CHAIN DRIVEN COUNTER – FINAL ASSEMBLY

I received the Veeder-Root counter from Danaher yesterday. Today I put together the final version. See below.



It’s mounted on the left side of the bike, and counts increase as the bike rolls forward. The bracket is made from light-gauge aluminum, cut to size with tin snips. There is a slot where it mounts to the axle to permit forward-backward movement to get the chain just right fore and aft. Side-to-side positioning was achieved by bending the bracket. The chain is adjusted so that there is a little bit of slack at all times, which eliminates any tension beyond what is needed to rotate the counter. I have ridden it about 5 miles so far with no noticeable aggravations. I think it’s now in its final configuration, at least until another Eureka moment arrives.

The constant appears to be about 20,000 counts per mile, which means it will roll over every 5 miles.

A good test for the thing will be a ride on some brick pavement. We have a few brick streets in Columbus, and they are boneshakers.
