POP Wheel Fitting

Even before I finished my POP I had problems with the wheel rims falling off.  I am very dubious of any glue that claims to be able to stick rubber to metal so I cam up with this drastic solution.  I decided to bolt the types to the rim.  I did this nearly two years ago as so far have experienced no further problems.  An alternate technique would be to use a flexible glue as used on the Burrell's tyres.

My method was to tap 6 4BA blind holes at 60 degree intervals around the circumference of the wheels.  I used a dividing head to ensure accuracy though it may be possible to make some form of template.

This picture shows the finished parts ready for assembly.

Centre drilling at 60 degree intervals using a dividing head, prior to drilling and tapping 4BA. Use the stop on the drill so that all holes drilled to a constant (7mm) depth.

Without removing the rim from the dividing head, mount the rim and drill though 4BA clearance.  After the first hole bolt the rims temporarily in place so that all subsequent holes are in register.

Using a 1/4 inc slot drill counter bore the tyre. So that the screw is just in contact without compressing the tire set the depth stop off a screw temporally screw tightly in place.

After assembly the counter bores are filled using a hot glue gun.  My only concern is the cutting the tyres may cause cracks to propagate in the rubber - time will tell!
