The Dutch Laverda Museum V6
Yet More Gearbox Parts.... I am working on several things for the V6 project, but the gearbox has the priority. I am turning and milling the gears myself, but the gearcutting and hardening processes are done by another company. Fortunately the relationship with that company is very good, and consequently I am forging ahead with finishing all the gears before I start other parts. They understand that this is a special project and that motivates me to make all the parts they are required for. After many hours of toil, most of the gears are finished now, including the many gears necessary to drive the oil pumps, generator, starter motor and so on. And so work turns to the shafts required..........!!! For me this is an exciting job because i did not succeed in finding a company that had the right milling machine to make the splines on the shafts. So I had to find a solution for this myself, and I am pleased to say I am very satisfied with the result even if initally I had my doubts about it. The gearbox requires a few small springs and also a large one for the cush drive, these have now been completed by a company specialising in spring making. There is also some progress with the shifting drum, after somemore research and calculations with my AutoCad system the programs have been made for the shifting drum and are in the machine now. Unfortunadly this specific machine is in high demand so I have to wait for a more quiet moment to produce the drum. But fortunately there are some more things to do............................................. Enjoy your watching. Will be continued again......................................... |

The rear drive shaft for the prototype. |
With help of a centre at the end, the shafts are made from solid steel bar. After this they get an annealing process to reduce the stress. After the first heat treatment process they are turned up to the final turning sizes, then milled, hardened and ground. |
Shaft for clutch and cush drive. |
Some shafts partially machined. |
Cylindrical grinding a distribution gear. |
A grinder and his grinding machine. |
The CNC milling machine with the conventional tools. |
Normally the shaft splines are milled in the same way as the gears (hobbed). In Holland these special mills were not available and so splines were milled in an alternative way. With help of old tools but......still very accurate! |
