10-sp frame conversion https://raleightwenty.webs.com/apps/photos/ 10-sp frame conversion Flush inner surface A 10-speed Shimano cassette is being fitted to this frame. The lower (bullet shaped) section of the Raleigh Twenty RH seat stay protrudes inwards, beyond the inner drop-out surface. This has to be removed and made flush to provide the necessary chain clearance, The surface of the tube has been ground away using an angle grinder. The edge of the tube has been filed flat. The void in the tube has been filled by cutting a 3mm thick steel plate to fit accurately, and brazing it in. https://raleightwenty.webs.com/apps/photos/photo?photoID=204130884 204130884 Skinny! The tube is left rather skinny! But, with a 3mm steel plated brazed into it, it is now almost solid, and stronger than the original configuration. The plate continues upwards inside the tube, above the cut away area. The chamfer in the tube was filled with a piece of scrap steel and brazed over. The work was then filed to a smooth finish and squirted over with aerosol paint to prevent rust.

This modification to the seat stay will mean that the chain will not clash against the inside of the frame when using the smaller sprockets. This was about two hours' work, and great fun to do. https://raleightwenty.webs.com/apps/photos/photo?photoID=204130886 204130886
