hi all im doing a 5 stud conversion on my puma, after looking at loads of ways of doing it I have come to the conclusion that all I need to do is re drill the stud pattern on my original hubs and so far has cost me £2.95 for the correct sized drill bit. so far I've only started on one drum to see how it goes but then I will be doing all of them.

here are a couple of pics of the first drill pilot drilled.



I borrowed my dads spare wheel to see if they lined up properly and its good news />





so chaps and chapets what do you think?

Nice

Hope they come out as grate as everything else you`we done so far :=)

Looks good. How difficult is it to ensure that the holes are concentric and that ou minimise run-out ?

[CartMan]

i would think that since the center hole is the corect sice, that concentricety (is that a word?) won't be an issue

Thanks cartman />

the drill im using to drill the holes has a level bubble on the back so you now when its vertical in both directions and im drilling then on a surface I know is level />

I'd be more concerned about the distance between the old and new holes - two of those hole look like being damned closed to the originals.

Done the math on the stresses involved?

Agree, but have you ever seen those diferent ofset rims? They have for exsample one set of 4x100 and one set of 4x108 the holes are realy close to together... Sometimes almost together. I think he'l be fine /> ofcourse, he could always fill the ol hole whit weld...

I can see what your saying about the stresses involved and the stresses are not going to be enough to cause any problems. the fact the stress has been spread from over 4 holes to 5 holes the overall stress has been reduced regardless of any material removed.
