Homemade Chain Buffer

When I took out my swingarm the other day I noticed that the chain had eaten it's way trough the OEM chain buffer. I wanted to order one but it'd cost me €25 and about 4 weeks delivery. So Tinie from BikePenR arranged some 35x10mm industral quality wear strip for me and gave me some time in his workshop to let me have a go at creating my own.

First I warmed the strip using a heat-gun and bent it around a 40mm axle (the same diameter as the swingarm's pivot point) to form the U-shape. Then we clamped it into the mill and I removed a section to clear the dust seals.

A 30x2mm aluminum strip, 2mm thick holds the ends together using small wood screws.
And finally I made a 10x10mm bridge to prevent the thing from deforming.

The pictures below show the result. It has an equal construction as the OEM part but made from much harder-wearing material, cost nothing because it was made from scrap material and done in less than two hours.
