a drop of super glue double gear wheel is good enough to handle forces within HP-46 printer unit. At least I have not got any problems during several lenghty tests.

Prophylactically I repeated procedure with a second HP-46 unit where printer still did it's job. Even there printer noise went down considerably.

Thanks again for your great help.
