Mine seem to be 11mm on standard rims and 9mm on 20 X 1 3/8.

mines are 11mm too, so thats the drill size i used when i made my own for my ammaco. 

original ones on my race inc i bought off tim march

[BENDYCAT ELEVENTEEN]

so that's to use a 10mm drill to get a 11mm hole - as i thought that the hole had a little tapper on the top ?

any original rim close ups ?


cheers  B 

[john4130]

my original ones didn't have a small countersink, just a straight hole. i did give the ones on my ammaco a little countersink just to get rid of the sharp edge. here's a pic of my originals before i stripped them of the silver ano. sorry not the best pic

And what was your method of drilling ? 

[mattbloke]

a drill and a drill bit works great 

[BENDYCAT ELEVENTEEN]

I was going to use your sharp wit 

[sawzall]

mark out rim then use a 3mm drill bit as a pilot hole then work up in stages to 10-11mm

[BENDYCAT ELEVENTEEN]

and best method to get out flat spots in the rim ?

[Retrodan72]

a drill and a drill bit works great

Looking sweet Poochy, what are they going on ?

[not johndub71]

What about a cone step drill. Nice finish from them.

[BENDYCAT ELEVENTEEN]

t's getting it in straight and maybe making a jig ?

[Rabdul06]

My originals look like they were drilled from inside the rim (obviously on an unbuilt wheel... ) and then a larger drill was used to remove the burrs from the outside where the rim tape goes.

Looks like it was done by a blind monkey on crack though.....

[not johndub71]

Good point bendy. Now, wheres that skyway rim guy, he may have zytel creation on his hands.. in plastic.
