renob123 Posted January 26, 2009 Share Posted January 26, 2009 I'm thinking I want to use a big-rump roast drill bit to bevel the holes in some wheels I drilled. I used a 35/64 drill bit for the hole. Is there an optimal drill bit size to use to bevel the edges so the lug nuts seat properly? Thanks.

Uberoo Posted January 26, 2009 Share Posted January 26, 2009 what is the diameter of the lugnuts? Thats the diameter of the drill bit you need. Link to comment Share on other sites More sharing options...
lostinthe202 Posted January 26, 2009 Share Posted January 26, 2009 Most drill bits have an inclusive angle of 118* or 59* off the center line. You should find out what angle your lug nuts have and buy a countersink to match that. If you can't find what you need locally, you can get it at Mcmaster.com Good Luck!

monstaru Posted January 26, 2009 Share Posted January 26, 2009 "coutersink".it is an actual bit......like 10 bucks for a nice one of machine tool quality from our local supplier.called bixby tool.cheers, brian Link to comment Share on other sites More sharing options...
WoodsWagon Posted January 27, 2009 Share Posted January 27, 2009 Or you put a tapered stone in your die grinder and go to town like I did. I just always tightened the two origional holes firest and then cranked down the "custom" hols. Nevar had a wehel come off. Course mine wer steel, don't know if youre doing aluminum ones.

Greenley Posted January 27, 2009 Share Posted January 27, 2009 I just always tightened the two original holes first and then cranked down the "custom" holes +1 ... never had a problem. Although if i were to drill a new set, i'd do it the right way for peace of mind. Link to comment Share on other sites More sharing options...

renob123 Posted February 2, 2009 Author Share Posted February 2, 2009 I'm thinking I may just want to use some kind of washers and flat bolts, rather than 60 degree lug nuts. Has anyone tried that method? I guess drag racers do something like that. Jacob Link to comment Share on other sites More sharing options...
lostinthe202 Posted February 2, 2009 Share Posted February 2, 2009 Someone will correct me if I'm wrong, but I believe there are two ways of centering wheels, hub-centric which are centered by sitting on a boss (raised portion) on the hub, and centering by tapered lug nuts which center around the stud. If you use flat head nuts and washers on a non hub-centric wheel/hub setup, you won't be able to get your wheel centered properly which will both ride rough and probably loosen up and want to fall off.

Will- Keep in mind that two of the holes are still original, and I can use regular tapered lug nuts for those two holes. Do you think that would be enough? These are for rallyx only, so I'll be driving about 3 minutes at a time, max. Jacob Link to comment Share on other sites More sharing options...
lostinthe202 Posted February 2, 2009 Share Posted February 2, 2009 If you're really driving only 3 minutes at a time, then my guess would be it won't be a problem. But I should follow that up by saying that I don't know squat about rally x so you should seek some other opinions. Good Luck! Will- Link to comment Share on other sites More sharing options...

Can I use washers and flat lugnuts instead of bevelling? Thanks. Jacob Link to comment Share on other sites More sharing options...
monstaru Posted February 4, 2009 Share Posted February 4, 2009 why are you so opposed to beveling?it is really easy, cheap , and a good bit of insurance for you and your rally-x car.... which by they way is going to be taking a beating in those three minutes..........as you know. you are not drag racing,you are rally crossing. i don't think the flat washers would pass tech anyway.cheers, brain Link to comment Share on other sites More sharing options...

Your point about tech is a good one, however. I may end up ordering a countersink later today. Jacob Link to comment Share on other sites More sharing options...
