Very nice work Peter. I presume that the three sets of fixing holes are for three different Change Wheels. What tooth numbered wheels did you fix on and why? Many thanks for pointing me at this thread. Regards John |

Thank you very much everyone! --- Quote from: JohnDK ---Very nice work Peter. I presume that the three sets of fixing holes are for three different Change Wheels. What tooth numbered wheels did you fix and why? Many thanks for pointing me at this thread. Regards John --- End quote --- Quite correct John, the three sets of fixing holes are for 45/50, 60, and one larger gear, but I suspect that it will be the 50 (on the pic) and the 60 that will be the most common ones. I did them as separate holes to avoid sliding if I miss securing the thumb screws and it also adds to rigidity as well. In fact, the holes are 5,5 mm to guide the countersink and the screw hole is M5 so the thumb screw has a shoulder to guide the console properly. BR /Peter |

Many thanks for your reply Peter. Is the Detent housing in two pieces to enable a spring to be fitted and where is the join? Sorry about all these questions but I find this design very interesting. Regards, John |
| PeterE:
I think the easiest will be to show a picture of the dis-assembled detent. From left to right: The housing is made from a dia 20mm brass. The thread is M12x1 to fit to the console and the hole is 8mm drilled for about 90% of the length. Then the hole through is just 4 mm to pass the stem of the detent through. The detent is made from a piece of 8mm mild steel with a filed screw driver type edge to fit the gears. The spring is a part of a longer one I found in the scrap box, hence the man-handled look The top button holding it all together is lying upside down to show the M3x4 grub screw. Finally, the hold-out conically countersunk on both sides and milled out to be able to attach it without having to part the whole thing. Hope this helps. BR /Peter |
