Plunger belt drive
« on: 07.01. 2011 23:13 »
Came across this on evil bay. Its the first belt drive set up for the plunger models I have seen. I have no idea who the seller is or the quality of his stuff but it may interest some.

Personally I think the original set up on the plunger models is more than adequate so there is no need for modifications like this.

G'day Brian,
                Yes saw that. I have one of his on the cafe with a sNorton clutch and a friend has one on an Atlas, am very impressed. I also have a belt dyno drive from him as well as a sprocket nut with a seal to eliminate any leaks between the main and counter shafts. John is his name, quite a helpful bloke but will talk the handle of an iron pot.
Cheers

No adjustment needed, set and forget. Belts run quite loose compared to chains.
