Tip for Chain Adjustment - Bonnevilles

[CarlS]

Taken from the NTBF. I have not tried this; but I will the next time my chain needs adjusting. I hope it works;because it will make it easier to adjust the chain on Mae Lyne's rig.

A small tip to help with chain adjustment.

When adjusting the chain get a screwdriver with a thin shaft 3-4mm and stick it between the sprocket and the chain at the six o'clock position.

Now adjust your chain so all the slack has been taken out and do up the axle nut to the required torque.

Remove the screwdriver from between the chain and sprocket, there you go the correct amount of chain slack every time and you don't have to do it two or three times because the chain is tighter now that the axle has been done to torque.

It may take a few attempts to find the correct screwdriver shaft size and the correct position in between the chain and sprocket but once you have worked it out for your situation it is much quicker and more accurate than any other method. I cut the end off my perfect screwdriver, so now it is just a chain tension tool.

I've done basically this same thing for decades now except that I always used a pencil and I would "start" the pencil in the spocket at the bottom where the chain first makes contact with the sprocket and then turn the pencil into the sprocket by hand until it was at the very rear of the sprocket furthest away from the drive sprocket.

My biggest problem with my Hinckley Triumph with the eccentric adjuster is getting the wheel to line-up straight again while I re-tighten the axle.
