Yamaha TD1B bike lift brackets

I wanted to use a modern rear bike lift for my TD1B but did not want to weld brackets or studs on the original rear swinging arm. So I tried to make detachable ones.

I am only a hobby engineer so many of you can surely make something better! Thinking about how to do it I thought it easiest to make a kind of clothes pin that can slide over the narrow swingarm/chainadjuster and can be fastened with a 6 mm bolt/nut. Here is the final small product on the bike:

To make it I used simple 20 mm aluminium stock. The rods are left a little longer in order to facilitate grinding.

The first step is to grind a "flat" for fixing the supports later.

After that the slots can be drilled out as is shown here. You can see the "safe" extra length on the rod on the right hand side

The next step is the use a cutter for milling the slots to the correct shape. The 6 mm hole can be drilled on one side and 6 mm thread tapped on the other side.

A setting bolt and nuts have to be used now in the chuck so that the ends of the brackets can be turned down to the exact length easily.

The final assembly can be attached over the (quite narrow) rear swinging arm of the TD1B. For other bikes you will have to use thicker stock (bar) material.
